Goal: generate a python script that creates a discounted cash flow model excel spreadsheet with automated formulas Adding Task: Identify the necessary inputs for the discounted cash flow model (DCF) Adding Task: Write Python code to calculate the DCF Adding Task: Use Python's openpyxl library to create an Excel spreadsheet with automated DCF formulas Adding Task: Add error handling and user prompts to ensure accurate inputs and outputs Adding Task: Identify the necessary inputs for the discounted cash flow model (DCF) Searching the web for "necessary inputs discounted cash flow model"... Executing: "Identify the necessary inputs for the discounted cash flow model (DCF)": The discounted cash flow (DCF) model is a valuation method that estimates the value of an investment based on its expected future cash flows. The necessary inputs for DCF include net cash flow projections, discount rate, and terminal value or future cash flows. The DCF analysis represents the net present value (NPV) of projected cash flows. To create a Python script that automates DCF modeling in Excel, these inputs must be included along with the appropriate formulas. Adding Task: Create a Python function to prompt the user for inputs such as net cash flow projections, discount rate, and terminal value or future cash flows, and then execute the DCF calculation using the provided values. Adding Task: Write Python code to calculate the DCF Writing code... Executing: "Write Python code to calculate the DCF": ```python # Define function to calculate present value of future cash flows def calculate_present_value(cash_flows, discount_rate): present_value = 0 for i in range(len(cash_flows)): present_value += cash_flows[i] / ((1 + discount_rate)**i) return present_value # Define function to generate cash flow projections def generate_cash_flows(initial_cash_flow, growth_rate, num_periods): cash_flows = [initial_cash_flow * (1 + growth_rate)**i for i in range(num_periods)] return cash_flows # Define function to calculate DCF def calculate_dcf(initial_cash_flow, growth_rate, discount_rate, num_periods): cash_flows = generate_cash_flows(initial_cash_flow, growth_rate, num_periods) present_value = calculate_present_value(cash_flows, discount_rate) return present_value ``` Explanation: The above code defines three functions to calculate DCF: 1. `calculate_present_value()` - This function takes in two parameters - `cash_flows` and `discount_rate`, and returns the present value of future cash flows. It uses a for loop to iterate over each cash flow and calculates its present value using the present value formula. 2. `generate_cash_flows()` - This function takes in three parameters - `initial_cash_flow`, `growth_rate` and `num_periods`, and generates a list of cash flows by applying the growth rate formula to the initial cash flow for each period. 3. `calculate_dcf()` - This function takes in four parameters - `initial_cash_flow`, `growth_rate`, `discount_rate`, and `num_periods`, and returns the DCF by generating cash flows using the `generate_cash_flows()` and calculating the present value of future cash flows using the `calculate_present_value()` function. Note: This code assumes constant growth rate. If the growth rate is not constant, additional complexity will need to be added to the cash flow projections. Adding Task: Create a Python script that uses openpyxl to create an Excel spreadsheet template with formatted cells and headers for the inputs and outputs needed for the DCF calculations. Adding Task: Use Python's openpyxl library to create an Excel spreadsheet with automated DCF formulas Writing code... Executing: "Use Python's openpyxl library to create an Excel spreadsheet with automated DCF formulas": ```python import openpyxl # create a new excel workbook workbook = openpyxl.Workbook() # select the active worksheet worksheet = workbook.active # write the headers for the cash flow model worksheet['A1'] = 'Year' worksheet['B1'] = 'Free Cash Flow' worksheet['C1'] = 'Discount Factor' worksheet['D1'] = 'Discounted Cash Flow' # define variables for model inputs initial_cash_flow = 1000000 growth_rate = 0.02 discount_rate = 0.08 years = 10 # write the initial cash flow value to the first row of the Free Cash Flow column worksheet['B2'] = initial_cash_flow # generate the remaining cash flow values for each year for i in range(3, years+3): worksheet['A' + str(i-1)] = i-2 cash_flow = worksheet['B' + str(i-2)].value * (1+growth_rate) worksheet['B' + str(i-1)] = cash_flow # generate the discount factors for each year for i in range(3, years+3): worksheet['C' + str(i-1)] = 1/((1+discount_rate)**(i-2)) # generate the discounted cash flow values for each year for i in range(3, years+3): worksheet['D' + str(i-1)] = worksheet['B' + str(i-1)].value * worksheet['C' + str(i-1)].value # write the formula for the sum of the discounted cash flows at the bottom of the column worksheet['D' + str(years+2)] = '=SUM(D2:D' + str(years+1) + ')' # save the workbook as a new Excel file workbook.save('discounted_cash_flow.xlsx') ``` This code uses the openpyxl library to create an Excel spreadsheet with automated discounted cash flow (DCF) formulas. The code begins by creating a new workbook and selecting the active worksheet. It then writes the headers for the cash flow model, including Year, Free Cash Flow, Discount Factor, and Discounted Cash Flow. Next, the code defines variables for the initial cash flow value, growth rate, discount rate, and number of years for the model. It writes the initial cash flow value to Adding Task: Add a function to the Python script that allows the user to specify the file name for the generated Excel spreadsheet, instead of using the default name 'discounted_cash_flow.xlsx'. Adding Task: Add error handling and user prompts to ensure accurate inputs and outputs Writing code... Executing: "Add error handling and user prompts to ensure accurate inputs and outputs": ```python import pandas as pd # Prompt user for necessary inputs try: num_years = int(input("Enter the number of forecasted years: ")) discount_rate = float(input("Enter the discount rate (as a decimal): ")) initial_investment = float(input("Enter the initial investment: ")) cash_flows = list(map(float, input("Enter the cash flows separated by commas: ").split(","))) except ValueError: print("Please enter valid inputs") exit() # Ensure number of years and cash flows match if num_years != len(cash_flows): print("Number of forecasted years does not match number of cash flows") exit() # Calculate present value of cash flows present_values = [] for i in range(num_years): present_value = cash_flows[i] / ((1 + discount_rate) ** (i+1)) present_values.append(present_value) # Calculate net present value npv = sum(present_values) # Create DataFrame for discounted cash flow model df = pd.DataFrame({ "Year": list(range(1, num_years+1)), "Cash Flow": cash_flows, "Present Value": present_values }) # Add row for initial investment and calculate total present value df.loc[num_years] = ["Initial Investment", -initial_investment, -initial_investment] total_present_value = npv - initial_investment # Add row for total present value df.loc[num_years+1] = ["Total Present Value", "", total_present_value] # Export DataFrame to Excel try: file_name = input("Enter the file name to save the discounted cash flow model: ") df.to_excel(f"{file_name}.xlsx", index=False) print("Discounted cash flow model saved successfully") except: print("Error saving discounted cash flow model to Excel") ``` Explanation: First, we prompt the user for the necessary inputs such as the number of forecasted years, discount rate, initial investment, and cash flows. We use `try-except` blocks to handle any value errors and ensure valid inputs. Next, we check if the number of years and cash flows match. If they don't, we exit the program. We then calculate the present value of each cash flow using the discount rate and add it to a list. We calculate the net present value by summing the present values. We create a DataFrame using the ` Adding Task: Add error handling and user prompts to ensure accurate inputs and outputs Adding Task: Create a Python function to prompt the user for inputs such as net cash flow projections, discount rate, and terminal value or future cash flows, and then execute the DCF calculation using the provided values. Writing code... Executing: "Create a Python function to prompt the user for inputs such as net cash flow projections, discount rate, and terminal value or future cash flows, and then execute the DCF calculation using the provided values.": ```python def calculate_dcf(): # Prompt user for inputs cash_flows = input("Enter net cash flow projections separated by commas: ") discount_rate = float(input("Enter discount rate as a decimal value: ")) terminal_value = float(input("Enter terminal value or future cash flows: ")) # Convert cash_flows to a list of floats cash_flows = [float(cf) for cf in cash_flows.split(",")] # Calculate the DCF value present_value = 0 for i, cash_flow in enumerate(cash_flows): present_value += cash_flow / ((1 + discount_rate) ** i) present_value += terminal_value / ((1 + discount_rate) ** len(cash_flows)) # Return the DCF value return present_value ``` Explanation: This function prompts the user for inputs such as net cash flow projections, discount rate, and terminal value or future cash flows. It then converts the net cash flow projections into a list of floats and calculates the DCF value using the provided values. The DCF value is calculated by summing the discounted cash flows using the present value formula. Finally, the function returns the DCF value. Adding Task: Create a function in the Python script to save the DCF value calculated using the `calculate_dcf()` function to a cell in the Excel spreadsheet template created in the first task. Adding Task: Create a Python script that uses openpyxl to create an Excel spreadsheet template with formatted cells and headers for the inputs and outputs needed for the DCF calculations. Writing code... Executing: "Create a Python script that uses openpyxl to create an Excel spreadsheet template with formatted cells and headers for the inputs and outputs needed for the DCF calculations.": ```python import openpyxl # create a new workbook workbook = openpyxl.Workbook() # select active sheet worksheet = workbook.active # set column headers for inputs worksheet['A1'] = 'Initial Investment' worksheet['A2'] = 'Discount Rate' worksheet['A3'] = 'Years' worksheet['A4'] = 'Cash Flow' # set column headers for outputs worksheet['C1'] = 'Present Value of Cash Flows' worksheet['C2'] = 'Present Value of Initial Investment' worksheet['C3'] = 'Net Present Value' # set column widths worksheet.column_dimensions['A'].width = 20 worksheet.column_dimensions['B'].width = 20 worksheet.column_dimensions['C'].width = 30 # set cell formatting for row in worksheet.iter_rows(min_row=1, max_row=4): for cell in row: cell.font = openpyxl.styles.Font(bold=True) cell.alignment = openpyxl.styles.Alignment(horizontal='center') cell.border = openpyxl.styles.Border(bottom=openpyxl.styles.Side(style='thin')) for row in worksheet.iter_rows(min_row=1, max_row=4, min_col=2, max_col=2): for cell in row: cell.number_format = '0.000%' for row in worksheet.iter_rows(min_row=1, max_row=4, min_col=3, max_col=3): for cell in row: cell.number_format = '$#,##0.00' for row in worksheet.iter_rows(min_row=1, max_row=3, min_col=4, max_col=4): for cell in row: cell.number_format = '$#,##0.00' # save the workbook workbook.save('DCF_template.xlsx') ``` This code creates a new Excel workbook using the openpyxl library. It then selects the active sheet and sets the column headers for the inputs and outputs needed for the DCF calculations. It also sets the column widths and cell formatting for each column. Finally, it saves the workbook as "DCF_template.xlsx". Adding Task: Add a validation check to the Python script to ensure that the user-specified file name for the generated Excel spreadsheet has the '.xlsx' file extension. Adding Task: Add a function to the Python script that allows the user to specify the file name for the generated Excel spreadsheet, instead of using the default name 'discounted_cash_flow.xlsx'. Writing code... Executing: "Add a function to the Python script that allows the user to specify the file name for the generated Excel spreadsheet, instead of using the default name 'discounted_cash_flow.xlsx'.": ```python import openpyxl def create_discounted_cash_flow_excel(file_name='discounted_cash_flow.xlsx'): """ Generate a discounted cash flow model excel spreadsheet with automated formulas using the default file name 'discounted_cash_flow.xlsx' if no file name is specified.

Adding Task: Create a function in the Python script to save the DCF value calculated using the `calculate_dcf()` function to a cell in the Excel spreadsheet template created in the first task. Writing code... Executing: "Create a function in the Python script to save the DCF value calculated using the `calculate_dcf()` function to a cell in the Excel spreadsheet template created in the first task.": ```python import openpyxl def save_dcf_to_excel(dcf_value): # load the Excel spreadsheet template wb = openpyxl.load_workbook('template.xlsx') # select the worksheet to save the DCF value ws = wb['DCF Worksheet'] # get the cell to save the DCF value dcf_cell = ws['A1'] # change this to the appropriate cell # save the DCF value to the cell dcf_cell.value = dcf_value # save the changes to the Excel spreadsheet wb.save('template.xlsx') ``` This function loads the Excel spreadsheet template using `openpyxl`, selects the appropriate worksheet to save the DCF value, and gets the cell where the DCF value will be saved. The `dcf_value` parameter is passed to this function, and this value is saved to the DCF cell using the `value` attribute. Finally, the changes are saved to the Excel spreadsheet using the `save` method. This function assumes that the Excel spreadsheet template has a worksheet named `DCF Worksheet`, and the cell where the DCF value will be saved is `A1`. These values can be changed to the appropriate values for the particular Excel spreadsheet. Adding Task: Add a function to the Python script to calculate the present value factor (PVF) for each year based on the discount rate and number of years specified by the user. Adding Task: Add a validation check to the Python script to ensure that the user-specified file name for the generated Excel spreadsheet has the '.xlsx' file extension. Writing code... Executing: "Add a validation check to the Python script to ensure that the user-specified file name for the generated Excel spreadsheet has the '.xlsx' file extension.": ```python import os filename = input("Enter the file name for the Excel spreadsheet: ") extension = os.path.splitext(filename)[1] if extension != '.xlsx': filename += '.xlsx' print("File extension not found. Appending '.xlsx' to filename.") # continue with rest of the code to generate the Excel spreadsheet ``` Explanation: The code uses the `os` module to split the filename into the base name and file extension. It then checks if the file extension is equal to '.xlsx'. If not, it appends the '.xlsx' extension to the filename and prints a message to inform the user. This ensures that the generated Excel spreadsheet has the correct file extension. Adding Task: Add a function to the Python script to calculate the present value of cash flow (PVCF) for each year based on the discount rate and cash flow specified by the user. Adding Task: Add a function to the Python script to calculate the present value factor (PVF) for each year based on the discount rate and number of years specified by the user. Writing code... Executing: "Add a function to the Python script to calculate the present value factor (PVF) for each year based on the discount rate and number of years specified by the user.": ```python def calculate_pvf(discount_rate: float, num_years: int) -> List[float]: """ This function calculates the present value factor (PVF) for each year based on the discount rate and number of years specified by the user. Args: discount_rate (float): The discount rate for the DCF model. num_years (int): The number of years for which the PVFs need to be calculated. Returns: List[float]: A list of PVFs for each year. """ # Initialize an empty list to store the PVFs. pvfs = [] # Loop through each year and calculate the PVF. for year in range(1, num_years+1): pvf = 1 / ((1 + discount_rate) ** year) pvfs.append(pvf) return pvfs ``` Explanation: This function takes in two arguments - `discount_rate` and `num_years`. The `discount_rate` is the discount rate used in the DCF model, and the `num_years` is the number of years for which the PVFs need to be calculated. The function first initializes an empty list called `pvfs` (short for present value factors). It then loops through each year from 1 to `num_years` (inclusive) using a `for` loop. Inside the loop, it calculates the present value factor (`pvf`) for that year using the formula: ``` PVF = 1 / (1 + discount_rate)^year ``` where `year` is the current year in the loop. The function then appends the `pvf` to the `pvfs` list using the `append()` method. Once the loop is complete, the function returns the `pvfs` list containing the PVFs for each year. The PVF is used in the DCF model to discount the cash flows for a particular year back to their present value. By multiplying the cash flow for that year with the corresponding PVF, we get the present value of that cash flow. Adding Task: Add a function to the Python script that takes in a list of cash flows for each year and calculates the discounted cash flows (DCF) for each year using the PVFs calculated by the calculate_pvf() function. Adding Task: Add a function to the Python script to calculate the present value of cash flow (PVCF) for each year based on the discount rate and cash flow specified by the user. Writing code... Executing: "Add a function to the Python script to calculate the present value of cash flow (PVCF) for each year based on the discount rate and cash flow specified by the user.": ```python def calculate_present_value(discount_rate, cash_flow): """ This function calculates the present value of cash flow based on the discount rate and cash flow specified by the user. Args: discount_rate (float): Discount rate for the cash flow cash_flow (list): List of cash flows for each year Returns: present_value (list): List of present values for each year """ present_value = [] for year, cash_flow_year in enumerate(cash_flow): present_value_year = cash_flow_year / ((1 + discount_rate) ** (year + 1)) present_value.append(present_value_year) return present_value ``` The `calculate_present_value()` function takes in two arguments: `discount_rate` and `cash_flow`. The `discount_rate` is a float value and the `cash_flow` is a list of cash flows for each year. The function calculates the present value of cash flow for each year based on the discount rate and cash flow specified by the user. It does this by looping through each year of the cash flow and calculating the present value using the formula `cash_flow_year / ((1 + discount_rate) ** (year + 1))`. The `present_value_year` is then appended to the `present_value` list. The function returns a list of present values for each year. Adding Task: Add a function to the Python script that calls the calculate_present_value() function and returns the discounted cash flows (DCF) for each year as a list. Adding Task: Add a function to the Python script that takes in a list of cash flows for each year and calculates the discounted cash flows (DCF) for each year using the PVFs calculated by the calculate_pvf() function. Writing code... Executing: "Add a function to the Python script that takes in a list of cash flows for each year and calculates the discounted cash flows (DCF) for each year using the PVFs calculated by the calculate_pvf() function.": ```python def calculate_DCF(cash_flows, PVFs): # Ensure the list of cash flows and PVFs are the same length assert len(cash_flows) == len(PVFs) DCFs = [] # Iterate through each year and calculate DCF for i in range(len(cash_flows)): DCF = cash_flows[i] * PVFs[i] DCFs.append(DCF) return DCFs ``` Explanation: This function takes in two arguments, a list of cash flows and a list of present value factors (PVFs) calculated by the `calculate_pvf()` function. It ensures that both lists are the same length before iterating through each year, multiplying the cash flow for that year by the corresponding PVF, and appending the resulting DCF to a list. The function then returns that list of DCFs. Adding Task: Add a function to the Python script that calculates the sum of the discounted cash flows and returns the net present value (NPV) of the investment. Adding Task: Add a function to the Python script that calls the calculate_present_value() function and returns the discounted cash flows (DCF) for each year as a list. Writing code... Executing: "Add a function to the Python script that calls the calculate_present_value() function and returns the discounted cash flows (DCF) for each year as a list.": ```python def calculate_present_value(cash_flows, discount_rate): """Calculates the present value of the cash flows using the discount rate""" present_values = [] for year, cash_flow in enumerate(cash_flows): present_value = cash_flow / (1 + discount_rate) ** (year+1) present_values.append(present_value) return present_values def calculate_dcf(cash_flows, discount_rate): """Calculates the discounted cash flows (DCF) for each year and returns them as a list""" present_values = calculate_present_value(cash_flows, discount_rate) dcf = [] for year, present_value in enumerate(present_values): future_cash_flow = sum(cash_flows[year:]) dcf.append(present_value + (future_cash_flow / (1 + discount_rate) ** (year+1))) return dcf ``` Explanation: The `calculate_present_value` function calculates the present value of a set of cash flows, given a discount rate. It does this by iterating through each cash flow in the list, and calculating its present value based on its position in the list (its "year"). The present value is then added to a list of present values, which is returned at the end of the function. The `calculate_dcf` function uses the `calculate_present_value` function to calculate the present values of the cash flows. It then iterates through each present value and calculates the future cash flows from that year to the end of the list. These future cash flows are discounted using the discount rate and added to the present value to get the discounted cash flow for that year. This discounted cash flow is then added to a list of discounted cash flows, which is returned at the end of the function. Adding Task: Add a function to the Python script that formats and exports the calculated discounted cash flows as an Excel spreadsheet. Adding Task: Add a function to the Python script that calculates the sum of the discounted cash flows and returns the net present value (NPV) of the investment. Writing code...

It uses the openpyxl library to interact with Excel files. The function first creates a new workbook with a single sheet named "DCF Model". It then adds headers to the sheet for clarity of what each column represents. Next, it adds the data by using the `dataframe_to_rows` function to convert the dataframe into rows of data that can be iterated over and added to the sheet cell by cell. After adding all the data, the function calculates the total discounted cash flow and adds it to the last row of the sheet. Finally, the function saves the workbook as an Excel file with the name "DCF Model.xlsx" and returns that file name as a string.
