financecalculator is a Python package for calculating financial metrics specifically designed for loans or investment scenarios.
This package serves as a convenient tool for managing personal finances, offering functionalities such as Periodic Payment (contribution) Calculation, Future Value (FV) Calculation, Present Value (PV) Calculation, and Frequency (N) Calculation.

$ pip install financecalculatorThis package offers four key functions:
-
contribution Calculation
calculate_contribution(principal, future_value, annual_rate, n_periods)
Calculates the periodic payment (contribution) required to pay off a loan or reach a specified future value over a given number of periods.
-
FV Calculation
future_value(principal, annual_rate, n_periods, contribution=0)
Calculates the future value of an investment or loan, factoring in optional periodic contributions.
-
PV Calculation
present_value(principal, annual_rate, n_periods, contribution=0)
Calculates the present value of an investment or loan, considering optional monthly contributions.
-
N Calculation
n_periods(principal, annual_rate, future_value, contribution=0)
Calculates the number of periods (in months) required to reach a specified future value, given an initial principal, an annual interest rate, and optional monthly contributions.
-
principal(float):
The initial investment or loan amount (also known as Present Value in financial terms). -
future_value(float):
The desired amount at the end of the calculation period (e.g., remaining loan balance or target savings). -
annual_rate(float):
Annual interest rate expressed as a percentage (e.g., 5 for 5%). -
n_periods(int):
Total number of periods (typically in months) over which the calculation will be performed. -
contribution(float, optional):
The amount paid or contributed per period (e.g., monthly contributions). Defaults to 0 if not provided.
The financial calculator project situates itself within the Python ecosystem as a learning-oriented initiative aimed at developing practical skills in financial computation and programming. While the Python ecosystem already includes robust packages and applications like Loan Calculator and Financial Calculator App, this project differentiates itself by offering an accessible, user-friendly tools that simplifies core financial concepts. With intuitive function names like calculate_contribution, future_value, and present_value, it allows users — especially beginners and students — to quickly grasp the essentials without needing to understand complex financial formulas. This project also serves as a hands-on exercise for those eager to deepen their understanding of both finance and Python programming, making it a valuable resource for anyone looking to deepen their understanding of financial concepts and Python development.
The financecalculator package allows users to perform essential financial calculations conveniently. Below are some examples of how to use this package:
from financecalculator import calculate_contribution, future_value, present_value, n_periods
# Calculate periodic payments for a loan
payment = calculate_contribution(principal=20000, future_value=0, annual_rate=5, n_periods=24)
# Calculate future value of an investment
fv = future_value(principal=5000, annual_rate=7, n_periods=36, contribution=200)
# Calculate present value for a target amount
pv = present_value(principal=0, annual_rate=4, n_periods=12, contribution=500)
# Calculate the number of months to reach a goal
months = n_periods(principal=10000, annual_rate=6, future_value=50000, contribution=300)Interested in contributing? Check out the contributing guidelines. Please note that this project is released with a Code of Conduct. By contributing to this project, you agree to abide by its terms.
