Retirement Savings Calculator

Welcome to the Retirement Savings Calculator! 🎉 This is your one-stop-shop for planning your future nest egg. Let's dive into what this repository has to offer.

About the Project

This nifty tool helps you calculate your retirement savings with just a few clicks. It takes into account your current age, desired retirement age, current savings, annual contributions, and the expected annual return rate. Voilà! You'll get an estimate of your future savings.

What's Inside?

The repository contains a single file:

• retirement_savings_calculator.py: The magic happens here. This Python script uses Streamlit and NumPy to crunch the numbers and give you the results.

How It Works

Here's a peek under the hood at the key components of our calculator:

Importing Libraries

import streamlit as st
import numpy as np

The Calculation Function

This function handles the heavy lifting and ensures everything runs smoothly.

def calculate_retirement_savings(current_age, retirement_age, current_savings, annual_contribution, return_rate):
    try:
        years_to_retirement = retirement_age - current_age
        if years_to_retirement <= 0:
            raise ValueError("Retirement age must be greater than current age.")

        future_value = current_savings
        
        for _ in range(years_to_retirement):
            future_value += annual_contribution
            future_value *= (1 + return_rate)
        
        return future_value
    
    except ValueError as e:
        st.error(f"Value Error: {e}")
        return None
    except Exception as e:
        st.error(f"An unexpected error occurred: {e}")
        return None

Streamlit UI

The user-friendly interface that makes it all possible.

st.title('Retirement Planning Calculator')

current_age = st.number_input('Current Age:', min_value=0, max_value=100, value=30)
retirement_age = st.number_input('Retirement Age:', min_value=current_age, max_value=100, value=65)
current_savings = st.number_input('Current Savings ($):', min_value=0, value=10000)
annual_contribution = st.number_input('Annual Contribution ($):', min_value=0, value=5000)
return_rate = st.number_input('Expected Annual Return Rate (as a decimal):', min_value=0.0, max_value=1.0, value=0.05)

if st.button('Calculate'):
    future_savings = calculate_retirement_savings(current_age, retirement_age, current_savings, annual_contribution, return_rate)
    if future_savings is not None:
        st.write(f'Estimated Retirement Savings: ${future_savings:,.2f}')
    else:
        st.write('Unable to calculate retirement savings due to input error.')
