Investment Calculator
Use this free Investment Calculator to project the future growth of your portfolio. Simple, accurate, and easy to use for long-term planning.
Investing is the key to building long-term wealth, and the Investment Calculator is your roadmap. It helps you project how your initial capital, combined with regular monthly contributions, can grow over time given a specific rate of return.
Unlike simple savings, investments in the stock market, real estate, or mutual funds benefit from the powerful force of compounding. This tool allows you to simulate various scenarios—conservative, moderate, or aggressive—to see if you are on track to meet your financial goals.

Frequently Asked Questions
What constitutes a good return rate?
The S&P 500 historically averages about 10% annually before inflation.
Does this include inflation?
No, this calculates nominal value. To see 'real' purchasing power, subtract inflation (avg 3%) from your return rate.
Why is the graph curved?
That curve represents exponential growth, where interest earns interest.
