If you’re looking to grow your savings and build wealth over time, understanding how your money compounds is essential. This Investment Calculator helps you estimate how much your investment could be worth in the future. Whether you’re saving for retirement, a home, or another goal, this tool gives you a clear view of your financial growth over time.
How It Works
The calculator factors in four key inputs:
Initial Investment – The amount of money you start with.
Monthly Contribution – How much you plan to add each month.
Years to Invest – The length of time you plan to keep your money invested.
Expected Annual Return – The percentage of growth you expect per year, on average.
With these values, the calculator estimates:
Future Value – The total value of your investment after the selected period.
Total Contributions – The total amount of money you’ve put in.
Total Interest – The total growth earned through compound interest.
The Power of Compounding
This calculator shows the effect of compound interest over time. As your investment grows, you earn returns not just on your contributions, but also on the interest that accumulates. The longer you stay invested, the more your money can grow.
For example, with an initial investment of $10,000, monthly contributions of $500, a 7% annual return, and a 10-year timeframe, the calculator projects a significant increase in value due to compounding.
Why Use This Tool
Quick Financial Planning – Instantly see how much your savings could grow.
Goal Setting – Adjust your contributions or timeline to hit financial goals.

Frequently Asked Questions
What is a realistic annual return to assume?
For a diversified stock portfolio, 7–10% nominal (before inflation) is the long-run historical average; 5–7% after inflation is a common planning assumption. For conservative projections, use 6%. Past performance never guarantees future results.
Does this calculator account for taxes and fees?
No — the projection is pre-tax and before investment fees. In a taxable account, capital gains and dividend taxes reduce net returns; fund expense ratios (often 0.03–1%) also drag on growth. Treat the result as an upper-bound estimate.
How do monthly contributions affect the final value?
Enormously — regular contributions often matter more than the return rate. For example, $500/month for 30 years at 7% grows to about $566,000, of which only $180,000 is contributions. Starting early beats chasing higher returns.
