See exactly how your wealth grows over time. Instantly track how consistent monthly contributions and compound interest combine to accelerate your investments.
Compound interest can be confusing to wrap your head around. Our dashboard splits your final "Future Value" into two clear buckets: The hard cash you deposited, and the interest the bank paid you on top of it.
Instead of relying on basic approximation formulas, our calculator loops through every single month of your timeline. It adds your contribution first, and applies compounding logic correctly to ensure pinpoint financial accuracy.
Watch your future wealth grow in real-time as you tweak your monthly inputs. By removing the clunky "Calculate" button, you can rapidly test different scenarios and interest rates without waiting for a webpage to reload.
Your private financial estimates are never uploaded or tracked. The entirety of the math happens locally inside your browser, meaning it is perfectly safe to use and even functions fully when disconnected from the internet.
Compound interest is the interest on your deposit, plus the accumulated interest from previous periods. Basically, you earn "interest on your interest." Over long periods—like 20 or 30 years—this causes your wealth to grow exponentially, rather than in a straight line.
Compound frequency is how often the bank applies the interest to your balance. If an account is compounded Monthly, your interest begins generating its own new interest starting the very next month. Monthly compounding will result in slightly higher long-term earnings than Annual compounding.
Yes, absolutely. While the stock market does not guarantee a fixed interest rate every year, you can enter a historically estimated annual return (for example, the S&P 500 historically averages around 7% to 10% annually). Just set your Compound Frequency to "Annually" to get an estimated future target.
