Project your wealth with compound interest, plan contributions, and see how your money grows over time. Free, powerful tools for smart financial planning.
Building wealth comes down to a few simple ideas done consistently: invest regularly, let compound interest work, and give it time. Our investment calculators help you visualize exactly how your money can grow — so you can set realistic goals and stay motivated to reach them.
Project compound interest growth with an initial amount, monthly contributions, and expected return. Includes a growth chart, contributions vs. interest breakdown, and year-by-year table.

RelatedIt's hard to stay motivated saving small amounts when the payoff is decades away. An investment calculator makes the future tangible — it shows you that $500 a month really can become hundreds of thousands of dollars, and that the boring habit of consistent investing is genuinely powerful. Seeing the numbers helps you commit.
It also helps you plan realistically. By adjusting your contributions, return rate, and time horizon, you can find a path to your goal — whether that's retirement, a house down payment, or financial independence — and understand the tradeoffs between saving more, earning more, or investing longer.
| $300/month at 7% | Total Invested | Future Value |
|---|---|---|
| After 10 years | $36,000 | ~$52,000 |
| After 20 years | $72,000 | ~$157,000 |
| After 30 years | $108,000 | ~$367,000 |
| After 40 years | $144,000 | ~$787,000 |
Notice how the gap between what you invest and what you end up with grows dramatically over time. That gap is compound interest. Use our Investment Calculator to model your own numbers.

No. The calculator uses an assumed return rate you enter, but real investment returns vary and are never guaranteed. Markets go up and down. Use conservative estimates for planning and remember that past performance doesn't predict future results.
