See how a monthly savings habit grows over time — or work backwards from a goal to find out exactly how much you need to set aside each month to get there, with compound interest doing part of the work.

How FinanHelp's Savings Calculator Doubles as a Compound Interest Calculator
The formulas and reasoning behind every projection above
Our savings calculator helps you answer one of the most important questions in personal finance: how much will my money actually grow? Whether you're building an emergency fund, saving for a down payment, or investing for retirement, this tool shows you exactly how monthly contributions and compound interest work together over time.
Simply enter your starting balance, how much you plan to save each month, your expected annual return, and your time horizon. The savings calculator instantly projects your final balance, breaks down how much comes from your own contributions versus interest earned, and gives you a year-by-year table you can export.
How does the savings calculator work?
This savings calculator uses monthly compounding to project your balance. Each month, your existing balance earns interest based on your expected annual return, and your new contribution is added on top. Over years or decades, this compounding effect can account for a surprisingly large share of your final total — often more than the money you contributed yourself.
- Growth mode: enter a monthly contribution to see your final balance.
- Goal mode: enter a goal to see the contribution needed to reach it.
Why use a savings calculator before you start saving?
Setting a savings goal without running the numbers first is a common mistake. A savings calculator removes the guesswork by showing you, in concrete dollar terms, what different contribution levels and time horizons actually produce. According to the Consumer Financial Protection Bureau, having a clear savings plan is one of the strongest predictors of building an adequate financial cushion.
The power of compound interest: why a compound interest calculator matters
Compound interest means you earn returns not only on the money you put in, but also on the interest that money has already earned. As the U.S. Securities and Exchange Commission explains, this effect accelerates the longer your money stays invested — which is why starting early matters more than starting with a large amount.
Choosing a realistic annual return
Your results are only as good as your assumptions. A high-yield savings account might return 4–5% annually, while a diversified investment portfolio has historically returned closer to 7% after inflation over the long term, according to data compiled by the Federal Reserve. Try running the savings calculator with a conservative and an optimistic return side by side to see the range of outcomes.
Tips to get more out of your savings plan
- Automate your monthly contribution so saving happens before you have a chance to spend it.
- Revisit your savings calculator projection every year and adjust for raises, bonuses, or changed goals.
- Keep short-term savings in low-risk accounts and long-term savings in growth-oriented investments.
- Use goal mode to reverse-engineer the exact monthly amount a big purchase or milestone requires.
Estimate only, not financial advice. Assumes a constant monthly return and ignores taxes, fees, and inflation.
