Savings Calculator

Turn a savings goal into a real number

Saving works best when you can see the finish line. Our Savings Calculator turns your starting balance, monthly contribution, and interest rate into a clear projection of how much you will have—and how much of that growth is interest you did not have to earn the hard way.

What this calculator does

The tool models monthly compound interest on an initial deposit plus equal monthly contributions. It returns three useful numbers: Future Value (your projected account balance), Total Contributed (the money you actually put in), and Interest Earned (the growth paid by your bank or credit union). If you want to explore the math behind the projection, try our Compound Interest Calculator next.

How to use the Savings Calculator

1. Enter your starting balance — the amount already saved, or zero if you are just beginning.
2. Add your monthly contribution — choose a number you can sustain without relying on windfalls.
3. Input the annual interest rate— use your account's APY. High-yield savings accounts often land between 4% and 5%.
4. Set your timeline in years — match it to your goal, whether that is one year or a decade.
5. Review the three result cards — they show your ending balance, total deposits, and interest earned.

Common savings goals

Worked example: five years of steady saving

Imagine you open a high-yield savings account with $1,000, deposit $250 every month, and earn 4.5% APY compounded monthly. After five years, the calculator projects a future value of about $18,039. Of that total, $16,000 is money you contributed and roughly $2,039 is interest the account paid you.

Now compare that to a traditional savings account paying 0.5% APY. With the same deposits, your interest would drop to about $218—an $1,821 difference that costs nothing extra beyond choosing the right account.

Tips to reach your goal faster

• Automate the deposit. Schedule the transfer for the day after payday so you save before you spend.
• Keep short-term money safe. For goals under three years, prioritize liquidity and FDIC insurance over chasing the highest possible yield.
• Compare APY once a year. Online banks regularly adjust rates, and a quick switch can add meaningful interest over time.

For longer-term goals, consider how saving fits with the rest of your financial picture. Use our Retirement Calculator to plan your nest egg, or our Mortgage Calculator to see how a home purchase affects your monthly cash flow.
