A savings calculator shows how a savings account balance can grow over time with an initial deposit, regular monthly deposits, and compound interest. It's useful for planning toward a savings goal — an emergency fund, a down payment, or a big purchase — by projecting how much you'll have after a set number of years at a given interest rate.
This calculator compounds interest monthly. Each month, interest is calculated on the current balance, then your monthly deposit is added before the next month's interest is calculated.
Formula (with monthly deposits): Balance grows each month as Balance = Balance × (1 + r) + deposit, where r is the annual interest rate ÷ 12.
Example: Starting with a $1,000 initial deposit, adding $250 per month, at a 4% annual interest rate (example rate — enter your bank's actual rate) over 10 years, the balance grows to roughly $37,800 — of which about $31,000 came from deposits and the rest from interest. (Note: all figures in this example are for illustration purposes only and do not represent current or actual bank rates.)
Savings account interest rates in the US vary significantly between traditional banks, which often pay very low rates, and high-yield savings accounts (HYSA) or online banks, which can pay several times more — the 4% default in this calculator is an example reflecting a higher-yield account, not a guaranteed or typical rate (example rate used in this calculator — actual rates vary by bank and change frequently with market conditions). Other options like certificates of deposit (CDs) and money market accounts may offer different rates and terms, often with restrictions on withdrawals.
APY (Annual Percentage Yield) reflects the effect of compounding over a year, so it's typically slightly higher than the stated annual interest rate when compounding more often than annually. This calculator uses your entered rate as the annual rate compounded monthly.
No — the default rate is an example only. Savings account rates vary widely between banks and account types, and change frequently with market conditions. Check your bank's current rate for an accurate projection.
This calculator compounds interest monthly, which is common for savings accounts. Each month, interest is added to the balance before the next month's interest is calculated.
No. Interest earned on savings accounts is generally taxable as income. This calculator shows the gross balance growth before any taxes you may owe on the interest earned.
You can use it for a general estimate, but certificates of deposit (CDs) often have fixed terms and penalties for early withdrawal, and money market accounts may have different rate structures — check the specific terms of those products for accuracy.
The two levers you control are your monthly deposit amount and finding a higher interest rate account. Increasing either — even modestly — can meaningfully shorten the time it takes to reach a savings goal.
