This savings calculator projects how your money grows with compound interest and regular deposits. Enter what you have saved now, what you add each month and your account’s interest rate (APY) to see your future balance, total contributions and total interest earned — plus how long a savings goal will take.
What Is a Savings Calculator?
A savings calculator estimates the future value of a savings account based on three things: how much you start with, how much you add regularly, and the interest rate the account pays. Because savings accounts pay interest on your interest too — compound interest — the growth accelerates over time. This calculator makes that growth concrete, so you can set a realistic goal for an emergency fund, a house deposit, a car or a vacation.
For a deeper look at compounding itself, use our Compound Interest Calculator. To compare account rates properly, our APY Calculator explains the rate banks advertise.
How to Use This Savings Calculator
- Initial deposit: what is in the account today (enter 0 if you are starting from scratch).
- Monthly deposit: what you will add every month. Automating this on payday is the habit that makes the projection real.
- Annual interest rate / APY: the rate on your savings account. High-yield savings accounts paid around 4–5% APY in recent years, while traditional accounts often pay under 1% — the difference matters, as the example below shows.
- Years to save: your time horizon.
- Savings goal (optional): enter a target amount and the calculator tells you when you will reach it at this pace.
Savings Calculator Example (Verified Numbers)
Start with $1,000, add $200 a month at 4.5% APY for 10 years:
- Future balance: $31,648.10
- Total you contributed: $25,000
- Interest earned: $6,648.10 — money the account paid you
At a 0.5% traditional-account rate instead, the same deposits would grow to only about $25,700. The rate gap alone is worth roughly $6,000 over the decade, which is why comparing APY matters. When your goal is long-term investing rather than a savings account, our Investment Calculator models market-style returns, and the Retirement Calculator projects decades ahead.
How Compound Interest Grows Your Savings
With monthly deposits and monthly compounding, the future value is:
FV = P(1 + r)n + PMT × [((1 + r)n − 1) ÷ r]
where P is the initial deposit, PMT the monthly deposit, r the monthly rate (derived from APY), and n the number of months. The first term is your starting money growing; the second is all your deposits plus the interest they each earned. Early on, deposits do most of the work. Given enough years, interest takes over — that crossover is the moment savers feel compounding “click”.

Frequently Asked Questions
How much should I save each month?
A common guideline is the 50/30/20 budget: about 20% of take-home pay toward savings and debt payoff. This calculator matters more than the rule — enter what you can actually sustain and watch the outcome.
What is a good APY for a savings account?
High-yield savings accounts have recently offered around 4–5% APY, versus a national average well under 1% for traditional accounts. Always compare APY, not the nominal interest rate.
Does this calculator include taxes or inflation?
No. Interest on savings is taxed as income, and inflation reduces real purchasing power. Treat the result as the account balance, not future buying power.
How long will it take to save $50,000?
Enter $50,000 in the goal field with your deposit and rate. At $200/month and 4.5% APY starting from $1,000, the goal takes a little over 14 years; at $400/month it drops to roughly 8 years.
Is a savings account better than investing?
For goals under about 3 years and for emergency funds, yes — the balance does not fall with the market. For long-term goals, investing historically grows faster but carries risk.
Is this savings calculator free?
Yes — free, instant and no sign-up required.
