How Long Will It Take to Save? — Savings Goal Calculator
Enter a savings goal, your starting balance, and a monthly deposit to see exactly how long it will take — including compound interest. Compare deposit amounts instantly.
"Can I afford the down payment by next June?" is a math question with three inputs: the target, what you have, and what you can put aside monthly. The answer also depends on interest — a 4% APY savings account quietly shortens the timeline compared to cash under the mattress.
Enter your goal and monthly contribution to get the number of months (and the calendar date you will get there), with compound growth included. Then test alternatives: an extra $100 a month, a slightly lower target, or a better rate — and see exactly how many months each one buys back.

Savings Goal Calculator
Work backward from a target: how much to set aside each month — and when a goal becomes reachable — given your current balance and expected return.
The calculator assumes a fixed monthly compounding rate from your expected annual return. Actual returns vary, and the figure is a planning estimate — not a guarantee. Contributions and returns are not inflation-adjusted here. For a projection that accounts for inflation, pair this with the Compound Interest tool's real-value view.
Saving backward, from goal to action
A target date asked backwards answers the question that matters: how much per month? This calculator takes the future value formula for a growing balance — your current savings grows on its own, and each monthly deposit compounds into it — and solves for the one unknown you control. The flip side: if a monthly amount feels too high, nudge the timeline out or the return expectation down and watch the required deposit fall.
You want a $20,000 emergency fund in 4 years. You already have $4,000 saved and expect a 6% annual return.
- Balance growth:$4,000 × (1 + 0.06/12)^48 ≈ $5,082 from savings alone
- Gap:$20,000 − $5,082 = $14,918 to fund with deposits
- Required deposit:≈ $276/month over 48 months at 6% APY
- Reality check:At 4% it rises to ≈ $295/month — and stretched to 5 years it falls to ≈ $209/month. The timeline and return move the number more than you might expect.

Frequently asked questions
How long does it take to save $20,000?
At $500 a month with no interest it takes 40 months — three years and four months. At $750 a month, about 27 months. Add a 4% APY and the $500 plan finishes roughly two months earlier. Run your own numbers in the calculator to include your actual starting balance and rate.
How much should I save each month?
A common framework is 50/30/20: 20% of take-home pay toward savings and debt goals. What matters more is matching the monthly amount to a deadline — work backwards from the goal date, and if the required deposit feels impossible, extend the timeline or lower the target rather than abandoning the plan.
