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.
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.

Most savings tools ask the forward question — "given a deposit, what will I have?" This tool asks the more useful backward question: "given a goal and a deadline, how much do I need to set aside each month?" You enter the target amount, how much you have already saved, the expected annual return, and the number of years; it solves for the required monthly deposit, then projects your balance year by year against a goal line so you can see when the target becomes reachable. It supports both start-of-month and end-of-month deposit timing. Everything is computed locally in your browser.
(1) Your current balance grows on its own — its future value is balance × (1 + monthly rate)^months. (2) Each monthly deposit also compounds, so the remaining gap is funded by an annuity of monthly contributions. (3) The calculator isolates the monthly deposit that makes balance growth plus contributions equal your target on the deadline. (4) Using that value it replays a month-by-month simulation to draw the yearly projection and the goal line. Because returns are never certain, treat the number as a planning target, not a promise — and adjust either the monthly amount or the timeline as reality unfolds.
The preset buttons encode sensible defaults, but the two inputs that deserve the most scrutiny are the return and the deadline. For goals under three years — emergency funds, car down payments, weddings — use savings-grade returns (3–5%) and keep the balance in deposits, because a market dip right before the deadline is a risk the math cannot absorb. For goals five years and beyond — a house down payment being the borderline case — a diversified portfolio's historical 6–8% becomes defensible. The deadline lever is the quieter one: stretching a $20,000 goal from 4 to 5 years cuts the required deposit by roughly a quarter, while raising the assumed return rarely moves it double digits. One more habit worth building: save each goal as a snapshot, then re-run the calculator quarterly — actual balances versus the projection line tell you quickly whether to raise the deposit or relax the date.
Determines the monthly deposit that, together with your current balance compounding to the target date, reaches your goal. It works backward from the target: balance and every deposit grow at the expected annual return, and it solves for the single monthly amount that closes the gap.
It can, but at planning horizons of a few years the effect is often modest. Shifting an expected return from 4% to 7% barely moves a 4-year number, while extending the timeline 2–3 years changes the requirement far more. The tool makes both levers explicit.
No. The monthly deposit and year-by-year balance are nominal values that ignore inflation. For an inflation-adjusted view, pair this tool with the Compound Interest calculator's real-value readout.
The standard guidance is 3–6 months of essential expenses — use the preset in this calculator as a starting point, then refine with your real monthly costs. Keep the money in a high-yield savings account, not stocks, since the emergency date is unpredictable even when the amount is not.
Yes. Money needed within about 3 years should assume savings-account or CD rates (roughly 3–5%), not stock-market returns — a down payment due in 2 years cannot wait out a bear market. Reserve equity-like return assumptions (6–8%) for goals 7+ years out.
