Find out how long it takes to reach a savings goal given your current balance, monthly contribution, and expected return — or see how interest accelerates your timeline. Plan for any target.
Time to reach your target
A savings goal calculator turns a target — a down payment, a wedding, a dream trip, or a financial cushion — into a concrete timeline. Given your current balance, how much you add each month, and the return your money earns, it counts the months until you cross the finish line. Interest compounds along the way, so a higher return or larger monthly contribution can shave years off the journey.
The two biggest levers are your monthly contribution and your time horizon. Saving $500/month versus $300/month toward a $30,000 goal can mean reaching it years sooner. A modest return (4–5% in a high-yield savings account) also helps, though for short-term goals the contribution matters far more than the rate. This calculator shows your timeline plus how much of the final balance comes from your contributions versus earned interest.
For short-term goals, how much you save monthly matters far more than the interest rate.
A high-yield savings account (4–5% APY) adds free progress with no risk to your principal.
Set up an automatic monthly transfer so the goal funds itself — consistency beats willpower.
Working out what to save each month for a target is the future value annuity formula solved backwards. Interest does part of the work, so the required deposit is always less than the goal divided by the number of months — and the longer the horizon, the larger the share interest carries. If you already have something saved, that balance compounds on its own and reduces what the contributions must achieve, which is why it is subtracted from the target before the annuity factor is applied.
PMT = (Goal − P(1 + r)^n) × r ÷ [ (1 + r)^n − 1 ]with no starting balance this reduces to PMT = Goal × r ÷ [ (1 + r)^n − 1 ]where:
Assumptions: Assumes a steady return and deposits made on schedule. For a short goal, a guaranteed rate is the realistic input — market returns over one to three years are far too variable to plan a dated target around.
You want $40,000 for a deposit in five years, already have $6,000 set aside, and can earn 4% a year compounded monthly.
Result$493 a month
You will deposit $29,570 over the five years; interest supplies the remaining $3,104. Without the $6,000 head start the requirement rises to $603 a month — the existing balance is worth $110 a month of contributions.
