How many months of saving it takes to reach a number you have in mind
Estimates only, not financial advice. What you type stays on your device. Updated on 25 Oct 2026.Saving towards a specific number changes the question: not what will this be worth, but when will it be enough. Enter the target, what is in the account now and what goes in each month, and the answer comes back as a month count rather than a balance. Raising the monthly amount moves it immediately, which makes the trade-off between saving more and waiting longer visible instead of theoretical.
The page opens with a $10,000 "Target to reach"; change it to your own goal.
Type what is "In the account now" and what is "Paid in every month".
Type the rate your account pays in "APY".
Read the month count in the goal note, and raise "Paid in every month" to see it come sooner.
Enter an opening balance, a monthly amount and the APY on your own account. The result is the balance at the end, split into what you paid in and what the bank paid you, with a row for every year.
Three things are optional. A goal turns the question round: instead of what will this be worth, how many months until it is enough. A marginal tax rate shows what is left after tax, since savings interest is ordinary income in the year it is credited. An inflation figure shows what the final balance buys in today's money, and says plainly when inflation is beating the rate, because an emergency fund losing slowly to inflation is still the right place for money you might need this week.
One number is worth more than the headline: the month at which interest first exceeds the monthly deposit. That is when the account starts doing more of the work than you do, and almost nobody calculates it by hand. Estimates only, not financial advice.

Rates follow the central bank, change without notice and differ by bank and balance tier. Any figure published here would be out of date within weeks and wrong for your own bank on the day you read it, so the rate you enter is the one from the offer in front of you.
Compare the two APYs here and look at the difference over five years. A percentage point on 20,000 is about 1,000 over that period, which is worth the afternoon it takes to open an account. Check the rate is not an introductory one that drops after six months.
Enter the target as a goal and the answer comes back as a number of months rather than a balance. Raising the monthly deposit moves that number immediately, which makes the choice between saving more and waiting longer a visible trade-off rather than a guess.
Yes, even when inflation is above the rate. An emergency fund is judged on being available the same day without a loss, not on returns. The calculator says when inflation is beating your rate so the cost is visible, but the alternative is worse when the money is needed suddenly.
Formula only: no rates or limits are read from an official source.
