Number Savings Goal Calculator
Have a number and a deadline? This tells you exactly how much to save each month to hit your target — with interest doing part of the work.
| Total you'll deposit | $0 |
| Interest earned | $0 |
| Final balance | $0 |
How it works
With monthly rate r over n months, the required deposit is PMT = (FV − PV×(1+r)n) × r / ((1+r)n − 1). Your starting balance grows with compound interest, and each deposit compounds from the month it's made — so earlier months work harder than later ones.
Frequently asked questions
Why does starting early matter so much?
Compound interest rewards time: at 4%, starting with $1,000 and saving for 12 months earns you free money from interest — the longer the timeline, the more the account pays you to save.
Where should I keep goal savings?
A high-yield savings account (typically 4–5% APY as of 2026) beats a checking account and keeps the money liquid and FDIC-insured. Try 0.5% vs 4.5% above to see the difference.
What if I fall behind?
Recalculate with your new starting balance and remaining months — the monthly number will rise, but catching up now beats starting over later.
