Savings Goal Calculator
See how much to save each week, fortnight, or month to hit your target — with or without interest.
Enter your goal amount, current savings, timeframe, and optional interest rate. We’ll calculate the regular contribution needed, total contributions, and the projected future value.
With interest (solving for regular contributions with a starting balance):
PMT = (FV − PV·(1 + r/n)n·t) · (r/n) / ((1 + r/n)n·t − 1)
Without interest: PMT = (FV − PV) / (n·t).
Total contributions = PMT × (n·t).
Copyable Excel & Google Sheets Formulas
Assume: A2 = Goal (FV), B2 = Current (PV), C2 = Annual rate %, D2 = Years, E2 = Periods per year.
Without interest: divide the gap by total periods.
With interest: includes growth on the starting balance.

FAQs
How do I figure out how much to save each week?
Enter your target amount, timeframe, and expected interest rate. The calculator shows how much you need to save weekly or monthly to reach your goal by the deadline.
Does compound interest affect my savings goal?
Yes. If you include interest, your balance compounds over time, reducing the amount you need to deposit each period.
What interest rate should I use?
Use the annual rate for your savings account after fees and taxes. If you’re not sure, set it to 0% for a conservative estimate.
