How Much Should You Save Each Month?
This calculator works backward from a target: you tell it your goal amount, how much you already have saved, your expected annual interest rate, and your timeline — and it tells you the exact monthly deposit needed to hit that goal, accounting for the interest your savings will earn along the way.
Why Interest Reduces Your Required Monthly Deposit
If your savings earn interest, you don't need to save the full goal amount yourself — interest does part of the work. The longer your timeline and the higher your rate, the more interest contributes, meaning your required monthly deposit can be meaningfully lower than simply dividing your goal by the number of months.
Common Savings Goals This Calculator Helps With
- Home down payment — pair this with our Mortgage Calculator to plan both your savings timeline and your eventual monthly payment.
- Emergency fund — most experts recommend 3–6 months of essential expenses saved in an accessible account.
- Education or wedding fund — set a target date and let the calculator show your required monthly contribution.
- Retirement savings — for long timelines, even modest monthly amounts compound significantly over 20–30 years.
A Tip for Staying on Track
Automating your monthly transfer the day you get paid — rather than saving "whatever's left over" at month-end — is one of the most reliable ways to actually hit a savings goal. Treat your monthly savings amount as a fixed bill you pay to your future self.
