What is the savings goal calculator?
In short
To save $20,000 in 3 years starting from zero, you need $524/month at 4% interest — or $556/month with no interest. Earning even a modest 4% on a high-yield savings account cuts your required monthly contribution by 6%. KalkWise runs the simulation month-by-month and shows the exact date you reach your goal, or the monthly shortfall if your timeline is too tight.
This savings goal calculator works backward from a target. Enter a goal amount and your plan, and it tells you whether and when you'll reach it — or how much more to save each month to get there by your deadline.
How to use this calculator
- 1Enter your savings goal and current savings.
- 2Add your planned monthly contribution and interest rate.
- 3Set the time frame you're aiming for.
- 4See the goal banner: when you'll reach it, or the shortfall.
- 5Adjust the contribution to close any gap.
The formula
- FV
- — Your goal (target amount)
- P
- — Current savings
- PMT
- — Monthly contribution
- r
- — Annual rate (decimal)
- n
- — Compounds per year
- t
- — Time to reach the goal
Because the equation can't be solved cleanly for t when there are contributions, KalkWise simulates each month until the balance reaches your goal.
