Savings Goal Calculator
Enter a target amount and date to see the weekly or monthly contribution needed. Add current savings and an optional growth rate for a more complete estimate.
How much do you need to save?
The calculator solves for the regular contribution needed to reach your target. With a 0% rate, it subtracts current savings from the goal and divides the remainder by the weekly or monthly periods available. With a positive rate, it uses a compound-growth annuity formula.
Example
A 5,000 target with 500 already saved and 18 months remaining needs 250 per month at 0% interest. A positive assumed rate may lower the estimated contribution, but real rates can change and returns are not guaranteed.
Use a realistic plan
Choose a date that leaves room for irregular expenses, use 0% when you want a conservative baseline, and automate the contribution if possible. This tool is educational, not financial advice.

Frequently asked questions
How much should I save each month to reach a goal?
At 0% interest, subtract current savings from the goal and divide by the months remaining. The calculator can also include an optional rate.
Should I include interest?
Use 0% for a conservative plan. If you enter a rate, treat it as an estimate rather than a guarantee.
What if I already have enough saved?
The required new contribution is zero when current savings, including estimated growth, meet the goal.
