A savings goal, one month at a time.
Break a savings target into monthly amounts with this free calculator. Try the $5,050 envelope challenge or set a smaller goal that fits your budget.
Make the goal your own
All three fields are required. Use amounts with at most two decimal places and a whole number of months. Enter 0 if nothing is saved yet.
A standard 100-envelope challenge adds $1 through $100: 100 × 101 ÷ 2 = $5,050. You can choose any target and time frame above. Your numbers are not saved.
Set aside each month
(Goal − already saved) ÷ months, rounded up to the nearest cent. No interest, fees, or investment returns assumed. Reduce the goal or extend the time if the amount crowds out essentials.
A useful goal leaves room for essentials.
Choose an amount after accounting for housing, food, healthcare, and required bills. This calculator divides a goal; it does not tell you what you can afford. Check your monthly budget first and build a sinking fund for predictable costs.
