Free calculator at https://backpr.com/tools/payment-plan-calculator. It runs in your browser; nothing you enter is sent to BackPR.

Enter the total cost, the deposit and how many payments you want. Get an installment schedule with dates and amounts that add up exactly.

### How it works
The balance after the deposit is split into equal payments in whole cents. If it doesn't divide evenly, the last payment carries the extra cents, so the schedule always adds up to the total.

Weekly and every-other-week plans count forward from the first payment date. Monthly plans fall on the same day each month.

**Can BackPR collect payment plans automatically?**
Yes. You set deposits and installment schedules per program, and the family's saved payment method is charged automatically on each date. Nonprofits pay nothing to BackPR for this.

**How many payments should a plan have?**
Many programs end the plan before the program starts, so the full fee is paid by the first day. This calculator lets you try different numbers of payments and see the amounts.
