Tool details and privacy
The down payment is subtracted first, then the rest is split. Leftover cents go on the last installment so the total is exact.
If you enter a date, each payment is that many months from the start. A missing day uses the last day of that month.
Options
- Leave the down payment empty and it counts as zero. Leave the months empty for a one-month interval. With no date, no dates are shown.
Limits
- Amounts use two decimal places and up to 12 digits before the decimal point. Rounding is half up.
- 1,250 is rejected. Write 1250 or 1250.50.
- The limit is 60 payments and the interval is 1 to 24 months. No interest is calculated.
