How to use it
A quick estimate, without the spreadsheet.
Inputs and units
Enter a single debt balance, APR and monthly repayment amount.
Formula
The balance is advanced month by month: next balance = current balance + monthly interest − payment.
Worked example
$600 at 0% with $100 monthly payments takes six months.
Assumptions and limitations
This is a single-debt schedule, not a multi-debt snowball or avalanche planner. Payments must cover monthly interest to reduce a positive balance.
