Your monthly repayment scenario

Your monthly payment is the total sent to the creditor, including money used for the fee. Don't enter a loan-only payment here. If the fee is collected separately, include it in the total budget first.

Current outstanding debt balance (R)R0,01 to R50 000 000. Your reported balance, without account or creditor details.

Nominal annual interest rate (%)0 to 100%, with up to two decimals. This model charges the nominal yearly rate divided by 12 each month.

Total normal monthly payment budget (R)R0,01 to R2 000 000. Total sent to the creditor, including money used to cover the fee.

Monthly fee charged to the account (R)R0 to R20 000. Enter 0 if none. The fee is paid from your total payment budget, never on top of it.

Extra end-of-month payment (R)Optional, R0 to R2 000 000. Blank or 0 means no extra payment added.

Interest is charged monthly on the opening balance at your nominal annual rate divided by 12. The fee is added next, then the total month-end budget is paid. Actual lenders may charge interest daily or use different schedules.

How it's worked out

Each month starts with the unpaid balance. We multiply it by your nominal annual percentage divided by 12, rounding interest once to the nearest cent with half cents rounded up. We add the monthly account fee, then pay the smaller of your total budget and the amount due. The fee consumes the budget once; it isn't an extra payment on top.

A budget that doesn't exceed rounded interest plus the fee doesn't shrink the balance. We stop that scenario without a payoff forecast. Otherwise we repeat for at most 1 200 months (100 years). Anything beyond that is unresolved; partial amounts cover only those months.

All figures come from you. This is a monthly illustration, not a lender statement, settlement quote or verified contractual minimum. Rates and fees stay constant. Daily interest, payment dates, balloons, new spending, holidays, penalties and changing rates aren't modelled. No debt product, consolidation or legal debt-management decision is recommended.
