Prepayment Fee by Remaining Term
Explore a contract assumption where the fee falls with remaining time. Products differ in exemption periods and day-count rules, so this worksheet does not retrieve a lender’s actual payoff charge.

How to use this tool
Enter the amount being prepaid, fee percentage, reference term and remaining months. The remaining/reference ratio is capped at one, and month-based inputs do not represent daily differences.
Results and examples
Fee equals repayment × rate × the capped remaining-term fraction. Accrued interest and the loan balance itself are separate, so do not confuse this fee with a lender’s total payoff amount.
Worked example
KRW 10 million at 1% with 12 of 36 months remaining gives about KRW 33,333.
Limitations
- Annual exemptions, elapsed-period waivers and product-specific clauses are not applied.
- Actual days, rounding and same-day interest can differ by contract.
