How to use this tool
Enter the financed principal, number of months and annual interest rate. First establish whether a quoted charge is interest on the remaining balance or a flat fee, as those are not interchangeable inputs.
Results and examples
KRW 1.2 million over twelve interest-free payments gives KRW 100,000 per month. At a positive rate, the level-payment formula charges interest on the remaining balance and total payments exceed principal.
Limitations
- Issuer billing dates, equal-principal fee methods and promotional conditions can differ.
- Late charges, merchant fees and per-period won rounding are excluded.
