Korean auto-loan repayment and interest schedule

This English guide follows the Korean calculator logic and preserves the Korean rates, thresholds, vehicle classifications, and administrative assumptions used by the source page.

Principal, rate, term, and repayment method

The auto-loan calculator uses loan principal, annual interest rate, term in months, repayment method, and grace period. Equal-payment repayment uses the standard amortization formula, equal-principal repayment pays the same principal amount each month, and bullet repayment pays interest during the term with principal at maturity.

The default English example uses KRW 28 million principal, 5.9 percent annual rate, and 60 months, matching the Korean calculator style that focuses on the financed amount rather than the vehicle sticker price alone.

Grace-period months create interest-only months before principal repayment begins.
Total interest is summed from the generated monthly schedule.
Interest ratio is total interest divided by loan principal.

Repayment and rate comparisons

The result compares equal-payment, equal-principal, and bullet structures for the same principal, rate, term, and grace-period inputs. This shows why a lower first-month payment can still produce a higher total-interest burden.

The rate comparison tests the selected structure against annual rate offsets of minus 2, minus 1, base, plus 1, and plus 2 percentage points when those rates remain positive. That keeps the English result aligned with the Korean source function.
