Card loan and revolving guide

This English guide translates the Korean card loan and revolving calculator. The calculator calls calculateCardLoan, simulateRevolving, and compareMethods with Korean 2026 card-loan and revolving rate assumptions.

Card loan repayment schedule

The card-loan model supports equal payment, equal principal, and bullet repayment. It calculates first monthly payment, average monthly payment, total interest, total payment, effective burden rate, and a month-by-month schedule of principal, interest, payment, and balance.

The Korean constants preserve the 2026 card-loan average rate of 14.0%, a card-loan rate range of 8.0% to 19.9%, a legal maximum-rate context of 20.0%, and a card-loan term range from 2 to 60 months.

Revolving fee accumulation

The revolving model uses carried balance, payment ratio, annual fee rate, and optional monthly spending. It reports payoff months, total fee, total payment, effective burden rate, steady-state balance, and steady-state monthly fee.

The Korean constants preserve a 2026 revolving average fee rate of 17.0%, a fee-rate range of 5.0% to 19.95%, minimum payment ratio of 10%, and maximum payment ratio of 100%. Low payment ratios can keep the balance from falling when monthly spending continues.

Lump sum versus card loan versus revolving

The comparison module evaluates lump-sum repayment, card loan, and revolving for the same amount. It reports total cost, total payment, months required, cheapest method, revolving extra cost versus card loan, and a recommendation.

The purpose is to show why revolving can look convenient but become expensive when the payment ratio is low or spending continues. Card loan installment repayment can be more predictable because principal amortization is explicit.

Korea-specific assumptions

Actual card-loan and revolving rates depend on card company, credit grade, current delinquency status, promotional terms, and legal maximum-rate rules. Use the Korean calculator for comparison, not borrowing advice.
