Repayment Advice
- Prioritize full payment when possible to avoid high interest cost.
- Minimum payment is suitable for short cash gaps, while long-term cost is usually higher.
- For large spending, compare installment total fees with your monthly cash-flow pressure.
- Avoid overdue payment to prevent penalties and credit impact.
Bank Rule Notes (Estimated Model)
- This tool is for strategy estimation and may differ from your card issuer's final statement settlement.
- Revolving interest is simulated with monthly approximation (annual rate divided by 12).
- Minimum payment uses your ratio with a CNY 50 floor.
- Installment mode uses equal principal plus fixed monthly fee.
- Overdue penalties, penalty interest, cash-advance interest, and early settlement clauses are not included.
Use Cases
- Compare minimum payment and installment cost before statement due date.
- Evaluate cash-flow pressure and payoff timeline after large purchases.
- Estimate interest impact across repayment strategies in household budgeting.
FAQ
- Why can minimum payment fail to reduce debt? If payment is below current interest, principal does not decrease and balance may grow.
- Is installment always cheaper than minimum payment? Not always. Installments replace revolving interest with fees, so compare total payment and payoff speed.
- Will the result exactly match the bank statement? Not exactly. Use this tool for planning and confirm with your issuer statement and card agreement.
