- 独立内容 / Unique value
- Makes the model boundary and stop conditions explicit, with links to detailed methodology and trust pages
- Source scope
- Answers are grounded in the production calculator and linked primary sources. English examples use US consumer-credit sources where stated; local lender terms always control.

- FAQ answers cannot replace a current lender statement or professional advice
These answers explain how the calculator should be used, what it does not do, and why the estimates should be checked against real lender terms.
Is debt snowball or debt avalanche better?
Debt snowball is often easier to stick with because it pays the smallest balance first and creates quick wins. Debt avalanche usually saves more interest because it pays the highest APR first. The better plan is the one you can follow consistently.
Does this calculator upload my debt data?
No. Calculations, exports, and share links are handled in your browser. Balances, APRs, minimum payments, and schedules are not sent to a server.
What should I enter as extra monthly payment?
Enter the amount you can reliably pay after covering all minimum payments. Start with a sustainable number so the plan does not compete with essential expenses.
Is this financial advice?
No. Results are educational planning estimates. Real loans may have daily interest, fees, promotional rates, or prepayment rules.
Why can the estimate differ from my credit-card statement?
The calculator uses APR divided by 12 once per simulated month. Many card issuers use daily or average-daily balances, different billing-cycle lengths, fees, grace periods, and payment-allocation rules.
What happens if a minimum payment is lower than the estimated interest?
The calculator shows a warning because the balance may grow before extra money is assigned. If the plan cannot reduce balances within the model limit, it returns a not-payable result instead of inventing a payoff date.
Does the minimum payment decrease as my balance falls?
Not automatically. The model keeps the minimum you entered constant until that debt is paid. Update the input when a new statement changes the required amount.
How are lump-sum payments applied?
A lump sum is applied in its selected month after required payments and follows the chosen strategy. If it pays off one target, the unused amount continues to the next eligible debt.
Can the calculator model a promotional APR ending?
It does not change APR automatically on a future date. Run separate before-and-after scenarios or update the APR when the promotion ends, and use the card agreement as the source of truth.
What does a not-payable result mean?
It means the entered payments and assumptions did not produce a safe payoff schedule within 1,200 months, or the numbers exceeded the model's safe range. It is a warning to review inputs and real options, not a legal conclusion.
How does custom priority work?
Every minimum is still paid first. Extra money then follows the debt order you selected, and any debts missing from an imported legacy order are appended safely.
Is an exact scenario safe to post publicly?
No. Exact-plan links encode the balances and settings needed to restore the scenario. Keep them private. Public social buttons share only the canonical calculator URL, not the encoded plan.
Methodology note
The calculator uses your balances, APRs, minimum payments, and extra monthly budget to compare simplified repayment strategies. It pays minimums first and then applies the extra budget by selected priority.
The estimate uses monthly compounding approximation. Real accounts may use daily interest, charge fees, apply promotional APRs, offer hardship programs, or enforce prepayment rules that change outcomes.
Privacy boundary
Calculations run in your browser. The site does not require an account, does not upload your debt data, and does not store your plan on a server.
If you create a share link, treat it as sensitive because the scenario data needed to recreate the plan can be encoded in the URL.
Advice boundary
The FAQ and calculator are educational only and are not financial advice, legal advice, tax advice, credit repair advice, or lender recommendations.
For decisions involving settlement, bankruptcy, hardship programs, taxes, credit disputes, or lender negotiations, consult a qualified professional.
How to read an estimate
Use the payoff date and interest estimate as planning signals. Then compare them with current statements, APR disclosures, minimum payment rules, and any promotional terms.
If a real account changes rate or fee terms, update the inputs and recalculate before relying on the plan.
Methodology and limitations
FAQ answers share the same model boundary as the calculator: minimum payments first, extra budget by priority, monthly compounding approximation, and rounded display values.
Daily interest, fees, promotional APRs, hardship programs, and prepayment rules can change real-world outcomes.
- Daily interest can make real payoff timing differ from this monthly approximation.
- Fees, late charges, annual fees, balance transfer fees, and promotional APR expirations can change the result.
- Hardship programs, settlement offers, deferment, forbearance, and lender-specific prepayment rules are outside this model.
- Check your statements and lender terms before acting on any repayment plan.
