Extra payments:
Fixed total amount towards monthly payment?
If "Yes" is chosen, after a debt has been paid off, the money that was being paid to that specific debt will be distributed towards paying off remaining debts. If "No" is chosen, the monthly payment decreases as debts are paid off.
Assumptions
Use Debt Payoff Calculator for debt payoff planning when you need a clear estimate, transparent inputs, and a result you can review before taking the next step.
Worked example
When To Use Debt Payoff Calculator
- Start with a representative scenario in Debt Payoff Calculator so rates, dates, balances, or other key assumptions match the question you are comparing.
- Review whether the estimate matches the planning scenario before you use it for a budget, plan, or discussion.
Sample Input And Output Checks
- Start with inputs that match the real scenario, not only a rounded placeholder.
- Review APR, payment floor, payoff order, and total interest tradeoffs before trusting the output.
- Rerun the scenario when rates, balances, or monthly payment targets change.
About This Tool
About This Debt Payoff Calculator
This debt payoff calculator estimates how multiple debts could pay down under different repayment methods. Enter balances, interest rates, and minimum payments for up to 10 debts, then test extra monthly payments, annual lump sums, or one-time payments at specific months. The calculator compares the debt avalanche method (highest interest first) and debt snowball method (smallest balance first), showing estimated payoff timing and interest cost for each approach. Use the schedule as a planning reference, then verify balances, rates, fees, and payment rules against your lender statements before acting on the result.
Understanding Extra Payment Options and Fixed Total Payments
This debt payoff calculator lets you test extra payment assumptions against the debts you enter. Add a steady monthly extra payment, schedule an annual lump sum from a bonus or refund, or model a one-time payment for a specific month. The fixed total payment option controls what happens after one account reaches zero. When enabled, the amount that had been going to the paid-off debt rolls into the next priority debt, keeping the same total monthly outflow in the estimate. When disabled, the monthly outflow drops as accounts are eliminated, which may leave more room in a monthly budget but can extend the estimated payoff timeline. Use this option to compare repayment pace and cash-flow flexibility, then check lender rules for minimum payments, fees, promotional rates, and payment allocation. For revolving credit accounts, the Credit Card Payoff Calculator provides a card-focused estimate.
Debt Avalanche vs Debt Snowball Strategy Comparison
The debt avalanche method prioritizes debts with the highest interest rates first while making minimum payments on the others. In many estimates, that approach lowers interest cost when the interest rates and payment rules you entered stay unchanged. The debt snowball method targets the smallest balance first, which can make early account payoffs easier to see. The calculator displays both methods side by side with estimated payoff month, total interest, and account order, so you can compare the tradeoff instead of relying on one default answer. Review the schedule carefully if any debt has a promotional rate, deferred-interest rule, prepayment fee, or minimum-payment formula that changes over time. If you are considering combining accounts into one loan, use the Debt Consolidation Calculator to compare a separate consolidation scenario.
Using the Estimate Safely
Gather the current balance, APR, minimum payment, and payment due date for each debt before running the estimate. After the schedule is generated, compare it with your latest lender statements and update the numbers when balances, rates, fees, or required payments change. The principal-versus-interest chart can help explain why two repayment methods produce different totals, but it is still based on the assumptions you entered. For student loan scenarios that involve income-driven repayment, deferment, forgiveness programs, or government-servicer rules, use the specialized Student Loan Calculator and verify important decisions with the loan servicer or a qualified adviser.
What the Estimate Does Not Include
The calculator does not automatically model hardship programs, negotiated settlements, tax consequences, credit-score impact, variable-rate resets, late fees, or lender-specific payment allocation rules. It also assumes the extra payment amount is available for the full scenario unless you change the inputs. Treat the result as a planning comparison between repayment assumptions, not as a loan agreement or financial advice.
Common result checks
Questions about this tool
- What is the difference between debt snowball and debt avalanche?
- Debt snowball prioritizes the smallest balance first. Debt avalanche prioritizes the highest interest rate first. Avalanche often estimates lower interest cost, while snowball can make early account payoff easier to see.
- How do extra payments affect the payoff estimate?
- Extra payments reduce principal faster when they are applied consistently. The calculator lets you test monthly extra payments, annual lump sums, and one-time payments so you can compare payoff dates and estimated interest.
- What does fixed total payment mean?
- Fixed total payment keeps the same total monthly outflow after one debt is paid off by rolling that payment into the next priority debt. Turning it off reduces monthly outflow as debts disappear but can extend the timeline.
- Is this debt payoff calculator financial advice?
- No. It is an assumption-based planning estimate. Verify balances, rates, fees, minimum-payment rules, and payment allocation with each lender before making financial decisions.
