Debt Payoff Calculator
Build a payoff plan from real balances, APRs, minimum payments, and one extra monthly payment, then compare debt avalanche and snowball paths.
Debt plan
Build the payoff list
Start with the debts you want this plan to attack. Use current balances, APRs, and required minimum payments so the payoff order reflects the month you are actually managing.
Pay the highest APR first to usually reduce total interest.

Extra money after minimum payments are covered.

Strategy comparison
Compare the math and the momentum
Avalanche usually lowers interest. Snowball can create earlier wins. The better plan is the one that fits both the numbers and the behavior needed to keep paying.
Alternate
Snowball
2 years, 4 months and $4,170 of interest
Baseline
Minimums only
6 years, 3 months and $9,245 of interest
The selected strategy saves about $982 versus the alternate strategy at the same payment level.
How to use this debt calculator
Use the calculator to separate payoff math from payoff behavior. The goal is a plan that lowers debt and still feels realistic enough to keep.
Avalanche
Usually strongest when high-rate debt is the main problem and you can stay motivated without an early payoff win.
Snowball
Usually strongest when early wins help you stay engaged and keep the plan moving month after month.
Minimums only
Useful as a baseline, but usually not the plan if you have extra money available for debt reduction.
1
List every balance once
Use the balances, APRs, and minimum payments that are actually due. The payoff path is only useful when the debt list is current.
2
Choose where extra money goes first
Avalanche sends extra payment to the highest APR. Snowball sends it to the smallest balance. Both still keep every minimum payment current.
3
Pick the plan you can keep
The lowest-interest plan matters, but consistency matters too. Use the comparison to choose a payoff order that can survive a normal month.
About this tool
What this helps you do
This calculator turns a scattered debt list into a payoff model, then shows how strategy choice and extra monthly payment change the path.
How to interpret results
Treat the output as a planning estimate. Real payoff timing can change with variable rates, late fees, skipped payments, new borrowing, or lender-specific terms.
Where it helps most
It is most useful when you know your balances and want to compare interest savings, first-win timing, total payoff time, and monthly payment effort.
Limitations
This tool is educational only. It is not legal advice, credit counseling, a debt-management plan, or a negotiated payoff agreement with a lender or collector.
