Quick start
- Open the Credit Cards Payoff Calculator.
- Add the balances from the cards you want to group together.
- Enter a weighted average APR, giving more weight to the cards with bigger balances.
- Enter the regular monthly card payment and the extra amount you can keep adding.
- Calculate, then compare payoff months, total interest, total paid, and final payment before deciding whether you need a card-by-card plan.
Best uses
Start here if one of these sounds like your job. The examples below show which inputs matter most.
- Estimate payoff time after combining several card balances into one planning number.
- Compare the regular payment with an extra monthly payment.
- See total interest before choosing a debt payoff strategy.
- Check whether the total payment is strong enough to reduce principal.
What this calculator is for
Use the Credit Cards Payoff Calculator when you want one rough payoff picture for several cards. It works best when you know the combined balance, a weighted average APR, the regular payment, and the extra amount you can keep adding.
Use it when you want a quick combined view of several cards before deciding whether to build a true avalanche, snowball, consolidation, or hardship plan.
What to enter
Combined-card payoff estimates get shaky when one high-rate card is hidden inside a rough average. Keep balances, weighted APR, regular payment, and extra payment separate, then build a card-by-card plan if the stakes are high.
- Add the card balances together and enter the combined balance.
- Enter a weighted average APR if the cards have different rates, giving more weight to larger balances.
- Enter the regular monthly card payment and any extra monthly amount you can keep adding.
Example walkthrough
Try the starter example: $8,500 combined balance, 21.5% weighted APR, $350 regular monthly payment, and $100 extra. The estimate is 24 months, about $1,969.83 interest, about $10,469.83 total paid, and a final payment near $119.83.
- $8,500 at 21.5% weighted APR with a $350 regular payment plus $100 extra is treated as one combined balance.
- The estimate is 24 months, about $1,969.83 interest, about $10,469.83 total paid, and a final payment near $119.83.
Formula and steps
In plain language: The calculator treats the cards as one combined balance, converts weighted APR to a monthly rate, adds monthly interest, subtracts regular plus extra payment, and repeats until the combined balance reaches zero. $8,500 at 21.5% weighted APR with a $350 regular payment plus $100 extra estimates 24 months, about $1,969.83 interest, about $10,469.83 total paid, and a final payment near $119.83.
Start by combining balances, then turn the weighted APR into a simple monthly rate. Each month, the calculator adds estimated interest, subtracts the regular payment plus extra payment, and repeats until the combined balance reaches zero. CFPB explains that real card issuers often calculate interest daily and may split balances by APR, so this is a planning shortcut.
How to read the answer
Start with payoff months, then check total interest and total paid. If the number still hurts, test more extra payment or split the cards into a real avalanche plan so the highest APR is handled first.
- Payoff months estimates how long the combined balance may take to reach zero.
- Total interest shows the estimated interest cost during payoff.
- Total paid is balance plus estimated interest, and final payment may be lower than the normal monthly payment.
Common mistakes to avoid
Most bad combined-card payoff estimates come from using a lazy APR average, forgetting balance-transfer fees, keeping new spending alive, ignoring payment allocation, or treating a one-balance shortcut like a true card-by-card payoff strategy.
- Do not use this as a full avalanche or snowball plan.
- Do not forget separate APR tiers, payment allocation, balance-transfer fees, promotional rates, late fees, cash advances, deferred interest, and new purchases.
- Do not enter a payment that is lower than the monthly interest on the balance.
What to try next
A related tool can help after the combined-card estimate. The next question is usually one-card payoff detail, a plain debt payoff comparison, or whether consolidation changes the total cost.
- Use Credit Card Calculator for a single-card payoff.
- Use Debt Payoff Calculator for a plain fixed-balance payoff.
- Use Debt Consolidation Calculator to compare a new loan offer.
Sources and estimate notes
CFPB sources are useful here because combined-card payoff depends on APR, daily interest, grace periods, payment allocation, balance types, and card agreement terms. FTC debt guidance adds the plain warning that paying more than the minimum and stopping new spending can make the payoff real instead of just hopeful.
This calculator still stays simple. It does not read each statement, calculate average daily balance, split cards by APR, choose avalanche order, apply fees, model deferred interest, decide payment allocation, preserve a grace period, or replace card agreements.

FAQ in plain language
When should I use the Credit Cards Payoff Calculator?
Use it when you want to test the exact inputs on this page: Estimate payoff time after combining several card balances into one planning number. Compare the regular payment with an extra monthly payment. The result is a check against your assumptions, not proof that a lender, tax app, broker, platform, or provider will use the same number.
What do the main Credit Cards Payoff Calculator inputs mean?
Combined balance means the total balance across the cards you want to treat as one payoff plan. Weighted APR means an average APR that gives more weight to cards with bigger balances. Regular monthly payment means the total payment you can send every month before any extra payoff money. Extra monthly payment means extra money added on top of the regular payment to speed up the payoff.
Is this a snowball or avalanche payoff plan?
No. This combines your cards into one balance. A true snowball or avalanche plan needs each card balance, APR, minimum payment, and payoff order.
What is weighted APR?
Weighted APR is an average rate that gives more influence to larger card balances. It is useful for a quick combined estimate, but it is not the same as each card statement.
What is the Credit Cards Payoff Calculator doing with my numbers?
In plain language: The calculator treats the cards as one combined balance, converts weighted APR to a monthly rate, adds monthly interest, subtracts regular plus extra payment, and repeats until the combined balance reaches zero. $8,500 at 21.5% weighted APR with a $350 regular payment plus $100 extra estimates 24 months, about $1,969.83 interest, about $10,469.83 total paid, and a final payment near $119.83.
How should I read the Credit Cards Payoff Calculator answer?
Start with payoff months, then check total interest and total paid. If interest still looks high, test a bigger payment or separate the cards into an avalanche plan.
What does this estimate leave out?
This is simplified combined-balance payoff math. It does not model average daily balance billing, separate APR tiers, payment allocation, cash advances, balance-transfer terms, deferred interest, fees, penalty APRs, minimum-payment changes, grace-period rules, or new purchases. Use card statements, card agreements, payoff tools from the issuer, or a nonprofit credit counselor for exact daily interest, payment allocation, hardship plans, and account-specific rules.
