The Balance Transfer Fee Isn't the Cost. Every Month You Wait Is.A transfer fee is prepaid interest, and it almost always pays for itself within a couple of months.

Frequently Asked Questions

Everything you need to know.

What does an example Minimum Payment Trap Calculator calculation look like?
Using this calculator's own default assumptions, a card balance of $6,000, apr of 24.99% and minimum payment percent of 2% produces an estimated approx months at minimum of Never (pay more) and estimated minimum payment of $120. Enter your own numbers above to see how it changes for your situation.
Why does paying extra save so much interest?
Interest compounds on your remaining balance each month, so the longer you carry a balance, the more total interest accrues. Paying extra reduces the principal faster, which means less balance for interest to compound on in future months. This creates a compounding effect in reverse: the sooner you pay down the balance, the fewer months of interest you face.
How is the minimum payment calculated?
Card issuers typically calculate minimum payment as a percentage of your current balance, but they also set a floor so the payment doesn't drop below a certain amount on very small balances. This calculator factors in both the percentage method and the floor to show your realistic minimum payment and how long payoff would take at that rate.
Is the Minimum Payment Trap Calculator free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Minimum Payment Trap Calculator affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?

How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (cards) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?

Where can I see the ranking methodology?

Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

Credit card minimums are designed to keep you paying for years while interest compounds on your remaining balance. Even small extra payments dramatically accelerate payoff and reduce the total interest you owe, but most cardholders don't realize how much difference a modest boost makes. This calculator reveals the true cost of minimum payments versus the savings from paying more.

How to Use It

  1. 1Enter your current credit card balance.
  2. 2Input your card's annual percentage rate (APR).
  3. 3Enter the percentage your card issuer uses to calculate the minimum payment.
  4. 4Input your card's minimum payment floor (the lowest payment required even on very small balances).
  5. 5Specify any extra amount you plan to pay each month beyond the minimum.
  6. 6Review the estimated minimum payment, months to payoff at minimum, months to payoff with extra payments, and total interest saved.
