How this calculator works +

This calculator compares two payoff plans: keeping the current credit card and moving the balance to a balance transfer offer. The current-card path applies monthly interest using your current APR, then subtracts your current monthly payment until the balance reaches zero.

The transfer path accounts for the transfer fee, applies the promo APR during the promotional period, then switches to the post-promo APR if a balance remains. The result compares total cost, payoff time, balance after promo, and the month when the interest saved first offsets the transfer fee.

This comparison assumes the full entered balance is transferred, no new purchases are made, and every payment arrives on time. New purchases and card-specific promotional conditions can change the real result.

Assumptions used

Interest accrues monthly using APR ÷ 12.
The current-card path uses the current APR and current monthly payment until payoff.
The balance-transfer path uses the promo APR for the promo period, then the post-promo APR after that.
The full balance entered is assumed to transfer. If the offer has a minimum fee, the calculator uses whichever is greater: the percentage-based fee or that minimum.
The transfer fee is either added to the new balance or treated as paid upfront, depending on the checkbox.
When the two monthly payments differ, the result reflects both the transfer terms and the payment change.
Break-even month is the first month when interest saved compared with the current card offsets the transfer fee.
No new purchases, late fees, annual fees, penalty APR changes, rewards, issuer-specific daily balance methods, or missed payments are included.

When a balance transfer helps—and when it doesn't

A lower promotional APR doesn't automatically make a transfer the better choice. The stronger plan is the one that lowers estimated total cost, recovers the transfer fee, and leaves a manageable balance when the promotional period ends.

Signs the transfer is helping

The fee is recovered early enough to create clear savings.
The transferred balance falls substantially before the regular APR begins.
Total cost and payoff time improve at a payment you can maintain.

Signs the current plan may be stronger

The fee isn't recovered or the estimated savings are small.
A large balance remains when the post-promotional APR starts.
The transfer costs more overall or extends the payoff timeline.

Pay close attention to the balance after the promo.

Any remaining balance begins accruing interest at the regular APR. A long 0% period helps most when the monthly payment reduces that balance before the promotional rate expires.
