Balance over time

Stay Transfer

How the balance transfer calculator works

The tool runs two payoff plans side by side using the same monthly payment. In the first, you keep your balance on the current card at its existing APR. In the second, you move the balance to a new card, add the transfer fee, and pay the intro rate until the promotional window ends, then the standard rate after that. Comparing the total interest of each plan, including the fee, tells you whether the transfer is worth it.

The chart traces both balances over time. When the transfer line sits below the stay line and reaches zero sooner, the transfer is saving you money and months.

A quick example

You owe $6,000 at 22% APR and pay $300 a month. A new card offers 0% for 18 months with a 3% fee. The fee adds $180, but skipping interest for 18 months lets your payments crush the principal, often saving well over a thousand dollars compared with staying put.

Things to keep in mind

A transfer only helps if you stop adding new charges and pay it down before the intro rate expires. For consumer guidance on credit card offers, see the Consumer Financial Protection Bureau. You can also plan a payoff with our other free calculators.

Frequently asked questions

How does a balance transfer save money?

Moving a balance to a card with a 0% or low intro APR means more of each payment goes to principal instead of interest. As long as the interest you avoid is greater than the transfer fee, you come out ahead and clear the balance faster.

What is a balance transfer fee?

Most balance transfer cards charge a one-time fee, usually 3% to 5% of the amount you move. On a $6,000 transfer at 3% that is $180 added to your balance up front. This calculator includes the fee when comparing total cost.

What happens when the intro period ends?

Any balance left after the intro window starts accruing interest at the card's standard APR. To get the full benefit, aim to pay off the balance before the 0% period ends. This tool models the post-intro rate so you see the realistic outcome.

Will a balance transfer hurt my credit score?

Opening a new card causes a small temporary dip from the hard inquiry, but lowering your overall utilization can help over time. Avoid closing the old card right away and keep making on-time payments to protect your score.
