Learn moreWhen a transfer is worth it
A balance transfer is worth it when the interest you avoid during the 0% window is larger than the transfer fee (typically 3–5%). The biggest wins come from paying aggressively so the balance is gone — or nearly gone — before the intro rate expires.
How it’s calculated & sources
We compute interest on your current card if you stay, then model the new card: the fee is added to the balance, the intro rate applies for the intro months, and any leftover balance reverts to the current APR. Net savings = interest avoided − interest still paid − the fee.
Benchmark: net interest saved over the 0% intro window, after the transfer fee. Typical fees are 3–5% (CFPB).

Worked example
Moving $6,000 from a 22% card to an 18-month 0% offer with a 3% ($180) fee, paying $350/month, clears it inside the window and saves well over $1,000 in interest net of the fee.
Frequently asked questions
Is the transfer fee worth it?
Usually yes if you carry the balance for several months — the avoided interest dwarfs a 3–5% fee. The calculator shows the net figure.
What happens when the 0% ends?
Any remaining balance starts accruing at the card’s regular APR. Aim to finish before then.
