Overview

How the Balance Transfer Calculator Works

Balance transfer offers look like free money — until the transfer fee gets baked into the new balance and the promotional APR expires. This calculator simulates both paths month by month so you can see, in real dollars, whether the transfer actually beats just staying put.

Formula

The Math Behind the Calculator

Current path: standard month-by-month payoff at the current APR with your monthly payment. Transfer path: new balance = old balance × (1 + fee%); apply intro APR for the promo period, then post-intro APR until paid off. Savings = (Current total paid) − (Transfer total paid, including fee).

Example

A Worked Example

$8,000 at 24% APR, paying $300/month → payoff in ~36 months, total interest ≈ $2,700. Transfer with 3% fee, 0% for 15 months, then 19% APR, same $300/month → fee $240, payoff in ~28 months, total interest ≈ $400. Net savings ≈ $2,060.

How to use

How to Use the Balance Transfer Calculator

  1. 1Enter your current balance, APR, and the monthly payment you're making now.
  2. 2Enter the transfer offer details: fee %, intro APR (often 0%), intro length (months), and the post-intro APR.
  3. 3Keep the same monthly payment on both paths for an apples-to-apples comparison.
  4. 4Check whether the balance can be paid off within the intro period — that's when transfers shine.
Interpretation

What the Results Mean

  • Savings is the dollar difference between staying put and transferring.
  • Paid off during intro means the offer worked perfectly — you avoided post-intro interest entirely.
  • If savings is small or negative, the fee outweighs the rate cut at your payment level.
Avoid

Common Mistakes to Avoid

  • Transferring and then making only the new minimum payment — you'll hit the post-intro rate with most of the balance still owed.
  • Charging new purchases on the transfer card; many offers apply payments to the lowest-rate balance first, leaving new purchases compounding at full APR.
  • Forgetting that opening a new card temporarily dings your credit score.

FAQ

Frequently Asked Questions

Is a balance transfer worth it?+

Usually yes if you can pay the balance off within the intro period at the monthly payment you've planned. The fee is a one-time cost; ongoing interest is the bigger lever.

What APR is the fee equivalent to?+

A 3% fee on a balance paid off in 12 months is roughly equivalent to a 3% APR — far better than 20%+ on your current card, even before counting the 0% intro savings.

Can I transfer between cards from the same issuer?+

Usually no — issuers only allow transfers from cards at other banks. Check the offer's terms.
