Balance Transfer Calculator: Compare Interest, Fees, and Payoff Time

Updated
Many or all of the products here are from our partners that compensate us. It’s how we make money. But our editorial integrity ensures that our product ratings are not influenced by compensation.

Moving a credit card balance can lower interest costs or quietly make things worse. The difference comes down to timing, fees, and how fast you can pay the balance down.

This calculator is designed to answer one simple question: Does transferring your balance put more money back in your pocket, or not?

Enter a few details about your current card and the balance transfer offer you're considering. The calculator will estimate interest costs, fees, and payoff time so you can see whether the move actually helps.

Adjusted Plan With Balance Transfer Card

Based on the information entered, a balance transfer credit card would cost you more money in the long run. You may want to consider a personal loan instead.

Fee Disclosure: Some balance transfer credit cards may charge additional fees. These can include both annual fees and balance transfer fees. Check your card's terms and conditions for fee amounts. Your credit card will also have a balance transfer limit that restricts how much you can transfer. This limit should be listed in your cardholder agreement and will often be available by logging into your online account.

How this balance transfer calculator works

The calculator compares two scenarios:

  1. Keeping your balance on your current card
  2. Moving it to a balance transfer credit card

You'll see a side-by-side cost breakdown so you can decide whether a balance transfer actually helps or if it just shifts debt around.

Information you'll need to get started

You don't need exact penny-perfect numbers, but the closer you are, the more useful the results will be.

  • Total balance to move: This can be one card or several combined.
  • Interest rate on your current card: Look for the APR listed in your account or card terms.
  • Interest rate on the new card: If the card has a promotional balance transfer rate, enter that. Some cards charge a different rate for transfers than for purchases.
  • Transfer fee: Most cards charge a one-time fee, usually a percentage of the balance.
  • Monthly payment amount: The calculator assumes minimum payments unless you tell it otherwise. Increasing this number can dramatically change the outcome.

Once you see the results, try adjusting the payment amount or APR to test different scenarios.

How to read your results

After you enter your information, the calculator will estimate:

  • Total interest paid if you keep the balance where it is
  • Total cost after transferring (including fees)
  • How long it may take to pay off the balance
  • Whether the transfer produces real savings

If the "savings" are small, or negative, that's a signal to slow down before applying.

What a balance transfer actually does

A balance transfer shifts existing debt from one credit card to another. You're not paying a card with a card -- you're moving the balance to a new account that agrees to take it.

Some cards accept transfers automatically. Others don't allow them at all. Cards that do will clearly list balance transfer terms in their pricing details.

The appeal is straightforward: if the new card charges less interest than the old one, more of your payment goes toward the balance instead of interest.

Why timing matters more than the interest rate

Introductory 0% APR offers can be valuable, but only within their window.

Once the promotional period ends, any remaining balance begins accruing interest at the card's regular rate. If that rate is high, savings can disappear quickly.

This calculator helps you estimate whether your planned monthly payment is fast enough to beat the clock.

The hidden cost people overlook: Balance transfer fees

Almost all balance transfers come with a fee, typically between 3% and 5% of the amount moved.

That fee is added to your balance immediately. So even with a lower interest rate, you're starting slightly behind.

For smaller balances or short payoff timelines, the fee can cancel out the benefit. That's why it's included in the calculation.

How much you're allowed to move

Balance transfers are limited by your available credit on the new card.

A few things to keep in mind:

  • The transfer fee counts toward your limit
  • The limit applies to all transfers combined
  • You won't know the exact amount until approval

If your balance is larger than the approved limit, you may need multiple cards or a different strategy altogether.

Choosing a card after you run the numbers

Once you know what kind of terms you need, focus on:

  • Length of the promotional period
  • Size of the transfer fee
  • Interest rate after the promo ends
  • Annual fees (if any)

We track and review balance transfer credit cards based on introductory APR length, transfer fees, and ongoing rates so you can compare options side by side before applying. See our best balance transfer credit card picks today.

FAQs

  • Some cards advertise no-fee transfers for a limited time, but most charge a fee. Always check the fine print before assuming there's no cost.

  • Applying for a new card may cause a short-term dip due to a credit inquiry. Over time, reducing balances and lowering utilization can help offset that impact.
