When a balance transfer comparison is useful
Use this calculator when you have transfer terms to compare: promo APR, promo months, post-promo APR, transfer fee and monthly payment. If you only want to estimate payoff for one current card without transfer terms, start with the credit card payoff calculator.
Example: current card vs transfer terms
Suppose the current card has a 4,000 balance at 22% APR with a 250 monthly payment. A transfer offer might add a 3% fee, use 0% APR for 15 months and switch to 24% APR after the promo period. The comparison is easiest to read when the monthly payment stays the same across both scenarios.
For help choosing between the two tools, read Credit Card Payoff vs Balance Transfer.
How this balance transfer calculator works
The calculator estimates payoff for the current balance at the current APR/rate, then compares it with a transfer scenario that uses a promo rate, post-promo rate and transfer fee. Savings are shown after transfer fees.
Promo period and balance after promo
The promo APR/rate applies for the number of months entered. If a balance remains after that period, the calculator applies the post-promo APR/rate to the remaining balance.
Transfer fees
Transfer fees are counted once in the comparison. If the fee is added to the balance, it can also affect payoff time and interest because the transferred balance starts higher.
What this calculator does not include
This is a general estimate only. It does not compare live card offers, check eligibility, model credit-score effects, include missed-payment penalties, annual fees, issuer rules or new purchases.
Key terms and assumptionsCurrent card assumptions, promo-period math, transfer fees, break-even timing and limits of the comparison.
- Current card
- The current scenario pays the existing balance at the current APR/rate with the monthly payment entered.
- Balance transfer
- The transfer scenario uses the promo APR/rate during the promo period and the post-promo APR/rate after that.
- Transfer fee
- The transfer fee is counted once. If added to the balance, it also increases the starting transfer balance.
- Balance after promo
- Balance after promo is the estimated amount remaining when the promotional period ends.
- Break-even
- Break-even is the estimated month where interest savings recover the transfer fee.
- Region settings
- Region settings change defaults and currency formatting only. They do not convert exchange rates or create country-specific results.
- General estimate
- The result excludes eligibility, credit-score effects, penalties, annual fees, issuer-specific rules, new purchases and debt advice.

FAQs
What does a balance transfer calculator estimate?
It compares interest and fees for a transfer scenario against keeping the current balance.
Does a 0% promo rate mean the transfer is free?
Not always. Transfer fees and any balance left after the promo period can affect the result.
What if I do not pay off the balance during the promo period?
The calculator applies the post-promo APR/rate to the remaining balance after the promo period.
Does this include credit approval?
No. It does not check eligibility, credit-score effects, approval terms or card-specific rules.
Should I include new purchases?
This calculator focuses on the transferred balance only. New purchases are not included.
Why include a transfer fee?
A fee can reduce or eliminate the interest savings from a lower promo rate.
How is this different from the credit card payoff calculator?
This tool compares a transfer offer with the current card. The payoff calculator focuses on paying one card balance down.
Is this debt advice?
No. It is a general estimate based on the values entered, not financial, credit, tax, legal, accounting or debt counselling advice.
