What Is the 0% Intro APR Payoff Calculator?
Many credit cards offer a promotional 0% introductory APR for a set number of months on purchases or balance transfers. During this window no interest accrues, so every dollar you pay goes straight to the principal. This calculator tells you the fixed monthly payment you need to make to fully clear your balance before the promotional period ends and the regular (often high) APR kicks in.
How to Use It
Enter the balance you want to pay off and the length of your 0% intro APR period in months. The calculator divides the balance evenly across those months, showing the steady payment that guarantees a zero balance by the deadline. Aim to set up an automatic payment for at least this amount.
The Formula Explained
The math is intentionally simple because the interest rate is 0%:
$$\text{Monthly Payment} = \frac{\text{Balance (\$)}}{\text{Intro Period (months)}}$$
Since no interest is added during the introductory period, you only need to spread the principal evenly. If you pay less than this amount, a remaining balance will be charged the full standard APR once the promo ends.
Worked Example
Suppose you transferred a $5,000 balance to a card with a 0% intro APR for 12 months. Your required payment is $$\$5{,}000 \div 12 = \$416.67 \text{ per month}$$ Pay that amount every month and you reach a $0 balance exactly when the promotion expires — paying nothing in interest.
FAQ
What happens if I don't pay it off in time? Any remaining balance starts accruing interest at the card's regular APR, which can be 20% or more. Some cards even charge deferred interest retroactively, so finishing on time matters.
Does this include a balance transfer fee? No. Many transfers charge a 3–5% fee added to your balance. Add that fee to your balance before entering it for a more accurate payment.
Should I pay more than the calculated amount? Paying more builds a buffer and clears the debt early, which is wise in case of an unexpected month where you can't pay the full amount.
