Build a payoff calendar before your credit card promotion ends

1. Identify what ends and what you still owe

Copy the exact offer wording, expiration date, rate during the offer and rate afterward. A monthly payment due date can differ from a promotion’s expiration. If the statement lists multiple promotional purchases, give each one its own balance and end date.

A true 0% APR offer and deferred interest have different consequences: an unpaid deferred-interest balance can trigger interest dating back to the purchase; a true 0% offer does not retroactively charge interest for its 0% period. A reduced-rate promotion can accrue interest now. Check the conditions too. The CFPB explains these differences.

2. Choose receipt dates, then schedule backward

Ask the issuer which payment method, cutoff and time zone apply to the promotional payoff. For ordinary due-date payments, reasonable cutoffs generally cannot be earlier than 5 p.m. at the designated receipt location; qualifying in-person branch payments follow branch-closing rules. This does not establish a universal promotional-expiration cutoff. Regulation Z § 1026.10 sets payment-crediting rules.

Keep the initiation date, expected receipt date and visible posting date separate. A conforming payment generally receives credit as of receipt, although it may appear later. A bank’s bill-pay instruction is not necessarily receipt by the issuer. Confirm delivery time with the provider. Do not assume a weekend or holiday extends a promotion.

Choose an earlier final target that leaves time to correct a returned payment or allocation mistake. A buffer is your planning choice, not a guaranteed processing period. If you cannot confirm how quickly a method works, do not build the plan around its fastest possible outcome.

3. Count the payments you can actually fund

List future dates on which money will be available after essentials and required payments. Count only payments expected to reach the issuer by your target. Four calendar months may contain only three affordable payment opportunities. Keep every monthly minimum and due date on the calendar, even if you intend to finish early.

For a confirmed 0% balance with no new charges, divide the remaining promotional amount, including any unpaid fee assigned to it, by the remaining payments. Round planned installments up to cents and adjust the last one. With positive interest, new fees or other balances, simple division understates or misallocates what may be needed; request an updated amount from the issuer.

4. Track the promotional balance, not just total payments

Extra money sent to a mixed-balance card does not necessarily all reduce the promotion. Amounts above the minimum generally go to the highest APR first; deferred-interest promotions have special allocation rules near expiration. The minimum’s allocation can differ. Read Regulation Z § 1026.53 and ask how your payment will be applied.

After each payment, compare the actual promotional reduction with the planned reduction. Record fees separately and avoid counting a transfer fee twice if it is already in the displayed balance. Keep purchases off this calendar unless you explicitly include them. A pending refund is not a completed payment or confirmed reduction.

5. Confirm the last payment and handle a shortfall

Before the final target, obtain the current promotional payoff amount and confirm whether pending charges or interest affect it. After payment, check receipt credit, posting and the promotion’s remaining balance. Save the confirmation and inspect the next statement. A calculator reaching zero does not confirm the real account is paid.

If the calendar leaves a gap, ask the issuer promptly about available arrangements and their costs. Do not assume it will extend the offer. The CFPB recommends early contact when a card payment is unaffordable. Replace only terms that the issuer actually confirms, then rebuild the remaining calendar.

Fictional calendar: three payments, including a transfer fee

On 2026-09-15, the only balance is $1,440 plus a $36 unpaid transfer fee already included in the displayed promotional total of $1,476. The contract gives both amounts 0% APR through 2026-12-20. There are no new charges, other fees or interest; all other promotional conditions remain met. September’s minimum is already satisfied. The fictional minimum is $35 on October 20, November 20 and December 20.

Three payments of $492 total $1,476. The dates below are chosen planning assumptions, not a promise about any bank. Each payment is assumed received and visibly posted on its target date, fully applied to this sole balance and not returned. The final target is six calendar days before expiration.

Before you finish

• Identify the offer type, eligible balance and exact expiration.
• Separate the minimum-payment dates from the promotional target.
• Include unpaid fees once and any applicable interest.
• Confirm delivery, cutoff and allocation with the issuer.
• Replace estimated reductions with actual posted results.
• Verify zero promotional balance and review the next statement.
