Before you start
For U.S. open-end consumer credit cards not secured by a home. This is an allocation check, not an instruction to miss another payment. Disputed or secured balances and accepted allocation requests can require a different analysis.
Split one payment into two parts
Find the minimum on the statement for the payment cycle you are checking. Then find the amount actually credited. For one payment that satisfies that minimum, extra payment = payment − minimum, with zero extra when the payment does not exceed the minimum.
Regulation Z § 1026.53 governs the extra portion, not the minimum’s allocation. Ask the issuer how the minimum was distributed. If you made several payments in one cycle, ask which amounts already satisfied the minimum; do not subtract the full minimum separately from every payment. A refund is not automatically a required payment.
Map the balances by their applicable APR
Make one row for each balance category: purchases, cash advances and transfers, plus separate promotional purchases when needed. Copy the amount, APR and promotion end date. The CFPB explains separate APR categories and payment allocation. Do not assign the whole card the purchase APR when another category has a different rate.
Under the general rule, extra dollars go first to the highest APR, then the next highest after that balance is exhausted. For balances with the same APR, the rule generally does not prescribe which goes first. The issuer may use rates and balances from a consistent date between the previous cycle’s closing date and the payment crediting date. Check the rule’s rate-date and equal-rate interpretations.
Identify the deferred-interest exception
A deferred-interest offer can charge interest from the purchase date if its payoff condition is missed. During the offer, that balance is treated as 0% for allocation, so higher-rate balances generally receive the extra payment first. In the last two billing cycles before expiration, extra payment must go first to the deferred-interest balance, unless an accepted consumer request directs allocation under the special rule. See the deferred-interest allocation rule.
Billing cycles are not simply the last 60 calendar days. If the offer expires before the payment due date in that cycle, that cycle is not one of the two. Ask which cycles and payments qualify. A true 0% introductory APR without retroactive interest does not receive this special deadline priority. An issuer may accept an allocation request for a deferred-interest balance but need not do so. CFPB: request allocation and check the promotion deadline.
Compare the expected split with what happened
Save your starting category balances and the credited payment date. Ask for a category-by-category explanation of the minimum and extra portions. A statement’s balance subject to an interest rate can be a calculation figure, such as an average daily balance; do not automatically treat it as the exact remaining principal after payment.
New purchases, interest, credits and different snapshot dates can obscure the reduction. Compare like dates and separate those movements before alleging an error. For disputed balances, or balances secured by property, ask how the applicable special rule affected allocation. Regulation Z also addresses these situations. Keep the explanation with your statement.
Use the answer to plan the next payment
If the promotion barely changed, find out why before increasing an amount you cannot sustain. Ask: “How much of my next payment will reach this specific promotion, and do you accept a request to direct the extra portion there?” Record whether the request was accepted and any timing or written-form requirement.
Budget from the amount that reaches the target balance, not merely the total you send. Stop adding new charges if feasible while you clarify the split. Check the following statement to see whether the accepted request was carried out. This worksheet records questions; it does not direct the issuer or guarantee a promotion will be repaid.
Fictional example: a $500 payment does not reduce the promotion by $500
Assume one payment of $500 and a $50 required minimum. Before allocation, balances are $1,000 at a true 0% introductory APR, $400 of purchases at 24% and $100 of cash advances at 30%. Assume the issuer applies the entire minimum to the 0% balance. No new charges, fees or interest are added during this allocation snapshot; there are no disputed or secured balances.
The extra portion is $450. It clears the $100 cash-advance balance first and sends $350 to purchases. The 0% promotion falls by only $50, the purchase balance ends at $50, and total debt falls from $1,500 to $1,000. This illustrates one assumed minimum policy, not every issuer’s policy.
| Balance | Starting amount | Payment applied | Remaining |
|---|---|---|---|
| True 0% promotion | $1,000 | $50 minimum | $950 |
| Purchases at 24% | $400 | $350 extra | $50 |
| Cash advance at 30% | $100 | $100 extra | $0 |
Before you finish
- Separate the credited payment from the required minimum.
- List every balance category, APR and promotion end date.
- Confirm how the issuer allocates the minimum and dates the rate snapshot.
- Check whether a deferred-interest exception or accepted request applies.
- Reconcile posted allocation before setting the next target payment.
Trace one payment across your balances
Use neutral category names and one payment cycle. Do not enter account numbers. Record the issuer’s answer separately from your own estimate.
Optional notes stay in this page's memory. This worksheet does not send or save your entries. Do not enter account numbers, passwords, Social Security numbers, or other private information. Downloading or printing creates a copy you control.
Ask the issuer to fill the missing allocation details, then compare the next posted payment with that explanation.
Illustrate how an extra payment could be allocated
Use three balance categories on one card. First enter the issuer's confirmed allocation of the required minimum, or enter your own hypothetical split. The model allocates only the amount above that minimum by descending APR.
Illustration only: assumes these three categories cover the balance, the minimum split you entered applies, and there is no deferred-interest exception or other special allocation rule. It does not calculate interest or predict the issuer's actual allocation. Equal APRs use category order only for this illustration. For an unused category, enter 0 in all three fields: balance, APR, and minimum share.
Use USD amounts from 0 to 1,000,000,000, with a decimal point and at most two decimal places. No commas, currency symbols, or scientific notation. APRs: 0–100%, at most two decimal places.
Model unavailable for this situation. Check the contract and ask the issuer how payments are allocated, especially during the last two billing cycles before deferred interest expires. The rule and timing can depend on the promotion; this model cannot resolve them.
Questions you may have
Can I always choose which purchase my payment pays off?
No. The general rule concerns APR categories. Special consumer-request provisions exist for deferred-interest or secured balances, but the issuer may decline the request if it otherwise follows the applicable allocation rule. Regulation Z: consumer requests.
Will the last-two-cycle rule protect my ordinary 0% balance transfer?
Not merely because its promotional APR is ending. The special priority is for a deferred-interest or similar program with contingent accrued interest. Confirm the actual offer type. Regulation Z: distinction between programs.
What if I cannot see the payment split in the app?
Ask the issuer for the starting category balances, minimum allocation, extra allocation and dates used. Record what remains unconfirmed instead of treating an estimated split as a verified account result.
