The review in three checks
Check first: Match the promotion to the transaction
Inspect closely: Add every upfront fee
Resolve before acting: Schedule payoff before the advertised end
Open the review: Define the eligible balance
Confirm whether the promotion covers purchases, balance transfers or both; each can have a different duration. Record any transfer deadline, eligible creditors and maximum amount. Do not assume a balance can be moved from another account with the same issuer, or that a transfer requested on the last day will complete in time.
Inspect the details: Price the promotion from day one
Add transfer or transaction fees to the starting balance and keep annual fees separate. Divide the full promotional balance by the number of available payment months, using a date one statement earlier as the internal finish line. Compare that amount with reliable monthly cash flow before opening the account.
Resolve the gaps: Model the imperfect case
Calculate the balance remaining after one reduced payment and apply the disclosed ongoing APR. Review late-payment and promotional terms without assuming a single mistake has one universal consequence. Continue paying the old creditor until the transfer posts, and avoid adding purchases when their interest treatment would complicate the payoff.
Complete the review without skipping evidence
- Which transactions and dates qualify?
- What fee is added at the start?
- What ongoing APR applies to a remainder?
- Can the payoff survive one disrupted month?
Leave an audit trail
Save the offer, agreement and transfer confirmation. Record the promotional end date, internal payoff date and scheduled amount. Check every statement for the promotional balance, required minimum and unexpected fee, then preserve proof when the balance reaches zero.
Primary source: CFPB credit card resources.
Translate the promotion into four dates
Record the account-opening date, transfer or purchase deadline, final promotional cycle and date the ongoing APR begins. “Twelve months” is less useful than the exact statement on which promotional treatment ends. Put a payoff target one cycle earlier to leave room for timing errors.
Separate purchases from transferred balances
Confirm which transactions qualify, the transfer fee, how payments are allocated and whether purchases receive a grace period while a transferred balance remains. A zero promotional APR does not mean every transaction has no cost.
- Calculate the starting balance after fees.
- Divide by usable payoff months, not the advertised count alone.
- Model the remainder at the disclosed ongoing APR.
- Check what a late payment can change.
For example, a $4,000 balance plus a 3% transfer fee starts at $4,120. Over eleven usable payments, the simple target is about $374.55 a month. This illustration excludes new transactions and uses no offer-specific terms.
Define the exit before opening
Write what happens if the planned monthly payment becomes unaffordable: which expense changes, which non-card resource is available and whether the transfer should be smaller. An offer should not be opened when the only fallback is another promotional account that has not been approved.
Resolve the neighboring checks: Carry unresolved document questions into the next review instead of treating a blank as a favorable answer. Test this choice against the same repayment behavior and annual spending used for the balance-transfer break-even point, then carry the result into the full cash-advance cost before comparing issuer offers. See the credit card borrowing-cost guides for the complete sequence.
Complete and document the review
Check each item against the current document and keep unresolved points visible.
Finish the checklist with evidence
A promotional APR is useful only when it applies to the transaction you plan, the transfer or purchase is completed on time, fees are counted and the balance can be repaid before the ongoing rate applies.
