Short answer: checks that come with a credit card account borrow against your card, not your bank account. Before you use one, read the table printed on the front of the check page: it shows which rate applies (for example, the purchase or cash advance rate, or a promotional rate and when it ends), the APR, any transaction fee, and whether there is a grace period. If you do not plan to use the checks, keep them safe or shred them. This is general information, not legal or financial advice.

What the rules require on the check page

Regulation Z calls these “checks that can be used to access a credit card account”. If they are sent more than 30 days after the account-opening disclosures, or sooner on different finance charge terms, the creditor “shall disclose on the front of the page containing the checks the following terms in the form of a table” (12 CFR 1026.9(b)(3)(i), eCFR, text up to date as of October 28, 2026, read October 30, 2026):

  • If a promotional rate applies: the promotional rate and how long it lasts; “The type of rate that will apply (such as whether the purchase or cash advance rate applies) after the promotional rate expires” and that APR; and any date by which you must use the checks to get the promotional rate (1026.9(b)(3)(i)(A)).
  • If no promotional rate applies: “The type of rate that will apply to the checks and the applicable annual percentage rate” (1026.9(b)(3)(i)(B)).
  • Any transaction fees for the checks (1026.9(b)(3)(i)(C)).
  • Whether there is a grace period. The row is headed “How to Avoid Paying Interest on Check Transactions” when there is one, and “Paying Interest” when there is not (1026.9(b)(3)(i)(D)).

The figures must be accurate when the checks are mailed or delivered, and a variable APR counts as accurate “if it was in effect within 60 days” of that date. If a rate is variable, the issuer must also say the rate may vary and how it is set (1026.9(b)(3)(ii) and (iii)). Checks sent within 30 days of account opening on the same terms need no new disclosures (1026.9(b)(1)).

Which rate applies

The rule does not set the rate for the checks. It requires the table to name the rate type, so read it each time: a check can be treated like a cash advance, like a purchase, or under a promotional offer. If the table shows the cash advance rate with no grace period, see credit card cash advance vs personal loan for how that cost adds up.

When a promotional rate ends

Regulation Z lets a card issuer raise a rate “upon the expiration of a specified period of six months or longer”, provided that before the period starts it disclosed in writing “the length of the period and the annual percentage rate, fee, or charge that would apply after expiration of the period” (12 CFR 1026.55(b)(1), eCFR, read October 30, 2026). That is the rate the check table shows for after the promotion. Divide what you borrow by the number of months in the promotion to see the payment that clears it in time.

The grace period on your other purchases

A CFPB bulletin warns card issuers that offers of a promotional APR on transactions that “include, but are not limited to, convenience checks” risk being deceptive if they do not make clear that a consumer who keeps using the card for purchases “will lose the grace period on the new purchases if the consumer does not pay the entire statement balance, including the amount subject to the promotional APR, by the payment due date” (CFPB Bulletin 2014-02, September 3, 2014, read October 30, 2026). This bulletin is from 2014 and may be out of date; your card agreement and the check table are the place to check. For how lost grace periods lead to interest after you pay, see credit card trailing interest, and for promotional transfers in general, see balance transfer card vs personal loan.

Questions to ask the issuer

  • Is this check treated as a purchase, a cash advance or a balance transfer on my account?
  • What is the APR now, and what will it be after any promotional period ends? On what date does it end?
  • What is the transaction fee, and is it a percentage with a minimum dollar amount?
  • Will I lose the grace period on my purchases if I carry the check balance?
  • How do I stop the checks from being sent, and what should I do if they are lost or stolen?

A $2,000 check, only for the math

This example is only for the math, not an offer any issuer makes. The 3% fee and the 12-month promotion are example figures, not sourced rates. A 3% fee on a $2,000 check is $2,000 x 3% = $60.00. To pay $2,000 off within a 12-month promotion takes $2,000 / 12 = about $166.67 a month, plus any interest on other balances.

If the check instead carries a standard card rate and you pay it over 24 months, here is $2,000 at the Federal Reserve’s August 2026 averages: 22.36% for credit card plans and 11.90% APR for 24-month personal loans (G.19). The table leaves out the check fee.

OptionMonthly paymentInterestTotal paid
Card at 22.36%, 24 months$104.11$498.64$2,498.64
Personal loan at 11.90%, 24 months$94.05$257.20$2,257.20

$104.11 x 24 = $2,498.64, and $94.05 x 24 = $2,257.20. Your rate depends on your credit and the lender, and fees raise the cost. Compare the APR, the fees and the total paid. See credit card minimum payment vs personal loan.

Checklist

  • Read the table on the front of the check page before you write a check.
  • Note the rate type, the APR, the fee and any promotion end date.
  • Check whether there is a grace period on the checks.
  • Plan the monthly payment that clears any promotional balance in time.
  • Shred checks you will not use.
