TransUnion, one of the major credit bureaus, says that there’s “no single, exact deadline or formula” for credit score updates. The updates largely depend on when creditors report account activity, and whether they report it to each of the three credit bureaus.
TransUnion does offer an estimate. It said that consumers can count on creditors reporting account activity ever 30 to 45 days. Experian points out that creditors rarely report updates to the bureaus simultaneously. For example, Experian may register new information a week before Equifax.
There isn’t a set day of the month when the account updates come through. It’s entirely up to the creditor. Your score can change “within days — even within hours — as different accounts supply information about your credit activity,” according to the bureau.
However, The Balance, notes that credit card issuers often update account information on your account statement closing date—the last day of your billing cycle.
