Credit cards

First cards: what to look for at the start

The short answer

The point of a first card is a clean reporting history, not rewards. A low limit with no annual fee, paid in full every cycle, does more for a file than a larger limit carrying a balance.1

The reason a first card matters beyond the first year is that length of credit history is itself an input. An account opened early and kept open in good standing keeps contributing for as long as it exists.

What a first card is actually building

Two of the inputs that carry the most weight — payment history and length of history — are both built in years, not in months. A card opened at twenty and paid on time is still helping at thirty, which is why closing it later is usually a mistake.

What a first card contributes to a file, and what it does not.

Input	Built by	Timeframe
Payment history	Paying on time, every cycle	Immediate, and cumulative
Length of history	Keeping the account open	Years
Utilisation	What is reported at statement close	Each cycle
Credit mix	Different types of account over time	Years
New inquiries	Applications made	Short window

Statement balance versus current balance

This distinction decides whether interest is charged. The statement balance is what the issuer reported at closing; the current balance may be different. Paying the statement balance in full inside the grace period means no interest on purchases, and it also lowers what gets reported.

Being added as an authorised user

Being added to an existing account can build history without a separate application, and on some accounts it is reported as if it were the person's own. It also ties the two files together: payment behaviour on the primary account appears on both histories.

Where the rules differ

Protections for young consumers, marketing restrictions on campuses and disclosure requirements sit in federal consumer protection law and, in some states, in stricter state rules. Where the two differ, the stricter rule generally applies.
