Their first credit card

Credit history is the one financial asset you cannot buy later. A twenty-two-year-old with four years of on-time payments behind them rents an apartment and insures a car on visibly better terms than someone starting from zero the week they graduate. The setup takes about ten minutes.

Why it matters at eighteen

Lenders score how long someone has been paying people back on time, and the length of that record counts. There is no way to shorten the wait later. Starting at eighteen means those years already exist by the time a lease or a car loan depends on them.

Two ways in

Most students cannot qualify for a good card on their own income. There are two ordinary routes.

Add them as an authorized user on your card. You keep the account and the liability. They get a card in their name, and the account's history usually reports on their credit file, so they inherit your record instead of starting empty. You can set their limit low, you see every transaction, and you can remove them in an afternoon. Check first that your issuer reports authorized users to the credit bureaus, because a few do not.

A student card or a secured card in their own name. Student cards are underwritten for people with no history. A secured card holds a deposit that becomes the credit line, so approval is close to automatic. Either one builds a file in their name, which being an authorized user does not fully do. Many families do both.

The three rules

Pay the statement in full, on time, every month. A card paid in full charges no interest, which is why the interest rate barely matters for a student and a carried balance is the only thing that does. Set up autopay for the full statement balance before the first purchase.

Keep the balance small against the limit. The share of the limit in use gets reported and moves the score. A low limit is easy to run most of the way up on one textbook order, which reads as strain even when it clears days later.

Do not apply casually. Every application marks the file. One is nothing. Four in a semester, because a store offered a discount at the register each time, is a pattern.

What to skip

Rewards, for now. A percentage back on coffee and textbooks is not worth choosing a card around, and chasing it leads to annual fees a student's spending cannot repay. At any age the question is whether the rewards on what you actually buy exceed the fee.

Store cards at the register. Small discount, high rate, another application for a card they use twice.

Anything sold as a credit builder with a monthly subscription. An authorized-user slot and a secured card do the same work free.

If a term abroad is coming

Most everyday cards add a percentage to purchases made in another currency. It is easy to miss and it accumulates over a semester, so it is worth having one card without that fee before they fly. There is more on the planning in co-ops, internships and study abroad.

What a parent actually does

Set up the autopay together, on their laptop, so they have done it once. Agree out loud what the card is for, because "emergencies" means something different at nineteen. Read the first two or three statements together, then stop. The aim is a young adult who handles this without you.
