Actually, you need both
Both loan and credit card are good to start building credit. In order to build a credit history you need to use credit. The amount doesn’t matter. $10 or $1,000 builds the same credit. You need a stream of timely payments for a minimum of 24 months. With time your score will go up.
Both an installment loan and a credit card will do the job. However, choosing just one will build you a fair score. For a good score you’ll need both, because credit type diversity is actually good for your credit.
The thing is – you won’t qualify for a loan or credit card (unless you find a co-signer or can be added as an authorized user on your parents/wife card/loans)
This leave you with secured loans and credit cards. They are much easier to get (because you deposit a collateral), and build credit just the same.
A few more tips:
- Use the card for a few small purchases.
- Wait for the statement, and then pay it in full to avoid interest
- Avoid carrying a balance on your card. It doesn’t build credit, but very expensive (because of the interest
Good luck.
