The short answer

Start with the job the card needs to do, compare the full pricing table—not only the welcome offer—and make a repayment plan before charging. Rewards rarely compensate for interest on a carried balance.

Quick answers

Common questions, answered directly

What should I compare before applying for a credit card?

Compare the purchase APR, annual fee, penalty terms, foreign-transaction fee, rewards rules and any promotional-rate end date. Approval odds and the effect of an application also depend on your credit profile.

Does carrying a balance help build credit?

You generally do not need to carry an interest-bearing balance to build credit. Payment history and reported utilization matter; paying the statement balance by the due date can avoid purchase interest when a grace period applies.

Are rewards worth more than credit card interest?

Usually not when you carry a balance. A rewards rate can be outweighed quickly by interest, so compare the dollar value of benefits with fees and expected financing costs.
