NerdWallet reviewed about 60 cash-back cards. To be considered, a card had to be widely available, offer elevated cash-back rates (in excess of 1%) in specific categories, and deliver a top rewards rate of:
• At least 5% for cards that limit how much spending is eligible for the top rate.
• At least 3% for cards with no limit on spending eligible for the top rate.
The cards we reviewed include products from NerdWallet partners, but this did not influence our selection of the winner.
