Rewards minus fees, twelve payments a year. A negative number means a card costs you money.
When a card is worth it
The fee usually beats the reward, except when it unlocks a sign-up bonus. Example: someone who already puts $1,000 a month on a card could pay 1 mortgage payment of $2,000 by card for about $61 in fees, reach the Chase Sapphire Preferred bonus, and keep about $594 after fees and the annual fee. Then switch back to the bank account. Run your own numbers.
A debit card payment earns no meaningful rewards, so it is only a convenience.
Watch out for
Mortgage payments mailed to the wrong state P.O. box can be returned, causing late fees and delinquent credit reporting.
