APR vs rewards
Can rewards outrun credit card interest? $351
A $3,000 balance at 22.36% APR with a $300 monthly payment creates about $351 of interest in year one.
Bottom line
Interest drag should be solved before optimizing rewards.
Rewards are usually worth one to a few percent of spend. Revolving APR can run above twenty percent annually on carried balances.
Next move
Compare payoff speed, balance-transfer fees, and APR resets.
A balance transfer can help only when the fee and payoff timeline beat the interest you would otherwise pay.
