I have one cash back card from BofA that had been at 7% until recently, still under 10%, that they gave me when I temporarily had a high checking account balance from the proceeds of a home sale. So for every three months of interest I pay on the card, they pay me back a little more than one month's worth. <shrug>My current APR on my cards are:
Bank of America Visa Traveler Rewards 19.24%
Capital One Mastercard 18.65%
Citibank Mastercard 24.49% (talk about usury)
Chase Visa 14.99%
Apple Card Mastercard 18.24% (started off at 15.99% when I first got it in March of 2021).
Should mention my current FICO score runs around 810, give or take a few points up or down each month. But I pay off every bill in full every month for the last twenty years (what the credit card companies call a 'deadbeat' because I don't pay them interest).
Still, I remember the days before 2007-9 when Congress passed the "Consumer protection act" Remember that one? Most interest rates on credit cards were 5-8%, because they made their money on all those idiots buying hot tubs with no way to pay for it. After that bill was passed, never saw a rate below 12% again.
In fair disclosure, I only have "reward" cards, which most institutions expect to be paid off every month in exchange for the "generous" rewards
For decades I was a "deadbeat" paying off the balance every month until a confluence of events - some beyond my control - occurred over a short period of time. I just figure sometimes it's better to use the bank's money and pay the piper instead of laying out my savings that I might need for something unexpected. Or for retirement.
