Who it is worth it for

If secondary rental car insurance is the reason you are looking at the American Express Platinum Card, the Capital One Quicksilver lists it too, with no annual fee — $895 a year less. 7 cards here carry it for a lower fee in all. What the difference buys is the rest of the American Express Platinum Card: its rewards and the other benefits below. Compare the two summaries before deciding they are the same cover.

On rewards alone, the illustrative household spending $2,205 a month (the assumption, in full) earns about $625 a year on the American Express Platinum Card, or −$270 once its $895 fee is paid. So the rewards leave $270 of the fee for the card's credits and benefits — this one among them — to make up. It is worth it for somebody who would use enough of them, at face value, to cover that gap; credits are not priced here because they are worth their face only if you would have spent the money anyway.
