Value per $1 uses the same point values as Discover Value: cash back at face value, points at Perqt's value for each program. Rates that apply all the time are shown, with caps and booking sites named; limited-time, spend-threshold and pick-one bonuses are in each card's full review. Annual fees and welcome offers are not counted here.

Wondering which one is right for your wallet?

Spec sheets can't tell you which card actually earns more for the way you spend. Perqt connects to your wallet, runs the math against your real transactions, and tells you which of these two — or another card entirely — gives you the biggest annual uplift.
