Using the comparison

Compare cards FAQ

Can I compare more than two cards on my phone?

Yes. Select up to four cards. On a phone, two cards appear side by side. Tap the left or right card menu to show another selected card; the rest stay in your comparison.

How do I add or replace a card?

Open Change cards, choose two to four cards and apply your selection. The same control stays beside the section menu as you scroll through the table.

Which plan do the cashback figures describe?

Entry-plan and top-plan rewards have separate rows, with the plan name shown for each. A headline maximum can apply to a bonus category rather than every purchase. The info icons beside the figures show their qualifying terms.

What is the difference between the cashback caps?

A cashback cap limits the rewards you earn. A full-rate spend cap limits the purchases earning a particular rate; a lower rate may apply afterwards. A redemption cap limits how much you can redeem. These are separate rows because they measure different things.

Does Not disclosed mean a fee is zero?

No. It means we do not have a published figure for that item. Confirmed zero fees appear as 0% or $0. Tap an info icon for plan, asset or regional conditions attached to a published fee.

Do partner offers influence the scores?

No. Scores and rankings follow our published methodology. Partner links, signup offers and commissions never change those calculations.
