The best two- and three-card combinations

One card is simple. Two let each category go to the card that pays most on it. On an illustrative household's $2,205 a month, the best pair — American Express Blue Business Plus and American Express Gold Card — earns $1,141 a year after fees, against $1,058 for the best single card, American Express Blue Business Plus. A third card adds another $122.

The short version

Start with a card that pays well on everything, then add one for your biggest category.
On this household's spending, Blue Business Plus and Gold Card is the best pair.
Add a third card only if it pays a bonus somewhere the first two don't — and more than its fee.
Use your own spending in the next-card calculator.

Yearly figures are priced on an illustrative household spending $2,205 a month on a card — an assumption, not a statistic. The assumption, in full. Every combination of cards whose rates have been checked is tried, each card valued for what it adds over the others, caps honoured and rotating categories not credited. A card whose category you choose is given the one you spend most on. Credits, perks and sign-up bonuses are not priced.

Why the answer depends on you

A combination is only as good as the spending it was priced on. Somebody who spends more on travel than this household, or less on groceries, gets a different set — which is what the next-card calculator is for: enter your own spending and the cards you already hold, and it ranks what to add.
