NEW YORK (Credit.com) -- Credit card rewards programs are so varied, it can be difficult to determine which product should earn prime placement in your wallet. Here’s how to figure out which one you should be favoring.

Interest rate/fee structures are reasonable

Rewards cards tend to carry higher annual percentage rates and fee structures than no-frills products, essentially so issuers can subsidize the miles or points. But a card you’re going to use every day needs to be cost-effective. There are plenty of quality rewards cards that don’t charge an annual fee, including popular cash back cards, like the JPMorgan Chase Chase Freedom or Capital One Financial Cash cards.

In terms of interest rates, be wary of favoring a card whose interest rate is nearing 25%. APR scales on rewards tend to fluctuate between 14% and 22%, but there are a few that offer lower rates to consumers with great credit scores. Discover Financial Services, for instance, offers APRs between 10.99% and 19.99% on its popular More Card. If you do feel strongly about a certain card and the issuer awards you an APR on the higher end of their scale, you can always call them up after establishing a payment history to see if they will lower it.

Rewards are concentrated in your most common spending category

A great go-to rewards card is going to be the one that obviously earns you the most points, miles or cash back. You can easily increase earning potential by opting for a card that features maximum return in a category you already spend a lot on. For instance, commuters might want to opt for a great gas rewards card, like the Pentagon Federal Platinum Cash Back card, while foodies might want to opt for a card like the Chase Sapphire Preferred, which offers two points back per dollar spent at restaurants.
