Credit Card Tune-Up features a free credit card reward calculator for finding the best rewards cards for your spending profile. Most people are missing out on $100's per year.
The Credit Card Tune-Up calculator makes all of that easy. Just plug in how much you spend each month in the box on the right, press the Recalculate button, and you'll be presented with a list of recommended cards sorted from best to worst by your expected first-year annual reward (minus any annual card fee). All reward types (i.e. miles, points, cashback) are converted into dollars for an easy apples-to-apples comparison.
