Are Rewards Cards Worth It for Low Spenders?
The annual fee is the deciding factor
Rewards scale with spending, so a low spender earns less in absolute dollars, which means a fixed annual fee eats a bigger share of the rewards. A $95 fee is easy to justify on heavy spending but hard to justify on light spending. The break-even math is the same idea as in are annual fees worth it: the less you spend, the less a fee card makes sense.
Stick to no-fee flat cash back
A no-annual-fee flat cash back card is ideal for a low spender, because there is no fee to overcome and every purchase earns the same simple rate. You capture a clean 1.5 to 2 percent on all spending with zero break-even, which is the bulk of the value a rewards card can offer. See the options in best cash back cards.
Welcome bonuses still help
Even light spenders can benefit from a welcome bonus, as long as the minimum spend is one you can hit through normal purchases without stretching. Do not chase a bonus that requires spending you cannot comfortably reach. Run your real spending through the rewards calculator to see which no-fee cards, and which achievable bonuses, earn the most for a modest budget.
