The verdict
On a typical year of business spending, the American Express Business Green Rewards Card earns about $450 a year in rewards and the Citi Double Cash® about $900, valuing every point at a flat 1 cent. The American Express Business Green Rewards Card charges $95, which you clear through its rewards and perks. The Citi Double Cash® has no annual fee, so its rewards are all profit. Counting rewards, fees, and any credits, the Citi Double Cash® delivers more total value, about $545 a year more for a typical spender, mostly because it earns more where you spend most, on everything else and advertising. Both earn transferable points rather than flat cash, so the deciding factor is whose transfer partners reach the airlines and hotels you would actually book. On the sign-up bonus, the Citi Double Cash® currently has the larger welcome offer. A welcome bonus is a one-time event, so weigh it apart from the ongoing rewards.
Pick the Citi Double Cash® if your spending leans toward advertising, shipping, office supplies.
