American Express Cash Magnet Review

American Express just launched a cash back card that earns 1.5% on everything to compete with cards like the Chase Freedom Unlimited and the Bank of America Travel Rewards card. 

The Amex Cash Magnet is a credit card, not a charge card. If you don't qualify for the bonus, the new welcome bonus qualification tool should pop up

American Express Cash Magnet

  • Annual fee: $0
  • Signup bonus: $150 after you spend $1,000 within the first three months of account opening
    • Earn $150 when you spend an additional $6,500
  • 1.5% Unlimited cash back on everything

$300 Signup Bonus

Although the signup bonus is advertised as $300, you'll need to spend $7,500 within the first year to earn $300.

  • Tranche 1: $150 / $1,000 = 15% Return On Spend (ROS)
  • Tranche 2: $150 / $6,500 = 2.3% ROS
  • Total (Blended): $300 / $7,500 = 4% ROS

The American Express Cash Magnet is a mediocre card in my book because there are better alternative cards out there that offer a $150 signup bonus after $500 in spend within the first three months of account opening. 

The Amex Cash Magnet also earns cash back only, and not Membership Rewards points.
