Amex Blue Business Cards: 50K Points or $500 Back After $5K Spend

If you run a business—even a small side hustle—American Express just rolled out a pair of welcome offers that are worth a closer look. The Blue Business Plus and Blue Business Cash cards are both dangling 50,000 Membership Rewards points or $500 cash back after you spend $5,000 in the first three months. That's not the absolute highest we've ever seen on these cards, but it's well above the usual 10,000 to 25,000 points they typically offer. And since neither card charges an annual fee, the math gets pretty compelling.

What You're Actually Getting

Let's break down the two offers. The Blue Business Plus gives you 50,000 Membership Rewards points after you spend $5,000 in the first three months. Those points are transferable to Amex's airline and hotel partners, which is where the real value lives if you know how to use them.

The Blue Business Cash is the simpler option: $500 cash back after the same $5,000 spend. No point valuations to worry about—just straight cash credited to your statement.

Why the Blue Business Plus Stands Out

The Blue Business Plus has long been a favorite among points enthusiasts for one big reason: it earns 2x Membership Rewards on every purchase, up to $50,000 per calendar year. That's unusually generous for a no-annual-fee card, and it makes this a fantastic catch-all for spending that doesn't fall into a bonus category on another card.

But there's another angle that doesn't get enough attention. Because this card has no annual fee and earns Membership Rewards, it can serve as a kind of safety net for your points. If you ever decide to cancel a different Amex card that earns MR points, having the Blue Business Plus in your wallet keeps your entire points balance alive and transferable. That alone can be worth holding onto it long-term.

• 2x Membership Rewards on all eligible purchases (up to $50K/year)
• No annual fee
• Keeps your MR points active and transferable even if you close other Amex cards
• Points transfer to airline and hotel partners

The 12x Math on That First $5K

Here's a fun way to look at it: during those first three months, you're earning 2x on your $5,000 in spending, which gives you 10,000 points. Add the 50,000-point welcome bonus and you're sitting at 60,000 points total. That works out to 12x on every dollar you spent to hit the bonus. Even if you value Membership Rewards conservatively at around 1.5 cents each, that's a solid return on $5,000 of normal business expenses.

Who Should Consider These Offers

These cards make the most sense if you have a business—even a sole proprietorship or freelance gig—and you can comfortably put $5,000 on a card over three months without changing your normal spending habits. If you're already spending that much on office supplies, advertising, or everyday operating costs, this is essentially free money.

The Blue Business Plus is the better pick if you're into travel rewards and know how to squeeze value out of transfer partners. The Blue Business Cash is the better pick if you'd rather keep things simple and just take the cash.

A Few Things to Keep in Mind

First, neither card is ideal for international purchases. Both charge foreign transaction fees, so leave them at home when you travel abroad.

Second, the 2x or 2% earning rate only applies to the first $50,000 in purchases each calendar year. After that, it drops to 1x or 1%. For most small businesses, that cap won't be an issue, but it's worth knowing.

Third, American Express has a once-per-lifetime rule on welcome bonuses for most cards. If you've had either of these cards before, you likely won't qualify for the bonus again. And Amex also limits how many of their credit cards you can hold at once, so check your existing lineup before applying.

Finally, while this offer is strong compared to what these cards usually offer, it's not the absolute highest we've seen. If you're not in a rush, you could wait and see if a bigger bonus comes along. But if you have $5,000 in upcoming business expenses and want a no-annual-fee card that pulls its weight, this is a very reasonable time to jump in.

Bottom Line

• 50,000 Membership Rewards points or $500 cash back after $5,000 spend in 3 months
• Both cards have no annual fee
• Blue Business Plus earns 2x MR on all purchases up to $50K/year
• Blue Business Cash earns 2% cash back on all purchases up to $50K/year
• Neither card is good for international spending due to foreign transaction fees
• Amex once-per-lifetime bonus rule applies
