Flex Elite Card Waitlist Opens: Up to 5% Cash Back, But There's a Catch

Flex, a private banking platform for businesses, is now taking waitlist sign-ups for its first personal credit card, the Flex Elite. The headline pitch is straightforward: earn up to 5% cash back on all purchases with no annual fee. But as with most generous-sounding offers, the details matter a lot. Here's what you need to know before you join the list.

How the cash back tiers work

The Flex Elite doesn't have a single flat cash back rate. Instead, your earnings depend on how much money you keep on deposit with Flex. If you hold $1 million or more, you get 5% back on purchases. Keep at least $250,000 and you'll earn 4%. And with any balance—even $0—you still get 3% back.

That's a unique structure. Most cards with tiered rewards base them on spending, not deposits. Here, the card is essentially a perk for parking serious cash with Flex. For everyday spenders, the 3% rate is still solid, especially with no annual fee.

• 5% back with $1M+ in deposits
• 4% back with $250k+ in deposits
• 3% back with any deposit amount, including $0

The monthly cap you should know about

There's a subtle limit on how much you can earn at the higher rates. You only get the 4% or 5% rate on purchases up to your assigned credit limit each month. If you spend more than that limit within a billing cycle—say, by making payments and continuing to spend—those extra purchases drop to 3% cash back.

So if you're planning to use the card for business expenses or large purchases, keep an eye on your credit limit. The card may not be as rewarding as it first appears for heavy spenders.

• 4% and 5% rates apply only up to your monthly credit limit
• Purchases above that limit earn 3%
• Cycling your limit can reduce your overall cash back

What doesn't earn cash back

Flex has published a fairly extensive list of exclusions. As of October 12, 2026, you won't earn rewards on cash advances, ATM withdrawals, balance transfers, person-to-person payments, gambling or betting transactions, wire transfers, money orders, checks, prepaid cards, or disputed charges. Interest and fees also don't earn cash back.

That's a long list, but it's not unusual for a premium rewards card. Just don't expect to earn 3% on everything—especially not on cash-like transactions.

• Cash advances and ATM withdrawals
• Balance transfers
• Person-to-person transactions
• Gambling, lottery, and sports betting
• Wire transfers, money orders, and checks
• Prepaid cards and cash equivalents
• Interest charges and fees
• Disputed or fraudulent charges

The deposit side: is it worth it?

Flex currently pays 2.47% on deposits, which is decent but not competitive with the best high-yield savings accounts. If you're chasing the top cash back rate, you'd need to hold $1 million with Flex—money that could likely earn more elsewhere.

But Flex is hinting at new high-yield account options in the future. If those materialize, the combination of a top-tier deposit rate and up to 5% cash back could become more compelling. For now, the deposit rate alone isn't a reason to sign up.

• Flex deposit APY: 2.47%
• Lower than many competing high-yield accounts
• Flex is teasing higher-yield deposit products

Who is this card actually for?

The Flex Elite seems designed for people who already have a substantial relationship with Flex—or who are willing to move significant assets there. If you have $250,000 or more to deposit, the 4% or 5% cash back could be very attractive, especially with no annual fee.

For everyone else, the 3% base rate is still competitive, but you'll need to weigh it against other no-fee cards that offer similar or better returns without the deposit requirement. And keep in mind that Flex is a newer player—it raised $60 million in Series B funding, so it has capital, but it doesn't have the track record of a major bank.

• Best for those with $250k+ to deposit
• 3% base rate is solid for no annual fee
• Consider Flex's startup status and deposit safety

Bottom Line

• Flex Elite offers up to 5% cash back with no annual fee, but the top rate requires $1M in deposits.
• The 4% and 5% rates apply only up to your credit limit each month; above that, you earn 3%.
• Many transaction types are excluded from earning cash back, including cash advances, balance transfers, and gambling.
• Flex deposits currently pay 2.47%, which is not competitive with top high-yield accounts.
• The card is best suited for those who already plan to hold significant deposits with Flex.
