You can redeem your Earnin Cash Back Rewards balance by opening the Earnin app and tapping on “Cash Back Rewards”. If you have a current balance, you will see a green “Redeem” button that also specifies the amount that can be redeemed. Tap on this and follow the steps to confirm your transaction.
Your Cash Back Rewards balance will be sent to the checking account linked to your Earnin account. There is no limit on how much you can redeem.
