  • Keep detailed records for tax purposes - you'll get a 1099-INT

How We Calculate Bank Bonus Value

Bank bonuses can be lucrative, but they come with opportunity costs. When you park money in a low-interest checking account to earn a bonus, you're giving up the interest you could have earned in a high-yield savings account.

Net Gain = Bonus + Bank Interest - HYSA Interest (Opportunity Cost) - Fees

The Effective APY shows what annual percentage yield your money effectively earned, including the bonus. This lets you compare the bonus to other investments on an apples-to-apples basis.

Effective APY = (Net Gain / Deposit) x (365 / Holding Days) x 100

The hourly rate estimates your return for the time spent opening the account, setting up direct deposits, and managing the process. We estimate about 2.5 hours of work for a typical bank bonus.
