Earnings Credit Rate (ECR) Calculator
Find the average balance your business checking account needs to fully offset its monthly fees at your bank-quoted ECR, and see the after-tax value of sweeping any balance above that into a taxable commercial sweep or money market fund.
Quick answer: Find the average balance your business checking account needs to fully offset its monthly fees at your bank-quoted ECR, and the after-tax value of sweeping any balance above that into a taxable commercial sweep or money market fund. Enter Average collected balance, Monthly account fees, ECR rate, and Alternative sweep rate to personalize the estimate. It returns Balance needed to offset fees, Excess balance earning nothing, and After-tax value of sweeping the excess so you can compare the impact before choosing a next step. Use it to compare payment, APR, total cost, credit impact, and lender or card tradeoffs.
Your account needs about $243,333 on deposit to fully offset $150/month in fees at a 0.75% ECR.
Above that, $0 is earning nothing beyond fee coverage — sweeping it could be worth about $0 more per year after tax.

Why This Matters
An Earnings Credit Rate isn't a public rate — it's negotiated per relationship and only offsets fees, it doesn't pay out in cash. Many business owners keep far more in a 0%-interest checking account than their ECR program can actually use, forfeiting real after-tax yield on the excess.
