How Is Income Calculated on a Bank Statement Loan?

On a bank statement loan, the lender adds up the deposits into your accounts over 12 or 24 months, removes transfers and one-time deposits, averages the rest into a monthly figure, then counts a percentage of that as your qualifying income. There are no tax returns and no pay stubs involved. The whole point is to measure the cash actually flowing through your accounts, which for many self-employed borrowers is far higher than what their tax returns show. For a broader look at the programs, see our alternative documentation loans page.

Step one: total the deposits

The lender pulls 12 or 24 months of statements and totals your deposits. A 24-month review often unlocks better terms, because it shows a longer, steadier track record. A 12-month review can help if you recently started a business or just had a strong year.

Step two: strip out what does not count

Not every dollar counts. The lender removes transfers between your own accounts, so you are not double-counting the same money. One-time deposits like a tax refund, a loan, or the sale of an asset also come out, because they are not recurring income. What is left is your real, repeatable deposit flow.

Step three: apply the expense factor

This is where personal and business statements differ. On personal bank statements, lenders often count close to 100 percent of the deposits, since your personal account is assumed to hold your take-home money. On business bank statements, they apply an expense factor, commonly around 50 percent, to account for the cost of running the business. So $20,000 a month in business deposits might qualify as roughly $10,000 in income.

The CPA letter that can raise your income

If your actual business expenses are lower than the standard 50 percent, a letter from your CPA documenting your real expense ratio can raise your qualifying income, sometimes a lot. A consultant with light overhead might get an expense factor closer to 25 percent instead of 50, which nearly doubles the income the lender can use. If your expenses are genuinely low, this one document can move your whole approval.

What else the lender weighs

Deposit consistency matters as much as the total. Steady monthly inflows underwrite better than a few big spikes. Your credit score and down payment then set your rate and loan-to-value. Once you know your monthly deposits, our affordability calculator gives you a rough sense of the loan that income supports, and your debt-to-income ratio still factors into the final approval.
