Bank Statement Qualifying Income Estimator
A rough, illustrative look at how lenders typically calculate qualifying income from bank statements for self-employed borrowers. The actual number on your loan file depends on your specific business type, expense factor, lender, and program version.

This estimator is for illustrative and informational purposes only. The math here uses common 2026 industry assumptions — your actual qualifying income will be different. Bank statement programs vary widely between lenders and program versions. Key reasons your real number will differ:
- Expense factor varies by industry. A doctor's office is treated differently than a roofing contractor. Most lenders use 50% as a default for service businesses, but COGS-heavy industries (manufacturing, restaurants, retail, construction) often get 60–75% expense factors. Some lenders set the floor at 30%, others won't go below 50%.
- Personal vs. business statements behave differently. Most investors do NOT Use 100% of deposits even on personal statements — they apply ownership-percentage adjustments and add-back limitations. Don't assume "personal statements = full deposits."
- Transfers, refunds, loan proceeds, and one-time deposits get backed out — sometimes manually, sometimes with a CPA letter, sometimes denied entirely.
- Some lenders use 12 months, some use 24 months, and the 12-month option usually carries a rate adjustment or LTV reduction.
- P&L-only and 1099-only programs use completely different math than bank statement programs.
How lenders actually calculate bank statement income
The estimator above runs the standard simplified formula. Here's what actually happens during real underwriting, summarized from current 2026 NonQM guidelines we work with:
The expense factor is the biggest variable
The expense factor is our assumption about what portion of your deposits is consumed by business expenses before any cash reaches you. A service business with low overhead (a consulting practice, a solo attorney, a small medical practice) typically gets a 50% expense factor, meaning we assume half your deposits go to expenses and half is qualifying income. A construction company, restaurant, or wholesaler typically gets a 60-75% expense factor because COGS-heavy businesses have much higher real expenses.
Some programs let you use a CPA-prepared letter or P&L statement to document a lower expense ratio. If your CPA can attest that your business runs at a 30% expense ratio, certain lenders will use that number, which materially changes the qualifying income. Other lenders refuse the CPA-letter path entirely. Program-by-program.
Personal statements are not "use everything"
A common misconception is that personal bank statements let you count 100% of deposits as income. They don't. Most investor guidelines apply additional adjustments, ownership-share math when business income is deposited into a personal account, add-back limitations for non-recurring deposits, and program-specific haircuts to account for the fact that personal accounts mix business and personal cash flow. Personal statement programs also frequently come with lower max LTVs and stricter reserve requirements than business statement programs.
What gets backed out
- Transfers between your accounts (deposits that came from another account you own)
- Loan proceeds (lines of credit, term loans, SBA money)
- Tax refunds
- Insurance payouts
- Gifts
- One-time non-recurring deposits (sale of an asset, settlement, etc.)
Underwriters manually walk through each statement to identify these. The estimator above assumes you've already excluded them from "total deposits", if you haven't, your real qualifying income will be lower than the estimate.
12 vs. 24 months
24-month bank statement loans typically carry the best pricing. 12-month options exist and they're useful when you've had a recent income jump, but they almost always come with a rate adjuster (sometimes a quarter point or more) or an LTV reduction. The 24-month average smooths out seasonal fluctuations, which is why investors prefer it.
Alternative income paths (when bank statement doesn't fit)
- 1099-only programs, for independent contractors with a clean 1099 paper trail. Often simpler than bank statements.
- P&L statements, a CPA-prepared profit and loss often gets used in place of bank statements for certain business types.
- Asset utilization / asset qualifier, qualifying off liquid asset balance rather than monthly income. Useful for high-net-worth retirees, sold-business owners, or anyone with strong assets but variable income.
- DSCR loans, investment property only, qualifies on rental income vs. PITI, not your personal income at all.
Self-employed qualifying income: common questions
How do lenders calculate self-employed income?
We calculate it one of two ways. On a conventional loan we use the net taxable income from your tax returns, averaged over two years. On a bank statement loan we add up your deposits over 12 or 24 months, apply an expense factor of roughly 50% to 75%, and use what's left as your qualifying income. We pick whichever path qualifies you for the most house.
What income can I use to qualify when self-employed?
You can qualify on net taxable income from your tax returns, on bank deposits through a bank statement loan, on a CPA-prepared profit and loss statement, on 1099 income, or on liquid assets through an asset-utilization loan. We are the lender, so we run every path that fits your file and use the one that gives you the strongest number.
Do bank statement loans use gross or net deposits?
Neither, exactly. We start from your deposits, back out transfers, refunds, loan proceeds, and one-time non-business money, then apply an expense factor of about 50% to 75% to cover business costs. What remains is your qualifying income. We never count 100% of gross deposits, even on personal statements.
How accurate is a self-employed income estimate?
An estimate from this tool is directional only, not a quote or pre-approval. Your real number depends on your industry expense factor, your ownership percentage, which deposits an underwriter backs out, and the specific program. We confirm the accurate figure only after we review your actual statements, and it is usually lower than a quick estimate.
