How it works

How lenders calculate income from bank statements

Unlike W-2 borrowers, self-employed income is calculated by averaging your deposits and applying an expense ratio — not by looking at your tax return AGI.

Income calculation formula
Avg monthly deposits
×
(100% − expense ratio)

Qualifying income
Example: $12,000/mo deposits × (100% − 50%) = $6,000/mo qualifying income

Which expense ratio applies to your business?

Ratio
Business type
Examples
Income from $10K/mo
40%
Low-expense business
Software consultant, freelance writer, online business, professional services
$10K deposits → $6,000 qualifying income
50%
Standard (lender default)
General contractor, real estate agent, most service businesses
$10K deposits → $5,000 qualifying income
60%
High-expense business
Restaurant, retail store, staffing agency, trucking
$10K deposits → $4,000 qualifying income
Tip: If you have a CPA letter documenting your actual expense ratio is lower than the lender's default, you can often negotiate a more favorable ratio — directly increasing your qualifying income and maximum loan amount.

DTI limits

How DTI limits your loan amount

36%
Very conservative
Some portfolio lenders and banks use 36% as a strict cap. Harder to qualify but better rates.
43%
Standard non-QM
Most bank statement lenders default to 43% DTI. The calculator default. Most borrowers target this.
50%
Flexible programs
Available with compensating factors: 12+ months reserves, 720+ credit score, low LTV.
55%
Max stretch
A few non-QM lenders allow 55% for strong borrowers. Rare and comes with higher rates.

Before you apply

Analyze your bank statements before the lender does

Before submitting to a lender, run your own bank statement analysis here. You'll see exactly what a lender sees — your average monthly deposits, any red flags (large unexplained transfers, NSF fees, declining balances), and whether your income supports the loan amount you need.

  • See your real average monthly deposit figure
  • Identify unexplained large deposits before lender asks
  • Spot NSF fees or overdrafts that hurt qualification

Bank statement loan calculator FAQ

How does a bank statement loan calculator work?+−
A bank statement loan calculator applies the same income calculation lenders use: take your average monthly deposits, subtract the expense ratio (typically 50%), and the result is your qualifying income. Then it runs that income through a standard DTI (debt-to-income) calculation to determine how large a mortgage payment you can support — and converts that to a maximum loan amount based on current non-QM rates.
What is the expense ratio in a bank statement loan?+−
The expense ratio is the percentage of your deposits that lenders assume are business expenses rather than income. The most common default is 50% — so $10,000/month in deposits becomes $5,000/month of qualifying income. Some lenders use 40% for low-expense businesses (consultants, online businesses) or 60% for high-expense businesses (restaurants, retail). A CPA letter confirming your actual expense ratio can get you a better number.
What DTI ratio do bank statement loan lenders use?+−
Most non-QM bank statement lenders allow up to 43–50% DTI (debt-to-income ratio). Some programs go to 55% for borrowers with strong compensating factors (large reserves, high credit score, low LTV). Conservative lenders use 43% as a hard cap. The calculator defaults to 43% but you can adjust it to match your target lender's requirements.
Should I use personal or business bank statements?+−
Either works, but the rules differ. For personal statements, lenders typically use 100% of deposits (minus expense ratio). For business statements, lenders look at business deposits and apply an expense ratio. If your business deposits are much larger than your personal deposits, business statements often yield a higher qualifying income. Some lenders will blend both. The calculator uses a single deposit figure — enter whichever account gives you the best income picture.
How many months of deposits should I average for the calculator?+−
Most lenders require 12 or 24 months of statements. Use the lower average if your income has been growing (it gives a conservative estimate). If your income fluctuates seasonally, 24 months smooths out the highs and lows. For the most accurate estimate, average the deposits across however many months your target lender will require.
What interest rate does the calculator use?+−
The calculator uses estimated rate ranges based on your LTV (loan-to-value ratio). Non-QM bank statement loans currently range from approximately 7–10.5% depending on LTV, credit score, and lender. The calculator uses the midpoint of the range for payment calculations. Actual rates vary — get quotes from at least 3 lenders to find your real rate.
Why is my calculated loan amount lower than I expected?+−
The most common reasons: (1) The 50% expense ratio cuts qualifying income in half — if you have a CPA letter showing lower actual expenses, use 40% instead. (2) Other monthly debts (car loans, credit cards) reduce how much is left for housing. (3) Property tax and insurance eat into your DTI before the mortgage payment. (4) Try increasing your deposit average, reducing other debts, or adjusting the LTV and DTI sliders.
Can I use this calculator for a refinance as well as a purchase?+−
Yes — the loan amount output applies to both purchases and refinances. For a purchase, divide the loan amount by your LTV% to find the maximum purchase price. For a refinance, the loan amount is your maximum new loan balance. Note that cash-out refinances are typically capped at lower LTVs (75–80%) and may have stricter income requirements.
