How lenders calculate bank statement income
Qualifying income = average monthly eligible deposits × (1 − expense factor). The lender averages 12 or 24 consecutive months of deposits, removes anything that is not income, then applies the expense factor to business statements.
- Eligible deposits. Transfers between your own accounts, refunds, loan proceeds and unusual one-off deposits are taken out first.
- Business statements. Usually a 50% expense factor; service businesses with low costs can get less, and a CPA letter or P&L showing your real expenses can lower it.
- Personal statements. Usually 100% of eligible deposits count as income.
- 12 or 24 months. 12 months favours income that grew recently; 24 months smooths out a strong year.
Example: $12,000 a month of business deposits at a 50% expense factor gives $6,000 of qualifying income. At a 43% debt-to-income limit that leaves about $2,580 a month for all debts, including the new mortgage payment, tax and insurance.
Most programs also expect about two years of self-employment, a credit score from roughly 620–680, 10–25% down and a few months of payments in reserve. These vary by lender.

Enter your average monthly deposits and debts, and the expense factor your lender quotes for business statements (50% is the most common). Personal-statement programs usually count all eligible deposits, so for them this estimate is conservative.

How to read a 12 month bank statement loan estimate
This result is most useful as a screening range. The number should help you judge whether the deal feels plausible before you spend time on a real file review. Enter the deposit average for the program you are quoting: a 12 month bank statement loan averages the last twelve statements, which favors a borrower whose income grew recently, while a 24 month program averages twice the history and usually lowers the qualifying figure if the earlier year was weaker.
The income haircut is the core assumption
The estimate moves because lenders do not usually count 100% of deposits as usable income. The expense factor is what turns gross inflows into underwritten income.
Debt load can erase a promising deposit story
A borrower can show strong deposits and still lose room quickly if recurring debt payments already consume too much of the DTI allowance.
A range is more honest than a single promise
Real approval still depends on reserves, credit, documentation quality, and the lender's own overlays. The value here is directional clarity, not fake certainty.
Why real statement analysis still changes the answer
The calculator is only as good as the assumptions fed into it. The actual statement package is where those assumptions get tested against reality.
Deposits need cleanup before they become income
Transfers, reimbursements, and one-off inflows can inflate the picture unless the statement is read carefully and the deposit story is normalized.
Recurring debt often shows up more clearly in activity than memory
Autopays, card payments, and loan patterns become easier to spot when you look at transaction history instead of relying on a rough borrower summary.
File quality affects whether the story is even usable
Beyond the numbers, lenders care whether the statement package is complete, coherent, and defensible enough to support the underwriting conversation.

Bank statement loan calculator: questions & answers
What is a bank statement loan?
A non-QM mortgage for self-employed borrowers that qualifies you on the deposits in your bank statements instead of the income on your tax returns. It suits business owners, freelancers and 1099 contractors whose write-offs make their taxable income look smaller than what they actually earn.
How do lenders calculate income from bank statements?
They add up the eligible deposits over 12 or 24 consecutive months, take out transfers between your own accounts, refunds, loan proceeds and other one-offs, and divide by the number of months. Personal statements usually count 100% of what is left; business statements are cut by an expense factor, most often 50%, unless a CPA letter or P&L supports a lower one.
What are the requirements for a bank statement loan?
Typically 12 or 24 months of complete, consecutive statements, about two years of self-employment, a credit score from roughly 620 to 680 at the minimum, 10% to 25% down depending on credit, and several months of payments in reserves. Exact limits vary by lender.
Is a 12 month or 24 month bank statement loan better?
A 12 month program averages your last year only, so it helps if your income grew recently. A 24 month program averages two years; it gives a lower figure if the earlier year was weaker, but some lenders price it slightly better.
Can I use personal bank statements instead of business statements?
Yes, many lenders accept personal statements, usually counting all eligible deposits as income. Business deposits mixed into a personal account can make the file harder to underwrite, so keep large business transfers easy to explain.
What hurts a bank statement loan application?
Missing pages or months, large deposits you cannot source, overdrafts and NSF fees, falling deposits in recent months, and personal and business money mixed in one account. An analysis of your statements shows these before a lender does.
Is this calculator a mortgage approval?
No. It is an estimate from the numbers you enter. Approval depends on credit, reserves, the property and the lender's own rules.
