A bank statement loan is a non-QM (non-traditional) mortgage. A Qualified Mortgage, or QM, is the CFPB's category for a loan with safer features that make it more likely you can afford it. A non-QM (non-traditional) loan sits outside that category, uses different documents, and still has to meet the federal ability-to-repay rule. For self-employed borrowers, the document is usually 12 months of bank statements instead of tax returns.
This calculator shows the first piece of that math: the monthly income a lender may count from your deposits.
How is income calculated from bank statements?
- Add up 12 months of eligible deposits.
- Divide by 12 to get an average monthly deposit.
- Subtract the expense factor. For a business account, a 50% factor keeps half of each deposit as income.
- The result is your estimated qualifying monthly income.
| Account | Typical treatment | When it applies |
|---|---|---|
| Personal | Deposits generally count at 100% | Every account holder must be on the loan |
| Business | 50% expense factor | The most common starting point |
| Business, heavy payroll | Up to about 70% factor | Builders and multi-location restaurants, case by case |
What does a worked example look like?
This is a hypothetical with simple math. It is not a program or a payment I am offering.
- A consultant's business account takes in $360,000 over 12 months. That averages $30,000 a month.
- At a 50% expense factor, her qualifying income is $15,000 a month.
- Her tax return, after write-offs, shows $96,000 of net profit. That is $8,000 a month.
Same business, same year, two very different answers. That gap is why this loan exists. The calculator above opens with these numbers so you can change them to yours.
What does this calculator not do?
- It does not remove non-revenue deposits for you. Take out transfers between your own accounts, loans and refunds before you enter a total.
- It does not size a loan the way underwriting does. The max loan figure assumes a 45% payment-to-income limit and a placeholder $350 a month for taxes and insurance.
- It does not know your credit, assets, property or program. Those decide the real answer.
