How to Estimate Income on Bank Statement or Asset Depletion Loans

The Quick Read: Estimating qualifying income starts with the documents, not your tax return. A bank statement loan averages 12 months of deposits and subtracts an expense factor for business accounts, while an asset depletion loan converts liquid savings into a monthly income figure. Both qualify on documented income under the applicable program, subject to lender guidelines.

• Bank statement income equals average eligible monthly deposits, minus non-income credits, minus an expense factor for business accounts.
• Asset depletion income equals eligible assets, after discounts and cash to close, divided by a set number of months.
• Select lenders in Lendmire’s network go up to 90% LTV on a primary-residence purchase or rate-term refinance with bank statements, and up to about 80% LTV on a primary residence with asset depletion.
• Owner-occupied cash-out tops out at 80% LTV, and investment-property cash-out at about 75% LTV.
• Expense factors, discounts, and divisors vary by lender, so any estimate you run yourself is a starting point only.

Self-employed borrowers know the problem. The tax return shows a modest number because of deductions and depreciation, while the bank account shows real money moving. Retirees and business sellers face the opposite problem: plenty of savings, almost no paycheck. These two loan types exist to bridge that gap, and the math behind each is simpler than most borrowers expect. What follows walks through both, shows where the estimates break, and explains when neither is the right tool.

Which Method Fits Your Situation?

Bank statement documentation fits borrowers with steady deposits and weak tax-return income. Asset depletion fits borrowers with large liquid balances and little regular income. Many borrowers could use either, and the answer often comes down to which one produces the larger, more defensible figure.

What Does Each Loan Actually Do?

A bank statement loan assesses a borrower’s income based on deposit history. A lender reviews 12 months of personal or business statements and derives monthly income from the averages. That is the window across most programs in Lendmire’s wholesale network. Experian describes the same basic idea, with borrowers supplying personal or business statements covering the prior one to two years.

An asset depletion loan skips deposits entirely. The lender takes your eligible liquid assets and spreads them over a fixed number of months to create imputed income. You do not have to sell anything. The assets stay where they are, and they simply stand in for a paycheck on paper.

Neither product is undocumented. Lenders must verify the income or assets they rely on using reliable third-party records, as the eCFR text of Regulation Z §1026.43 spells out. The documents differ from a conventional file. The verification does not go away.

Key Terms Defined

Qualifying income: the monthly income figure a lender uses to judge whether you can carry the payment.

Expense factor: the share of business deposits a lender treats as operating costs rather than income.

Lookback window: the number of months of statements the lender averages, commonly 12.

Divisor: the number of months over which eligible assets are spread to create monthly income.

Haircut: a discount applied to an asset because it could lose value or is harder to access.

Seasoning: how long funds have sat in your account, which shows they are really yours.

How to Estimate Bank Statement Income, Step by Step

Start with raw deposits, clean them, apply the factor, then average. Each step moves the number, and the cleaning step is where most self-estimates go wrong.

1. Gather 12 consecutive months of statements. Use the business account if the business pays you, or the personal account if you deposit your own earnings there.

2. Total the deposits. Add every credit for the full window.

3. Remove non-income credits. Transfers between your own accounts, loan proceeds, refunds, and one-off gifts do not count as earnings.

4. Apply the expense factor to business accounts. A lender assumes part of every business deposit went to costs. Personal-account deposits are typically counted with little or no haircut, depending on the program.

5. Divide by 12. The result is your estimated monthly qualifying income.

Notice what drives the result. The expense factor is set by lender guidelines, not by you, and it often depends on business type. Some lenders will use a different factor when an accountant prepares a ratio, and that is program-dependent. Never assume a specific factor before you see a lender’s sheet. Across the wholesale network, the spread between a strict program and a flexible one can change qualifying income materially on the same statements.

What counts and what does not:

When the Lookback Window Matters

Where a program allows a choice of window, borrowers often compare a shorter and longer period. A growing business may look better on the recent months. A seasonal one can look inflated if the 12 months capture only the busy stretch, and a longer window tends to give the more honest picture. Declining deposits are the hardest case. A lender will notice the trend, and a written explanation helps, but it does not guarantee the file works.

How to Estimate Asset Depletion Income, Step by Step

Asset depletion is a subtraction followed by a division. The key is what gets subtracted before you divide.

1. List eligible assets. Cash, brokerage accounts, and vested retirement accounts are the usual candidates.

2. Apply discounts by account type. Stocks and funds can lose value, and retirement accounts are often discounted more heavily, particularly for borrowers under 59½.

3. Subtract cash needed for the transaction. Down payment and closing costs come out first, and some programs also set aside reserves, commonly around six months of the housing payment.

4. Divide what remains by the program’s divisor. The divisor is the biggest variable between lenders. A shorter divisor produces more monthly income from the same pile.

5. Treat the result as imputed income. It then feeds the debt-to-income calculation like any other income.

The trap is double counting. The same dollars cannot serve as cash to close and as income. A borrower who plugs the full account balance into an online calculator will see a number no lender will honor.

Select lenders in the network reach about 80% LTV on a primary residence with asset depletion, so the leverage is real. The income figure just needs to survive the subtraction first. Every figure here varies by lender and program: guidelines, property type, leverage, and credit profile all apply.

Same Borrower, Both Methods

Picture a consultant with a growing practice and a sizable brokerage account. On paper, the tax return understates her earnings. Her business statements show strong, steady deposits, but the expense factor takes a visible bite out of them. Her brokerage account, after discounts and cash to close, produces a different figure through the divisor.

Which wins? There is no universal answer. A borrower with high deposits and modest savings will usually see more income from bank statements. A borrower with large balances and thin deposits will see more from assets. The right move is to run both with a lender’s actual factors and compare. Some programs also let a borrower combine the two, using assets to supplement deposit income. Confirm that by program, because others require asset depletion to stand alone.

From Income to Buying Power

Estimated income only matters once it meets the debt-to-income test. Lenders add up your proposed housing obligation plus other monthly debts and divide by qualifying income. The higher your documented income, the more room you have. Experian notes that market lenders may look for a debt-to-income ratio of 50% or less on bank statement loans, but that is a market-wide survey figure, and individual programs differ.

Here is the practical sequence. Estimate income both ways. Subtract your existing monthly debts from what a lender could allow. Then work backward to a housing budget. The site’s illustrative calculator can help you test scenarios, though it is an estimate and not a quote.

Where the General Rule Breaks

The formulas above describe the typical file. Several situations bend them.

Commingled accounts. Mixing personal and business money blurs which deposits are earnings. Expect scrutiny of large transfers.

High deposits, low balances. If money arrives and leaves just as fast, a lender may question how much is truly disposable.

Odd assets. Real estate equity, business interests, and crypto are often excluded or treated unevenly. Retirement accounts depend on your age and access.

Occupancy. This one reshapes everything. A bank statement loan on an owner-occupied home, whether primary residence or second home, is a consumer mortgage, and consumer disclosure rules such as TRID apply. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is business-purpose and exempt from TRID. The CFPB’s Regulation Z §1026.3 treats credit to acquire or maintain non-owner-occupied rental property as business purpose.

For many rental purchases, personal income is not the main event at all. Business-purpose investor loans are reviewed differently from a standard owner-occupied mortgage, and investors with several financed properties often find property-level rent coverage, the DSCR route, the cleaner path. Lendmire’s complete DSCR loans guide covers that lane. Bank statement and asset income earn their place on owner-occupied files, or where a borrower’s capacity matters as a secondary factor.

What Leverage Can You Expect?

Leverage depends on occupancy and transaction type. These are typical ranges from select wholesale-network lenders, subject to lender guidelines, credit profile, and property review.

Loan sizes generally run from $125,000 to $3,500,000, with reserves commonly around six months. The strongest files earn the top of each range. For owner-occupied cash-out, the 80% ceiling applies with a fixed expense ratio, which can differ by loan size and credit, and an accountant-prepared expense ratio is a separate option under the same program. Alt-doc loan terms follow each lender’s program sheet, so term length is something to confirm file by file.

Consumer mortgage licensing for this lane covers 16 states, so availability is narrower than on the investor side.

Common Mistakes That Shrink Your Number

• Counting gross business deposits as income.
• Leaving transfers and loan proceeds in the deposit total.
• Using the full asset balance and ignoring cash to close.
• Assuming a retirement account counts at face value.
• Picking an expense factor yourself instead of reading the lender’s.
• Depositing large sums right before applying, which invites seasoning questions.

Cleaning up before you apply helps. Keep business and personal money separate, document unusual deposits, and avoid moving money around in the months before a file goes in.

Another point worth knowing: both methods typically involve larger down payments or stronger credit than a standard file, a point Experian also raises. Documentation flexibility has a price in leverage or terms. Even then, a lender cannot rely on a borrower’s word alone, as the CFPB small entity compliance guide makes clear.
