12 or 24 Months? Personal or Business Bank Statements?
Choose 12 months when your income has grown recently — it averages only your most recent, stronger period. Choose 24 months when deposits swing month to month or the loan amount is larger, since it produces a steadier average. For the account type: personal statements are simpler and their deposits are generally counted as-is, while business statements have an expense factor applied (typically 50%, lower with a CPA letter or P&L). Business statements usually win when your business revenue is much higher than what you transfer to your personal account.
Key Facts
How the Statement Period Changes Your Income
The lender totals qualifying deposits over the period and divides by the number of months. If your business grew this year, a 12-month average captures only the stronger recent months; a 24-month average pulls in the slower year before and lowers your number. If your deposits are seasonal or uneven, the opposite can be true — 24 months smooths out the dips, and it is sometimes required for higher loan amounts.
12 vs. 24 Months: An Example
Say you deposited $25,000 a month last year and $35,000 a month this year into a personal account. A 12-month average is $35,000/month, or $420,000/year. A 24-month average is $30,000/month, or $360,000/year. The 12-month option qualifies you on $60,000 more annual income. Reverse the trend — a strong prior year and a slower current one — and 24 months comes out ahead.
Personal Bank Statements
Personal statements are the simpler path. Because the money in your personal account has already come out of the business, lenders generally count those deposits as-is with no expense factor. They work well when you pay yourself regularly and most of your earnings flow to your personal account.
Business Bank Statements
Business statements show gross revenue, so the lender applies an expense factor to estimate net income — typically 50%. A CPA letter or CPA-prepared P&L documenting your actual expense ratio can lower that to 30–40%, which directly increases qualifying income. Business statements are usually the better choice when your revenue is much higher than what you transfer to yourself — common if you reinvest heavily, hold operating reserves, or pay expenses straight from revenue.
Personal vs. Business: An Example
A business deposits $50,000 a month and the owner transfers $20,000 a month to their personal account. Personal statements qualify on $20,000/month. Business statements at a 50% expense factor qualify on $25,000/month — and at a CPA-documented 35% factor, $32,500/month. Check your own numbers with the bank statement income calculator.
What Can Trip Up the Deposit Analysis
Transfers between your own accounts are not income and are backed out to avoid double-counting. Large deposits that aren't business income — a family gift, an insurance payout, a brokerage transfer — need to be explained and sourced. NSFs on a business account during the statement period can raise flags. Consolidating deposits into one primary business checking account keeps the analysis clean. Ready to gather your file?
