How do I calculate my income from bank statements?

Short answer

Add up the deposits that are genuinely income over 12 or 24 months, leave out transfers between your own accounts, refunds and loans, then divide by the number of months. That monthly average is what lenders and landlords usually look at.

If you're self-employed, a freelancer or paid in cash, your bank statements are often your best proof of income. Mortgage lenders offering bank statement loans, landlords and visa or benefit applications may all ask for them, and many of them work the number out the same way: eligible deposits over a period, averaged per month.

Doing it by hand from 12 or 24 PDF statements is slow and easy to get wrong. Turn the statements into a spreadsheet first and the whole calculation is a few filters and a sum.

Step by step

  1. Download every statement for the period you need, usually the last 12 or 24 months, for each account that receives income.
  2. Convert them to Excel. With the batch converter you upload them all at once and get one Excel file per statement in a ZIP.
  3. Paste the transactions into one sheet, sorted by date. Check the first and last balances against the statements so nothing is missing.
  4. Keep only money in (positive amounts). The Category column suggests which rows are income and which are transfers; check each one yourself.
  5. Remove deposits that aren't income: transfers from your own accounts, refunds, loan or credit card advances, and one-off gifts or sales.
  6. Add a Month column and total each month with a pivot table or SUMIFS, then average the months.

What lenders and landlords usually exclude

  • Transfers between your own accounts. Money moved from savings isn't new income, and counting it twice is the most common mistake.
  • Large one-off deposits. Lenders often ask you to explain any deposit that's out of pattern, so have the paperwork ready.
  • Business expenses, if you use business account statements. Many bank statement mortgage lenders apply an expense percentage to business deposits, or ask your accountant for one. The figure varies by lender.
  • Refunds, chargebacks and reversed payments.

Rules differ between lenders, landlords and countries. Use your own figure to check you qualify and to spot problems early, then follow the exact method the person asking describes.

They'll still want the original statements

A spreadsheet is your working, not your evidence. Lenders and landlords almost always want the bank's own PDF statements, sometimes downloaded in front of them or sent directly by the bank. Send the originals and keep the spreadsheet to answer their questions.

How many months of bank statements do I need to prove income?
It depends on who's asking. Bank statement mortgage lenders typically use 12 or 24 months; landlords and other applications often ask for the last 2 to 6 months. Check the requirement before you start.
Should I use personal or business bank statements?
Whichever your income actually lands in, and whatever the lender accepts. If you use business statements, expect the lender to deduct business expenses, often as a percentage of deposits.
Can I convert scanned or photographed statements?
Yes. StatementFlow reads PDFs, scans and phone photos, and checks every running balance so a misread figure doesn't skew your total.
