    How do I calculate my average bank balance from statements?

    Drop your statement PDFs or CSV files in the box, all months of one account together. The tool reads the balance at the end of each day from the first to the last transaction and averages it. You also see the lowest balance, the highest balance and the balance at the end of each month.

    How it works

    How to calculate your average bank balance from statements in 3 steps

    No app, no account and no waiting. The statement is read in your browser, so you see the totals, the charts and the balance check straight away.

    1. Add the statements

      Drop all the months of one account, as PDF or CSV.

    2. Read the check

      If the running balances match, the amounts add up. If not, fix the date or number settings.

    3. Read the balances

      Average daily balance, lowest and highest balance are in the cards. The table has each month.

    Tips

    Tips for average balance

    • Lenders may use the average of month-end balances, the average daily balance, or the lowest balance. The cards show all three.
    • Use statements of one account in one currency.
    • The average covers the first to the last transaction date, which may be a little shorter than the statement period.
    • Always check the numbers against your statement.

    Privacy

    Private by design: your statement never leaves your device

    Most online bank statement analyzers upload your PDF to a server. This one does not. The statement is read by your own browser, so your name, account number and every payment stay on your device. The PDF reader (PDF.js, an open source library) is loaded from FileXL when you add a PDF, and your file is never sent anywhere. You can watch the network tab of your browser to check, or turn off your internet once the reader has loaded.

    Need to send a file to someone? Upload it with FileXL and share a link. The limit of this tool is scanned statements: a photo of a page has no text to read, and reading it needs OCR on a server, which would mean uploading it.

    FAQ

    Average bank balance calculator questions, answered

    What is the difference between average daily balance and average monthly balance?

    The average daily balance uses the balance of every day. An average of month-end balances uses one number a month. They can differ a lot if the account moves a lot during the month. The tool shows both when it can.

    Will a bank accept this number?

    It is not an official document. Banks and lenders work from the original statements and may use their own method. Use this to know your numbers before you apply.

    Is my bank statement uploaded to a server?

    No. The statement is read and analyzed in your browser. The PDF reader is loaded from FileXL when you add a PDF, and your file is never sent anywhere. You can check the network tab of your browser while you use the tool.

    What does the check note at the top mean?

    The tool adds each amount to the previous balance and compares it with the balance on the statement. If they all match, the amounts add up. If some do not, a row may be misread or missing and the numbers below may be off.

    Can I give the result to a lender or a visa office?

    It is not an official document. Many lenders and offices ask for the original statements from your bank. Use the analysis to understand your own numbers, and use the original statements for the application.

    Can it analyze a scanned or photographed statement?

    No. A scan has no text to read, and reading it needs OCR on a server, which would mean uploading the statement. Download the PDF from online banking, or ask your bank for a CSV.

    Is this bank statement analyzer really free?

    Yes. There is no sign-up, no watermark and no limit on the number of statements, apart from a limit of 50 files and 50 MB each at a time. One small ad may be shown on the page.
