How to read a bank statement for MCA

The repayment on a merchant cash advance comes straight out of daily deposits — so the bank statement is the underwrite. Here’s how to read one the way a funder does, in six steps.

A business bank statement holds everything an MCA underwriter needs — if you know where to look. Work through it in order, and confirm each number ties back to the bank’s own printed totals as you go. Below is the exact sequence, with links to a deeper definition of each term.

  1. Confirm the statement is complete and reconcilable. Check the period covers a full month, the pages run in sequence, and the printed beginning balance plus deposits minus withdrawals equals the printed ending balance. If it doesn’t tie out, the statement is altered, incomplete, or misread — stop and get a clean copy.
  2. Separate true revenue from gross deposits. Go through the credits and set aside anything that isn’t sales: transfers between the merchant’s own accounts, self-Zelle, bounced-and-returned pairs, and loan or MCA advance disbursals. What remains is true revenue — the number you size the advance against.
  3. Measure the average daily balance. Track the end-of-day balance across every day of the month and average it. A healthy average daily balance shows the business holds a cushion between deposits, not just a spike on deposit day.
  4. Count NSFs and negative days. Tally returned items and NSF fees, and count the days the balance went below zero. Zero to two NSFs a month is usually fine; five or more, or a rising trend, is a serious risk signal.
  5. Find existing MCA positions. Scan for fixed, recurring ACH debits on a daily or weekly cadence going to a funder or servicer. Add up the combined daily debits and compare them to daily deposits to see how much cash is already committed.
  6. Roll it into a decision. Combine true revenue, average daily balance, NSFs, negative days and existing positions into a paper grade, then match it to your buy box to qualify, decline or counter the deal.

Step 1 — Reconcile before you trust anything

Before a single metric matters, confirm the statement is real and complete. The printed beginning balance + deposits − withdrawals should equal the printed ending balance, and the running balance should march down every page without a gap. This is also your fraud check: altered statements almost never reconcile to the penny. If the math doesn’t tie out, don’t underwrite it — get a clean copy or pull statements directly.

Step 2 — True revenue, not gross deposits

The biggest mistake in spreading a statement is treating every credit as revenue. Strip out transfers between the merchant’s own accounts, self-payments, reversed pairs, and any loan or advance disbursal. What’s left is true revenue — and it’s often materially lower than the deposit total the merchant quotes.

Step 3 — Average daily balance

Deposit totals hide how the money behaves. A merchant can deposit $80,000 and still be broke by the 20th. The average daily balance measures the cushion across the whole month — run the numbers yourself with the free ADB calculator.

Step 4 — NSFs and negative days

Count the NSFs and negative days. These are the plainest stability signals on the page: how often did the business try to spend money it didn’t have, and how often did it go negative? The NSF & negative days checker maps a month’s counts to a typical buy box.

Step 5 — Existing positions

Look for fixed, recurring debits that repeat daily or weekly — the fingerprint of an existing MCA position. Total them up: if a merchant already gives up $900/day to two funders, a third advance may be the one that breaks the account. This is where stacking detection lives.

Step 6 — Turn the read into a decision

Now combine the numbers into a paper grade and match it to your buy box. Strong true revenue, a healthy balance, clean NSFs and no heavy stacking is A/B paper; the opposite is C/D or a decline.

Do it in seconds, and keep it honest. mcaunderwriting.com runs all six steps automatically — transcribing the statement, computing each metric, and reconciling every figure against the bank’s own printed balances. When a number can’t be reconciled it’s flagged for review rather than served as confident, so you never fund on a misread.

Frequently asked questions

What do MCA underwriters look for on a bank statement?

Consistent monthly deposits, healthy true revenue, a solid average daily balance, few NSFs and negative days, no large unexplained transfers, and any existing recurring debits from other advances.

How do you calculate true revenue from a bank statement?

Start with total deposits, then subtract every credit that isn’t sales: inter-account transfers, self-transfers, reversed/returned pairs, and loan or MCA advance disbursals. The remainder is true revenue.

Can you read a bank statement PDF automatically?

Yes. A bank-statement scanner transcribes every transaction and computes the metrics in seconds. The key is trust: figures should be reconciled against the bank’s own printed running balance, not just extracted, so a misread number is caught rather than funded on.
