Free Tool — Receipt Leak Calculator

See how much your job profit
is overstated.

When receipts hit the bank but skip the job, the IRS still gets the right number — but your next bid doesn't. Move the slider to your honest untagged rate. The number on the right is what your next similar bid will be low by.

"The IRS gets the right number. Your pricing doesn't."

A quick take from Joe on what untagged receipts actually cost you — not on the tax return, but on the very next bid. The slider math below shows it in dollars.

Quick truth check
Most people think missing receipts mean lost tax deductions. They don't — your bank feed catches everything that left the bank account, and your bookkeeper deducts it on the company P&L. What missing receipts actually break is JOB-LEVEL profitability. This calculator shows you what that costs you on the bidding side.

Two columns. Left: every receipt that hit the bank (your bank feed always catches them — the IRS gets the right number). Right: receipts that also made it onto a specific job (so the job-cost report tells the truth).
Deducted on company P&L
Bank feed catches them all. Always full.
0 receipts/yr
The IRS got the right number on your tax return.
Tagged to a specific job
Only the tagged ones reach your job-cost report.

Untagged dollars never make it to a job — your jobs look more profitable than they were.
Untagged $/year
$0
Receipts hidden from job reports — still deducted on company P&L.
Per-job overstatement
$0
Each job appears more profitable by this much.
Cumulative loss/year
$0
Total your bids are short across the year.
Per-job under-bid risk
$0
If you reuse the overstated profit as your benchmark, your next similar bid will be low by this much.
Untagged rate under 5% is healthy. 6–15% is fixable with a receipt-capture process. 16–25% is bidding-wrong territory. 26%+ means the next bid is very wrong.

The IRS got the right number off your bank feed. Your pricing didn't.
Methodology & Sources

How the math works. Every number on this page is a transparent calculation from your slider inputs. There are no industry-stat claims — only your numbers, run through the formulas below.

receipts/year = crew × receipts/wk × 52

untagged/year = receipts/year × untagged %

untagged $/year = untagged/year × avg receipt $

per-job overstatement = (untagged $/year) ÷ (similar jobs/year)

per-job under-bid risk = per-job overstatement × (1 + planned GM %)

cumulative loss/year = per-job under-bid × similar jobs/year

What this calculator does NOT claim. It does not cite an industry "average receipt-leak rate" or an "average contractor untagged %." Those would be industry-stat claims that need a real source. This tool is your slider × your math — pick the rate that's true for your business.

Sources. The §0.10 framing on what the bank feed actually catches is built into how QuickBooks Online and any modern bank-feed bookkeeping works — it's a product fact, not an industry stat. The Excel companion has the same explanation on the "Methodology — Cited" / "— Examples" / "— Sources" tabs (all empty for this tool — by design).
