Check quoted job revenue against materials, labour, overhead, contingency and tax before sending a price.
Calculator
Labour cost = labour hours × labour cost rate. Direct cost = materials + labour cost + overhead. Contingency = direct cost × contingency percent ÷ 100. Total cost = direct cost + contingency. Profit = quote price − total cost. Margin % = profit ÷ quote price × 100.
This is the method behind the answer, so the result can be checked rather than simply trusted.Result: 531.00 profit · 21.24% margin. Assumption: Quote price and costs use the same currency and tax basis.
Labour cost = labour hours × labour cost rate. Direct cost = materials + labour cost + overhead. Contingency = direct cost × contingency percent ÷ 100. Total cost = direct cost + contingency. Profit = quote price − total cost. Margin % = profit ÷ quote price × 100.
Labour cost is 24 × 35 = 840. Direct cost is 700 + 840 + 250 = 1,790. A 10% contingency adds 179, so total cost is 1,969. Profit on a 2,500 quote is 531, and margin is 531 ÷ 2,500 × 100 = 21.24%.
Master’s Tip: price the job that will actually happen, not the perfect version. Access delays, waste, callbacks, parking, disposal, payment fees and extra admin should be visible before a quote leaves your desk.
Standard or basis: trade quoting arithmetic before local tax treatment. The optional tax field is shown as a separate customer total, but profit is calculated on the entered quote price and entered costs.
Methodology & Accuracy
CalculationTime pages are built around visible arithmetic: the formula, assumptions, worked example and practical limitations are shown so the result can be checked rather than simply trusted.
Labour cost = labour hours × labour cost rate. Direct cost = materials + labour cost + overhead. Contingency = direct cost × contingency percent ÷ 100. Total cost = direct cost + contingency. Profit = quote price − total cost. Margin % = profit ÷ quote price × 100.

Where a calculator follows a named legal, trade or industry standard, that standard is cited visibly. Otherwise the page uses transparent general arithmetic and states its limits.Master’s Tip: price the job that will actually happen, not the perfect version. Access delays, waste, callbacks, parking, disposal, payment fees and extra admin should be visible before a quote leaves your desk.
Add materials, labour, overhead and contingency to get total estimated cost, then subtract that cost from the quote price.
Quote margin is profit divided by quote price, expressed as a percentage. It shows how much of the selling price remains after estimated costs.
For profit checking, use your internal labour cost rate. The quote price already represents what the customer is paying.
No. Contingency is a cost allowance for uncertainty. Profit is what remains after expected costs and contingency are covered.
Only as a separate optional display amount. Use tax-exclusive or tax-inclusive pricing consistently according to your local rules.
Job quoting turns measurements, labour assumptions and risk into a price. A profit calculator helps because a quote can look healthy at the top line while losing money after labour, overhead and callbacks are included.
Trade quotes often fail when materials are priced carefully but labour, travel, disposal, small consumables, equipment wear or admin time are guessed too lightly. The calculator separates those layers so the printed report shows where the margin came from.
A contingency allowance is not a bonus. It recognises that site conditions, waste, rework and timing rarely match a perfect estimate. Keeping it explicit makes it easier to explain or adjust without hiding risk inside profit.
A job can have a positive estimated margin and still cause cash strain if materials are paid before customer deposits arrive. This page checks arithmetic profit; deposits, terms, retention, insurance and contract risk need their own review.
