Cost Breakdown vs Revenue
Target net margin for Canadian trades: 15–25%. Under 10% leaves little buffer for slow periods, warranty callbacks, or unexpected costs. Use this tool before quoting to ensure profitability.
Assumptions & Methodology
This calculator uses standard accounting definitions for contractor job profitability:
- Gross Profit = Revenue − Direct Costs (materials + labour + subs + equipment + other). This is profit before overhead.
- Net Profit = Revenue − Direct Costs − Overhead Allocation. This is your actual take-home profit from the job.
- Gross Margin % = Gross Profit ÷ Revenue × 100
- Net Margin % = Net Profit ÷ Revenue × 100
- Overhead Allocation is calculated as a percentage of the invoice amount. It represents your share of fixed business costs attributable to this job (vehicle, insurance, shop, phone, software, etc.).
- Ratings: Excellent ≥30%, Good 20–30%, Fair 10–20%, Poor <10% — based on net margin.
- This calculator does not account for income tax or HST/GST. Net profit shown is pre-tax.
Frequently Asked Questions
What's a good profit margin for a contractor?
For Canadian trades and handymen, a net profit margin of 15–25% on a job is considered healthy. Gross margins (before overhead) of 30–45% are typical targets. Margins below 10% net leave very little room for error, slow periods, or warranty callbacks.
Specialty trades (electricians, plumbers) often command higher margins. General handymen and painters are typically in the 15–25% net range on well-priced jobs.
What's the difference between gross margin and net margin?
Gross margin is the profit after subtracting only the direct costs of a job (materials, labour, subs). It tells you if your pricing covers your field costs.
Net margin also deducts a portion of your overhead (insurance, vehicle, phone, etc.). It's a better measure of actual profitability — if your net margin is 5%, you're barely breaking even after all your real costs.
What counts as overhead for a contractor?
Overhead includes any cost that isn't directly tied to a specific job: liability insurance, vehicle costs (beyond direct mileage), tools and equipment maintenance, phone and software subscriptions, accountant fees, advertising, and any shop or office rent. A common approach is to total your annual overhead and divide it proportionally across your billable revenue — typically 10–15% for a solo handyman, higher for a company with office staff.
Why is my margin lower than expected?
Common margin killers in the trades: underestimating labour time (the #1 issue), forgetting small material costs (screws, tape, consumables), not charging for drive time, pricing materials at cost instead of marked-up, and omitting overhead entirely from job pricing. This calculator helps surface those gaps — run it on past jobs to see where your estimates went wrong.
How do I use this calculator to price future jobs?
Use it in reverse: estimate all your costs first, set your target net margin (e.g. 20%), then back-calculate the invoice amount needed. If Direct Costs = $6,000 and Overhead = $700 (at 10%), your Total Cost = $6,700. For a 20% net margin: Invoice = $6,700 ÷ (1 − 0.20) = $8,375. Round up to $8,500 and confirm the gross margin looks right. Never price from "what will the client pay" down — always price from "what are my costs" up.
Understanding Contractor Profit Margins in Canada
Profit margin is the single most important metric in a trades business — yet it's one of the least understood. Many contractors stay busy their entire careers without ever truly knowing if they're making money. This calculator, and the concepts behind it, are designed to change that.
Why Most Contractors Underprice Jobs
The most common pricing mistake in the trades is estimating material costs accurately and then guessing at everything else. Labour gets underestimated (the job "always takes longer"), overhead is ignored entirely ("I don't have an office, so I have no overhead"), and the resulting quote is too low to actually sustain the business. Running this calculator on every job — especially jobs that felt unprofitable — is a fast way to identify where the leakage is.
What Is a Healthy Margin for Canadian Trades?
Industry benchmarks for Canadian small contractors and handymen:
- Gross margin (before overhead): 35–50% is the typical target range
- Net margin (after overhead): 15–25% is healthy; 20%+ is excellent for a small operation
- Under 10% net: Danger zone — one warranty callback or slow month erases the profit
- Over 30% net: Excellent — usually indicates strong pricing power or very efficient operations
Overhead: The Hidden Cost Most Contractors Miss
A solo handyman working out of a pickup truck still has significant overhead: liability and tool insurance ($1,500–$3,000/yr), vehicle costs beyond direct mileage ($3,000–$6,000/yr), phone and apps ($600–$1,200/yr), accounting ($500–$1,500/yr), advertising ($500–$2,000/yr). Total: $6,000–$13,700 per year in overhead — which at 1,000 billable hours is $6–14/hr that must come out of every job's margin just to break even.
How to Use This Calculator to Price Smarter
The most powerful use of this tool is prospective pricing — enter your estimated costs before quoting, set your target margin, and calculate the invoice amount you need. If that number feels too high for the market, you have three choices: find ways to reduce costs, accept a lower margin (and understand why), or walk away from the job. All three are valid. What's not valid is pricing blind and hoping the numbers work out.
