The Job Profit Formula

Six inputs, one honest answer. Here's exactly what the calculator does with your numbers.

Labor at your cost rate

Use your loaded cost per hour — wage plus payroll taxes, workers' comp, and benefits — not the rate you charge the customer. Costing labor at your bill rate hides the profit you're actually making. Not sure of your number? Work it out with the hourly rate calculator.

Material charge vs. material cost

The job is costed at material_cost — what you paid. Your material markup is the extra you bill on top, and that lift lives inside the quoted price. Keeping them separate means your profit reflects real dollars, not a marked-up sticker price. Dial in the right markup with the markup vs. margin calculator.

Why overhead per hour matters

Your truck, insurance, phone, software, and shop don't stop costing money when you're on a job. Spreading them across billable hours means every quote carries its share — so a "profitable" job doesn't quietly leave the overhead unpaid. Find your per-hour number with the overhead & break-even calculator.

Note: markup raises what you can charge, so it feeds the quoted price you enter. The cost breakdown always uses your real material_cost, which is why the profit line is the money you actually keep.

A Real Job, End to End

Say a bathroom rough-in takes 16 hours at a loaded labor cost of $45/hr. You buy $500 of materials, allocate $20/hr of overhead, and quote the customer $2,200. Here's how the profit shakes out:

A 30% margin is healthy for trade work. Now change one thing: if you'd quoted $1,700 instead, the profit drops to $160 and the margin falls to about 9% — below the 10% line, where a single callback or a $150 material overrun turns the job into a loser. That's the difference the calculator surfaces before you commit to a price.

Job Profit Questions

How do you calculate profit on a job?
Add up your true job cost — labor (hours × cost rate), the actual material cost you paid, and overhead allocated by hours (hours × overhead per hour). Subtract that total from the price you quoted. What's left is profit in dollars. Divide profit by the quoted price and multiply by 100 for your profit margin. That's exactly what the calculator above does.
What is a good profit margin for a contractor job?
Most trade contractors target a net job margin of 20% or higher after labor, materials, and overhead. Under about 10% is thin — one callback, a material price bump, or an hour of rework can wipe it out, which is why this tool flags anything below that line. See the full pricing picture with the markup vs. margin calculator.
Why is material charge different from material cost?
Material cost is what you pay the supplier. Material charge is what you bill — your cost plus markup that covers procurement time, waste, delivery, and warranty. The calculator costs the job at what you paid and lets markup flow into the quoted price, so profit reflects real dollars. See the labor cost calculator template and job cost calculator template for detailed worksheets.
