Hourly Labor Rate ? Your fully-loaded labor cost per hour — include wages, workers' comp, and payroll taxes if applicable.

Project Costs

Material Cost ? All supplies, materials, and parts for this job. Include a markup if you resell materials to clients.

Understanding Your Quote

What Goes Into a Quote

A profitable quote covers labor, materials, equipment, travel, overhead, a contingency buffer for surprises, and your profit margin. Leave any one out and you absorb that cost yourself.

Quote = (All Costs + Overhead + Buffer) + Profit

Why Overhead Matters

Overhead includes insurance, vehicle costs, admin time, licensing fees, and office expenses. These are real costs spread across every job. A typical contractor overhead runs 10–20% of job cost.

Overhead Cost = Base Cost × Overhead %

What Is a Contingency Buffer?

Jobs rarely go exactly as planned. Hidden damage, bad weather, extra material needs — a contingency buffer absorbs these without killing your margin. 10% is standard for most jobs.

Buffered Cost = Cost × (1 + Contingency %)

Break-Even vs Quote Price

Break-even is the floor — the minimum you must charge to avoid losing money. Your quote price is above that floor by your profit margin. Never negotiate below break-even for any reason.

Break-Even = Total Cost incl. Overhead + Buffer

Why contractors underquote — and how to stop

Forgetting overhead entirely. Insurance, licensing, admin, vehicle costs, and office expenses are real costs that belong in every quote. Most contractors skip them and then wonder why the numbers don't work out.
Underestimating labor hours. Jobs always take longer than expected. Add a realistic estimate, then add a buffer. Quoting the best-case scenario means you work for free when reality hits.
No contingency for surprises. Hidden damage, material shortages, weather delays, and scope creep happen on almost every job. A 10% buffer is not padding — it's professionalism.
Competing purely on price. Clients who only want the lowest price are often the most difficult. Quote your real costs, hold your margin, and let the right clients find you.
Confusing revenue with profit. A $10,000 job sounds great until you account for $9,200 in costs. Know your break-even on every job before you send the quote.

Frequently Asked Questions

Most trade contractors run 10–20% overhead. Solo operators with minimal admin costs can use 10–12%. Businesses with employees, a physical office, a fleet of vehicles, or significant insurance costs should use 15–20% or higher. Track your actual overhead annually and update accordingly.

Treat subcontractor costs like a direct job cost. You can add them to the material cost field or calculate the subcontractor total separately and add it there. Make sure you still apply overhead and margin on top — you're managing the sub and taking on the liability.

Net profit margins for contractors typically range from 10–25%. Specialty trades (electrical, HVAC, plumbing) can often command 20–30% on service calls. Remodeling and general contracting often runs 15–25%. Below 10% net margin leaves no room for error or business reinvestment.

Only lower the price if you can remove scope — fewer hours, less material, a smaller job footprint. Never reduce your margin below break-even. If the client can't meet your minimum, it's better to decline the job than to lose money completing it. Unprofitable jobs drain time and cash you could spend on profitable ones.

Yes — most contractors mark up materials 10–20%. You source, transport, and manage the materials. Your time and expertise have value beyond just the labor hours. If you're entering your material cost here, consider whether it's already marked up. If not, factor the markup into the overhead or profit margin slider.

Revisit your labor rate at least once a year, and any time wages, insurance costs, or benefits change. Many contractors undercharge because they set a rate years ago and never raised it. Inflation, insurance premiums, and wage increases erode margin over time without a rate adjustment.
