Labor-Only Quote Calculator
"I'll buy the materials, you just do the labor" shifts real risk onto you: wrong parts, late deliveries, defective fixtures — and the rework lands on your hours. Build the labor-only price with handling time and a risk load included, and get the terms the quote must state to survive.

Quote = (Labor + Handling + Risk load) ÷ (1 − Target margin)($304.00 + $38.00 + $34.20) ÷ 0.65 = $578.77The quote only works with the terms printed on it: warranty covers workmanship only — not the customer's material; delays or defects in supplied materials are re-quoted at the same effective rate; and the customer buys replacements, not you. Labor-only without those three sentences is a turnkey job's risk at a labor-only price — which is exactly why many contractors refuse it.
Electrical: where the number comes from
A homeowner buys her own ceiling fan and fixture online and asks an electrician for a labor-only install: a day of work, an hour to collect and verify parts, at a $38 burdened rate. (Illustrative example — use your own numbers.)
| Input | Value |
|---|---|
| On-site hours | 8 hrs × $38 = $304 |
| Material handling | 1 hr = $38 |
| Risk load | 10% |
| Target margin | 35% |
Result: $578.77 — an effective $72.35/hr with the material risk priced
Quoted at bare labor plus margin it would have been about $495 — the $84 difference is the handling time and the rework risk the customer's online purchase transferred. The quote only holds with the terms printed: workmanship warranty only, delays and defects re-quoted.

| Base cost | $304 + $38 = $342.00 |
| Risk load | $342 × 10% = $34.20 |
| Quote | $376.20 ÷ 0.65 = $578.77 |
| Effective labor rate | $578.77 ÷ 8 = $72.35/hr |
| Profit in the quote | $578.77 − $342 − $34.20 = $202.57 |
How this calculator works
Every result comes from the formulas below — the math shown is the math used. Change any input and results update instantly in your browser; nothing is sent to a server.
- Labor cost:
Labor Cost = On-site Hours × Burdened Rate - Material handling:
Handling = Handling Hours × Burdened RateCollecting, verifying and returning customer-supplied material is your time too. - Risk load:
Risk Load = (Labor + Handling) × Risk %Prices the rework and delay risk that shifts to you when you didn't supply the material. - Labor-only quote:
Quote = (Labor + Handling + Risk Load) ÷ (1 − Target Margin)
What the result means
The quote prices what labor-only actually transfers to you: handling the customer's materials and the rework risk of parts you didn't choose or see. The effective rate row shows what each on-site hour must earn for the job to hold its margin.
When to use it
Use it whenever a customer asks to buy their own materials — and pair the quote with written terms: workmanship warranty only, delays and defects re-quoted.

Common mistakes
- Quoting bare labor × hours with no risk load — turnkey risk at labor-only price.
- Absorbing pickup, verification and return trips as free time.
- Leaving the warranty scope verbal instead of limiting it to workmanship in writing.
Frequently asked questions
How much should I charge for labor only?
More than your labor divided by hours — because the job carries risks a turnkey job doesn't. A day of work at a $38 burdened rate with an hour of material handling and a 10% risk load prices at $478 with a 35% margin: an effective $59.75 per on-site hour. Quoting it at bare labor rate × margin is how labor-only jobs become the least profitable work you do.
Should I add a handling charge for customer-supplied materials?
Yes — either as an explicit line or inside the risk load. Collecting, checking the right parts arrived, and driving them back when they didn't is real time the customer's decision creates. Many contractors also require materials to be on site and verified before the start date, which moves most of the burden back to the customer.
What warranty applies on labor-only work?
Workmanship only, in writing: you warrant your installation for a stated period; the material carries the manufacturer's warranty, which the customer claims; and defects or delays in supplied materials are re-quoted at your rate. Without those three sentences, you've implicitly warranted a product you didn't sell and can't return.
Why do many contractors refuse labor-only jobs entirely?
Because the risk transfer is real and the customer rarely prices it: the installer becomes the free diagnostician of someone else's purchasing mistake, the schedule slips on their delivery dates, and disputes over whose fault the failure was have no clean answer. If you do take them, the risk load plus the written terms are what make the economics defensible.
