Labor vs Material Cost Split by Trade (USA 2026)
What share of your bill is labor on 18 common trades — and what that means for DIY savings, supplied materials and negotiating a quote.
The split tells you where DIY actually pays
Every quote is materials plus labor plus overhead. When labor is 70% of the number, doing the work yourself is where the savings live. When labor is 25%, DIY saves little and risks a lot — you are mostly buying the same materials the contractor would, without the trade discount.
Use the split as a decision filter before you decide what to take on.
Labor share by trade
Percentages are of the installed price, at typical residential scope, excluding permits.
| Trade / task | Labor share | Material share | DIY verdict |
|---|---|---|---|
| Interior painting | 80–85% | 15–20% | Best DIY value on this list |
| Demolition | 85–90% | 10–15% | Strong DIY value (mind dust and asbestos) |
| Drywall finishing | 75–80% | 20–25% | Good DIY value, steep skill curve |
| Tile setting | 60–70% | 30–40% | Good value if you are patient |
| Landscaping / sod | 65–75% | 25–35% | Good value, high labor input |
| Framing | 55–65% | 35–45% | Only with real carpentry experience |
| Trim carpentry | 60–70% | 30–40% | Doable, finish quality shows |
| Deck building | 50–60% | 40–50% | Doable; get the permit |
| Concrete flatwork | 50–60% | 40–50% | Small pours only — finishing is a timed skill |
| Fencing | 50–60% | 40–50% | Doable |
| Roofing (asphalt) | 50–60% | 40–50% | Not recommended — fall risk, warranty |
| Siding | 45–55% | 45–55% | Not recommended above one story |
| Electrical | 60–70% | 30–40% | Licensed work in most jurisdictions |
| Plumbing rough-in | 55–65% | 35–45% | Licensed work in most jurisdictions |
| HVAC install | 35–45% | 55–65% | Licensed; equipment dominates |
| Flooring (LVP) | 40–50% | 50–60% | Good DIY value on click-lock |
| Cabinet install | 35–45% | 55–65% | Cabinets dominate the number |
| Window replacement | 30–40% | 60–70% | Units dominate; DIY saves little |
Why supplying your own materials usually backfires
Contractors buy at trade pricing, often 10–25% below retail, and that discount is frequently baked into the quote. When you supply materials you give that up, you take on responsibility for quantity errors and back-orders, and most contractors will not warrant labor on materials they did not select.
The exception is high-ticket selectable items — tile, plumbing fixtures, light fixtures, appliances — where the homeowner chooses a specific product anyway. Buying those yourself is normal and expected.
- Do supply: tile, fixtures, appliances, hardware, paint colors you insist on
- Do not supply: lumber, fasteners, sheet goods, concrete, adhesives, anything measured on site
Reading a quote with the split in mind
If a quote lists a labor number that is wildly outside the ranges above, ask why. Sometimes the answer is legitimate — difficult access, a second story, lead-safe practices, a tight schedule. Sometimes it is padding, and asking the question politely surfaces it.
Conversely, an unusually low labor number on a licensed trade is a warning sign, not a bargain: it often means an unlicensed sub, no insurance, or a scope that quietly excludes the hard part.
