Material Cost vs. Labor Cost in Construction
Part of Cost & Estimating
Quick answer
On a typical construction project, labor runs about 50–60% of the cost and materials about 40–50%. Labor-heavy trades (framing, finish carpentry, tile) skew higher on labor; material-heavy work (roofing, flooring supply) skews the other way. Use a 40/60 materials-to-labor split as a planning default and refine per trade.
Splitting a project into materials and labor matters for budgeting, bidding and DIY decisions — doing the labor yourself only saves the labor share, and material price swings only move the material share.
Typical split by trade
| Work | Materials | Labor |
|---|---|---|
| New home (overall) | ~45% | ~55% |
| Framing | ~40% | ~60% |
| Drywall | ~30% | ~70% |
| Roofing | ~40% | ~60% |
| Flooring (tile) | ~35% | ~65% |
| Painting | ~20% | ~80% |
Why the ratio matters
- DIY only saves the labor share — a paint job is mostly labor, so doing it yourself saves a lot; supplying your own flooring saves less.
- Material price spikes (lumber, steel) only inflate the material portion of a bid.
- Labor-heavy trades are where local wage rates swing the total most.
- A suspiciously low bid often shorts labor — check the split.
The construction cost estimator reports materials and labor separately for your project, and has a 'materials only' mode if you're supplying labor yourself.
FAQs
What percentage of construction cost is labor?
Roughly 50–60% across a whole project, but it ranges from about 20% for material-heavy supply work to 70–80% for labor-intensive trades like drywall finishing and painting.
How do I estimate labor cost alone?
Take the all-in cost and multiply by the labor share (about 55–60% for general construction), or estimate crew hours × loaded hourly rate. The estimator does the split automatically from a project's typical ratio.
