How do labor and material costs split on a renovation?
Why the split matters as much as the total
Two renovation quotes with the same bottom-line number can represent very different projects depending on how much of that total is labor versus materials. A quote weighted heavily toward materials suggests higher-end finishes with comparatively efficient installation, while a labor-heavy quote often points to a complex scope, difficult site conditions, or simply a contractor in a high labor-cost market. This calculator takes your project total and an estimated labor percentage to break the number into its two main components.
Knowing the split also tells you where you have room to negotiate: material costs are often fixed by the product you choose, while labor costs can sometimes be reduced by simplifying the scope, doing some demolition or prep work yourself, or adjusting the schedule to suit a contractor's availability.
Typical splits vary a lot by project type
Projects with expensive finish materials, such as a kitchen with custom cabinetry and stone countertops, often have materials making up 50 percent or more of the total. Projects that are mostly about skilled labor and few materials, such as refinishing hardwood floors or a full repaint, can flip that ratio, with labor taking the larger share. Structural work, like framing or foundation repair, also tends to be labor-heavy because of the skill and time required relative to the materials used.
Because these splits vary so much by project type, treat any default percentage in this calculator as a starting assumption and adjust it based on your own quotes or on the typical ratios discussed on your specific project's calculator page.
Using the split to plan DIY versus hired work
If labor is the larger share of a quote, taking on part of the work yourself, such as demolition, painting, or site cleanup, can meaningfully reduce the total even if you still hire out the skilled trades. If materials dominate instead, the bigger savings usually come from shopping around on products or choosing a slightly lower finish tier rather than from reducing labor hours.
Enter your own project total and, if you have one, your contractor's actual labor rate using the custom amount option, since posted averages can be well above or below what is typical in your specific market.
Keeping the numbers honest through the project
Change orders during a project tend to shift the labor-to-material ratio, since added scope mid-project is often disproportionately labor, covering rework and schedule disruption rather than new materials. Revisit this split periodically if your project changes significantly, and use our renovation budget calculator to track actual spending against both categories as the job proceeds.
For a clear comparison between bidders, ask each contractor to break out labor and materials separately rather than quoting a single lump sum, which makes it much easier to see where quotes actually differ.
How it's calculated
We apply a typical labor percentage for your project type to your total budget. The remainder is treated as materials, fixtures and supplies. Actual splits vary by region, contractor and project complexity.
Worked example
A $20,000 general renovation at about 45% labor: $9,000 goes to labor and $11,000 to materials, plus a suggested $2,000 contingency.
Frequently asked questions
+Why does labor share vary so much by project type?
Projects with expensive manufactured materials (like cabinets or countertops) have a lower labor percentage, while labor-intensive work like custom painting skews higher.
+Does this include permits and design fees?
No, those are typically separate line items. Budget for them in addition to the labor and materials split shown here.
+Can I save money by buying materials myself?
Sometimes, but contractors often get trade discounts that offset their markup, and they take responsibility for defects when they supply materials.
+Should labor cost more in expensive cities?
Yes, labor rates vary more by region than material prices, since materials are often priced nationally while labor reflects local wages.
+Can I enter my own labor percentage?
Yes. Choose "Custom labor share" under project type and enter the percentage from your own quotes.
