Material Takeoff: Methods, Lists, and Examples

A material takeoff (also written material take off or MTO) is the measured list of every material a project needs, taken from the drawings and specifications before anyone puts a price on it. It answers one question: how much of each material do we need? Only after that does the estimate answer the second question: what will it cost?

This guide covers the material takeoff meaning, how to build a material take off list, how to estimate building materials step by step, a worked material take off example, and when it makes sense to hand the job to a professional. If you want the wider picture first, read our construction takeoff guide and our explainer on what a quantity takeoff is.

Material Takeoff Meaning: What It Is and What It Is Not

The material takeoff meaning is simple. You “take off” quantities from the plans: square feet of drywall, cubic yards of concrete, linear feet of conduit, number of doors. The result is a building material take off that a supplier can quote or an estimator can price.

The most common confusion is treating the takeoff as the estimate. They are different documents:

A takeoff without pricing is incomplete for bidding. An estimate built on a weak takeoff is unreliable however good the pricing is. For the pricing side, see our guide to estimating construction costs.

Why a Material Takeoff Matters

• Bid accuracy. Quantities drive almost every line of the estimate. A missed room or a wrong scale flows straight into your price.
• Purchasing. A clean MTO becomes the buyout list, so suppliers quote the same scope.
• Waste control. Knowing what you actually need prevents both shortages and over-ordering.
• Scope clarity. Writing every item down exposes gaps and conflicts between drawings and specs early.

What Goes Into a Material Take Off List

A useful material take off list is organized the way the work is built, not the way the drawings happen to be sheeted. Most contractors group by CSI MasterFormat division and then by area or floor. Each line should carry:

• Item description with size, grade or spec reference
• Location (floor, area, system)
• Net quantity and unit of measure
• Waste factor and the final order quantity
• Notes, assumptions and the sheet or spec section the quantity came from

That last column matters. When a number is challenged later, a source reference saves hours. Our article on estimate templates and examples shows layouts you can adapt.

How to Estimate Building Materials: A Step-by-Step Method

1. Collect the full document set. Drawings, specifications, addenda and schedules. Confirm sheet revisions so you are not measuring a superseded plan.
2. Read before you measure. Check scale, legends, general notes and typical details. Our guide on reading construction plans for estimating covers this step.
3. Break the project into trades and areas. Foundation, framing, envelope, finishes, MEP and so on. Measure one system at a time.
4. Measure net quantities. Use a scale ruler, an on-screen tool or model data. Count items from schedules and reconcile them to the plans.
5. Convert to purchasable units. Square feet become sheets, linear feet become sticks or rolls, volume becomes cubic yards or truckloads.
6. Add waste and rounding. Waste varies by material, cut complexity and crew. Document the percentage you use.
7. Review. Re-check scale, compare totals against similar projects, and have a second person scan for missed areas.
8. Hand off to pricing. The takeoff is complete when someone else could price it without calling you.

This is the practical answer to how to estimate building materials: measure net, convert to units, add documented waste, and review. Common mistakes in this chain are covered in our post on construction estimating mistakes.

Material Take Off Example: Three Quick Calculations

These samples show the arithmetic behind a material take off example. Waste percentages here are illustrative; use figures that match your crews and materials.

Concrete slab

A 30 ft by 20 ft slab, 4 in thick: 30 × 20 × (4 ÷ 12) = 200 cubic feet, or about 7.41 cubic yards. Adding 5% for waste and over-excavation gives about 7.8 cubic yards, so you would typically order 8.

Drywall

100 linear feet of wall at 9 ft high is 900 square feet per side. A 4 × 8 sheet covers 32 square feet, so one side needs 900 ÷ 32 ≈ 28.1 sheets. Adding 10% waste gives about 31 sheets per side.

Wall framing

100 linear feet of wall with studs at 16 in on center: (100 × 12 ÷ 16) + 1 = 76 studs. Add extra studs for corners, openings and intersections, then three plates (one bottom, two top), or 300 linear feet of plate stock.

Materials Estimating by Trade

Every trade has its own measuring rules and its own traps. Materials estimating for concrete depends on formwork, rebar and finishing. Drywall depends on ceiling heights, fire ratings and finish levels. Roofing depends on pitch, valleys and penetrations. If you need a trade-specific package, see our services for:

• Concrete estimation and masonry estimation
• Lumber takeoff and drywall estimation
• Roofing estimation and flooring estimation
• MEP estimation for mechanical, electrical and plumbing

When to Use Material Takeoff Services

Doing your own takeoff makes sense on small, familiar jobs. Material takeoff services make sense when:

• You are bidding more projects than your team can measure before the deadline.
• The project is outside your usual trades, such as MEP on a commercial job.
• You want an independent check on an in-house number before a large bid.
• You need a supplier-ready MTO material take off for purchasing, not just a bid.

Some firms position themselves as material takeoff consultants, meaning they advise on method and review your numbers. Others deliver the measured quantities as a service. Be clear which you need. If you simply want the quantities, a done-for-you takeoff is faster. If you want to build the skill in-house, a review-and-coach arrangement fits better. For the outsourcing trade-offs, read outsourcing construction estimating versus in-house estimators.

What to Expect From a Professional Material Takeoff

At American Estimation, our quantity and material takeoff services cover residential, commercial and industrial projects across the USA. The process looks like this:

1. You send plans and any specs or addenda through our contact page.
2. We review scope, trades and drawing completeness, then send a fixed-price quote before work starts.
3. Our estimators complete the takeoff using digital tools and review it before delivery.
4. You receive an editable Excel takeoff, or we work in your own template.

Fees depend on project type, size, drawing completeness and number of trades. You can see how it works on our estimating fee page. If you also need pricing applied to the quantities, our cost estimation service turns the takeoff into a bid-ready estimate.

Material Takeoff Checklist

• Scale verified on every sheet
• Quantities grouped by trade and area
• Counts reconciled to door, window, fixture and equipment schedules
• Waste factors documented, not buried
• Assumptions and exclusions written down
• Second-person review completed

FAQs

What is a material takeoff?

It is a measured list of the materials a project needs, calculated from the drawings and specifications, before pricing is applied.

What does material take off mean?

The material take off meaning is the same as above. It is also called an MTO, and sometimes a quantity takeoff when the focus is on measured quantities generally.

What is the difference between a material takeoff and an estimate?

A takeoff states quantities. An estimate prices them and adds labor, equipment, overhead, profit and contingency.

How do I estimate building materials accurately?

Measure net quantities from current drawings, convert to purchasable units, add documented waste, and have the result reviewed by a second person.

How much do material takeoff services cost?

Cost depends on scope, size and drawing quality. Request a quote with your plans and we will send a fixed fee before starting.
