How to use this calculator
- Enter Sheets (4x8).
- Enter Rate per sheet in $.
- Press Calculate. The highlighted row is your order quantity; the note beneath it translates the number into real-world terms.
Formula & constants
2026 hung, taped and finished to Level 4: $55–$80 per 4×8 sheet all-in ($1.70–$2.50/sq ft). Material is ~$12–$18/sheet; the rest is labor and finishing. Every default in the fields above is editable — when your supplier’s spec sheet lists a different density, coverage rate or price, enter that number instead. The waste and compaction allowances follow common trade practice; see our methodology page for the derivation of each formula and the standards it references.
Where this fits in the project
Coating and finish quantities are coverage-rate problems: true surface area divided by the product’s rated coverage, plus a waste allowance. Prep drives success — a coating over unprofiled or damp concrete fails regardless of quantity accuracy.
How this connects to your project
No quantity stands alone — each material in the chain depends on the ones around it. These are the planning steps that pair with the drywall cost calculator:
- Drywall Calculator — Estimate installation cost from sheet count.
- Paint Cost Calculator — Drywall finishing cost is separate from painting cost.
- Insulation Calculator — Insulation is installed before drywall.
- Stud Calculator — Drywall is screwed to studs — framing affects drywall cost.
Frequently asked questions
What is a Level 4 vs Level 5 finish?
Level 4 is standard for paint; Level 5 adds a full skim coat for gloss paint and raking light — +$0.50–1.00/sq ft.
Why do small drywall jobs cost more per sheet?
Trip minimums — finishing requires 3–4 visits for coats regardless of size.
Last verified: — prices reflect current national averages. See our methodology.
Estimates are for planning. Material densities, coverage rates and prices vary by region and supplier — confirm final quantities before ordering, and check local code where structural or electrical work is involved.
