User-entered productivityBid scenario

Drywall Finish Level Estimator
Cost Calculator

Reconcile a measured area against your own board, waste, productivity, labor-rate, material-cost, and markup assumptions.

No finish-level productivity or price preset
Derive inputs from the actual GA-214 scope, substrate, height, access, board/layer layout, crew record, quotations, location and base date.

Who it's for: drywall contractors and estimators building a bid scenario before construction, from measured area and verified productivity.

Which drywall finish level does the project need?

Finish levels 0 to 5 are defined by the Gypsum Association's GA-214, Recommended Levels of Finish for Gypsum Panel Products. The level is a specification decision: it sets how many coats of joint compound go on joints, angles, fasteners and accessories, and whether the whole surface is skim-coated, so each step up adds labor and material. Take the level from the project specification, and confirm its definition and the mock-up requirement in GA-214 at gypsum.org before you price. We do not restate the definitions here, and we list no labor multipliers or rates per level: productivity and prices are your inputs below.

How to use this calculator

1
Measure and define scope
Record finish level, surfaces, layers, access and units.
2
Enter company evidence
Use current crew productivity, supplier quotations and chosen allowances.
3
Review exclusions
No layout, fastening, joints, beads, backing, access, schedule, tax or adequacy is derived.

The formula

Boards = ceiling(area × layers × (1 + allowance%) ÷ usable board area). Hours = area × entered hours per area. Total = (hours × labor rate + entered materials) × (1 + markup%).

Frequently asked questions

A common mistake: Arithmetic only; not a takeoff or quote.

No. It only applies entered bid assumptions after the project finish level is defined.
