Planning rates only. Pick a currency — badges, inputs, and totals follow. Material is a rate. Labour is hours × a planning hourly rate. Equipment and delivery are this-job amounts.

Planning defaults are office figures, not a bid. US ready-mix in 2026 often lands around $125–165 per cubic yard delivered; place-and-finish commonly $2–4 per square foot. Replace every rate with a supplier or crew quote before you send the letter.

How this calculator works

A transparent drywall fasteners takeoff.

This calculator multiplies sheet count by screws per sheet, applies a visible allowance, then rounds to 1,000-count boxes.

Worked example. Example: 18 sheets at 32 screws each with 5% waste is 605 screws, which rounds to 1 box of 1,000.

1. Use the sheet count from the drywall calculator.
2. Raise screws per sheet for ceilings and 5/8 fire board.
3. Buy whole boxes — leftover is cheaper than a mid-hang store run.

Questions

Questions about drywall fasteners

32 per sheet?

A common 4×8 wall hang. Ceilings, 16 in O.C. framing and 5/8 board often want 40–50. Change the input.

Does this include nails?

No. It is a screw takeoff. Adhesive and nails are separate if the spec calls for them.

What is the formula ID?

This calculator publishes formula DW-FST-001, version 1.0.0. The ID stays on the result and on the estimate line.

Is this engineering advice?

No. Construclytic is a planning website, not a registered engineering or contracting firm. Field checks, codes and product data still sit with you.

Does Construclytic fetch live supplier prices?

No. Costs use the rate you enter. Construclytic does not fetch live supplier prices.
