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 deck stain takeoff.

Deck area times coats, divided by the labelled coverage per gallon, with a visible allowance for rails, stairs and end grain, then rounded up to whole gallons.

Worked example. Example: a 16 × 12 ft deck, two coats at 250 ft² per gallon with 10% waste rounds to 2 gallons.

1. Measure the walking surface. Add stair treads as extra length if they get the same product.
2. Enter the coverage from the can you will buy. Transparent stains cover more; solids cover less.
3. Stir and keep a wet edge. The waste field is not a second coat.

Questions

Questions about deck stain

Rails and balusters?

They add a lot of extra face. Raise waste or add a second takeoff for the rail package.

New wood vs resurface?

New wood often drinks the first coat. Use the lower coverage number on the label, not the best-case number.

What is the formula ID?

This calculator publishes formula LBR-STN-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.
