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 landscape fabric takeoff.

Bed area divided by net roll coverage after overlap, rounded up to whole rolls.

Worked example. Example: a 20 × 8 ft bed at 150 ft² per 3×50 ft roll with 10% overlap rounds to 2 rolls.

1. Measure the bed as a rectangle using average width.
2. Enter the roll you will buy. 3×50, 4×100 and 6×300 are not interchangeable.
3. Pins, tape and the mulch on top are separate lines.

Questions

Questions about landscape fabric

Under river rock or mulch?

Same fabric math. Product weight (2 oz vs 4 oz) is a spec, not this count.

Around plants?

Overlap more and cut X slits. That is what the waste field is for.

What is the formula ID?

This calculator publishes formula LND-FAB-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.
