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 fill dirt takeoff.

Area times compacted depth, plus a visible swell so the compacted thickness lands, rounded to the next 0.1 yd³ and converted to tons at the density you enter.

Worked example. Example: a 20 × 12 ft pad 12 in deep, 1.2 t/yd³ and 20% swell rounds to 10.7 yd³, about 12.8 tons.
  1. 1. Measure the area that will receive fill, not the excavation unless they match.
  2. 2. Enter compacted depth. Swell lives in the waste field so a 12 in pad is not ordered as 12 in of loose dirt.
  3. 3. Confirm density with the pit. Topsoil, fill dirt and engineered fill are not the same.

Questions

Questions about fill dirt

Is this topsoil?

No. Use the soil calculator for planting beds. This page is structural or grade fill, with swell in the open.

Does this include haul-off?

No. Export and import are separate lines. Pair it with the trench calculator when you are swapping material.

What is the formula ID?

This calculator publishes formula LND-FIL-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.
