Topsoil Calculator
Yards, tons and bags, with depth presets for seed, sod and beds.
Soil & Dirt Calculators
Soil is sold by the cubic yard, delivered by the truckload, and weighs whatever the moisture in it says it weighs. These work out the volume first, then what it weighs and how many loads that is.
Fill Dirt Calculator
Volume with a compaction allowance for holes and low spots.
What these have in common
Every calculator here returns the same three things: cubic yards, tons and a bag count, because suppliers quote in all three and rarely in the one you asked for. Each also shows its working, so you can check the figure rather than trust it.
Densities come from one shared table, which means a chart on one page can never contradict the tool on another. Where a material genuinely varies, the page says so and lets you type your own figure in. Nothing here needs an email address.
