How this topsoil calculator works
Area × added depth is converted into cubic feet, settlement allowance is added, and the total is expressed as both cubic yards and whole bags.
How to use it
- Area to cover. Enter the value in sq ft.
- Added soil depth. Enter the value in in.
- Bag size. Enter the value in cu ft.
- Settlement allowance. Enter the value in %.

What to do with the number
Loose soil can settle after watering and grading, which is why a settlement allowance is useful. For raised grades or deep fills, calculate each depth zone separately instead of averaging a very uneven site.
