Gravel Calculator
Estimate gravel volume, weight, and material cost from area, depth, density, waste, and price per tonne.
Formula
Gravel quantity
Volume = length x width x depth; tonnes = volume x density / 1000
A 5 m by 4 m area at 10 cm depth needs about 2 cubic meters before waste.
FAQs
Why enter density?+
Different gravel types have different bulk densities, so weight can vary.
Does it include compaction?+
No. Add waste or compaction allowance if your supplier recommends it.
How does the Gravel Calculator calculate the result?+
It uses the Gravel quantity: Volume = length x width x depth; tonnes = volume x density / 1000. A 5 m by 4 m area at 10 cm depth needs about 2 cubic meters before waste.
What information do I need to use the Gravel Calculator?+
