- Add 10% allowance.
- Apply selected product coverage and round up.

Questions about this calculator
Compacted or loose thickness?
Always enter compacted finished thickness for tonnage estimates.
Why does density matter?
Asphalt mix density changes tons per cubic yard; use your supplier’s value when available.
Can I use mixed units?
Yes. Choose feet, inches, metres or centimetres and the calculator converts each input before calculating.
Is this a final material order?
No. Confirm drawings, product coverage, local code and site conditions before buying or building.
