Asphalt Calculator

Estimate tons of asphalt from square footage, thickness, and asphalt density. Uses 145 lb/ft3 as a common planning default for driveway and paving jobs.

sq ft

Measure the finished asphalt surface only. Add aprons and widened edges if they will be paved.

in

Enter finished compacted asphalt thickness, not the stone base depth.

lb/ft3

145 lb/ft3 is a common planning default for compacted hot-mix asphalt if your supplier has not given a density yet.

Assumes one uniform compacted asphalt lift across the full area. For most driveway planning, 145 lb/ft3 is a practical default until your plant or contractor provides a job-specific density.

Results are planning estimates only. Confirm mix type, compacted density, lift thickness, and delivered tonnage with your paving contractor or asphalt supplier before you order.
