Concrete Driveway Cost Calculator

This concrete driveway cost calculator estimates concrete volume, gravel base, rebar, forms, and material costs for a rectangular driveway project.

Formula notes

Concrete volume = length x width x depth; gravel base = length x width x gravel depth; cost = unit price x quantity for each material.

Worked examples

1. Example: a 10 m x 3 m driveway with 10 cm concrete depth needs 3 m³ of concrete; with a concrete price of 90 per m³ the concrete cost is 270.
2. A 6 m x 4 m driveway with 12 cm concrete depth needs 2.88 m³ of concrete; at 100 per m³ the concrete cost is 288.

How to use it

1. Enter driveway length, width, concrete depth, and gravel depth.
2. Adjust rebar and form details and unit prices.
3. Read volumes, lengths, piece counts, and total cost.

Frequently asked questions

Limits and interpretation

• The estimate is for material quantities only and does not include excavation, labor, reinforcement installation, finishing, or permits.
• Inputs like rebar spacing and edge spacing are design estimates; local building codes may require different specifications.
