Tarmac and tonnes

Tarmac Driveway Cost Calculator

Use this calculator for tarmac or asphalt driveway planning when your local quote uses metric tonnes or local installed pricing. It is useful for UK, Canada, and other non-U.S. comparisons.

Project inputs

Use area or length × width to answer how much asphalt you need and estimate material and installed cost for a basic project.

A little waste is normal for cuts, waste, and site cleanup.

A simple starting point for quick estimates.

Formula: area × thickness × density ÷ 2000, then add waste. The calculator converts metric input for you and uses 145 lb/ft³ for the base estimate.

Important unit

Match tonnes, tons, square metres, or installed job pricing before comparing quotes.

How to compare tarmac quotes

Ask each contractor to quote the same area, same compacted thickness, same base repair, and same cleanup scope. A cheap quote can look better only because important work is missing.

If your quote is per tonne, enter the local tonne price. If it is a full installed job price, use the calculator result as a quantity check rather than a final bid.

Using U.S. price pages?

Treat U.S. state bands as comparison notes only. Your local tarmac contractor sets the real price.

Check tonnes first
