Why Use a Tarmac Driveway Calculator?

Tarmac (also known as asphalt) is priced by the tonne, but most people think in metres when measuring their drive. Our calculator does the hard work for you by converting your dimensions into:

  • Surface area in square metres
  • Tarmac volume in cubic metres
  • Estimated weight in tonnes
  • Estimated cost based on your price per tonne

No more guesswork – just fast, accurate driveway planning.

What Thickness Should I Choose?

For driveways, a typical tarmac depth is:

  • 50mm (5cm) for light domestic use
  • 75mm–100mm for heavier traffic or long-term durability

Our calculator supports any depth you enter, so feel free to experiment with different values to see how it affects cost.


Average Cost Per Tonne of Tarmac

The cost of tarmac is typically measured by the tonne, especially when quoting for large areas or resurfacing work. On average, the cost of tarmac per tonne ranges from £50 to £80, depending on the type of tarmac used (e.g. standard vs. SMA — stone mastic asphalt), delivery fees, and your location within Oldham.
For a standard residential driveway, you might require 2 to 5 tonnes of tarmac depending on the area’s size and depth. It’s also important to factor in the sub-base materials, labour, and finishing costs when budgeting for the full installation.

If you’re unsure how many tonnes your project will need, our team can provide a breakdown as part of your free site survey or guide you using our tarmac calculator.
