Estimate the cost and materials needed to install a new path using resin, tarmac, or stone.
Enter your path dimensions, choose your surface material and enter your price per m². The calculator works out the area, the volume and approximate material weight, and an estimated cost.
Material weight uses typical densities (tarmac 2.3, stone 1.6, resin aggregate 1.5 t/m³). Figures are a guide; depths vary by material and use.
Measure your path length and width in metres.
Enter the depth in millimetres (resin ~15–18mm, tarmac ~40–50mm, stone ~30–50mm).
Choose your material and enter your cost per m².

This calculator estimates the surface material and cost — excavation, sub-base and edging are quoted separately.
This calculator gives a fast estimate, but final prices depend on groundwork, access, edging and finish. For a precise, no-obligation quote, get in touch and we’ll be happy to help.
Resin paths are typically ~15–18mm, tarmac ~40–50mm, and loose stone/gravel ~30–50mm over a prepared base.
Loose stone usually has the lowest material cost; tarmac and resin cost more but give a firmer, lower-maintenance finish.
No – it estimates the surface material and cost only. Excavation, sub-base and edging are quoted separately.
Yes – it works for any straight path. For winding paths, measure the total length and an average width.
