Driveway Cost Calculator (Concrete & Asphalt)

This calculator estimates the cost of a sealed driveway in New Zealand, whether you are pouring plain or exposed-aggregate concrete, laying asphalt, or setting pavers. A driveway is one of the larger one-off spends around a home, and the price per square metre varies a lot by surface, so a realistic estimate up front helps you choose a finish and avoid bill shock. As a rough guide, plain concrete often runs around $100 to $150 a square metre supplied and laid, exposed aggregate and decorative finishes are higher at roughly $150 to $250, asphalt tends to be a little cheaper than plain concrete for larger areas, and quality paving sits in the middle to upper range depending on the product. On top of the surface itself there is usually site preparation: excavation, a compacted base course, formwork or edging, and sometimes drainage or a crossing to the kerb, which is why a contingency is wise. You enter the driveway area in square metres, choose the surface, which sets a typical rate, add a figure for preparation and any extras, and choose a contingency. The calculator returns the total estimated cost, split into the surface cost, your extras and the contingency, along with the cost per square metre so you can check a quote on a fair basis. Use it to budget, to compare concrete against asphalt, or to decide whether a smaller or simpler driveway would bring the project within reach. Rates differ by region, access and site condition, so treat this as a planning estimate and get firm quotes from local contractors before committing.
