Paving Cost Calculator
Paving Cost Calculator – Estimate Your Project Budget with Confidence
Planning a new patio or driveway? Whether you're laying down natural stone, concrete slabs, porcelain, or block pavers — knowing your cost ahead of time is crucial.
This free Paving Cost Calculator takes the guesswork out of pricing. Enter your dimensions, material costs, and slab size — and let the maths do the rest.
📐 Step 1: Measuring the Area
- Measure the length and width of your paving area.
- Break complex shapes into smaller rectangles and sum the total.
- UK users: Enter dimensions in meters
- US users: Use feet
Tip: Add extra margin for cuts and waste — always round up!
🧱 Step 2: Understanding Cost per Unit
There are two common ways to calculate paving cost:
- Cost per square meter/foot: Best for bulk materials or contractor quotes
- Cost per slab: Useful for DIY jobs or specific paver orders
The calculator works with both and shows a comparison.
📏 Step 3: Know Your Slab Size
To calculate cost per slab, you’ll need the dimensions of each slab:
- Metric: mm × mm (e.g. 600 × 600mm)
- Imperial: inches × inches (e.g. 24" × 24")
- Or directly in m² / ft² if pre-measured
The calculator automatically converts slab size to area in m².
♻️ Step 4: Add Wastage
Always plan for waste. Typical allowances:
- 10% for basic square or rectangular patios
- 15%+ for awkward shapes, diagonal patterns, or lots of cutting
Set your wastage percentage in the calculator and we’ll do the rest.
💰 Paver Prices – What to Expect

| Natural Stone | £45 – £100+ | $7 – $15+ |
