Landscaping calculators
Mulch, gravel, soil and outdoor material calculators.
- Mulch Calculator — Bags vs Bulk Cost UKEnter border measurements, depth, bag litres, the supplier's bulk increment, and optional prices to compare independently rounded bag and bulk orders.
- Soil Calculator UK — Topsoil in m³ & Bulk BagsEnter inside bed dimensions in metres, unfilled depth in millimetres, and your supplier’s actual m³ or litre package sizes to estimate topsoil without guessing a tonnes-to-volume conversion.
- Gravel CalculatorEnter the area dimensions in metres and the gravel depth in millimetres to get the cubic metres and tonnes to order, with wastage and an optional VAT-aware cost estimate.
How these landscaping calculators work
Each calculator starts from site measurements in metres and millimetres, converts them with a tested formula, shows the exact quantity and your waste allowance as separate lines, then rounds up to the package or order unit you actually buy. Prices are optional and always entered by you, so the estimate reflects your supplier rather than a national average.
