Calculate patio →Work out concrete volume, premixed bags and an indicative cost for post holes.
Calculate fence posts →DIY jobs can get expensive when you guess the quantities. MyProjectMate helps you turn measurements into a practical starting estimate, using prices and product information you can edit yourself.
These calculators are for preliminary budgeting, not engineering or construction specifications. Follow product instructions and seek appropriate professional advice for structural or site-specific decisions.
Measurements use metres and millimetres, estimates use pounds sterling, and material quantities are rounded up to whole purchasable bags or slabs where relevant. All example prices are editable.
We're starting with garden projects and will add more calculators as the site develops.
