For rectangular pools: calculate an even-width deck ring, concrete quantity and a custom budget.
How the estimate works
Deck area = (length + 2 × deck width) × (width + 2 × deck width) − pool length × pool width − excluded area. Concrete cubic yards = net area × thickness in inches ÷ 12 ÷ 27. Waste applies to material quantities; installation budget uses net finished area. This models an even rectangular ring, not generic deck boards or an irregular patio. Design drainage, base, reinforcement, joints and bonding with a qualified local professional.

Volume uses US gallons; dimensions use feet and inches. All budget inputs use the same currency chosen by you. Replace demonstration values with measurements and quotes. Calculations are planning estimates, not equipment specifications or contractor offers.
