An in-ground concrete pool costs $50,000–
Annual maintenance: $3,000–$5,000 for chemicals, cleaning, equipment and repairs.
Use this calculator at the planning stage of any construction or renovation project — before purchasing materials. Ordering the right quantity upfront avoids both costly mid-project shortages and unnecessary waste.
The most costly mistake is ordering the precise calculated quantity with no waste allowance. Cuts, breaks, and fitting invariably consume 5–15% of materials beyond the theoretical coverage area. Always add a buffer before placing an order.
A homeowner tiles a 4.2m × 3.8m bathroom floor using 600mm × 600mm tiles. The calculator estimates 47 tiles needed plus a 12% waste allowance — recommending an order of 53 tiles to account for cuts around the perimeter and a spare in case of breakage.
Concrete: $50–100K. Vinyl liner: $30–60K. Fiberglass: $40–75K. Plus $3–5K/year maintenance.
