How inground pool cost is estimated
pool = water surface sq ft × 50-125 USD (Angi 2026) · + deck sq ft × 5-35 USD + add-ons
Builders and cost surveys price a pool by its size first. Angi's 2026 data put inground pools at 50 to 125 USD per square foot, 88 on average; HomeGuide's 2025 guide gives 80 to 250. A 16x32 pool has 512 sq ft of water surface: 25,600-64,000 USD by Angi's range, about 45,056 at the average, and 40,960-128,000 by HomeGuide's. The type of pool shifts where you land: vinyl sits at the low end, concrete at the high end.
| Pool | Sq ft | Angi 2026 (50-125) | Angi average (88) | HomeGuide 2025 (80-250) |
|---|---|---|---|---|
| 10x20 | 200 | 10,000-25,000 | 17,600 | 16,000-50,000 |
| 12x24 | 288 | 14,400-36,000 | 25,344 | 23,040-72,000 |
| 14x28 | 392 | 19,600-49,000 | 34,496 | 31,360-98,000 |
| 15x30 | 450 | 22,500-56,250 | 39,600 | 36,000-112,500 |
| 16x32 | 512 | 25,600-64,000 | 45,056 | 40,960-128,000 |
| 18x36 | 648 | 32,400-81,000 | 57,024 | 51,840-162,000 |

Vinyl, fiberglass or concrete
| Pool type | Angi 2026 | HomeGuide 2025 |
|---|---|---|
| Vinyl liner | 20,000-40,000 | 35,000-80,000 |
| Fiberglass | 25,000-60,000 | 45,000-100,000 |
| Concrete (gunite) | 65,000-120,000 | 50,000-120,000 |
Vinyl costs least up front but the liner is replaced every 10 years or so; the pool liner replacement cost calculator prices that. Fiberglass needs the least upkeep. Concrete lasts longest, 50 years or more, but needs a new surface every 10 to 15 years (HomeGuide), see the pool resurfacing cost calculator. To spread the cost, the pool loan calculator gives the monthly payment; running costs start with the pool pump electricity cost calculator.
