A ballpark, not a bid. Real quotes swing widely with site access, excavation, decking, and finishes. Get itemized bids from local builders before you budget.
Estimates for planning only — verify sizes and equipment before buying. For chemicals, always follow the product label, add chemicals to water (never the reverse), and test with a kit.

How it works

Inground pool prices track closely with size and construction type, so a useful first estimate is surface area times a per-square-foot rate, plus a lump for the extras that vary most. The calculator takes your pool's plan size, a construction type, and lets you edit both the rate and the extras to match local quotes.

The starting rates are typical US figures: vinyl-liner pools run around $55 per square foot of surface, fiberglass around $75, and gunite (sprayed concrete) around $90–125. A 32 × 16 ft pool is 512 square feet, so a fiberglass shell lands near $38,000 before decking, fencing, and equipment. Those extras — decking, coping, heater, fence, landscaping — are entered separately because they swing the total the most.

Treat the result as a ballpark to sanity-check bids, not a quote. Real prices depend heavily on site access, soil and excavation, permits, and the finishes you choose. Get itemized bids from local builders and use this to understand where the money goes.

Worked example
Size 32 ft × 16 ft = 512 ft² · fiberglass at $75/ft² · extras $5,000
shell = 512 × 75 = $38,400
total = 38,400 + 5,000 = $43,400

Questions about pool cost

Most inground pools land between about $50 and $125 per square foot of surface for the shell, so a 512 ft² pool runs roughly $28,000 (vinyl) to $64,000 (gunite) before decking and extras. Site conditions and finishes move the number a lot.
