Pool Cost Calculator

Estimate what a swimming pool really costs: installation by type and size, line-item components, 10-year operating cost, home-value ROI and monthly financing. All figures are planning estimates from 2024–2026 U.S. industry surveys — always get 3 itemized local quotes before you build.

Planning estimates only — not a contractor bid. Costs vary with soil, access, permits and local labor markets.

Ranges compiled from the Angi 2026 in-ground pool cost guide (national average $65,909, range $44,499–$87,349), a 2025 state-by-state analysis of 200+ projects (vinyl/fiberglass/concrete bands above), and a 2025 installer price update. Full citations in SOURCES.md. The estimator above reproduces these bands: a 14x28 ft vinyl pool prices at $33,560 here, within 2% of Angi published $34,000 average.

Worked examples

Every figure below is produced by the estimator engine on this page — change the inputs above and you can reproduce each one.

14x28 ft vinyl liner, pro install, national average

A classic rectangular vinyl pool, 392 sq ft surface, about 13,196 gallons.

Estimate: $33,560 (typical range $26,848 – $41,950)

Breakdown: structure and base install $33,560; add-ons and equipment none selected. This lands within 2% of Angi 2026 size-table average of $34,000 for a 14x28 pool.

16x32 ft fiberglass, West Coast, partial DIY

Fiberglass shell with waterfall, heater, salt system and automation; owner handles decking and landscaping.

Estimate: $73,488 (DIY savings $12,969)

Breakdown: shell $73,692; add-ons $5,750; equipment $7,015; regional multiplier applied; 15% partial-DIY discount.

20x40 ft concrete + spa, national average

Gunite pool with built-in spa, automatic cover and gas heater.

Estimate: $180,000 (typical range $144,000 – $225,000)

Breakdown: shell $145,000; add-ons $32,500; equipment $2,500.

24-ft round above-ground pool

Pro install of an oval-footprint above-ground kit, 14,883 gallons.

Estimate: $4,817 (typical range $3,854 – $6,022)

Nearly 7x cheaper than the vinyl inground example — the trade-off is seasonality, shorter life and little resale value.

Scope note: this calculator estimates pool installation and ownership cost. It does not size pools (see Pool Size Calculator), compute water volume or chlorine doses (Pool Volume Calculator, Pool Chlorine Calculator), or size pumps and heaters (Pool Pump Size Calculator, Pool Heater Size Calculator). Salt dosing math lives in the separate saltwater-pool tooling, not here.

Frequently asked questions

How much does an inground pool cost?

National surveys for 2024-2026 put a standard inground pool at $28,000-$55,000 for vinyl liner, $45,000-$85,000 for fiberglass, and $55,000-$150,000+ for concrete/gunite. Angi 2026 guide reports an average of $65,909 installed, with most homeowners paying $44,499-$87,349. This page estimator prices a typical 14x28 ft vinyl pool at $33,560.

How much does a pool cost per square foot?

Angi 2026 reports $90-$250 per square foot of pool surface for inground pools. In this estimator, a 14x28 ft (392 sq ft) vinyl pool at $33,560 works out to about $85.61 per sq ft. Concrete/gunite runs higher per square foot than vinyl or fiberglass.

What is the cheapest inground pool to build?

Vinyl liner pools are the cheapest inground option to install ($28,000-$55,000), but budget for a liner replacement of $1,200-$3,500 every 8-10 years. Modeled DIY operating cost for a vinyl pool is about $1,995 per year, or $19,950 over 10 years.

How much does an above-ground pool cost?

Angi 2026 reports an average of $1,100-$5,700 for above-ground pools, with DIY kits from about $800 and elaborate installs with decking up to $15,000. This estimator prices a 24-ft round above-ground pool with pro install at $4,817 (typical range $3,854-$6,022).

How long does it take to build an inground pool?

Typical timelines: fiberglass 3-6 weeks, vinyl liner 4-8 weeks, concrete/gunite 8-16 weeks plus curing time. Permits alone often take 3-4 weeks, and spring/summer contractor backlogs can add months, so start getting quotes a year ahead if you want to swim next season.

Do I need a permit to build a pool, and what does it cost?

Yes, almost everywhere: building, electrical and sometimes fencing permits are required for inground pools. Permit and fee totals commonly run $500-$2,000; individual permits can be as low as $50-$100 each. Budget 4-8 weeks for approval in busy jurisdictions.

Will a pool raise my homeowners insurance?

Usually, yes. Insurers commonly add $50-$150 per year for the increased liability, and most require code-compliant fencing plus a locking gate. Many agents recommend raising liability coverage to at least $500,000 when you add a pool.

Does a pool increase property taxes?

Often. An inground pool typically raises the assessed value of the property, and surveys report annual property tax increases of roughly $300-$800. This model uses $450 per year as a national placeholder; check your county assessor.

Does a pool add value to my home?

Inground pools add roughly 5-8% of home value nationally (about $26,000 on a $400,000 home), 10-15% in Sun Belt markets, and near zero in cold climates. That is 39.4% of an average $65,909 install, so most owners do not recoup the full project cost. Above-ground pools are usually treated as personal property and add little or no appraised value.

Is it cheaper to build a pool yourself (DIY)?

Labor is 25-55% of a typical inground project, so owner-builder projects can save roughly 15-30%. On a $50,000 project, a full owner-builder approach saves about $15,000 in this model. Partial DIY (owner handles decking, landscaping, cleanup) saves about 15%. Structural, plumbing and electrical work still needs licensed pros.

How much does it cost per month to finance a pool?

At 7% APR over 15 years, a $60,000 pool loan costs $539.30 per month with $37,073 total interest. At 8.5% APR over 20 years, an $85,000 loan costs $737.65 per month with $92,036 total interest. Use the Financing tab above with your own rate and term.

How much does it cost per year to maintain a pool?

Budget $1,200-$3,000 per year for a typical inground pool. This model estimates $1,995 per year ($166/month) DIY for a vinyl chlorine pool, or $5,375 per year with weekly pro service on a concrete saltwater pool with gas heat. Winterizing adds $200-$500 per year in cold climates.

Is a saltwater pool cheaper to run than chlorine?

Saltwater pools use less purchased chlorine (about $220/year here vs $420/year for a vinyl chlorine pool) but need a salt cell replacement roughly every 5 years, modeled as $160 per year in reserve. Many owners find saltwater slightly cheaper and easier on skin, but the upfront salt system costs about $1,600.

How much does a built-in spa add to a pool project?

A built-in spa typically adds $15,000-$20,000 on top of the pool (Angi 2026). In this estimator, a 20x40 ft concrete pool with spa, automatic cover and heater prices at $180,000 total, with $32,500 of that in add-ons.
