Estimate what a new swimming pool will cost to install. Compare gunite, fiberglass, vinyl, and above-ground pools by size, add heater, deck, fencing, and more, and see a realistic low-to-high price range.
Get a realistic installed-cost range for a new pool before you call contractors. Pick the type, set the size, and add the extras you want — the estimate updates as you go.
Pool type
The construction type — by far the biggest cost driver. In-ground gunite is the most expensive and customizable; above-ground is the most affordable.
Pool surface area
The water surface area in square feet (length × width). A 16×32 ft pool is about 510 sq ft; a 14×28 ft pool about 390 sq ft.

A major home investment
At this level you're making one of the larger improvements a home can have. Get at least three detailed, written bids — not phone ballparks — and confirm exactly what each includes (excavation, permits, equipment, startup). Prices swing widely by region and contractor, so the spread here is real, not padding.
Estimates use 2026 national contractor averages and will vary with your region, site conditions, soil, finishes, and equipment choices. They don't include things like landscaping, water to fill the pool, electrical-panel upgrades, increased property taxes, or ongoing maintenance and energy costs. Always confirm scope and inclusions on written bids.
💡About this calculator▼
A new pool is one of the biggest projects a homeowner can take on, and the "how much does a pool cost" answers online range from a few thousand dollars to well over a hundred thousand — because the type of pool changes everything. This estimator gives you a realistic price range tailored to the pool you actually have in mind, before you start calling contractors.
Pick your construction type — in-ground gunite, fiberglass, or vinyl liner, or an above-ground pool — set the size, and toggle on the extras you want, like a heater, a deck, or safety fencing. The tool combines a base installation cost with a per-square-foot rate for your pool type and adds your selected features to produce a low-to-high installed estimate.
The range is wide on purpose: real pool quotes vary 30 to 50 percent depending on your region, site conditions, and finishes. The goal here isn't a to-the-dollar quote — it's a grounded number to budget around, to sanity-check the bids you receive, and to see how much each choice (type, size, and add-ons) actually moves the total.
Every estimate is built from three pieces: a base cost for your pool type, a per-square-foot cost that scales with size, and the flat cost of any add-ons you select. The tool adds them up into a low and a high figure.
Your pool type sets both the base cost and the per-square-foot rate, and it's the single biggest factor. A base cost covers the things that don't scale much with size — excavation or site prep, permits, the pump and filter equipment, and core labor. The per-square-foot rate then scales the price with your pool's surface area, since a bigger pool means more material, more excavation, and more finish work.
Construction type drives huge differences here. Gunite (sprayed concrete) is the most expensive and most customizable; fiberglass uses a pre-molded shell that installs faster for a bit less; vinyl-liner in-ground pools are the most affordable in-ground option; and above-ground pools cost a fraction of any in-ground build because there's little excavation and the structure comes as a kit.
Each add-on you toggle on — heater, deck or patio, safety fence, automatic cover, or saltwater system — adds its own typical cost range on top. The result is a low-to-high total, and a midpoint you can use as a single planning number. The exact formula and a worked example are below.
📐How it's calculated▼
The estimate combines a base cost, a size-driven cost, and add-ons — calculated for both a low and a high figure.
Step 1 — Pool and installation: Pool cost (low) = Base cost (low) + Surface area × Per-sq-ft rate (low) Pool cost (high) = Base cost (high) + Surface area × Per-sq-ft rate (high)
Each pool type has its own base cost and per-square-foot range. For example, gunite carries a higher base and a higher per-square-foot rate than vinyl; above-ground is far lower on both.
Step 2 — Add-ons: Add-ons (low) = sum of the low cost of each selected feature Add-ons (high) = sum of the high cost of each selected feature
Step 3 — Total range: Total (low) = Pool cost (low) + Add-ons (low) Total (high) = Pool cost (high) + Add-ons (high)
Example: A 450 sq ft gunite pool with a heater and a deck
→ Pool: base $15,000–$25,000 + 450 × $90–$160/sq ft = $15,000–$25,000 + $40,500–$72,000 = $55,500–$97,000
→ Add-ons: heater $2,000–$5,000 + deck $4,000–$12,000 = $6,000–$17,000
→ Total: $61,500–$114,000, with a midpoint around $88,000
That wide spread is normal for pool construction — which is exactly why getting several itemized bids matters.

🔍Finding your inputs▼
Pool type: The construction method, and the most important choice you'll make for cost. Gunite (also called concrete or shotcrete) is sprayed in place, fully customizable in shape and finish, and the most expensive. Fiberglass arrives as a pre-formed shell that drops into the excavation, so it installs faster and usually costs a bit less than gunite. Vinyl-liner in-ground pools use a steel or polymer wall frame with a replaceable liner and are the most budget-friendly in-ground option. Above-ground pools sit on the surface, need little excavation, and cost a small fraction of any in-ground build.
Pool surface area: The water surface in square feet, which you get by multiplying length by width. If you're thinking in standard sizes, a 14×28 ft pool is about 390 sq ft, a 16×32 ft pool about 510 sq ft, and a 20×40 ft pool about 800 sq ft. For above-ground round pools, area is roughly the radius squared times 3.14 — a 24-ft round pool is about 450 sq ft. Don't worry about being exact; this drives the size-based portion of the estimate, so a close number is fine for budgeting.
Add-ons: Toggle on the extras you want included. A heater (gas, electric, or heat pump) extends your swim season. A deck or patio is the surround you walk on — concrete, pavers, or stone. A safety fence is required by code in most areas, so budget for it even if it's not optional. An automatic cover is a motorized safety and heat-retention cover, the priciest common add-on. A saltwater system replaces manual chlorine dosing with a salt chlorine generator. Each one adds its typical cost range to the total.
⚠️Special situations▼
My site is sloped, rocky, or hard to access
Site conditions are one of the biggest reasons a real quote exceeds a baseline estimate. A steep slope may need retaining walls, rock or high water tables make excavation far more expensive, and a backyard a digger can't reach may require hand work or even a crane. This tool assumes a relatively standard, accessible site, so if yours is challenging, expect bids toward or above the high end of the range — and ask contractors specifically how your site affects their price.
I'm comparing fiberglass vs. gunite vs. vinyl
Switch the pool type and watch the estimate change — that's the comparison this tool is built for. Beyond upfront cost, weigh the trade-offs: gunite is the most customizable and durable but the most expensive and slowest to build; fiberglass installs in days and is low-maintenance but comes in fixed shapes and sizes; vinyl is the cheapest in-ground option but the liner needs replacing roughly every 7–12 years, an ongoing cost this estimate doesn't include. The cheapest to build isn't always the cheapest to own.
The safety fence seems optional
In most of the U.S., a barrier around a pool is required by code, not a luxury add-on — typically a fence of a minimum height with self-closing, self-latching gates. Some areas also require alarms or a safety cover. Leave the fence toggle on unless you already have compliant fencing, and check your local building department's requirements before you budget. Skipping it can stall your permit and, more importantly, creates a serious safety risk.
I want to know the total cost of ownership, not just to build
This estimator covers installation only. Owning a pool adds real recurring costs: chemicals, electricity for the pump and any heater, water for top-offs, periodic repairs, and eventually a liner replacement (vinyl) or resurfacing (gunite). Many owners spend a few thousand dollars a year to run and maintain a pool. Budget for those alongside the build, and use CalculatedHome's pool heating, filter replacement, and chemical-dosing calculators to estimate the ongoing pieces.
A contractor's quote is far below this range
A bid well under the estimate isn't automatically a bargain — find out why before you sign. Confirm it includes permits, excavation, equipment, electrical, startup, and cleanup, and that it isn't quoting a smaller pool or a lower-grade finish than you expected. Unusually low bids sometimes leave out major line items that reappear as change orders later. Compare the scope line by line against other bids, not just the bottom-line number.
❓Common questions▼
How much does it cost to install a pool?
It depends almost entirely on the type. Above-ground pools often run a few thousand to around fifteen thousand dollars installed, while in-ground pools typically range from the mid-thirties into six figures — vinyl-liner pools are the most affordable in-ground option, fiberglass sits in the middle, and gunite/concrete is the most expensive. Size and add-ons like a heater, deck, and fencing move the number further. Enter your specifics above for a range tailored to the pool you're considering.
Which pool type is cheapest, fiberglass, gunite, or vinyl?
For in-ground pools, vinyl-liner is usually the cheapest to build, gunite the most expensive, and fiberglass in between. But upfront cost isn't the whole story: vinyl liners need replacing every 7–12 years, gunite needs periodic resurfacing, and fiberglass is the lowest-maintenance of the three. Above-ground pools are cheaper than any in-ground type by a wide margin. The best value depends on how long you'll keep the pool and how much maintenance you want to take on.
Why is the estimate such a wide range?
Because pool pricing genuinely varies that much. The same pool can cost 30 to 50 percent more or less depending on your region's labor rates, your site conditions (slope, soil, rock, access), the finishes and equipment you choose, and the contractor. A single number would imply a precision that doesn't exist before a site visit. The low-to-high range reflects what a fair installed cost should fall within, which is more useful for budgeting than a false exact figure.
Does adding a pool increase my property taxes and home value?
Often, yes to both, though the effect varies. An in-ground pool is a permanent improvement that can raise your home's assessed value and therefore your property taxes, and it may increase your homeowners insurance too. Whether it adds resale value depends heavily on your climate and neighborhood — pools tend to add more in warm regions where buyers expect them. This calculator estimates construction cost only; check with your local assessor and insurer for the ongoing impact.
What costs does this estimate leave out?
It covers the pool and the add-ons you select, but not everything a full project involves. Excluded items include landscaping and re-grading beyond the immediate site, the water to fill the pool, electrical-panel upgrades if your service can't handle the equipment, increased property taxes and insurance, and all ongoing maintenance and energy costs. Get these priced separately so your budget reflects the complete picture, not just the build.
