Estimate above-ground and inground pool costs by surface area and shell type, with the extras noted.
Quick answer: A 16 by 32 ft inground pool is about 512 sq ft of surface. At the calculator's fiberglass preset of roughly $105 per square foot that is about $54,000 of shell cost. Decking, fencing, landscaping, heating and equipment commonly add a large amount on top, so plan well above the pool itself.

Concrete pools are fully custom, take the longest to build, and last the longest. Most pool builders quote the shell, equipment, decking and fencing as separate lines — compare bids line by line, not on the headline number.
Volume drives everything else about a pool — chemical doses, filter run time and the water bill. Installation estimates vary enormously by region, access and site work; the shell figure here is a planning range, not a quote.

What is Pool Cost Calculator?
A pool calculator has two jobs: working out how much water the pool holds, and working out what it costs to build. This page covers cost. Inground pools are normally quoted by surface area and shell type, because the shell decides how the pool is built: a vinyl-liner pool uses a panel or concrete wall with a liner, fiberglass uses a molded shell craned into an excavated hole, and concrete or gunite is sprayed and finished on site. Above-ground pools cost a fraction of an inground pool. The surrounding work, decking, fencing, landscaping and equipment, is usually where budgets surprise people.

Shell type decides the cost and the timeline
An above-ground pool is assembled in days and can be removed later. Inground vinyl is the cheapest inground route, with a panel or concrete wall and a liner that is replaced periodically. Fiberglass uses a molded shell, which installs quickly but is limited to the shapes and sizes available and needs access for delivery. Concrete or gunite is fully custom, takes the longest and lasts the longest.
The surround is where budgets drift
The pool is only part of the project. Most homeowners also want decking or coping to walk on, a fence that meets local safety rules, lighting, a heater, a cover and space for equipment. Excavation access matters too: if a machine cannot reach the back garden, everything is carried, and that shows up in labor. Landscaping often has to be repaired afterwards.
Permits, fencing and safety rules
Most jurisdictions regulate residential pools, and requirements commonly cover barriers such as fencing or covers, gate hardware, electrical bonding and setback distances from property lines. Rules differ and they change, so confirm the current requirements with your local building department before you buy anything. Build the cost of compliant fencing and any inspection into your budget from the very beginning.
Frequently Asked Questions
How much does an inground pool cost?
Inground pools are typically quoted by surface area and shell type, and the total usually runs into the tens of thousands of dollars before decking, fencing and landscaping. The calculator uses editable per-square-foot presets for above-ground, vinyl, fiberglass and concrete shells so you can see how the options compare.
What is the cheapest type of pool?
An above-ground pool is by far the least expensive, and it can be installed in days rather than months. Among inground options, a vinyl-liner pool is usually the cheapest to build, though the liner itself has to be replaced every so often, which is an ongoing cost that concrete and fiberglass pools do not have.
What costs extra beyond the pool shell?
Almost everything around it: decking or coping, safety fencing, landscaping and irrigation repair, lighting, heating, a cover, pumps and filters, and any electrical work or permits. On many projects these add a substantial amount to the shell price, so budget for them from the start.
What does a pool cost to run?
Ongoing costs include chemicals, electricity for the pump, water for topping up and refilling, and periodic servicing or repairs. Heating can dominate in cooler climates. Opening and closing the pool each year is another recurring cost, and equipment replacement appears every few years.
