Price Per Sqft Calculator

Background.

Two houses listed at $450,000 and $540,000 tell you little until you know what each one buys. Divide by floor area and the first, at 1,800 square feet, costs $250 a square foot; the second, at 2,400, costs $225. The dearer house is the cheaper one per foot. That is the comparison price per square foot exists to make, and also a hint at why it needs care.

Larger homes nearly always come out cheaper per square foot, because much of what a house costs does not grow with its size. The plot, the kitchen, the bathrooms and the connections to water and power are paid for once whether the rooms around them are generous or tight. A small flat at a high rate and a big house at a low one can both be fairly priced, so the useful comparison is between homes of similar size, age and condition in the same area.

The other trap is the area itself. The rate is only as good as the floor-area figure you divide by, and listings do not all measure the same way: some quote finished living space only, some fold in a basement or an enclosed porch, and apartment markets differ on whether shared areas count. Counting 150 fewer square feet on that 1,800-square-foot home raises its rate from $250 to $272.73.

Outside the United States, property is usually priced per square metre. One square metre is 10.7639 square feet, so the page converts the area once and reports both rates. Land area, taxes, agent fees and closing costs play no part; the inputs are the headline price and the floor area.

What is price per sqft calculator?

Price per square foot is a property's asking or sale price divided by its floor area in square feet; price per square metre is the same idea with metric area. It is a unit price, like a cost per kilogram at a market stall, used to compare homes of different sizes and to sanity-check an asking price against recent nearby sales. It describes the headline price only, not everything the purchase will finally cost.

How to use this calculator.

1. 01Enter the total property price in dollars — the listing price, your offer, or a recorded sale price. Leave out closing costs, taxes and agent fees so the rate compares cleanly with other listings.
2. 02Enter the floor area from the listing, appraisal or plans, and check what it covers. Finished living area is the usual basis for houses; adding a garage or unfinished basement drags the rate down.
3. 03Choose square feet or square metres to match the area you entered. The rate in the other unit is worked out for you.
4. 04Compare the result with recent sales of similar-sized homes nearby rather than a citywide average that mixes small flats with large houses.

The formula.

Price per square foot = total price ÷ floor area in square feet, and price per square metre = total price ÷ floor area in square metres. Only one area is entered, so the other comes from the exact definition of the foot: one foot is 0.3048 m, one square foot is 0.09290304 m², and one square metre is therefore 10.7639104167 square feet. An area in square metres is multiplied by that factor to get square feet; an area in square feet is divided by it to get square metres. As a result the per-metre rate is always 10.7639 times the per-foot rate. Because area sits in the denominator, the answer is more sensitive to the floor-area figure than people expect, and a measurement dispute of a few hundred square feet can move it by tens of dollars. The area must be greater than zero; a price of zero simply returns zero.
