Rent Per Sq Ft Calculator

Calculate rent per square foot from monthly rent and space size, or find the monthly and annual rent from a price per square foot.

Calculator Functions

Function	What it does	What it requires
Rent per square foot	Finds the rent rate per square foot, per year and per month, from the rent paid for a space	Requires the monthly rent in dollars and the space area
Monthly rent	Finds the monthly rent for a space quoted at a rate per square foot	Requires the space area and the rent rate per square foot, per year or per month
Space area	Finds the area that a monthly rent pays for at a given rate per square foot	Requires the monthly rent in dollars and the rent rate per square foot, per year or per month

The space area can be entered in square feet, square meters or square yards, and the rate in dollars per square foot per year or per month. Every result lists the monthly rent, the annual rent, the monthly and annual rates, the area in square feet and square meters, and the rent per square meter per month. Amounts are in US dollars with no currency conversion.

Rent Per Sq Ft Formulas

Rent per square foot

The monthly rent is divided by the area, and the headline result is that rate multiplied by 12. A space of 1,200 ft² renting for $1,800 a month costs 1,800 ÷ 1,200 = $1.50 per ft² per month, or $18 per ft² per year. An area in other units is converted first, with 1 m² = 10.7639 ft² and 1 yd² = 9 ft² [1]. A 100 m² space at $2,000 a month is 1,076.39 ft², which gives $22.30 per ft² per year and $20 per m² per month.

Monthly rent

R_year is the rate per square foot per year. A 1,500 ft² building at $18 per ft² per year rents for 1,500 × 18 ÷ 12 = $2,250 a month, or $27,000 a year. When the rate is entered per month the division by 12 is skipped: 1,000 ft² at $1.25 per ft² per month is $1,250 a month.

Space area

This is the same relationship solved for area. A budget of $2,250 a month at $18 per ft² per year pays for 2,250 × 12 ÷ 18 = 1,500 ft². A rate of zero is rejected, because no area can be found from it.

How to Calculate Rent Per Square Foot

Divide the rent by the square footage. Rent for one month gives a monthly rate, and rent for a full year gives an annual rate, so $1,800 a month for 1,200 ft² is $1.50 per ft² per month and $21,600 ÷ 1,200 = $18 per ft² per year. Multiply a monthly rate by 12 to compare it with a rate quoted per year, or divide an annual rate by 12 to compare it with a monthly one.

Limits of This Estimate

• The rate covers only the rent entered. Utilities, taxes, insurance, maintenance charges and other fees billed separately are not part of it unless they are added to the monthly rent first.
• The result depends on which area is used. A lease can state usable area or a larger rentable area that includes a share of common space, and the two give different rates for the same rent.
• The annual figures are 12 times the monthly ones. Rent increases, free months and other changes during a lease are not modeled.
