How it works
How this tool works.
Rent per square foot is the simplest way to compare units that aren’t the same size. A larger unit almost always rents for more in total, but not always more per square foot — and that per-foot figure is what tells you whether a rent is aggressive or soft relative to the space.
Enter the monthly rent and the living area, and this calculator returns rent per square foot for the month and the year. It’s arithmetic on your inputs, most useful comparing similar units in the same market.
Enter the unit’s monthly rent.
Enter the living area in square feet.
The tool divides rent by area for the monthly figure, then multiplies by 12 for the annual figure.
Compare units measured the same way to judge whether a rent is high or low for the space.
Make the result useful
rent density
This worksheet makes rent density explicit from the exact figures you enter. Review the period and basis of every amount before comparing results.
Use a conservative scenario as well as the base scenario; the calculation describes assumptions rather than predicting behavior.
The assumptions that move this result
Rent
Recurring monthly rent.
Square feet
Comparable documented living area.
monthly rent ÷ documented square feet
Read the result as a planning measure for the selected period.
Read the number in context
Worked scenario
$1,800 ÷ 900 sq ft = $2.00/sq ft.
Edge case
Different utility packages can make a comp misleading.
It does not determine market or lawful rent.
Before you act
• Confirm every input uses the same time period.
• Test a downside scenario before relying on the result.
• Keep source records with the decision.
Formula
monthly rent ÷ documented square feet
What period should I use?
Use one consistent reporting or planning period for every input.
Does this predict performance?
No. It only performs the stated arithmetic.
Can it replace records or advice?
No. Confirm decisions with source records and appropriate professional guidance.
