Rent per Square Foot Calculator

The calculator divides monthly rent by floor area. Enter the area in m²; the highlighted U.S. result is per square foot (about 4.65 per ft² at 2,400 over 48 m², or 50 per m²). Use it to compare listings — not as a market appraisal.

Input

Two fields are enough to start: monthly rent and floor area in m². Utilities, a second listing, income, and people are under More options.

Enter floor area in m². After you fill the field, an approximate square-foot figure appears here.

More options: utilities, listing B, budget

Utilities and fees

This amount is added to rent before the division. Effective rent is rent plus utilities.

Compare listing B

Budget (optional)

The calculator shows effective rent as a share of income and the amount equal to the common 30% housing guideline. That is budgeting advice, not a legal cap.

The calculator divides effective rent by the number of people. Useful for roommates.

Results

Enter rent and area, then click Calculate.

Not a home valuation. The calculator divides rent by area when the floor area is greater than zero. For a percent of property value, use property tax. For rate × area, use rent from area.

The calculator divides monthly rent by floor area in m² when area is greater than zero. At 2,400 and 48 m² the result is 50 per m², about 4.65 per sq ft. At 3,500 and 70 m² it is also 50 per m²; at 1,800 and 45 m² it is 40 per m². For U.S. readers the highlighted figure is per square foot; the per-m² amount stays beside it.

The form starts with two fields: rent and area. The example buttons fill in common pairs. Under More options you can add utilities before the division, compare a second listing, enter monthly income (share of income and the 30% guideline), and enter the number of people (cost per person). After Calculate you also see an area diagram, comparison bars, annual per m² (× 12), and the per-m² figure as a secondary result.

When area is empty or zero, the calculator does not divide by zero and shows a message. It does not appraise the home and does not pull market rates. Two different pairs can share the same ratio, because 2,400 / 48 and 3,500 / 70 are the same proportion. At rent 2,400 and income 8,000 the housing share is exactly 30%.

Property tax multiplies value by a percentage. The rent-from-area calculator goes the other way: it multiplies a per-meter rate by area. Here you divide rent by the meters you enter — and you can optionally check how that fits your budget.

Enter 2,400 and 48, click Calculate, and check about 4.65 per sq ft (50 per m²). Then try 1,800 and 45 to see 40 per m². The result is an estimate from division — not a rental offer.

Formula

Model: rent ÷ floor area — not a market appraisal.

When area > 0: result = rent ÷ area. When area ≤ 0, no result is computed.

Optional: effective rent = rent + utilities/fees, then the same ratio. Annual per m² = (rent ÷ area) × 12. Per ft² = per m² ÷ 10.764 (1 m² ≈ 10.764 ft²). Income share = effective rent ÷ income × 100%. 30% guideline = income × 0.30. Per person = effective rent ÷ people.

How to use

  1. Enter monthly rent, for example 2,400.
  2. Enter floor area in m², for example 48.
  3. Optionally open More options: utilities, listing B, income, or people.
  4. Click Calculate. At 2,400 and 48 the per-m² result is 50 (about 4.65 per sq ft); at 1,800 and 45 it is 40 per m².
  5. Use property tax for a percent of value; use rent from area for rate × meters.

Rent, area, and ratio

Result = rent ÷ area when meters are greater than zero. 2,400 over 48 m² gives 50 per m² (about 4.65 per sq ft).

rent
Monthly amount in the first field. 2,400 ÷ 48 gives 50 per m².
area
Divisor in m². At 3,500 over 70 m² the result is also 50; at 1,800 over 45 m² it is 40.
utilities/fees
Optional amount added to rent before the division.
income
Optional gross monthly income. At 2,400 rent and 8,000 income the share is 30%.
people
Optional number of people. At 2,400 rent and 2 people the amount per person is 1,200.
result
The ratio in the selected currency. On this English page the highlighted figure is per sq ft.

Which tool to use

  1. This page — rent ÷ m² (compare rental listings).
  2. Rent from area — rate × area (+ utilities).
  3. Property tax — value × percentage rate.

Examples

Example 1

  • Rent: 2,400
  • Area: 48 m²

≈ 4.65 per sq ft (50 per m²)

2,400 ÷ 48 = 50 per m² ≈ 4.65 per ft².

Example 2

  • Rent: 3,500
  • Area: 70 m²

50 per m²

3,500 ÷ 70 = 50 — same ratio, different pair.

Example 3

  • Rent: 1,800
  • Area: 45 m²

40 per m²

1,800 ÷ 45 = 40.

Example 4

  • Rent: 2,400
  • Utilities/fees: 300
  • Area: 48 m²

56.25 per m²

(2,400 + 300) ÷ 48 = 56.25 — effective rent.

Example 5

  • Rent: 2,400
  • Area: 48 m²
  • Income: 8,000
  • People: 2

50 per m² · 30% of income · 1,200 per person

2,400 ÷ 48 = 50; 2,400 ÷ 8,000 = 30%; 2,400 ÷ 2 = 1,200.

Common questions

How does rent per area work on this page?

The calculator divides monthly rent by floor area in m² when area is greater than zero. At 2,400 and 48 m² the result is 50 per m², about 4.65 per sq ft in the header currency. This English page highlights per square foot; per m² stays as a secondary figure.

Is the result a market rental offer?

No. It is a ratio from the numbers you enter. Listings, location, and admin fees can produce a different rate — this page does not check them.

Do utilities and admin fees count in the rent field?

The main rent field does not split components. For base rent only, leave fees out. The optional utilities field adds them to rent before the division when you fill it in.

What if area is 0 or empty?

The calculator shows a message on the area field. It does not divide by zero — without a positive area there is no meaningful ratio.

Does the calculator show annual rent per area?

The main result is the monthly ratio. A separate figure shows the per-m² ratio multiplied by 12 — an annual orientation only, without changing the formula and without market data.

How is this different from a property-tax calculator?

Property tax usually multiplies value by a percentage rate. Here the result is rent divided by floor area.

How is this different from rent-from-area (rate × area)?

This page divides rent by area. The rent-from-area calculator goes the other way: it multiplies a per-m² rate by area and may add utilities. Those are two different formulas.

Why calculate rent per square foot or per m²?

To compare listings of different sizes with one number. A smaller flat can look cheaper in total rent but cost more per unit of area — the ratio shows that. U.S. listings often quote dollars per sq ft.

Does a comma in the area, such as 48,5, work?

Yes. 48.5 and 48,5 mean the same area. Do not enter thousand separators inside the field.

Does the header currency change the numeric result?

No. The header only labels amounts in the selected currency. 2,400 ÷ 48 still gives 50 per m².

What does the monthly income field do?

When you enter income, the calculator shows effective rent as a share of that income and the amount equal to 30%. At 2,400 rent and 8,000 income the share is 30%. That follows the common U.S. housing cost-burden guideline, not a legal rent cap.

What does the people field do?

The calculator divides effective rent by the number of people. At 2,400 and 2 people the per-person amount is 1,200. The field does not change the per-area ratio.

· Hubert Ligocki

At 2,400 and 48 m² the result is 50; at 1,800 and 45 m² the result is 40.

Knowledge sources

Rent per area is a plain arithmetic ratio. The 30% housing guideline is a common U.S. research threshold, not a statutory rent cap.
