Is this monthly or annual?

Enter monthly rent. The calculator shows $/sq ft per month and per year, plus total annual rent.

Does it include utilities or NNN/CAM?

No. Add those charges to rent first if you want all-in $/sq ft.

What if the listing quotes $/sq ft per year?

Multiply by the square footage to get annual rent, divide by 12 for monthly rent, then enter that here.

Usable vs rentable square feet?

Use the same basis across the options you compare. Commercial spaces often use rentable square feet; stay consistent.

Can I compare furnished vs unfurnished?

Yes, but consider utility differences and included services separately—this calculator just normalizes rent to area.

Is $/sq ft usually quoted annually?

In commercial leasing, yes—$/sq ft is usually an annual rate. Residential listings usually quote monthly rent, which this calculator converts into both monthly and annual $/sq ft.

What is rentable vs usable square feet?

Usable square feet are the area you can actually occupy. Rentable square feet include a share of common areas. Always confirm which measurement your lease uses before comparing $/sq ft.

How do I handle free rent or concessions?

Convert the concession into an effective monthly rent (total rent paid over the term divided by months) and then use that figure so your $/sq ft reflects true occupancy cost.

Rent per Square Foot Calculator

Find monthly and annual rent per square foot to compare leases, units, or buildings quickly.

Results

Rent per sq ft (monthly): $2 /sq ft
Rent per sq ft (annual): $25 /sq ft
Annual rent: $30,000

Overview

Landlords, brokers, and listing sites all talk about rent per square foot, but they don’t always use the same units or include the same costs. A $2,500 1‑bed and a $3,200 2‑bed can feel hard to compare until you normalize both to a simple $/sq ft number.

This rent per square foot calculator does that normalization for you. You enter monthly rent and square footage, and it returns rent per square foot per month and per year, plus total annual rent. That lets you compare apartments, offices, or retail spaces on an apples‑to‑apples basis before you dig into the finer print like NNN, CAM, or utilities.

You can also work backward from a budget or target $/sq ft: if you know your top‑end rent or the market rate per square foot, it’s easy to test how different unit sizes or layouts fit within your budget. That makes this tool useful not just for evaluating listings, but for planning moves, negotiating renewals, and sanity‑checking rent numbers in pro formas and pitch decks.

Commercial listings often quote $/sq ft on an annual basis and may use different measurement standards (rentable vs usable square feet). This calculator keeps the math consistent, but you still need to confirm whether the quoted rent is base rent only or includes operating expenses, taxes, and common area maintenance so you are comparing true occupancy cost. For team searches, a consistent $/sq ft view makes it easier to rank options quickly.

How to use this calculator

Enter the monthly rent amount for the unit, suite, or building space you’re evaluating.
Enter the square footage of the space, using the same basis (rentable, usable, or gross) that the listing or lease uses.
Review the monthly $/sq ft output to compare against other listings or market benchmarks.
Check the annual $/sq ft and total annual rent if you need a yearly view for budgeting or pro forma analysis.
Repeat for each option you’re considering, then line up the results to see which spaces are relatively expensive or cheap per square foot.

Inputs explained

Monthly rent: The total monthly rent you pay or are quoted for the space. For commercial leases that quote annual rent, divide by 12 first to convert to a monthly figure before entering it.
Square footage: The interior area of the unit in square feet. Use the same measurement basis across all comparisons—rentable square feet for commercial spaces or interior living area for residential units.

Outputs explained

Rent per sq ft (monthly): Monthly rent divided by square footage. This is useful for comparing residential units or any listing that quotes monthly rent.
Rent per sq ft (annual): Annualized rent per square foot, commonly used in commercial leasing. It is calculated as (Monthly rent × 12) ÷ Square feet.
Annual rent: Total rent for a full year based on the monthly rent input, before adding any operating expenses, taxes, or common area charges.

How it works

You provide monthly rent and total square footage for the unit or space. Monthly rent per square foot is computed as Monthly rent ÷ Square feet.

To get an annualized view, we multiply monthly rent by 12 to get annual rent and then divide by square feet to produce Annual $/sq ft = (Monthly rent × 12) ÷ Square feet.

The calculator reports all three outputs: monthly $/sq ft, annual $/sq ft, and total annual rent, so you can match whichever format a landlord, broker, or market report uses.

Because the math is linear, you can use it both ways: either start from rent to get $/sq ft, or start from a target $/sq ft and square footage (by rearranging the formula) to back into a budgeted rent.

All calculations assume you’re using the same square footage basis (rentable vs usable) across the options you compare, which is key for meaningful comparisons.

If your lease quote is already annual $/sq ft, multiply by square footage to get annual rent and divide by 12 to enter a monthly rent equivalent.

Formula

Monthly $/sq ft = Monthly rent ÷ Square feet
Annual $/sq ft = (Monthly rent × 12) ÷ Square feet
Annual rent = Monthly rent × 12

When to use it

Comparing multiple apartments or commercial suites that differ in both size and rent to see which offers better value per square foot.
Checking whether a proposed lease rate is in line with market $/sq ft norms for a neighborhood or building class.
Normalizing rents in a pitch deck or client memo so stakeholders can compare options quickly at a glance.
Evaluating whether a smaller but more expensive unit actually costs more per square foot than a larger, seemingly pricier one.
Roughly sizing a budget: starting from a target $/sq ft and known square footage, you can infer what monthly rent would look like.
Comparing renewal offers year over year by converting both leases into annual $/sq ft.
Estimating occupancy costs for expansion planning by testing different unit sizes at a target $/sq ft.
Normalizing mixed‑use space options (office vs retail vs flex) into a single metric for a quick first‑pass screen.

Tips & cautions

Keep units consistent—always compare monthly rent and square feet on the same basis (rentable vs usable vs gross). Mixing bases will give misleading $/sq ft results.
For annual leases quoted in $/sq ft per year, you can multiply that figure by square feet to get annual rent, divide by 12 for monthly rent, and then feed that into this calculator.
Commercial listings sometimes quote “face rent” that excludes concessions or free months; adjust monthly rent to reflect effective rent if you want a true $/sq ft comparison.
If utilities, parking, or NNN/CAM charges differ significantly between options, consider adding those costs into the monthly rent input so your $/sq ft figure reflects more of your real monthly spend.
Use the annual $/sq ft output when comparing to market reports, which often quote commercial rents on a per‑year per‑square‑foot basis.
When comparing across cities or submarkets, pair $/sq ft values with qualitative factors like commute, amenities, and building quality so you do not chase price alone.
Confirm whether the listing uses rentable, usable, or gross square feet, and keep that measurement standard consistent across your comparisons.
Ignores utilities, NNN, CAM, parking, concessions, or build‑out costs by default—these can substantially change effective occupancy cost.
Assumes the square footage basis (rentable vs usable vs gross) is consistent across the units you compare; if not, adjust or normalize first.
Does not model rent escalations, step‑ups, or percentage rent; use the base‑year rate here for quick checks and handle escalations in a separate cash‑flow model.
Does not factor in qualitative differences (light, layout, amenities, location) that may justify higher or lower $/sq ft.
Treats rent as flat; triple‑net or modified‑gross arrangements with variable operating expenses are outside the scope of this simple calculator.
Does not adjust for rent concessions, free months, or tenant improvement allowances unless you manually incorporate those into the rent input.

Worked examples

$2,500 rent, 1,200 sq ft

Monthly $/sq ft ≈ $2.08
Annual $/sq ft ≈ $24.99
Annual rent = $30,000

$3,200 rent, 950 sq ft

Monthly $/sq ft ≈ $3.37
Annual $/sq ft ≈ $40.42
Annual rent = $38,400

$25 per sq ft per year for 2,000 sq ft

Annual rent = 25 × 2,000 = $50,000.
Monthly rent = 50,000 ÷ 12 ≈ $4,167.
Monthly $/sq ft ≈ $2.08; annual $/sq ft stays $25.

$1,800 rent, 850 sq ft

Monthly $/sq ft ≈ $2.12
Annual $/sq ft ≈ $25.41
Annual rent = $21,600

Deep dive

This rent per square foot calculator converts monthly rent and square footage into $/sq ft per month and per year so you can compare apartments, offices, or retail spaces on equal footing.

Use it to normalize different unit sizes and rents, benchmark lease proposals against market rates, or roll up individual spaces into a consistent per‑square‑foot view for budgets and pro formas.

By focusing on a clean $/sq ft metric, the tool helps you spot outliers—spaces that are unusually expensive or cheap for their size—before you layer in more detailed cost items like NNN, CAM, or utilities.

Commercial listings usually quote rent per square foot on an annual basis, while residential listings typically quote monthly rent. This calculator shows both so you can translate between formats without guesswork.

Because measurement standards vary, always confirm whether the square footage is rentable, usable, or gross. Using the same basis across comparisons is the only way to make the $/sq ft metric meaningful.

If you have concessions or free‑rent months, convert those into an effective monthly rent before using the calculator so the $/sq ft figure reflects true occupancy cost.

For lease negotiations, translating rent into $/sq ft helps you compare landlord offers that look different on the surface (for example, lower base rent with higher CAM, or higher base rent with more tenant improvements). It gives you a neutral metric before you model full lease economics.
