Pricing by square foot sounds simple. Multiply a number, send a quote, move on… right?
Well, no. In practice, calculating cleaning costs *only* by square foot is one the easiest ways to misprice a job if you don’t understand what’s actually driving the number. 

While knowing your cost per square foot is part of it, square footage doesn’t create cost. Labor does. Here, we’ll walk through how to calculate cleaning cost per square foot (the RIGHT way) step by step. 

Quick answer

Cleaning cost per square foot is calculated by dividing the total cost of a cleaning job by the total cleanable square footage. The accuracy depends entirely on how well labor time and labor costs are calculated.

How Cleaning Cost Per Square Foot Is Calculated

Cleaning cost per square foot is calculated by dividing the total cost of a cleaning job by the total cleanable square footage.

Formula:
(Total Job Cost) ÷ (Total Square Footage) = (Cost per Square Foot)

That’s the simple math. But the part that trips people up is what comes before it.

Cost per square foot is a conversion, not a starting point. It only works if the total job cost is grounded in reality. When pricing goes wrong, it’s rarely because of the formula itself. It’s because the inputs were guessed, rushed, or incomplete.

Step 1: Calculate Your Labor Cost (*Don’t Skip This Step!*)

Everything flows from your labor cost. If this number is off, every number after it will be too.

Before square footage ever enters the picture, you need a clear view of what it actually costs to run a job. For most cleaning businesses, labor is the single biggest driver of price.

At a minimum, your labor cost should include:

• Cleaner pay
• Payroll taxes or contractor costs
• Cleaning supplies
• Travel time between jobs
• Insurance
• Overhead like admin time, software, and vehicles
• Your profit margin

If your labor cost is underestimated, your cost per square foot will be too. Every time. There’s no formula that fixes that later.

Step 2: Estimate How Long the Space Takes to Clean

Once labor cost is clear, time becomes the next variable.

This is where production rates come in.

A production rate is simply how many square feet your team can clean per hour under normal conditions. It’s not a guess and it’s not universal. It’s an estimate based on real work.

Production rates can change based on:

• Type of space
• Cleaning frequency
• Surface types
• Number of bathrooms
• Foot traffic and overall use

Because of that, there is no single “correct” number, which is why you can’t copy and paste your numbers from another cleaning company. There are ranges.

As rough benchmarks for commercial cleaning, many businesses see:

• Light commercial cleaning at about 1,000 to 1,500 square feet per labor hour
• Heavier-use spaces at about 500 to 1,000 square feet per labor hour

These are just reference points, though. A medical office, a gym, and a quiet office suite can all be the same size and require very different amounts of time.

Step 3: Convert Labor Cost Into Cost Per Square Foot

Once you know labor cost and time, the math is pretty straightforward.

Here’s a simple example:

• Space size: 5,000 square feet
• Estimated labor time: 4 hours
• All-in labor cost: $40 per hour
• Total job cost: $160

To calculate the cleaning cost per square foot:
$160 ÷ 5,000 sq ft = $0.032 per square foot

That’s the number clients see and compare. It works because the labor math came first.

This approach is most useful for repeatable spaces with a consistent scope. When the space, frequency, and expectations stay stable, cost per square foot can be a clear way to express pricing. When they don’t, the number starts to hide more than it explains.

Typical Cleaning Cost Per Square Foot

This is the section most people scroll to first, but please make sure you don’t skip the part that comes before this!

For commercial cleaning, cost per square foot is usually discussed in ranges, not fixed prices. Those ranges reflect differences in labor costs, space usage, and service expectations.

Common reference ranges include:

• Basic commercial cleaning: $0.03 to $0.07 per square foot
• Higher-touch facilities: $0.07 to $0.15 or more per square foot

Actual rates vary by location, labor costs, and scope of work.

These numbers are best used as a reality check. If your calculated rate falls far outside these ranges, it’s usually a sign to revisit labor costs or time estimates before sending a quote.

When Cost Per Square Foot Works Best

Cost per square foot works best when the work behaves the same way visit after visit.

It’s usually a good fit when you have:

• A consistent space
• A fixed scope of work
• A predictable cleaning frequency
• Known production rates

This is why square-foot pricing shows up most often in:

• Offices
• Medical facilities
• Gyms
• Retail locations

In these environments, consistency makes time easier to estimate and pricing easier to standardize.

If you want deeper context on where this method holds up and where it creates problems, Square-Foot Cleaning Rates Are Failing You explores those tradeoffs in more detail.

When Cost Per Square Foot Breaks Down

Square-foot pricing becomes unreliable when conditions change from job to job.

This is most common in:

• Residential cleaning
• First-time deep cleans
• Homes with pets, clutter, or shifting priorities

Two homes can be the same size and require completely different amounts of labor.

Square footage tells you how big a space is. It does not tell you how hard it is to clean.

When effort varies, pricing that leans too heavily on square footage tends to undercharge, overpromise, or create scheduling problems down the line. 

How Most Profitable Cleaning Businesses Use Square Footage

Most experienced cleaning businesses don’t treat square footage as the primary pricing driver.

Instead, they use it as:

• A starting estimate
• A sanity check against labor hours
• A way to standardize pricing for repeatable spaces

Labor time stays constant. Square footage helps translate that labor into a number clients recognize, but it doesn’t replace time-based thinking.

Final Thoughts

Cost per square foot is a helpful way to express pricing, not a reliable way to create it.

When it’s grounded in real labor costs and realistic time estimates, it can work well for consistent, repeatable spaces. When it isn’t, it tends to hide problems instead of solving them.

Start with labor. Use square footage to translate that work into a number clients understand. That’s how pricing stays accurate as your business grows.

Frequently Asked Questions

How do you calculate cleaning cost per square foot?
Divide the total cost of the job by the total cleanable square footage. The accuracy depends on how well labor time and costs are estimated.

What is a good cleaning price per square foot?
For commercial cleaning, many businesses fall between $0.03 and $0.15 per square foot, depending on space type, frequency, and labor costs.

Is square-foot pricing good for cleaning businesses?
It can work well for repeatable commercial spaces with a fixed scope. It is less reliable for residential or highly variable jobs.

Should residential cleaners charge by square footage?
In most cases, no. Residential homes vary too much in condition and priorities for square footage alone to reflect effort accurately.

Is cost per square foot better for commercial cleaning?
Yes. It’s more commonly used in commercial settings because spaces and scopes tend to be more consistent from visit to visit.
