Day Porter vs Night Crew: What Each One Really Costs Per Month

A day porter costs more per hour than a night cleaner and covers far less ground, so on the same building a porter is an addition to the night crew rather than a substitute for it. On a 60,000 sq ft office, four porter hours a day adds roughly $2,860 a month to a night-cleaning contract worth about $9,540. That is a 30% increase, and the client has to see 30% of value for it.

This article works both numbers end to end, using the production rates and cost assumptions inside the taskforse bid calculator, so you can put a porter line on your next bid and defend it.

Key takeaways

• A half-day porter (4 hours, 5 days) is 86.6 billed hours a month, once weeks are counted at 4.33 per month.
• At a $17.25 wage with 25% burden, loaded cost is $21.56 an hour, and at a 25% margin with 13% supplies the billed rate is about $33 an hour.
• Night cleaning on 60,000 sq ft of general office at 4,500 sq ft per hour is 13.3 hours a visit, 288.8 hours a month at five nights a week.
• Replacing a night crew with porters costs more, not less, because daytime work is slower around occupants.
• A solo porter is a single point of failure: BLS puts the 2025 absence rate in cleaning and maintenance occupations at 3.4%, and a missing porter is visible to the client in a way a missing night cleaner is not.

What does a day porter actually cost per month?

Start with the only number that matters: hours of presence. A porter is not priced by square footage, because you are not buying coverage of an area, you are buying somebody being there.

Four hours a day, five days a week, is 20 hours a week. Multiply by 4.33 weeks and you get 86.6 hours a month. Eight hours a day doubles that to 173.2.

Now cost those hours. The U.S. Bureau of Labor Statistics puts the median wage for janitors and building cleaners at $17.71 an hour as of May 2025, with the bottom 10% under $13.77 and the top 10% over $24.17. The taskforse calculator prefills $17.25 for the US market and expects you to replace it with your own payroll number.

On top of the wage sits burden: payroll taxes, workers' compensation, and whatever benefits you carry. The calculator defaults to 25%, with 15% and 35% as the other presets. That is in line with the national picture: BLS reports that for private industry workers in June 2026, benefits were 30.0% of total compensation, at $14.07 an hour against $32.82 in wages.

Line	Half-day porter (4 hrs × 5 days)	Full-day porter (8 hrs × 5 days)
Billed hours per month	86.6	173.2
Loaded cost per hour ($17.25 + 25%)	$21.56	$21.56
Labor cost per month	$1,867	$3,734
Sell price at 25% margin	$2,489	$4,978
With supplies at 13% of price	$2,861	$5,722
Effective billed rate per hour	$33.04	$33.04

That $33 an hour is the number to sanity check against your market. If your competitors are quoting porter coverage at $25, one of two things is true: their wage is lower than yours, or they are selling the hour at a margin that will not survive a workers' comp renewal.

What does the night crew cost for the same building?

Night work is priced the way the rest of your bids are priced: area divided by a production rate. In taskforse, general office runs at 5,500 sq ft per hour at value service, 4,500 at medium, and 3,500 at premium. Those are Neil Lathangue's figures, reviewed in August 2026 from thirty years of buying and running this work, not a published standard.

Take the same 60,000 sq ft office at medium service:

• 60,000 ÷ 4,500 = 13.3 labor hours per visit
• 13.3 × 5 nights = 66.7 hours a week
• 66.7 × 4.33 = 288.8 hours a month
• 288.8 × $21.56 loaded = $6,227 labor
• At 25% margin: $8,303. With supplies at 13% of price: $9,544 a month

That works out to $1.91 per sq ft per year, or about $0.16 per sq ft per month, which sits inside the ordinary band for recurring office work. The full method, including restroom fixture counts and floor-type modifiers, is in how to bid a commercial cleaning contract.

Put the two side by side and the shape of the decision is clear:

	Night crew	Half-day porter	Both
Monthly hours	288.8	86.6	375.4
Monthly price	$9,544	$2,861	$12,405
Price per sq ft per year	$1.91	$0.57	$2.48
What the client sees	A clean building at 8am	A person, all day	Both

Should a day porter replace the night crew?

For most buildings, no, and the math is the reason.

To clean 60,000 sq ft during the day you still need the same 13.3 hours of cleaning, except those hours are now worked around people. Desks are occupied, restrooms are in use, the lobby has traffic through it, and the porter stops mid-task every time somebody needs something. Plan on 15% to 25% slower than your night rate: that is an operator rule of thumb, not a measured standard, and you should validate it against your own timesheets before you bid on it.

At 20% slower, your effective daytime rate on general office drops from 4,500 to about 3,600 sq ft an hour, and the same building needs 16.7 hours a day instead of 13.3. Two porters at eight hours is 346.4 hours a month against the night crew's 288.8. You would be buying 20% more labor to do the same scope, in front of an audience.

Where porters do replace night crews is where the building cannot be cleaned empty: some schools, 24-hour facilities, secure sites where after-hours access is a problem, and buildings whose tenants will not accept cleaners in their space unsupervised. In those cases the extra hours are not optional, and the bid has to carry them openly.

Why do clients pay for a porter at all?

Because the thing a porter sells is not cleanliness, it is visibility.

Night cleaning is invisible by design. Twenty good nights leave no trace, and the only evidence your client ever gets is the occasional complaint. A porter inverts that: the client's staff see someone in the building every day, the spilled coffee in reception is gone in ten minutes instead of fourteen hours, and the restroom that runs out of towels at 11am gets restocked at 11am.

That is also the argument to make when the porter line comes under budget pressure. A porter is the cheapest renewal insurance on the contract, and renewals are where the money is: the same logic runs through how to keep a cleaning contract at renewal.

What happens the day the porter calls off?

This is the part most bids ignore, and it is the single biggest operational difference between the two crews.

A night crew of six who shows up five is short-handed, and the work absorbs it: routes get stretched, a detail task slips a week, and the client usually never knows. A porter is one person. When that person calls off, the coverage the client is paying $2,861 a month for is simply not there, in a lobby, in daylight, in front of the people who sign the renewal.

BLS data puts the 2025 absence rate for building and grounds cleaning and maintenance occupations at 3.4% of scheduled work time, against 3.2% across all occupations. The 2025 figure is an eleven-month average that excludes October. On a 21-day working month, 3.4% is roughly two thirds of a day: call it one missed porter day every six weeks, per porter, as a planning number.

So a porter contract needs a named backup before it starts, not a phone call on the morning. One cross-trained night cleaner who can work days, or a floater across two nearby accounts, is the difference between a gap the client never notices and a gap that becomes the first line of the renewal meeting. We wrote up the mechanics in building a callout chain that covers a night shift, and the cost of getting it wrong in what a single no-show actually costs.

How should the porter line appear on the bid?

On the same contract, on its own line, with the hours written out.

Bury a porter inside a single monthly cleaning figure and two things happen. The price looks high against competitors who quoted night work only, and when the client's budget gets cut you lose the argument about what to remove, because nobody can see what anything costs.

Write it as: night cleaning, five nights, $9,544 a month. Day porter, Monday to Friday, 7am to 11am, $2,861 a month. Now the client is making a choice between two visible things instead of pushing back on one opaque number, and if they drop the porter you keep the account at $9,544 rather than losing it at $12,405.

taskforse is building the software that prices work this way: production rates, loaded labor and coverage on separate lines, so a porter is a number you can defend rather than a guess buried in a monthly total. If that sounds like the bid you wish you had last month, join the waitlist.
