Most janitorial contractors cannot tell you, standing in a lobby, the lowest number they will accept for that building. They find out later — usually in the fourth quarter, when the margins on the job they won in March have eaten the margin on the ones they did well.
The walk-away number is not a negotiating position. It is the number below which winning is a loss. Here is how to compute one before you bid, in the order the arithmetic actually runs.
Start from the hours, not the square footage
The fastest way to lose money in this trade is to price off square feet. Two 40,000-square-foot buildings can differ by a factor of three in cleaning hours, and square footage will never tell you which is which.
Build the hour load directly. Walk the building and count what the spec actually asks for: the vacuumed square footage, the fixture counts, the elevators, the stairwells, the number of restrooms and their fixture counts, the trash pulls, the break room square footage, and the entrance mats. Production rates you already have from your own crews — not from a bid calculator — turn each of those into minutes.
Then add the two items contractors habitually forget: periodic work and daytime response. If the schedule calls for a floor scrub twice a week and a restroom burnish monthly, those are hours inside the contract, and they belong in the base rate. If the customer expects someone reachable during business hours, that is labour too.
Convert hours to cost, then to a floor
Take the loaded labor rate you actually pay — wages, payroll taxes at the true rate, workers' compensation at your experience modifier, general liability, paid time off, supervision, recruitment and turnover replacement. If your payroll taxes come off as 7.65%, you are pricing wrong; the statutory burden on a cleaning wage is higher once FUTA, SUTA and local taxes are in it.
Now the fixed layer. Supplies and chemicals per cleaned square foot, equipment replacement reserve, uniforms and linens, vehicle and travel for accounts beyond a five-mile radius, and the software and administration cost of running the account.
Add what the work costs you outside the ticket: the account manager's time on this building, the quarterly inspection, the meeting at the customer's office every month that runs ninety minutes for both of you.
The sum of that, divided by billable hours and divided again by the fraction of scheduled hours you actually deliver — because labour you scheduled but lost to callouts and turnover is real cost — gives you the break-even hourly rate. That is your floor.
Then decide the margin you will not go under
The floor is break-even. The walk-away number sits above it, and the gap is the return your business needs to stay a business: debt service on equipment, the reserve that absorbs a two-month collection delay, the profit that funds the next contract's start-up labour.
A janitorial contract that nets 4% after overhead is not a contract. It is a loan you have extended to the customer, repaid in labour. Operators who price at that level stay in business for a while and then stop, usually when a single large account goes out on rebid and the entire margin of the company goes with it.
Set the walk-away number at the rate that funds that return and no lower. Write it down before the site visit. The reason is behavioural: once you are in the room with the spec, the incumbent's price, and a procurement officer who says the number must come down by 8%, the floor you computed two days earlier is the only thing standing between you and a three-year loss.
Read the contract for the things that move the number
The spec and the contract are different documents, and the contract is where the walk-away number changes.
- Escalator: fixed annual increases preserve margin; a clause indexed to a wage floor only preserves it if the index actually tracks your wage bill.
- Term and notice: a one-year term with sixty days' notice is a fair bet. A three-year term with a fixed price and no exit is a bet on wages, and you should price it as one.
- Frequency changes: who decides them, and at what rate. A customer who can add a weekly floor scrub at the contract rate is a customer who has not agreed to your margin.
- Consumables: if supplies are your cost, make sure the spec does not silently grow them — new restroom dispensers and a switch to a heavier towel.
- Add-ons outside the base: window work, carpet extraction, post-construction. Price them separately so the base rate stays clean.
What a declined bid is worth
The four or five jobs you walk away from each year are not lost revenue. They are the difference between a company that can refinance equipment next spring and one that cannot.
The bid you decline costs you the two hours it took to build. The bid you win at 3% costs you three years of supervision, coverage, and capital, and it teaches the customer what cleaning is worth.
Compute the floor before you walk the space. Write the walk-away number on the front of the file. Then let the arithmetic answer the procurement officer, not your nerves.
