Commercial Cleaning Bid Calculator: The Equipment Cost Math Nobody Teaches New Companies

The Short Answer

To factor equipment cost into a commercial cleaning bid, divide the machine's purchase price by the jobs it will serve over its working life, add that per-job share to the pricing lane, and review the number every time the equipment list or the route changes. The depreciation and the amortization are the two ways to spread the equipment cost, and the calculator habit keeps the bid honest. The machine is a cost per job, not a one-time purchase.

The honest rule is the review. Every new machine changes the per-job number, so the pricing review runs when the equipment list changes, not when the contract expires. The commercial operator who prices the machine into the job keeps the margin where the brochure left it. Run the review monthly, and the surprise dies in the spreadsheet.

The Equipment Cost per Job, Calculated

The bid math starts with a simple division: the purchase price of the machine divided by the jobs it will serve before it is replaced. A backpack vacuum that runs five nights a week serves more jobs in a year than the spare machine that waits in the closet, so the per-job share follows the route hours. The per-job cost is the purchase price divided by the jobs, and the route sets the denominator. The machine earns its keep one job at a time.

Depreciation is the value the machine loses as it works, and it is the hidden line of the equipment cost story. The commercial operator who ignores depreciation sees the machine as paid off on day one, and the operator who tracks it sees the replacement coming before the breakdown. Depreciation is the clock on the machine, and the bid has to hear it tick. The breakdown is the bill for the depreciation nobody priced.

Amortization spreads the equipment cost across the period that uses it, which is the honest way to match the machine to the commercial contract. The carpet extractor bought for one contract gets amortized across that contract, and the floor scrubber that serves every route gets amortized across the whole book of work. Amortization matches the cost period to the work period. One contract pays for the extractor. The route book pays for the scrubber.

The Pricing Formula for the Bid

The calculator habit is the discipline that turns the equipment cost into a pricing number instead of a guess: the purchase price, the expected jobs, the per-job share, and the review date all live on the same page. The commercial operator who runs the calculator on every new machine keeps the bid book consistent. The calculator is the cheapest equipment the company owns. A minute of division beats a quarter of margin loss.

The commercial job review is where the per-job math meets the real route: the jobs per week, the hours per job, and the machines each job touches. The equipment cost per job rises when the route shrinks and falls when it grows, which is why the review runs on a schedule. Re-run the per-job math every time the route count changes. The number is only honest on the day you recalculate it.

• Purchase price: divided by the expected jobs
• Depreciation: the value the machine loses
• Per-job cost: the share that belongs in the bid
• Amortization: the cost matched to the work period

What This Means for Your Operation

Run the per-job division before you quote the next contract. Depreciation and amortization spread the machine cost across the work it serves, and the per-job share belongs in every bid. The startup cost guide carries the equipment lane into the full launch budget.
