# Free commercial cleaning bid calculator

A monthly bid for an office or a building, from the size, how often you clean, and what you pay. No account. No signup. The math stays in your browser.

The numbers already filled in are starting examples. Change each one to this building, to what you pay, and to the margin you want. They are not industry averages, and they are not a fact about what the work should cost.

The numbers already in the form are starting examples: 10,000 square feet, 5 times a week, $25 an hour of labor cost, 2,000 square feet an hour for the crew, 1 on the crew, 10% for supplies and overhead, and a 20% profit margin. With those examples, time on site is 5 hours on site a visit and paid labor is 5 paid hours with 1 on the crew.; the cost is $137.50 a visit, and the suggested monthly bid is $3,724.07.

Worked from the numbers in the form. Change them and this changes. It is not a quote, and it is not based on a survey of what cleaners charge.

1. 10,000 square feet divided by 2,000 square feet an hour is 5 hours on site on site this visit. Those hours are rounded so you can read them.
2. Labor cost uses paid hours: 5 hours on site on site times 1 on the crew is 5 paid hours with 1 on the crew.. At $25 an hour per cleaner, that pay is $125 of labor. $25 is what you pay one cleaner, not what you charge.
3. Supplies and overhead at 10% of that labor add $12.50. This visit costs $137.50.
4. A 20% profit margin is a share of the price, not an extra 20% on the cost. Divide $137.50 by 0.80. One visit is priced at $171.88.
5. 5 times a week. A year has 52 weeks and 12 months, so multiply the visit price by 5 times 52 divided by 12. The monthly bid is $3,724.07.

This page uses one speed for the whole building, and the same visits every time. A real contract often mixes the work: trash every visit, floors once a week, a heavy job once a quarter. Those need their own times. The monthly number here is a sketch from the numbers you type.

## How a monthly bid is built

Divide the size by how fast the crew cleans together, multiply the time on site by how many cleaners are on the crew, multiply that by what you pay one cleaner per hour, add supplies and overhead if you use them, then set the price so your margin is a share of what you charge. Do that for every visit in the month.

## Questions

**Is this the bid I should send?**

Only if every number in the form is yours. The numbers already filled in are starting examples, not industry averages and not a fact about what the work should cost. Change them. Even then this is one speed for the whole building, not a full spec sheet.

**How is the monthly bid worked out?**

Divide the square feet by how many square feet the crew cleans in an hour. That is the time on site for one visit. Multiply that time by how many cleaners are on the crew to get paid labor hours. The hours shown are rounded so they are easy to read, and the cost uses the full paid hours. Multiply those paid hours by what you pay one cleaner per hour. That is the labor cost. Do not put the rate you charge the customer in that box, because overhead and profit are added after it. If you set a supplies and overhead percent, that percent of the labor cost is added, and the sum is the cost of the visit. Profit margin here is a share of the price, so the visit price is the cost divided by (1 minus the margin). If you come a set number of times a week, a month is that number times 52 divided by 12, because a year has 52 weeks and 12 months. If you come a set number of times a month, the month is that many visits. The monthly bid is the visit price times the visits in a month. Money is rounded to the nearest cent at each step.

**What does profit margin mean here?**

It is a share of the price, not an extra percent added to the cost. A 20% margin means 20 cents of each dollar you charge is profit, and the other 80 cents covers the cost, so the price is the cost divided by 0.80. The 20 in the form is a starting example. Use the margin you actually want.

**What is not included?**

Different tasks at different speeds, restrooms counted by fixture, work that happens only once a month or once a quarter, travel, tax, and anything one number for the whole building cannot see. Supplies and overhead are included only as the percent you type. Leave that percent at 0 and they are left out.

**Can I send this to someone?**

Yes. Copy the link and the same square feet, frequency, crew size, labor cost, and percents open with it. A price you promise a customer should still come from a scope you can stand behind. BlastoClean builds that bid from your areas and your rates and sends it as a link.
