If you are in the floor cleaning business, you need to know how much you are charging per square foot. This will allow you to be consistent in your pricing for each job completed and not short change you or the customer. For example, say your first cleaning job paid £390 for cleaning a 2,000-square-foot floor 20 times a month. This is a total of 2,000 x 20 square feet or 40,000 square feet. You should determine how much you were paid per square foot, so on your next job you know what to charge.

Divide the total number amount of money received by the total square feet cleaned. Using the above example, this amounts to £390/40,000 square feet, which is 01 per square foot.

Determine the price for a new example client who wants a 3,000-square-foot floor cleaned 15 times a month.

Find the total square feet cleaned per month by multiplying the floor area by the times cleaned per month. This gives 3,000 square feet x 15 or 45,000 square feet.

Multiply the total square feet to be cleaned by your price per square foot to obtain the total price to charge the client. Continuing the example, you have 45,000 x 0.015, which is £438.
