Square footage sets the floor, fixtures set the job
Open floor gets cleaned fast. A vacuum or a mop covers a lot of ground per minute and the rate barely changes between a 900 square foot condo and a 2,400 square foot house. What does not scale that way is the bathroom and the kitchen, which are fixture work: taps, glass, grout, the inside of an oven, the underside of a range hood. Those take the time they take regardless of the floor plan, which is why this calculator treats them as fixed hour adders rather than folding them into the square foot rate.
That is also why per-square-foot pricing misleads people who quote by phone. A 1,200 square foot house with three bathrooms is more work than a 2,000 square foot house with one. Ask for the bathroom count before anything else.
Condition is the biggest single variable and the hardest to ask about
Nobody describes their own house as neglected. The multipliers here — 0.85 for a well kept place through to 1.8 for severe — are the range that separates a job that runs to plan from one that ruins a day. The way to get an honest answer is to ask about specifics instead of asking for a grade: when was it last cleaned professionally, are there pets, is there clutter on the floors and counters that has to be moved before anything can be wiped, and is anyone smoking indoors. Clutter in particular is invisible in a square footage number and can add half again to the time, because every surface has to be cleared, cleaned and put back.
| What you hear | What it usually means | Multiplier |
|---|---|---|
| We have a cleaner but she left | Maintained, light soil | 0.85 |
| Normal family house | Average lived-in | 1.0 |
| It has got away from us a bit | Months of buildup, clutter | 1.35 |
| Nobody has been in there for a while | Walk it before quoting | 1.8 or refuse |
Whichever you pick, the number to carry forward is the one you can defend to the customer when the invoice is larger than the phone estimate.
The second room is faster than the first
Setup does not repeat. Filling buckets, laying out cloths, plugging in the vacuum, mixing whatever needs mixing — that block of time happens once whether you clean one room or nine. So does the trip. The result is that the marginal cost of the third room in a house is far below the average cost of the first, and the marginal cost of a second house on the same street is far below the cost of a house across town.
Work it as a rate per hour of your day rather than a rate per hour of cleaning. A three hour clean with forty minutes of travel and twenty of setup is four hours of your day. At 45 dollars an hour billed on cleaning time only, that is 135 dollars for four hours, or under 34 an hour actually earned. Bill the overhead, raise the minimum, or fill the route — those are the three levers, and route density is the one that also makes the customer happier because you arrive when you said you would.
Turning hours into a number the customer accepts
Flat quotes and hourly rates fail in opposite directions. A flat quote on a house you have not seen transfers all the risk to you. An open hourly rate transfers all of it to the customer, and they hate it, because they cannot budget. The middle that works for most one-person operations is a flat price for recurring work once you have cleaned the place once, and an hourly rate with a written not-to-exceed for first cleans and move-outs.
Supplies are worth listing separately even when they are small. It makes the labor line legible, and it stops a customer mentally converting your whole invoice into an hourly wage. If you want to sanity-check what your rate has to be to cover an actual business rather than a wage, run it through the freelance rate calculator — the arithmetic on unbillable hours, equipment and taxes is the same trade whatever the trade is.
One thing that is not optional
Never mix cleaning chemicals. Bleach with an ammonia-containing cleaner produces a toxic gas, and bleach with an acid — many toilet bowl and lime removers are acidic — releases chlorine. Both have killed people in small bathrooms with the door shut. Use one product at a time, at the dilution on its own label, rinse between products, and ventilate. There is no cleaning problem that is solved by combining two bottles.
Questions people ask
How long does it take to clean a 2,000 square foot house?
For a standard recurring clean of an average house with two bathrooms and a kitchen, the arithmetic here gives about two hours of floor work plus about 1.3 hours of fixture work, so roughly three and a half hours of person-time. A first-time deep clean of the same house is closer to eight hours because the floor rate drops to about 425 square feet per hour and the bathroom and kitchen adders roughly double. A move-out is longer again. The single biggest thing that moves those numbers is not the house, it is how long it has been since anyone cleaned it properly.
Should I charge by the hour or by the job?
Hourly for anything you have not seen, flat for anything you have. The risk in a flat quote is entirely yours, and on a first clean you cannot see inside the oven, behind the fridge or under the beds from the doorway. Once you have cleaned a house once you know it, and a flat price is better for both sides — the customer can budget and you get paid for getting faster rather than punished for it. If you must quote a first clean flat, quote a range with the top of the range written down.
Does adding a second cleaner halve the time?
It shortens the time on site but it does not reduce the person-hours, and it slightly increases them. Two people working the same house get in each other's way at doorways and share one vacuum, and travel and setup are now paid twice. What a second person buys is a shorter window for the customer and the ability to fit more jobs in a day, not a cheaper job. Price on person-hours and treat crew size as a scheduling decision.
What should I include in supplies?
The consumables that get used up and are traceable to the job: chemicals, cloths and pads that wear out, vacuum bags and filters, bin liners. Equipment depreciation, insurance, fuel and your phone are business overhead and belong in the hourly rate rather than in a per-job supplies line, because they accrue whether or not you cleaned that day. If you list them per job you will systematically under-recover them on the days you do not work.
Can I use this for commercial or office cleaning?
The structure works but the coefficients do not transfer well. Office and commercial work is usually specified per square foot per month against a scope document, the floor rates are much higher because the areas are open and repetitive, and restroom counts drive the labor the way bathrooms do in a house. Use the fixture-adder idea and re-time your own crew on a real building to get rates you trust rather than starting from the residential numbers here.
