About this calculator
Compare per-visit professional pricing with renting or buying equipment. The break-even estimate uses annual professional cost minus chemical costs; if that annual saving is zero or negative, the purchase price never breaks even.
Worked example
calculated with the default values below
Carpet area 1,200 sq ft · Rooms 4 · Professional price per square foot 0.35 $ · Professional minimum per room 45 $ · Rental cost per day 40 $ · Chemicals per clean 15 $ · Cleanings per year 2 · Price of buying a machine 300 $ Professional clean 420.00 $ · Rental and chemicals 55.00 $ · Rental per year 110.00 $ · Saving from doing it yourself 730.00 $ · Years to pay off a bought machine 0.4 years · Cheapest option Renting a machine

Formula and variables
B = C_m ÷ (n × (P − c)), P = max(A·p, r·m)
- B
- Break-even in years
- C_m
- Cost of buying a machine
- n
- Cleanings per year
- P
- Professional cost per visit
- c
- Chemical cost per cleaning
- A
- Carpet area (sq ft)
- p
- Professional price per sq ft
- r
- Rooms cleaned
- m
- Minimum charge per room
Break-even years = machine price ÷ [(professional price per visit − chemical cost per visit) × cleanings per year]. If annual savings are zero or negative, there is no finite break-even. Maintenance and resale value are excluded.
Frequently asked questions
When does buying a carpet cleaner break even?
The tool divides the machine price by annual savings from replacing professional visits, after subtracting chemical costs. With the defaults, annual savings are ($420 − $15) × 2 = $810, so a $300 machine reaches the modelled break-even in about 0.37 years. Rental cost is not included in the ownership path. If annual savings are zero or negative, no finite break-even is shown; maintenance and resale value are not modeled.
