Question 1

How is the in-house cost calculated?

Accepted Answer

We take your hourly wage and multiply by 1.25 to cover superannuation, leave, insurance and other on-costs, then multiply by the hours per week across 52 weeks, and add a fixed $2,500 a year for equipment, consumables and supervision. That gives the fully loaded annual cost of an employed cleaner.

Question 2

How is the contract cost calculated?

Accepted Answer

We estimate the contract using indicative Adelaide rate bands of $0.035 to $0.055 per square metre per clean, multiplied by your frequency across the year, with a $60 minimum per visit. That produces a low-to-high annual range for an outsourced contract.

Question 3

Does the comparison capture everything?

Accepted Answer

The dollar figures are indicative, but the real difference is often the non-cost factors. A contract removes hiring, cover for sick days, insurance, equipment and management overhead. Even where the raw numbers are close, contracting usually removes work you would otherwise carry.
