The formula is:
For weekly clean customers:
- First: Agency fee per hour x hours per week x 52 weeks per year.
- Secondly: Divide this by 12 months per year and you get the result.
For fortnightly clean customers:
- First: Agency fee per hour x hours per fortnight x 26 weeks per year.
- Secondly: Divide this by 12 months per year.
Some customers have pointed out that there are in fact 52.18 weeks per year and that we are giving away 0.18 weeks per year for free and they are correct :-)
