I have a family asking for part time care, 10 days a month. How do you calculate how much you should be charging? They didn't say how many days a week they need care.

If I give them the daily rate I give to my current part time(2 days a week) family at the end of the month family 2 pays more. But again family 2 use 10 days of the month where current family only uses between 8 to 9 days(current family comes only Monday and Tuesday). Now, do you think it is fair on my current family if I ask the same amount?

I know it is complicated.

Thanks in advance.
