Nanny share - percentage pay increase?

[fledermaus]

Typically, by how much would you increase your nanny's pay for days/hours when it becomes a share (one extra child)?

50%, hard to know. It could be double the number of children if you had one child. There is also the hassle factor, two sets of parents to please, juggling holiday, going to someone else's home (if care is not at usual place).

No it's not 50%. In my case (4th nannyshare) it's always been 20% more.

So if paid 10 gross an hour, a share is 12 gross? As a nanny I would not do it for that, too much hassle. I would want 14 gross, so 40%. Suppose it depends on what the parents can afford, what the nanny will accept, how much additional work it is considered to be as well as the hassle involved.

Does the nanny already know the child? Is the child used to being left with people? Are both families involved willing to always take the same holiday dates? Will additional equipment need to be constantly carried back and forth between homes? Will the additional child fit in with what the others currently do, or will it restrict things? Lots of factors to look at, the easier it is the lower the cost that might be accepted by the nanny.

Yes sorry I should have clarified, 20% more net.

IME around 30% gross is normal, but it also depends how the tax is being split between employers.
