Calculating Employers NI in UK

[Giles]

Ladies & Gents, I'm sure this has been asked before but I need a formula for calculating an Employers NI contribution for an employee.

The variables I have to work with are:

a) Their annual salary
b) Their proportion of full time working (i.e. some staff only work, say, 20% of the time for me, but 80% for someone else, so the salary I pay them doesn't relate properly to NI bands/ceilings
c) Whether of not they are contracted in or out of SERPS
d) the National insurance bands.

I'm hoping someone will have a pre-exisiting table/formula they can point me to.

Regards

Giles Thomas

Just in case no one comes up with anyting for you, I was on the Inland Revenue website searching (I was looking for tax tables), but came across documentation for formulas for all sorts of payroll calculations.

Thanks. Quite a lot of detail there! I hope someone will come back to me with something already worked out, but otherwise your link should help with working through some of the formulas. Giles.
