Tax savings on pension - Rough Calculation?

Hi All,
Apologies if this has been posted before, but I couldn't find anything in the Key Posts.
I want to do a rough calculation of how much a pension would cost (Net) per month.

Some details for example:
PAYE worker, in a company with a defined contribution pension scheme
Salary: €50,000
Employee pays: 5% pension contribution
Employer pays: 7.5% pension contribution

Is there a rough guide as to how to calculate how much would this would cost (net) per month? (Tax, PRSI, Income Levy deductions?)

Thanks,

DC

I think you'll get tax relief at the higher rate 41% plus PRSI 4%.

So your personal contribution of €2500 will only cost €1375 after tax.

Great. Thanks for the info!
