Earning 25K what take home

I am in the running for a job of 25K which is down at least 15K what I used to,and is only 3 month contract.My wife works part time earns around 10k,
Just trying to figure out how much I would come out with each week,I will have to go through toll bridge 10 times a week and at least 30E in petrol. I get 340E a week as have children but I trying to find out will I be out of pocket at end of week as things so tight now that even down 20E a week would be trouble, or might keep trying to get the job I am hoping for. this job will not lead anywhere to achieve better salary,

Put your figures into http://www.deloitte.ie/tc/

and you will get a good idea. You can take some of the married persons credit so you need to put in your wife's salary aswell.
