Fee for Naturalization

[Perfect 4]

Hi There,
I came to UK on HSMP Visa in 2008 and got my ILR in February 2013. Now I am planning to submit my application for naturalization in the first week of March 2014. I was looking at the fee leaflet given on the Home Office website but things could not get clear to me, Can any body let me know how much I will have to pay with the following family members.
1) Myself (main applicant)
2) Wife
3) Son (under 18)
4) Daughter (under 18)
and please let me know if there are other fees for anything else like registration and ceremony etc and how much would be the grand total. Many thanks

Will any of your children turn 18 in the next 6 months?

If not:
£1550 for you and your wife+
£1178 for your two children (provided neither of them turn 18 during the time your application is considered)
Total: £2728
