The MoD publish all the Freedom of Information requests they receive and often they reveal interesting things.

In response to a recent Freedom of Information Request about the costs of a Parachute Regiment soldier

The capitation rate for a member of the Parachute Regiment in Financial Year 2014/15 is £43,168. This includes Pensionable and non-Pensionable Pay, Earnings-Related National Insurance Contributions (ERNIC) and Superannuation Charges Adjusted for Past Experience (SCAPE).

Not sure how that is worked out with regards to rank and trade pay but there you go.

Also worth noting, it should be value not cost!
