hi there,
are you lost in the time that a task is going to take? or in the price that should charge for that task ?
the latter being easier to answer.
time X hourly rate of pay + employer NI + holiday pay + % materials + % management cost + % profit = rate to charge.
hourly rate = can be anything from £6.50 upwards depending on task and local prevailing rates.
employer NI , set this at 11%
holiday pay 28 days minimum for a full time, or pro rata
% materials say 3%- 5% plus any special kit that you may hire ie access eqpt
% management cost + % profit, these are the factors that you need to determine, however if you can deliver a combined 30% to the gross profit account, then your other overheads will ideally be in at a maximum of 70 to 80 % of that 30% of that contribution.
if you can get more then great, but as jobs increase the %nett profit points will reduce.
regards
martin
