Ok, so I feel a bit dumb not been able to do this myself, however I've already spent a couple of hours trying to work this out and it will probs take one of you guys 2min (if that!)
Im basically trying to re-arrange a formula that I use to work out my profit margin on a job.
to try and keep things simple i'll show you what I normally do and then explain what I want to do.
I first work out the price of my job, which for this example I will say this is £1000.00
I will then calculate what my labour and materials come too - for this example I will call this £700.00
I then subtract the Labour/materials from the price of the job, which gives me £300.00
I then divide the £300.00 by the price of the job which was £1000.00. This gives me 0.3 and as a percentage 30%
What im wanting to achieve is to constantly have the 30% as a percentage and the formula I use work out the price of the job, which at the minute I'm having to guess at and change the amount until I arrive at the 30% mark.
So the constants that I have are the £700.00 for labour and materials and the 30% that I want to total £1000.00
Does this make sense?
Thanks in advance if you can help!
