Hey Guys,

Just wondering how you guys are costing and marking up your jobs.

What I am currently doing is a 20% markup on materials and 20% on labour, and then with regards to Overheads I have a formula as follows:

Eg:
If I require £900/month to keep my business afloat and there is on average 21 working days in a month, I divide 900 by 21 to give me a daily O/H cost of £42.85.

I then work out how long the job is expected to take and multiply it by my hourly rate/daily rate.

So I end up with...

Materials incl Vat +20%MU
+ (Labour + 20%MU)
+ O/H

These added together give me my sell value.

It seems to work for me just wondering what you guys are doing?

Cheers
Mark
 
Double whatever you pay yourself and 10% on the top, for example if you pay yourself 15 quid an hour then charge 31.50, regarding mark up, it depends on the cost of materials, if you supply 2ks worth of materials you may struggle to win work with 20% of that amount on the top, but smaller amounts 20% sounds good to me.
 
Agree on the the 20% markup on larger jobs. I tend to do the markup on a per job basis. I used 20% in a general sense. Thanks for your input though.
 
£900 of overheads per month - that sounds a lot.

Mine are around £550
mine are less that. £250/month for van (inc.fuel). £20 PL insurance. £20 moby. £50 other expenses. totall. £340.
 
Whilst i think it is good having these sort of base line prices you will charge there are times where say if you are left with an empty day with no job lined up it can sometimes pay to do a job for slightly less on the labour costs too pay yourself something plus cover the days over heads and materials. it could lead to future work or referrals...
if you turn the job down as its lower than what you would normally charge then its lost turn over and a happy customer lost. Im not talking big jobs here quick little ones like cooker connections, change a light pendant to a 3 bulb job....
 
Don't forget holiday pay and sick pay, you need to factor that in as well as some money to buy a new van one day, plus tyres MOTs etc, it is suprising what you need to allow for hence 110% on your rate.
 
So when working on domestic you work over 10 hours per day?
I tend to use the £22.50 for the smaller jobs, but if its a larger job like a re-wire where I'll be there for say 8/9 days then I price it on a day rate. In hind sight I may have been wrong in doing this.

So if you manage 5 x small jobs in 1 day (allowing for travelling and getting parts between jobs, you will gross £112.50 - that's no way enough given you then need to deduct about £31 overheads - which makes your 8 hour day, out and about worth a paltry £10.18 per hour
 
Those ARE overheads.

Everything that isn't resold to a client is an overhead ....

yeah I know, what I'm saying is I have a separate line in my costing for overheads, I don't include the overheads in my labour rate.

I do my labour rate and then add on my overheads etc.

Does that make sense.

Here's a typical eg of my costing sheet.

Cost of Materials Incl Vat 249.26
+ MU @ 20%. 49.85
= Material Sell 299.12

Labour Rate @ £22.50/hr
16 Hrs 360.00
+ MU @ 20% 70.00
= Labour Sell 432.00

Overheads
Fuel @ 0.69 p/mi
19 Miles 26.22. (Based on 2 days travel return trip)
Other (Insurance etc) 85.71
Total Overheads 111.93

Job Sell 814.05

0% Contingency -

Customer Pays 814.05
 
I know my overheads, I aim for 220 days per year ....... My "hourly" rate includes my overheads, so all I have to think about is the number of hours a job will take!

surely simplifying things would make it easier, and quicker to do quotes ?

Yeah I agree, it does seem to simplify things , and this exactly the advice I was after. This is why I asked how everyone else costs their jobs. Cheers
 
£40 a call-out... small jobs @ £30/hour after 1st 30mins. larger jobs, if above 1 day then £25/hour. anything i can't write on a beermat, then a written estimate/quote.
 
I think I am just very "Bullet pointed"

I like to see on paper, what I have earned, what my O/H costs are, what my materials cost are etc.

If I was to add my O/H into my labour costs I wouldn't really know what to pay myself and I think that may come with time.....

I use Quick Books, so at the end of every month I can see to the penny how much profit I've made, and precisely what my overheads were .....

BUT as we all know overheads vary per month so budgeting and having spare cash in your business account is very important.
 
say you want wages of £15/hour..... work out the cost of tour overheads per week ( e.g. £200), then divide by 40. thats 200/40 = 5. so you charge 15+5 =20/hour.
 
I use KashFlow, which is nice for quoting, invoicing etc. Looked at Xero but not really looked at Quick Books. I've only been Self Employed since May last year, before that I was always on the cards, so this is a good learning curve for me, and your advice and knowledge is much appreciated. At the moment my O/H vary from £400 to £900pm because I've had van signage, clothing etc. I think once that all settles down I'll have a better understanding of my monthly O/H's.
 
Even for domestic?
Typical pricing for me in domestic work in Bath is £40 first hour £30 subsequent hours for small straight forward jobs.
Charge higher for out of hours call outs and weekends. If the job is larger then I will give a day rate for the job, the rate varying depending on nature of job. if its chasing, drilling and physical work then a bit more. If its just changing a couple dozen accessories in a house then a lower day rate.
 
I charge electricians out at £35 per hour or £350 per day.

I look to make a 100% mark up on my guys.

10% only on materials which is pretty standard in the non-domestic setting.

An ideal for me is a 20% profit on a job once everything is paid.

Your first year will always have high costs due to the things you have identified.

For the last 6 years my annual overheads have been around £6 k per year. I have been SE for 8 years, the first 2 years were higher...

You need to do a business plan which identifies what your monthly costs are such a fuel, the the annual costs such as insurances, mot, servicing, scheme fees, calibration etc and know when they fall....

This way you will know what your fixed annual costs are and what your variable annual costs are ....

I plan to buy new tools in months when high fixed costs fall ...

Thanks for this I have now changed from Kashflow to QuickBooks, its a lot better.
