Here's my 2 cents on pricing:
The NMW is currently £8.21 for an employed person with paid holiday.
Therefore, as self employed, I believe that you could be charging at least £8.89 per hour of your time to allow yourself to still be paid for 4 weeks holiday, based on a 40 hour work week. You should calculate what it is for you. I will base my entire post on a 40 hour working week and 48 weeks per year.
Then you need to add in
every single pennythat it costs to run your business.
Your supplier should be able to help you with cost per service information.
For annual costs, such as website and insurance, divide the cost by weeks worked and then hours worked per week. So your insurance at £50 a year works out to 50 ÷ 48 ÷ 40 = 26p per hour of your time.
If you do this for every cost you incur, you will see what you need to be charging as a minimum.
It doesn't matter if you are a home salon - I am - but you need to be meeting your costs at an absolute minimum.
You then need to build in a portion of money to cover future training and continued development and growth.
You may worry that you will lose clients if you go from £10 to £20, and you may well lose some - who doesn't want great nails for basically nothing?! However, consider this example:
Tech A charges £10 per client and has running costs of £6 per client. She is super busy and has 20 clients!!
Tech B charges £20 and is not so busy - she only has 8 clients
She also has running costs of £6 per client.
Tech A brings in £200 a week. She's pretty happy with that for a part time gig. £200 isn't a bad top up afterall, right? Except it's not - she only makes £80 once she takes off her costs.
Tech B looks at Tech A with all her clients and maybe feels a bit envious - she only brought in £160 this week. However, her costs are also much lower. After subtracting everything, she's left with £112 for doing considerably less work.
You may lose the clients who don't want to pay for your work, but you will make up the difference from those who are happy to pay for quality. And they will be loyal clients - price-motivated clients will be off as soon as they see Six Pound Sally down the road. Woop! Cheap nails! And a tech who can't even afford to buy herself lunch.
Finally, your nails are lovely and worth more than £20 (a lot more, depending on the product).
