Starting out needs some serious planning. You need to work out your fixed costs, that is everything you need to pay for whilst being self employed, and i mean everything. Mine works like this. The wife works, and her wage pays all the monthly standing orders for the household running costs, it also pays the costs for her to live, like mobile phone, car fuel, tax, insurance etc, then there is a bit leftover, this is her spending money for things like nights out, shoes and handbags. What she doesnt spend goes into our joint saving account. My side of the deal is that i have to bring in enough for us to live on for food, holidays and life's luxury's. My fixed cost's are Part P fees, van running costs, tools and equipment replacement, various insurances, accountant, work wear, and so on, your's maybe different. Once i have worked out my fixed costs i then add on how much i need to earn for us to live, and how many hours i want to spend earning it including time spent at home working on the business, add this lot together and that is my break even point. Then i decide how much profit i want to make. Add the whole lot up and this will give you your annual cost of trading as self employed.
Take the annual figure, divide it by how many weeks you want to work, this will give you a weekly wage, divide it again by how many hours you want to work per week, and you now have your'e hourly rate. Only you can decide if this figure is competitive enough for you to go it alone. Its no good just sitting down and saying, OK i am going to go self employed next week, and i will charge £ X per hour. You need to know exactly where you stand, if you just go in on a whim you may find that you need £50 per hour, if you trade at £25 then your venture will end in tears. If you need to get finance from a bank you will need a business plan, and this is the first bit of information they will want to see. If you cant show where you're profit is coming from, then they cant see how you will repay them, and you know what the answer will be.
Dont forget to factor in any tax liabilities, after the first £5000 or so you will be liable for income tax and NI, set aside 28% of your income to cover it, 20% income tax, and 8% NI. If you turn over more than about £1300 per week you will also need to be VAT registered.
Enjoy
