It's a common misconception. As soon as you're charging you owe it to yourself to do the sums properly.
If you don't properly account for the costs of doing business, then you are effectively subsidising someone else's lifestyle.
If you are of the mindset that you've already got the gear, and you'd be putting petrol in the car anyway, and you can do without insurance, or registering to pay tax. It's just 'pocket money'. What are you really doing? You're setting a price that 'the market' can't possibly compete with.
But that's only half the story - because your day job (and your dependants) have already paid for your business costs, someone else's family gets to save money on their luxury goods. Is that fair to you and yours? You buy a new camera which in real life is competing with a weekend away? So your family pay so that you can give someone else a bargain price on their photography.
And when you give up, because the hassle isn't worth the reward - you've lowered the market price, and the only people who can trade at the same price, have to cut the same corners:shake:.
You owe it to yourself and the industry to calculate your costs properly - If you're happy with £10 an hour, that's no-one else's business, but if you kid yourself you're earning £50 when you haven't accounted for your business properly - everyone loses.
