just a guess, but based on my predictions, 25k would expect about 14% expenses.
Based on making 13k. 20% expenses.
Everyone's predictions will be way different here, but the reason for the rise if you do less, is because most of the expenses that I encure is fixed, like insurance for instance, licencing, road tax, accountants fee's etc.
My biggest expense of course is petrol for the car, which will rise with the number of customers, so will always be around the same percent against sales.
I should note that I am trad, so WFP users percent will be slightly higher, but have more sales, also live in scotland.
hope that helps

p.s. if anyone is cheaper, would love to here some advice on lowering costs.
I would also say I am 23 and am going to have higher business insurance for the car than someone that have been driving for a while so mine might be sightly higher due to that.
