I think Kewcucumber's point "I don't think what you earn is necessarily the most relevant factor in how well off you are." is a very fair one.
My very good friend lives in rural Somerset, we live in Dorset (in what is termed a village but isn't rural). My DH earns a little more than her DH, she earns a bit more than me. Our houses are very similar, both have two cars - one older one as a family car and a slightly newer one for the DH's. Their mortgage is less than ours but they pay maintenance to a DD he has from a previous relationship, so on the face of it our finances are and have always been relatively similar as have our life styles (combined income for both families a fair bit less than the OPs)
I couldn't understand why they were suddenly finding it tougher than us financially and neither could she so we sat down to work it out.
What it came down to is that because they live rurally they both do a high mileage compared to DH & I who work from home. Her petrol was £300 a month (S reg volvo) and her DH about £75 on average. Their electricity bill was about £48, then they are on oil for central heating and cooking which was coming to £200 a month (she has an Aga and had been having it on all year round as she grew up with one being a farmer's daughter, accepts it will have to go off next year). So a total of £623 a month on travel and energy.
Our expenses for the same are £75 a month for gas and electricity and gas, £60 a month on petrol. So straight away we are nearly £500 a month better off than her because we don't live in a rural place, both work from home and have mains gas.
Winegoddess, I'm sorry you've had such a reaction to your thread. I can see your point, you should be able to live comfortably on that amount but can also see why you might be finding things hard atm, however I'm sure that going over your outgoings really carefully will make a big big difference. Loads of good tips on this thread and many others if you have a look at some of the food /money threads and as said before, moneysavingexpert.com is brilliant.
