I had a look at student finance. Say you borrow £9,000 a year for fees and £7,675 in maintenance loans a year (London amount). It works out at a little over £50,000 in loan. A huge shocking amount, yes.
However, it doesn't matter how much you borrow, your payments are based on your salary. You pay back 9% of your income over £21,000. If you don't pay back the full amount after 30 years it is written off.
So, you borrow £50,000
Say your earnings are £35,000 a year.
£35,000-£21,000 = £14,000 9% of £14,000 is £1260 a year, or £105 a month.
But £1260 x 30 is only £37,800. The rest is written off.
Obv, I have discounted the inflationary interest and I haven't double checjked the maths. But for anyone thinking that going next year is going to be unaffordable, it isn't really. You might not end up paying that much more back than if you went this year, I work it out as £30,909 this year, London based. Plus this year's people pay back at earnings over £15,000.
OK if you get a good job in the city then you will pay it all back. But you'll be too busy drinking expensive champers to notice.
