UK university student finance - should I use my sponsorship money to pay the debt?
Let me run some simplistic numbers, ignoring inflation. You have the opportunity to borrow up to 51K. What matters (and varies) is your postgraduation salary. Case 1 - you make 22K after graduation. You pay back 90 a year for 30 years, paying off at most 2700 of the loan. In this case, whether you borrow 2,800 or 28,000 makes no difference to the paying-off. You would do best to borrow as much as you possibly can, treating it as a grant. Case 2 - you make 100K after graduation. You pay back over 7K a year. If you borrowed the full 51, after 7 or 8 years it would be paid off (yeah, yeah, inflation, interest, but maybe that might make it 9 years.) In this case, the more you borrow the more you have to pay back, but you can easily pay it back, so you don't care. Invest your sponsorships and savings into something long term since you know you won't be needing to draw on them. Case 3 - you make 30K after graduation. Here, the payments you have to make actually impact how much disposable income you have. You pay back 810 a year, and over 30 years that's about 25K of principal. It will be less if you account for some (even most) of the payment going to interest, not principal. Anything you borrow above 25K (or the lower, more accurate amount) is "free". If you borrow substantially less than that (by using your sponsorship, savings, and summer job) you may be able to stop paying sooner than 30 years. But even if you borrow only 12K (or half the more accurate number), it will still be 15 years of payments. Running slightly more realistic versions of these calculations where your salary goes up, and you take interest into account, I think you will discover, for each possible salary path, a number that represents how much of your loan is really loan: everything above that is actually a grant you do not pay back. The less you are likely to make, the more of it is really grant. On top of that, it seems to me that no matter the loan/grant ratio,  "borrow as much as you can from this rather bizarre source" appears to be the correct answer. In the cases where it's all loan, you have a lot of income and don't care much about this loan payment. Borrowing the whole 51K lets you invest all the money you get while you're a student, and you can use the returns on those investments to make the loan payments.
