Post Graduate Loan - Interest

As far as I know its on a par with other student loans so RPI +3% and you wont start paying till £21k. How much depends on how quickly you want to pay it back..

I get that but for example, if I was given the full £10k how much would I actually pay back with interest? Or is the interest already added into the monthly repayments?

The interest is added to the amount outstanding.
How fast you pay it off depends on what you salary is because the more you earn, the more you will pay off. This is due to it being 9% of the amount above £21,000 and we dont know how much above the threshold you would be.

Am I creating a circular argument here?

You cna mess avout with this, but its flawed since you have to make a big presumption on your earnings.

Alternative you could enter your details in a basic loan calculator based on a known number of payments over a known period and see what the repayment amounts would be for an idea.

No No! It was just me having a seriously stressed out blonde moment

However, that calculate you posted was a god send and actually gave me enough information I need! It was a rough estimate but it will do!

I must be mental having done a BA and now an MA with this student debt on my shoulders...

All i know is, that the normal 27k for 3yrs undergraduates, you end up paying back over 100k :/
