Students are facing debts rising to more than £50,000 when they leave university.
The poorest will owe around £57,000 when they graduate, according to the Institute for Fiscal Studies (IFS).
Interest rates on student loans will be 6.1% from September 2017, and tuition fees are also rising to £9,250.
It means that, on average, students will graduate having already built up £5,800 in interest.
Ben Jones, 22, finished his course this summer with more than £40,000 of debt. His sister Florence, 25, graduated in 2015 with around £15,000 less to pay back.
