Frequently Asked Questions

How do UK student loan repayments differ from US loans?
US loans typically require fixed monthly amortizing payments regardless of employment status. In contrast, UK student loans (Plan 2 and Plan 5) function as an income-contingent payroll deduction: you only repay 9% of earnings exceeding the statutory threshold (£27,295 for Plan 2; £25,000 for Plan 5), and any remaining balance is cancelled after 30 to 40 years.
How is Australian HECS-HELP calculated?
In Australia, HECS-HELP debts carry 0% commercial interest and are indexed annually to the lower of CPI or WPI. Compulsory repayments are calculated based on your total repayment income once it reaches the minimum threshold ($54,435 for 2024–25), with statutory rates ranging from 1.0% to 10.0%.
Should I make voluntary extra repayments on student loans?
For fixed-rate commercial loans with interest rates above 5-6%, extra payments deliver guaranteed interest savings. For income-contingent government loans (such as UK Plan 2 or AU HECS), voluntary repayments may not benefit borrowers who expect their debt to be cancelled or who do not reach high lifetime earnings.
