For many millennial clients, student debt has become a significant feature of their long-term financial lives.
Because of this, it is a factor that financial advisers need to consider in cashflow modelling, investment strategies, and wider wealth accumulation plans.
It can be useful to think of Plan 2 student loan repayments as an additional form of taxation. Although technically a loan, the way repayments are structured means they can materially reduce a client’s disposable income for many years, particularly as their earnings increase.
The scale of the issue is growing. According to reporting by iNews, student debt increased by around 400% in the decade to 2024/25. The future of the system is also subject to debate, with the same report suggesting that various reform proposals are under consideration by the new prime minister, Andy Burnham.
If you are working with younger accumulators, understanding how Plan 2 loans work and how repayments interact with income, tax and wider financial goals is increasingly important.
Understanding the mechanics of Plan 2 loans
Plan 2 loans apply to most students in England who started undergraduate courses between 2012 and 2023.
Unlike conventional borrowing, loan repayment is linked to income rather than to the outstanding balance.
For 2026/27, Plan 2 borrowers start making repayments once their income exceeds £29,385. They repay 9% of earnings above this threshold.
When earnings reach £52,885 or more, the loan attracts the maximum interest rate of RPI plus 3%.
Repayments are collected automatically through PAYE or Self Assessment. Any remaining balance is written off after 30 years.
According to the government’s own figures, the average student loan debt for graduates in England is approximately £47,900 to £53,000 upon finishing their courses.
Once maintenance borrowing is considered, the total debt can easily exceed £70,000.
Those figures, combined with relatively high interest rates and long repayment periods, mean that many borrowers never fully clear their balances before they are written off, and that higher earners often repay considerably more over their working lives than lower earners do.
The hidden impact on wealth accumulation
Student loan repayments need to be considered alongside the other competing financial priorities many younger professionals face.
These are likely to include:
- Getting onto the property ladder
- Starting a family
- Investing for the future.
Even relatively high-earning clients can see thousands of pounds diverted from their annual cash flow through Plan 2 repayments, and could end up repaying more than the amount borrowed.
Over the course of a career, that money represents more than simply the amount being repaid on the loan. There is also a potential opportunity cost in terms of wealth accumulation and lost investment growth.
Consider two clients, both aged 30 and earning £60,000:
- Client A has no student loan.
- Client B has a Plan 2 loan and repays around £2,755 a year – approximately £229 a month – through PAYE.
If Client B instead invested that £2,755 each year into a pension or Stocks and Shares ISA and achieved a 5% annual return, the investment could grow to approximately £94,000 over 20 years, before charges, tax, and other deductions.
This is a simplified illustration and doesn’t account for the fact that repayments would typically increase as their salary rises. Nevertheless, it demonstrates the potential scale of the opportunity cost and the wealth that money might have generated if it had been available for investment.
The pros and cons of early repayment
Whether a client should make voluntary repayments towards a Plan 2 student loan is rarely a straightforward decision. The answer depends largely on their expected future earnings and how the decision fits within their wider financial plan.
For borrowers who are unlikely to repay the balance in full before the loan is written off, making additional repayments may simply reduce the amount eventually written off, with little or no financial benefit. In these cases, directing this money towards other financial priorities could be more beneficial.
Conversely, clients with high and rapidly increasing incomes may be on course to repay their loan in full regardless. For these borrowers, reducing the balance earlier could potentially reduce the total amount of interest paid over the lifetime of the loan.
The decision should therefore be considered alongside other planning priorities, including maintaining an emergency fund, mortgage borrowing, and pension contributions.
Cashflow modelling can be particularly valuable in assessing whether early repayment is likely to improve the client’s overall long-term financial position.
The same considerations apply when parents are thinking about repaying a child’s student loan. Understanding the child’s likely future earnings is important, and a parental gift towards the balance could potentially reduce the total lifetime cost of borrowing.
However, advisers also need to consider the financial impact on the parents themselves. Helping a child financially should not come at the expense of the parents’ own long-term financial security.
Before making a substantial gift or repayment, advisers should assess whether the parents have sufficient resources to meet their own retirement needs and other financial objectives.
Bringing student loans into the wider financial plan
Plan 2 student loans are becoming an increasingly important consideration for financial advisers.
Many financial planning conversations naturally focus on mortgages, pensions and investments. Yet for many, loan deductions can be substantial.
Incorporating student loans into the wider financial plan can help advisers:
- Produce more accurate cashflow forecasts
- Identify genuine surplus income
- Assess the affordability of other priorities such as pension contributions.
It can also help explain why a client may not feel as financially comfortable as their salary might suggest.
Rather than treating student debt as a stand-alone liability, advisers can show clients how repayments interact with their income, spending, investment capacity, and longer-term objectives.
