Should I Pay Off My Student Loan? - April 2026

Whether you should overpay a UK Plan 2 student loan depends less on the headline balance and more on whether you are likely to clear it in full before the write-off date. That makes this a very different decision from overpaying a mortgage, car loan, or personal loan.

Understanding Student Loan Interest

As of April 2026, Plan 2 borrowers repay 9% of income above the annual threshold of £29,385. Interest varies with income and is currently up to 6.2%. The government has also announced that the maximum rate for Plan 2 and Plan 3 loans will be capped at 6% from 1 September 2026 for the 2026/27 academic year.

For many borrowers, the key point is this: the amount deducted each month is driven by income, not by the balance. That means a large balance does not automatically mean you should rush to clear it.

The current broad structure is:

• Earnings below £29,385 per year incur interest at the RPI rate.
• For incomes at or above the upper threshold of £52,885, the rate is RPI plus 3%, subject to any government cap in force.
• Those earning between £29,385 and £52,885 face a sliding scale between those two points.

Is It Worth Paying Off My Student Loan?

For a lot of Plan 2 borrowers, overpaying does not improve their monthly cash flow and may not reduce what they pay over their lifetime by very much. That is because:

• Repayments only start once earnings exceed the threshold.
• Mandatory repayments are a percentage of income above that threshold.
• Any remaining balance is written off 30 years after you first became eligible to repay.

In practice, overpaying tends to make the most sense only if you expect to repay the balance in full anyway. If that is unlikely, extra payments may simply reduce a balance that would otherwise have been written off.

A cautious rule of thumb

If your earnings are likely to stay near the threshold for much of your career, overpayments are often poor value.

If your earnings are high and likely to remain high for many years, overpayments may save money because you are more likely to clear the loan in full before write-off.

The difficult cases are in the middle: borrowers whose future earnings could rise enough to move them from “unlikely to repay in full” into “likely to repay in full”. For that group, salary growth, career breaks, childcare, self-employment income swings, and policy changes all matter.

Questions to ask before making overpayments

1. Are you likely to clear the balance before the write-off date?
2. Do you have higher-priority debts first, such as credit cards, overdrafts, or expensive car finance?
3. Do you have an emergency fund?
4. Are you giving up employer pension matching or other higher-value uses of cash?
5. Are you assuming your salary will keep rising, and how confident are you in that assumption?

If you cannot answer the first question with reasonable confidence, the safest default is usually to pause before making voluntary overpayments.

Important limitation of our calculator

A standard loan amortisation calculator can be useful for fixed-payment loans such as many mortgages, personal loans, and car loans. It is not a full model of a UK Plan 2 student loan.

That is because Plan 2 loans are income-contingent. Thresholds can change, interest depends on earnings and policy, and the balance may be written off before it is fully repaid. Using a standard amortisation tool as if it were a student-loan forecaster can give a false sense of precision.

When overpaying is more likely to make sense

Overpaying is more likely to be reasonable if most of the following are true:

• Your earnings are already well above the threshold and likely to stay high.
• You expect to repay the loan in full rather than have part written off.
• You have already dealt with expensive debt and built a cash buffer.
• You understand that overpayments will not reduce the mandatory 9% deduction from salary while the loan remains outstanding.

When overpaying is less likely to make sense

Overpaying is less likely to be attractive if:

• Your income is only modestly above the threshold.
• You expect interruptions to earnings.
• You are unlikely to repay the balance in full before write-off.
• You have costlier debts or higher-priority uses for the money.

Key takeaway

For Plan 2 borrowers, the right question is usually not “how high is my balance?” but “am I realistically on track to clear this before write-off?” If the answer is no or uncertain, voluntary overpayments are often not the best use of cash. If the answer is yes, overpaying may be worth considering, but it still needs to be weighed against savings, pension contributions, and other debts.

Frequently Asked Questions

Do I need to repay my student loan if I earn under the repayment threshold?

No. Plan 2 repayments only begin once your income exceeds £29,385 per year (as of April 2026). Below this threshold, no deductions are made regardless of how much you owe.

When is my Plan 2 student loan written off?

Plan 2 student loans are written off 30 years after you first became eligible to repay - typically 30 years after graduating.

Will making extra payments reduce my required monthly repayment?

No. Your required monthly repayment is always calculated as 9% of your earnings above the threshold. Making overpayments reduces the outstanding balance and future interest, but does not change your mandatory monthly deduction.

Can I use a standard loan amortisation calculator to model a Plan 2 student loan?

Not reliably. Standard amortisation calculators assume fixed payments and a fixed repayment term, while Plan 2 student loans are income-contingent and subject to changing thresholds and interest rules. They can help with ordinary fixed-payment loans, but they are not a full model of Plan 2 repayments.
