Should I overpay my Plan 2 student loan?
Plan 2 is the plan people ask about most, because it covers a large group of graduates on very different salaries. They don’t all get the same answer.
What’s specific to Plan 2
- Repayments: 9% of income above £29,385.
- Interest: between 4.1% and 6%, rising with income. See how student loan interest works.
- Write-off: 30 years after the April you first became liable to repay.
The question that decides it
For any plan, the first thing to ask is whether you’re on course to repay the loan in full before it’s written off. If you aren’t, overpaying mostly moves money to the government early that would have been cancelled anyway. If you are, the interest is a real cost, and overpaying could be worth comparing with investing. The general logic is in should I overpay my student loan?
What tends to push Plan 2 borrowers one way or the other
Points towards not overpaying
- A balance that is large relative to your salary. Repayments are set by your income, so a big balance can outlast the 30 years.
- Modest salary growth, or career breaks, which mean smaller repayments for longer.
- The write-off date being reasonably near and the balance still large. Each extra pound repaid then tends to be a pound that would have been cancelled.
Points towards looking closely at overpaying
- A small balance relative to your salary, which you’d clear well before write-off anyway.
- A high income, where Plan 2’s interest rate is at or near the top of its range and you’d repay in full.
- Not much time left before you’d clear the loan on your current path. Overpaying then brings the finish date forward and saves the interest in between.
The middle ground is the tricky part
Many Plan 2 borrowers are close to the line, where small differences in salary growth move the answer. That’s exactly the situation where a rule of thumb fails and a year-by-year model helps. The calculator runs your loan two ways, with minimum payments only and with your overpayment, and shows what each does to your total cost and to when the loan ends.
Before you overpay anything
- Check your plan type and balance on your Student Loans Company account.
- Have an emergency fund. An overpayment can’t be taken back. See how to make a student loan overpayment.
- Check whether a workplace pension match or other tax-advantaged saving would be a better use of the money. See overpay your student loan or invest?
