Student Loan Calculator UK

A student loan calculator estimates your monthly and annual student loan repayments based on your salary and repayment plan. UK student loans are repaid automatically through PAYE once your income exceeds your plan's threshold, at a fixed percentage of income above that threshold.

Student loan repayments are calculated as a percentage (usually 9%, or 6% for Postgraduate Loans) of your income above your plan's repayment threshold. For example, on Plan 2 with a £29,385 threshold, you repay 9% of everything you earn above that amount, not your full salary.

There are five main plans: Plan 1 (pre-2012 English/Welsh students, threshold £24,990), Plan 2 (2012-2023 English/Welsh students, threshold £29,385), Plan 4 (Scottish students, threshold £31,395), Plan 5 (post-2023 English students, threshold £25,000), and Postgraduate Loans (threshold £21,000, repaid at 6%).

Write-off periods vary by plan: Plan 1 writes off after 25 years, Plan 2 after 30 years from the April you first became eligible to repay, Plan 4 after 30 years, Plan 5 after 40 years, and Postgraduate Loans after 30 years. Any remaining balance is cancelled regardless of how much you've repaid.

Yes, if you have an Undergraduate loan (Plan 1, 2, 4 or 5) and a Postgraduate Loan, both are repaid simultaneously through separate deductions — 9% above the undergraduate threshold plus 6% above the postgraduate threshold.

This depends on your plan and likely future earnings. For Plan 2 and Plan 5 borrowers who are unlikely to fully repay before write-off, voluntary overpayments rarely make financial sense. For Plan 1 or Plan 4 borrowers close to repaying in full, overpaying can sometimes save interest.
