Everything about Student Loan Repayment Calculator
📋Overview+
Computes 2025/26 student loan repayments: 9% of income above your plan's threshold (Plan 1 £26,065 · Plan 2 £28,470 · Plan 4 £32,745 · Plan 5 £25,000) plus 6% above £21,000 for a Postgraduate Loan — both collected together through PAYE or Self Assessment.
💡 Best practices
- Repayments stop automatically when income falls below the threshold — they follow income, not the loan balance.
- Interest rates and write-off horizons differ by plan; overpaying may or may not make sense depending on expected earnings.
- Thresholds change most Aprils — re-check them each tax year.
🔢 Concrete example
£40,000 income on Plan 2 with a Postgraduate Loan: 9% of £11,530 (£1,037.70) plus 6% of £19,000 (£1,140) — £2,177.70 a year, about £181.48 a month.
