Our Data
All thresholds, interest rates, and plan parameters are sourced from official government publications:
Our calculators currently reflect the 2026/27 tax year parameters and are updated each year. Content is reviewed annually each April when new thresholds and interest rates are announced.
Interest Calculation Method
Our calculators use annual compounding for simplicity and transparency. The Student Loans Company (SLC) applies interest on a daily basis in practice. For most users over multi-year projections, the difference is negligible (typically less than 1% of the total). However, for large balances at the maximum Plan 2 interest rate, our projections may very slightly understate total interest accrued compared to the SLC’s own system.
Plan 2 Upper Interest Threshold
The Plan 2 sliding interest rate scale transitions from RPI (3.2%) at the lower threshold (£29,385) to RPI + 3% (6.2%) at the upper threshold. For 2026/27 the confirmed upper threshold is £52,885, as announced by GOV.UK in November 2025. Our calculator uses this confirmed figure.
