Methodology
How the calculator turns a local overseas salary into an estimated UK student loan repayment.
Formula
The calculator converts your gross annual local salary into GBP, subtracts the relevant overseas earnings threshold, then applies the repayment rate.
monthly repayment = max(0, salary in GBP - overseas threshold) × repayment rate ÷ 12
Repayment rates
- Plan 1, Plan 2, Plan 4, and Plan 5: 9% above the overseas threshold.
- Postgraduate Loan: 6% above the overseas threshold.
- If you have both an undergraduate loan and a Postgraduate Loan, the estimates are calculated separately and added together.
Data sources
Thresholds and exchange rates are loaded from GOV.UK overseas earnings threshold publications for each supported tax year. The app stores fetched threshold data locally so older published tables remain available if GOV.UK moves or replaces pages.
Limitations
This is an estimate, not an official Student Loans Company notice. Your actual payment may differ if SLC uses a different exchange rate, updates thresholds, assesses income differently, or applies account-specific rules.
