UK Student Loan Repayment Calculator 2026/27

Enter your salary and loan balance to calculate your monthly repayment, total cost, and years to repay. Updated for 2026/27 thresholds and interest rates across all plan types.

How student loan repayment works

Student loan repayments are taken automatically from your salary by your employer. You repay 9% (or 6% for Postgraduate loans) of everything you earn above your plan's threshold. If your salary drops below the threshold, repayments stop automatically.

Which plan am I on?

Your plan depends on when and where you studied. Plan 1 covers loans taken out before September 2012 in England/Wales or any time in Northern Ireland. Plan 2 covers loans from September 2012 onwards in England/Wales. Plan 4 is for Scottish students. Plan 5 applies to courses starting from August 2023 in England. Check your payslip or the Student Loans Company website.

Should I repay my student loan early?

This depends on whether you will fully repay your loan before it is written off. If your balance will be written off (meaning you pay back less than you borrowed), early repayment costs you money. If you will fully repay, early repayment saves you interest. Use the calculator to check your specific situation.

Plan 2 interest rates explained

Plan 2 interest varies with income and is capped at 7.1% for the period beginning September 2026. The repayment threshold is separate from the interest-rate thresholds, and rates can change during a tax year. The calculator defaults to the maximum rate, so adjust it if your actual Student Loans Company statement shows a lower rate.
