About Student Loan Repayment Calculator
This student loan repayment calculator shows how much is taken from your pay each month and each year for Plan 1, Plan 2, Plan 4 and Plan 5 undergraduate loans, and for a postgraduate loan. It uses the thresholds for the 2026/27 tax year, which runs from 6 April 2026 to 5 April 2027, and it shows the threshold and the rate used for each loan so you can check the working against GOV.UK.
Enter your income before tax as a yearly, monthly or weekly figure, choose your plan and tick the box if you also have a postgraduate loan. You see the repayment per month and per year, with a breakdown for each loan. If you have both an undergraduate and a postgraduate loan, the two repayments are added together, which is why people with both loans repay 9% and 6% of their income above the thresholds.

Frequently asked questions
What is the student loan repayment threshold for 2026/27?
For 2026/27 the yearly thresholds are £26,900 for Plan 1, £29,385 for Plan 2, £33,795 for Plan 4, £25,000 for Plan 5 and £21,000 for a postgraduate loan. Repayments are 9% of income above the undergraduate thresholds and 6% above the postgraduate threshold. The monthly threshold used for each loan is shown in the breakdown.
Is student loan repayment worked out on gross or net pay?
It is worked out on your gross income, which is the pay before income tax and National Insurance are taken off. Your employer takes the repayment from your pay through payroll, so it appears on your payslip as a separate deduction.
Does a postgraduate loan repayment add to an undergraduate one?
Yes. If you have a postgraduate loan and an undergraduate plan, you repay 9% of the income above your undergraduate threshold and 6% of the income above the postgraduate threshold. Both amounts come out of your pay, so the two add together.
Why is the monthly repayment shown in whole pounds?
GOV.UK works in whole pounds. The monthly income is rounded down, the threshold is taken away, and each repayment is rounded down. So a repayment of £45.81 is shown as £45. The yearly figure is twelve times the monthly repayment. Pay periods in payroll can still make a small difference.
