Student Loan Repayment Calculator
Tax Year 2026/27
Estimate your UK student loan repayments from your annual salary.
How Our Student Loan Calculator Works
Our student loan calculator helps you estimate how much may be deducted from your earnings for UK student loan repayments. Enter your annual salary and select the repayment plan that applies to you to see an estimated yearly, monthly and weekly repayment amount.
Student loan repayments are based mainly on your income rather than the total amount you originally borrowed. You normally make repayments only when your earnings are above the threshold for your repayment plan.
Different plans have different repayment thresholds and rules. The calculator can help with Plan 1, Plan 2, Plan 4, Plan 5 and Postgraduate Loans, allowing you to choose the option that matches your circumstances.
Repayments are usually collected automatically through payroll alongside Income Tax and National Insurance. If your earnings change because of overtime, bonuses or variable working hours, the amount deducted from an individual payslip may also change.
Please note: WeFixPay provides estimates for guidance only. Your actual repayment can differ depending on your earnings, repayment plan, payroll frequency and any additional student or postgraduate loans you have.

Student Loan Calculator FAQs
Which student loan plans does the calculator support?
The calculator can estimate repayments for Plan 1, Plan 2, Plan 4, Plan 5 and Postgraduate Loans.
Do I repay my student loan based on how much I borrowed?
Usually no. Repayments are mainly based on how much you earn above the threshold for your repayment plan, rather than the outstanding loan balance.
Are repayments deducted automatically from my salary?
If you are employed, repayments are normally collected through payroll once your earnings are above the relevant threshold.
Can I have more than one student loan deduction?
Yes. Some borrowers may repay an undergraduate loan and a Postgraduate Loan at the same time, depending on their circumstances.
Why might my actual deduction be different?
Bonuses, overtime, variable pay, payroll frequency and changes in earnings can cause the amount deducted on an individual payslip to differ from the estimate.
Student Loan Repayment Thresholds for 2026/27
Student loan repayments only begin when your earnings go above the threshold for your repayment plan. For the 2026/27 tax year, the annual 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 Postgraduate Loans.
For Plan 1, Plan 2, Plan 4 and Plan 5, repayments are normally calculated at 9% of the earnings above your plan threshold. Postgraduate Loan repayments are calculated at 6% of earnings above the postgraduate threshold.
This does not mean 9% or 6% of your whole salary is deducted. Only the part of your earnings above the relevant threshold is used when calculating the repayment.
If you receive overtime, a bonus or other additional pay, your earnings for that pay period may rise above the weekly or monthly threshold and result in a larger deduction. Your repayment can therefore vary between payslips even when your basic salary stays the same.
Some borrowers can repay a Postgraduate Loan at the same time as an undergraduate loan. In that situation, both deductions may appear on the same payslip.
Our student loan calculator gives you a quick estimate based on the plan and salary you enter. For official information and to check which repayment plan applies to you, see the UK Government’s student loan repayment guidance.
