Student Loan Repayment Calculator

Repayments are 9% of earnings above your plan's threshold (6% for Postgraduate Loans). We've selected Plan 2, the plan for most people who started university in England or Wales between 2012 and 2023.

How this calculation works

  1. 01Start with your gross income and convert it to an annual figure.
  2. 02Take off salary sacrifice and net pay pension contributions.
  3. 03Apply your Personal Allowance, tapered above £100,000 or set by your tax code.
  4. 04Calculate Income Tax band by band using rates for your region.
  5. 05Calculate employee National Insurance on earnings after salary sacrifice.
  6. 06Deduct relief at source pension contributions at 80% of the gross amount.
  7. 07Apply student and postgraduate loan repayments above each threshold.
  8. 08Subtract everything to reach estimated net pay, then split it by period.

Real payroll can differ because tax and NI are worked out per pay period, and your tax code may include adjustments HMRC hasn't told you about. See our methodology.

2026/27 thresholds

Plan 1: £26,900. Plan 2: £29,385. Plan 4 (Scotland): £33,795. Plan 5: £25,000. Postgraduate Loan: £21,000. If you have more than one undergraduate plan, repayments are based on the lowest threshold.

Repayments are based on gross pay

Pension contributions made through salary sacrifice reduce the earnings used for student loans. Relief at source contributions don't.

Understanding your student loan calculator result

The repayment is an income-linked payroll deduction, not a percentage of the outstanding balance. The plan determines the threshold, while a postgraduate loan can be collected at the same time as an undergraduate plan.

Checking two loan deductions

Scenario: Select the undergraduate plan shown in your student finance account and add Postgraduate Loan if both apply. Enter gross pay before ordinary pension deductions.

How to use the result: The result separates loan repayments from Income Tax and NI. It estimates the payroll cost, but not the date the balance will be cleared or the interest added.

Details to check before relying on the estimate

  • Confirm the plan with the Student Loans Company.
  • Bonuses and overtime can create repayments in the pay period received.
  • Salary sacrifice may reduce repayment earnings; relief-at-source pensions do not.

Putting the estimate into perspective

Use the repayment estimate as a cash-flow figure, not a debt-clearance forecast. A balance forecast also needs information about interest, future earnings and your actual loan account.

Does a student loan repayment depend on my total debt?

No. Repayments are a percentage of income above a threshold, not a fixed amount based on what you owe. Loans are written off after the period set for your plan.
