Student loan repayment calculator UK 2026/27
Estimate one plan’s annualised student-loan repayment from gross annual salary using the published 2026/27 threshold and rate.
For planning only. Payroll calculates deductions by pay period.
Estimated student-loan repayment
Annualised estimate. Employer deductions are normally calculated by pay period.
Estimate student-loan repayments from salary
Enter annual gross salary and choose one plan. The calculator applies the 2026/27 annual threshold and rate to show a simple annual, monthly-equivalent and weekly-equivalent estimate. It is a clear planning view, not a copy of payroll software.
GOV.UK says repayments use income before tax and other deductions. Plan 1, 2, 4 and 5 use 9% of income above their threshold; postgraduate loans use 6% above theirs.

Check the official repayment guidance for current monthly and weekly thresholds, interest information and multiple-plan rules.
Why your student-loan deduction can differ from this estimate
Employers calculate deductions for each pay period. A monthly bonus or overtime payment can exceed that month’s threshold even when annual income is lower, and GOV.UK explains that a refund may be possible in some circumstances. This page annualises the calculation to make salary comparisons easier.
Use the plan shown in your Student Loans Company account or payslip. Do not guess a plan only from the year you began study.
More than one student loan
This calculator deliberately supports one plan. Multiple-plan repayments can have different rules, especially where a postgraduate loan is involved. Use the official guidance and payroll records for that situation. The site’s take-home pay calculator also accepts one plan and carries the same limitation.
Student-loan repayment questions
Does the amount I owe change the repayment rate?
Not in this income-based estimate. GOV.UK explains that repayment depends on income above the relevant threshold.
Are repayments taken before tax?
The threshold test uses income before tax and other deductions. This page shows a simple annualised estimate.
Does a bonus affect repayments?
It can affect the payroll-period deduction. Use the bonus scenario calculator for a combined annualised salary-and-bonus comparison.
