Repayments for every UK plan in 2026/27, plus a projection to the write off date.
| Plan at your salary | Threshold | Monthly |

Thresholds and rates for 6 April 2026 to 5 April 2027. The projection is a simple yearly model that keeps thresholds and the interest rate fixed, so treat it as an estimate. Plan 1 loans taken out before 1 September 2006 are written off at age 65 instead.
Your student loan is not like a normal debt, because what you pay depends on what you earn, not on what you owe. This student loan repayment calculator covers Plan 1, Plan 2, Plan 4, Plan 5 and Postgraduate Loans, uses the thresholds published in the HMRC rates and thresholds for 2026 to 2027 and shows your monthly and yearly repayments, how long until the loan is written off and whether you are likely to clear it first.
Quick answer: A student loan repayment calculator uses (income minus threshold) × rate, with 9% for undergraduate plans and 6% for a Postgraduate Loan. On Plan 2 with a £35,000 salary, you pay 9% of £5,615, which is £505.35 a year or £42.11 a month, and your balance only affects how long you pay.

What Is a Student Loan Repayment?
Once you have left your course, you start repaying from the April after, but only when your income is above the threshold for your plan. Employees repay through PAYE, so the money comes straight out of your pay, while self employed people repay through their Self Assessment tax return.
The formula is repayment = (income minus threshold) × rate. The rate is 9% for undergraduate plans and 6% for a Postgraduate Loan. On Plan 2 with a £35,000 salary, you pay 9% of £5,615, which is £505.35 a year or £42.11 a month. Your balance only affects how long you pay for, not how much you pay each month.
How Do You Use the Student Loan Repayment Calculator?
Step 1: Choose Your Plan
You pick Plan 1, 2, 4, 5 or Postgraduate, and the interest rate updates to the usual figure for that plan. Pick Plan 1, 2, 4, 5 or Postgraduate. Your plan depends on where you lived and when your course started, and it is shown in your online student loan account. The interest rate updates to the usual figure for that plan.
Step 2: Enter Your Salary
Type your gross annual pay before tax and an expected yearly pay rise. If you work part time, the pro rata salary calculator gives you the real annual figure to enter here, which keeps the repayment accurate.
Step 3: Add Your Balance and Start Year
Enter your current balance, the interest rate and the April you were first due to repay. The write off date is counted from that April, so this field decides how many years of repayments remain.
Step 4: Read Your Results
You will see your monthly, yearly and weekly repayment, the years left until write off, and a projected total repaid. If you are paid hourly, the hourly to annual salary calculator converts your rate into a yearly salary first, so the projection uses the right income. The table also compares every plan at your salary.
