This student loan Plan 4 calculator uses the threshold set in the HMRC rates and thresholds for 2026 to 2027 to show your monthly repayment, the deduction on your payslip and a year by year schedule of your balance until it is cleared or written off.

What Is a Plan 4 Student Loan?
Plan 4 applies to anyone who applied to SAAS, whether for an undergraduate or a postgraduate course. Repayments start in the April after you leave your course, and you pay 9% of income above £33,795 a year, which is £2,816.25 a month in payroll.
On a £38,000 salary you pay 9% of £4,205, which is £378.45 a year or £31.54 a month. Your employer works it out per pay period and rounds down, so your payslip shows £31. Plan 4 loans are written off 30 years after the April you were first due to repay. If your first loan was paid before 1 August 2007, it is written off at 65 or after 30 years, whichever comes first.
How Do You Use the Student Loan Plan 4 Calculator?
Step 1: Enter Your Salary
Type your gross yearly pay before tax and an expected pay rise, and the schedule grows your salary each year while the threshold stays fixed. Type your gross yearly pay before tax and an expected pay rise. The schedule grows your salary each year while the threshold stays fixed, which is a cautious assumption.
Step 2: Add Your Balance
Enter your balance from your Student Loans Company account and the interest rate. If you are paid by the hour, the hourly to annual salary calculator converts your rate into a yearly figure first, so the schedule starts from the right income.
Step 3: Set Your Dates
Enter the April you were first due to repay. Tick the box if your first loan was paid before 1 August 2007 and add your age, so the earlier age 65 write off can be applied.
Step 4: Read Your Schedule
You will see your monthly and yearly repayment, the payslip deduction and a table of salary, repayments and balance by tax year. If you are thinking about paying extra, the savings interest calculator shows what the same money could earn instead, which helps you judge whether overpaying is worth it.
How Much Will You Repay on Plan 4 in 2026/27?
| Salary | Yearly repayment | Monthly repayment |
|---|---|---|
| £30,000 | £0.00 | £0.00 |
| £35,000 | £108.45 | £9.04 |
| £40,000 | £558.45 | £46.54 |
| £50,000 | £1,458.45 | £121.54 |
On Plan 4 in 2026/27, a £30,000 salary repays nothing, £40,000 repays £558.45 a year (£46.54 a month) and £50,000 repays £1,458.45 (£121.54 a month). Because the Plan 4 threshold is higher than Plan 1, 2 or 5, Scottish graduates usually repay less each month on the same salary. The GOV.UK write off rules also cancel the loan if you die or, in some cases, cannot work because of illness or disability, so the balance never passes to your family.
