UK Student Loan Calculator – Estimate Your Monthly Repayments
Find out how much you may repay towards your UK student loan based on your annual salary, repayment plan and additional income. This UK Student Loan Calculator estimates undergraduate and postgraduate loan repayments and shows your estimated annual, monthly or weekly payment.
Choose your student loan plan, enter your salary and select whether you also have a Postgraduate Loan to calculate an estimated repayment amount.
What Is a UK Student Loan Repayment?
A UK student loan repayment is an amount deducted from eligible earnings when your income exceeds the repayment threshold for your loan plan. The repayment is generally calculated as a percentage of earnings above that threshold, rather than a percentage of your entire salary.
The repayment amount depends on factors such as:
- Your student loan repayment plan.
- Your annual earnings and additional income.
- The applicable tax-year repayment threshold.
- Whether you also have a Postgraduate Loan.
How Does the UK Student Loan Calculator Work?
The calculator uses your annual income and selected repayment plan to estimate your student loan deductions.
- Select the tax year.
- Choose your undergraduate repayment plan: Plan 1, Plan 2, Plan 4 or Plan 5.
- Enter your annual gross salary.
- Enter any additional annual income included in your estimate.
- Select whether you also have a Postgraduate Loan.
- The calculator applies the relevant repayment percentage to income above the selected threshold.
- Choose annual, monthly or weekly display to view the estimated repayment.
Student Loan Repayment Formula
The calculator first combines your salary and additional annual income.
It then calculates undergraduate repayments using the selected plan's threshold.
If your income is below the selected threshold, the undergraduate repayment is zero.
If you also have a Postgraduate Loan, the calculator adds a separate repayment:
The total estimated repayment is the sum of the undergraduate and postgraduate amounts, where applicable.
UK Student Loan Repayment Thresholds
The calculator uses the following repayment thresholds in its programmed settings:
| Loan plan | 2025/26 threshold | 2026/27 threshold |
|---|---|---|
| Plan 1 | £26,065 | £26,900 |
| Plan 2 | £28,470 | £29,385 |
| Plan 4 | £32,745 | £33,795 |
| Plan 5 | £25,000 | £25,000 |
| Postgraduate Loan | £21,000 | £21,000 |
These are the thresholds hardcoded into this calculator. Always check the applicable official repayment thresholds for your tax year and loan type.
Undergraduate Student Loan Repayment Rate
The calculator applies a 9% repayment rate to income above the selected undergraduate plan threshold.
For example, if your annual income is £35,000 and your selected Plan 2 threshold is £29,385, the estimated annual repayment is calculated on the £5,615 above the threshold.
Postgraduate Loan Repayments
If you have a Postgraduate Loan, the calculator allows you to include an additional repayment alongside your undergraduate loan repayment.
The programmed calculation uses a £21,000 annual threshold and a 6% repayment rate on income above that amount.
Monthly, Weekly and Annual Student Loan Repayments
You can choose how the calculator displays your estimated repayment. It calculates an annual amount first and then converts it into an average monthly or weekly figure.
| Display option | Calculation used |
|---|---|
| Annual | Total annual repayment |
| Monthly | Annual repayment ÷ 12 |
| Weekly | Annual repayment ÷ 52 |
Monthly and weekly amounts are averages. They are not exact payroll-period deductions. Actual deductions may differ because payroll calculations use the relevant pay period and can be affected by changes in earnings.
Example of a Student Loan Calculation
Consider an example using the calculator's 2026/27 settings:
| Annual gross salary | £35,000 |
| Additional annual income | £0 |
| Selected loan plan | Plan 2 |
| Plan 2 threshold used | £29,385 |
| Income above threshold | £5,615 |
| Repayment rate | 9% |
| Estimated annual undergraduate repayment | £505.35 |
| Average monthly repayment | £42.11 |
If the Postgraduate Loan option is also selected, the calculator adds a separate repayment based on the postgraduate threshold and rate.
Salary After Student Loan Repayments
The calculator also displays an estimated salary after student loan repayments only.
This figure is not your final take-home pay. It does not deduct Income Tax, National Insurance, pension contributions or other payroll deductions.
