Calculating your student loan repayment manually can be a headache. Using an online student loan calculator simplifies financial calculations, helps you compare your loan options, and prevents over-borrowing. Filling in key details gives you an instant idea of your current financial condition, such as how much student loan do I owe, the loan term, and the monthly repayments. With a student loan calculator, you get a clear breakdown of all the factors involved, helping you budget effectively, resulting in a stress-free educational loan journey.

What Can I Use a Student Loan Repayment Calculator For?

A student loan calculator helps students understand their options, the student loan balance, the monthly instalments, and the overall cost of the loan.

If you have a UK student loan, you can use the online student loan calculator to understand

How much will you pay each month (EMI)?
How much loan debt could you graduate with?
Student loan interest rates.
How long could it take for student loan repayment?
How much student loan do I owe?
You can compare different loan options.
You can understand your repayment schedule.

April 2026 updates on student loans include a 6% interest rate cap on student loan plan 2 loans and Plan 3 Postgraduate loans from September.

How the Student Loan Repayment Calculator Works?

Fill out the details. Enter your total student debt, course start year, course duration and the student loan plan. Then enter your current pre-tax salary to get the result.

If you are on plan 1,2,4,5, your student loan repayments equal 9% of your income over the threshold.
If you are on a post-graduate loan plan, your student loan repayment threshold is 6%.

For Example

If you have an income of £36000 per year and you are on plan 1, this means you have £3000 each month.
Deduct your plan 1 threshold from your monthly income (£3000- £2241 = £759).
9% of £759 = £68.31
So you will be paying £68.31 each month for student loan repayment.

You can not choose your student loan repayment plan. You could be on different plans if you have multiple loans.

How Much Interest Rate Do I Have to Pay on Various Plans?

Your interest rate depends on the type of plan you are on. If you are self-employed, how much loan you will repay depends on your combined income for the whole year. Working with a reputable lender, such as Mayfair Commercial Mortgages, you get tailored advice to manage your finances accurately.

Plan	Interest Rate
1 (for students who started university before Sept 2012, in England/Wales).	3.2%
4 (for students from Scotland).	3.2%
5 (for students starting from 2023 onwards).	3.2%
3 ( Post-graduate loan for Master’s or PhD).	6.2%

How Much Will I be Charged on Student Loan Plan 2 (Variable Interest Rate)?

Student loan plan 2 is for students who started university between Sept 2012 and 2023 in England.

For student loan plan 2, you will be charged a set interest rate of retail price index (RPI) +3%, which is currently 6.2%, during your study period.

This rate will change

Once you finish or leave the course (6th April).
4 years after the course started, if you are studying part-time (6th April).

After you finish or leave the course, you will be charged a variable interest rate, depending on your income.

For Example:

For an annual income of £29,000 or less, you will pay 3%
For annual income within the range of £30,000 – £53,000, approximately, you will pay 3.2% +up to 3%
For income more than £53,000, you will pay 6.2%
If you do not have a postgraduate loan and are on more than one loan type, you will pay more than 9% of your income, over the lowest threshold of all the plan types you have.
If you are on more than one plan type, and also have a postgraduate loan, you will repay 6% of your income over the postgraduate loan threshold and 9% of your income over the lowest threshold for any other plan types that you have.

Currently, the maximum interest you can accrue on plan 2 is 6.2%, which will be capped at 6%

in England in the 2026-2027 academic year.

What is a Student Loan?

In the UK, student loans are provided by the government to pay for students’ tuition and living expenses at university. You will only repay 9% of your earnings if you earn more than £26,900 per year.

Loans are paid back with interest once you graduate. Student loans come from the government and give you more protection than other loans. They are easy to qualify for, offer flexible repayment plans, and are automatically cancelled after 25-50 years.

Student loan balance amounts vary across the UK

England and Wales: £9535 per year.

Scotland: £9535 for the UK students and free for the majority of the Scottish students.

Northern Ireland: £4855 for Northern Irish students or £9535 for UK students.

How Does It Work?

Graduates are expected to start repaying, typically 9% of the income above the threshold each month, once they are out of university and their income crosses a certain threshold. Repayments are automatically deducted from salary each month, using the tax system.

Unlike a large bridging loan, student loan repayment in the UK depends on how much you earn, not how much you borrowed, and the remaining amount is eventually written off after a set period of time.

How Long Does it Take to Repay Student Loans?

Your student loan repayment plan depends on when you started your course and the course type you are enrolled on. There is no penalty if you make extra repayments to pay some or all of the loan earlier.

Plan 1 gets written off after 25 years from the April 1st your student loan started, or when you turn 65.
Plan 2 gets written off after 30 years of your graduation, or you become eligible to pay back.
Plan 4 also gets written off 30 years after you become eligible to repay.
Plan 5 gets written off after 50 years from the starting date.
Postgraduate loans get written off 30 years after the repayment begins.

How does my student loan get repaid?

Who pays back a student loan?

A principal debtor (a student, parent, sponsor or guardian) enters into a financial credit agreement with the bank. This person is responsible for the repayment of the student loan, as per their contractual agreement.
