Our Student Loan Repayment Calculator (UK) estimates how much you may repay based on your annual salary, bonus and student loan plan.
The calculator displays your estimated repayments together with your repayment threshold, taxable income above the threshold and the remaining amount to repay during the current tax year.
A Student Loan Repayment Calculator (UK) is a simple tool that estimates how much you may repay towards your student loan based on your annual salary and the repayment plan you are on. Whether you have a Plan 1, Plan 2, Plan 4, Plan 5 or Postgraduate Loan, understanding your repayments can help you budget more effectively and make informed financial decisions.
Unlike many other types of debt, UK student loan repayments are linked to your income rather than the amount you originally borrowed. This means your monthly or annual repayments increase as your earnings rise, and if your income remains below the repayment threshold, you generally won't make repayments until your earnings exceed that level.
This calculator provides an estimate only, but it can help you understand how different salaries, promotions and career changes may affect your repayments over time.
Student loan repayments in the UK are usually deducted automatically through the Pay As You Earn (PAYE) system if you are employed. If you are self-employed, repayments are generally calculated and collected through your annual Self Assessment tax return.
Unlike traditional loans, student loan repayments are based on your earnings above a specific repayment threshold rather than the total amount you borrowed.
Each repayment plan has its own threshold and repayment rules. Once your earnings exceed the relevant threshold, you normally repay a percentage of your income above that limit.
Repayments stop automatically if your earnings fall below the threshold, which means your monthly payments can change throughout your career.
Most graduates who received financial support through the UK student finance system will eventually begin repaying their student loan once their income exceeds the repayment threshold for their particular loan plan.
People who commonly make repayments include:
If your earnings remain below the threshold, you generally won't be required to make repayments during that period.
The UK currently operates several different student loan repayment plans. Which plan applies to you depends on where and when you studied.
The main repayment plans include:
Each plan has its own repayment threshold, repayment rules and interest calculations. Knowing which plan you are on is essential when estimating your repayments accurately.
Plan 1 loans generally apply to students who studied in England or Wales before September 2012, as well as some students from Northern Ireland.
Repayments begin once your income exceeds the Plan 1 repayment threshold. You only repay a percentage of the earnings above that threshold, rather than your entire salary.
Plan 1 loans often have different interest rates compared with newer repayment plans, making them one of the more established student finance arrangements in the UK.
If your salary increases over time, your repayments will usually increase as well, although they remain linked to your earnings rather than the total balance outstanding.
Plan 2 is one of the most common student loan plans in England and generally applies to students who started undergraduate courses from September 2012 onwards.
Many graduates currently repaying student loans are on Plan 2, making it one of the most frequently searched repayment plans in the UK.
Repayments begin only after your earnings exceed the applicable repayment threshold. As your income rises, your repayments increase proportionally, while lower earners continue to benefit from reduced or zero repayments.
Understanding how Plan 2 repayments work can help graduates estimate take-home pay more accurately and plan for future salary increases.
Plan 4 applies to many students who studied in Scotland and received funding through the Scottish student finance system.
Although repayments work in a similar way to other UK student loan plans, Plan 4 has its own repayment threshold and rules. Graduates only begin making repayments once their income exceeds the relevant threshold.
Because Scotland operates its own student finance arrangements, it is important to select the correct repayment plan when using a Student Loan Repayment Calculator (UK). Using the wrong plan could result in inaccurate repayment estimates.
If you studied in Scotland, choosing Plan 4 in this calculator provides a more realistic estimate of your annual and monthly repayments.
Plan 5 is the newest undergraduate student loan repayment plan introduced for many students beginning higher education in England from August 2023 onwards. Like the previous repayment plans, repayments are linked to your earnings rather than the amount you originally borrowed.
Graduates only begin making repayments once their annual income exceeds the repayment threshold for Plan 5. Repayments are automatically deducted through PAYE if you are employed, while self-employed individuals generally repay through Self Assessment.
Although the repayment process is similar to earlier plans, Plan 5 has different repayment thresholds and loan terms. Using the correct repayment plan in this calculator helps provide a more accurate estimate of your repayments.
Postgraduate Loans work differently from undergraduate student loans. If you have a Postgraduate Master's or Doctoral Loan, repayments are calculated separately from undergraduate loans and may be deducted alongside any existing Plan 1, Plan 2, Plan 4 or Plan 5 repayments.
Because postgraduate repayments are calculated independently, some graduates may repay two different student loans at the same time. Understanding how both repayments work can make budgeting much easier.
This calculator allows you to estimate repayments for Postgraduate Loans separately, giving you a clearer picture of how much you may repay each year.
Student loan repayments are calculated only on the portion of your earnings above the repayment threshold for your loan plan. If your salary is below the threshold, your repayment is usually zero.
For example, if your repayment threshold is £28,470 and you earn £35,000, repayments are calculated only on £6,530 rather than your full salary.
Some graduates choose to make voluntary repayments to reduce their outstanding student loan balance. Whether this is worthwhile depends on factors such as your repayment plan, expected future earnings and other financial priorities.
Many people prefer to build emergency savings or repay higher-interest debts before making extra student loan repayments.
Yes. Bonuses usually count as taxable earnings and may increase your student loan repayments if they push more of your income above the repayment threshold.
Although student loan deductions are normally taken from your payslip, viewing repayments over different periods can make budgeting easier. This calculator lets you compare annual, monthly and weekly repayment estimates.
Each student loan plan has its own repayment threshold. You only begin making repayments once your earnings exceed the threshold for your specific plan.
Your repayment is calculated only on the income above the threshold rather than your total salary.
For example, if your salary exceeds the threshold by £5,000, repayments are based only on that additional £5,000 rather than your full annual income.
Repayment thresholds may change over time, so checking current figures regularly helps ensure your repayment estimates remain accurate.
Interest is added to your student loan balance while you study and continues after graduation until the loan is repaid or written off according to the terms of your repayment plan.
The interest rate depends on your loan type and may vary over time. Unlike many commercial loans, the amount you repay each month is generally based on your income rather than the outstanding balance.
This means that although interest increases the amount you owe, your monthly repayments are primarily determined by your earnings above the repayment threshold.
Your annual salary is the single biggest factor affecting student loan repayments. As your earnings increase, the amount you repay also increases because repayments are calculated as a percentage of your income above the relevant threshold.
If your salary falls below the repayment threshold, repayments usually stop automatically until your income rises again.
This flexible repayment system is one of the main differences between student loans and traditional personal loans, where fixed monthly repayments are normally required regardless of income.
Using this Student Loan Repayment Calculator (UK) allows you to compare different salaries and understand how promotions, career changes or additional income may affect your repayments.
Although student loan repayments are often deducted from your monthly salary, many graduates prefer to estimate both their annual and monthly repayments when planning their finances.
Annual repayment estimates provide an overview of the total amount you may repay during a tax year, while monthly estimates help you understand how much may be deducted from each payslip.
Both figures can be useful when comparing job offers, negotiating salaries or planning household budgets.
Annual Salary: £30,000
Student Loan Plan: Plan 2
If your salary exceeds the repayment threshold, only the income above that threshold is used to calculate repayments. Your estimated annual repayment can then be divided into monthly deductions through PAYE.
Annual Salary: £45,000
Student Loan Plan: Plan 5
As earnings increase, repayments also increase because a larger portion of your salary exceeds the repayment threshold.
Annual Salary: £65,000
Student Loan Plan: Postgraduate Loan
Higher earners generally repay more each month, although repayments remain linked to income rather than the outstanding loan balance.
Using different salary figures in this calculator can help you understand how career progression may affect your repayments over time.
One of the biggest factors influencing student loan repayments is your annual salary. Because repayments are based on earnings above the repayment threshold, receiving a pay rise will usually increase the amount you repay each month.
For example, moving from a salary of £30,000 to £40,000 may increase your monthly repayments because a larger proportion of your income exceeds the repayment threshold. However, if your salary remains below the threshold for your repayment plan, your repayments generally remain at zero.
Many graduates use a Student Loan Repayment Calculator (UK) before accepting a new job or negotiating a salary increase. Comparing different salaries can help you estimate how much additional income you will actually take home after student loan deductions.
Remember that student loan repayments increase gradually with your earnings. Unlike some forms of borrowing, there is no sudden jump where your entire salary becomes subject to repayments.
Yes. Most borrowers are free to make additional voluntary repayments towards their student loan balance at any time. Whether doing so is beneficial depends on your personal financial circumstances.
Some graduates prefer to make voluntary repayments to reduce the total interest charged over the lifetime of the loan. Others choose not to repay early because student loans in the UK operate differently from traditional loans and may eventually be written off after a specified period under the terms of the applicable repayment plan.
Before making extra repayments, it is often worth considering other financial priorities such as building an emergency fund, paying off higher-interest debt or contributing to a pension.
A Student Loan Repayment Calculator provides a quick estimate of how much you may repay each year and each month based on your salary and repayment plan.
Some of the main benefits include:
Whether you are just starting your career or have been making repayments for several years, using a calculator can help you better understand your finances.
Many borrowers misunderstand how student loan repayments work. Avoiding these common mistakes can help you make better financial decisions.
Using an up-to-date calculator helps reduce these common misunderstandings and provides more realistic repayment estimates.
