What this calculator does

This calculator estimates annual and monthly student loan repayments for UK Plans 1, 2, and 4 by applying the standard repayment percentage to earnings above each plan threshold. It gives a clear view of how repayments may affect your monthly budget.

Who should use this calculator

Borrowers subject to UK student loan repayment rules, recent graduates, and employees wanting to understand the repayment impact alongside take-home pay should use this tool.

Which plan are you on?

It depends on where and when you started your course. Plan 1 generally covers English and Welsh students who started before September 2012, plus most Northern Irish students. Plan 2 covers English and Welsh students who started from September 2012. Plan 4 applies to Scottish students. Each has a different repayment threshold, so at the same salary your monthly repayment differs by plan. If you are unsure, check your online student loan account rather than guessing — repaying on the wrong assumption can leave you budgeting for the wrong figure.

Three things borrowers often get wrong

• It is 9% of income above the threshold, not 9% of your salary. If you earn just over the threshold, your repayment is small — not 9% of everything you earn.
• It behaves like a graduate tax, not a normal debt. Repayments stop automatically if your income falls below the threshold, and any remaining balance is written off after a set period regardless of how much you have repaid.
• It does not appear on your credit file. A UK student loan does not affect your credit score, though lenders may count the monthly repayment when assessing mortgage affordability.

How this calculator works

Select the student loan plan to use its repayment threshold, enter your earnings, and the calculator applies the standard repayment rate (commonly 9%) to income above the threshold to compute annual and monthly repayments. Interest and write-off rules are not modelled.

How to interpret your result

Displayed repayments are estimates based on thresholds and a fixed repayment percentage. Use them to budget and compare scenarios; they do not include interest accruals or account for potential write-off policies.

Example

If you earn £30,000 on a plan with a £25,000 threshold, repayments apply to £5,000 at 9%, giving annual repayments of £450 (≈£37.50/month). Adjust inputs for your exact threshold and income.

Limitations & disclaimer

This tool is an estimate only. It does not model interest, write-offs, or regional exceptions. For specific repayment schedules and official thresholds consult your loan servicer or government guidance.
