When to use this calculator

  • Before accepting a pay change, bonus, pension contribution, or salary-sacrifice option.
  • When you want to compare employed, self-employed, or dividend-based income scenarios.
  • When you need a simple take-home estimate before running payroll or filing returns.
  • When you are approaching the £100,000 income level and want to understand the personal allowance taper effect.
  • When you are planning a salary sacrifice arrangement and need to see the net pay impact before agreeing terms.

Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.

Goal

Estimate monthly repayment impact

Student loan deductions often feel small until they are combined with tax and pension. Seeing them together is what makes the cash-flow impact clear.

Method & assumptionsAuthoritative sources

This calculator estimates monthly and annual student loan repayments based on your gross annual income and the repayment plan you are enrolled on. Each plan has a distinct income threshold and repayment rate set by the Student Loans Company and the relevant government body, and this calculator applies the published figures for the current tax year.

Repayments are calculated on income above the threshold only — not total earnings. The calculator does not model interest accrual, loan write-off projections, or the long-term total cost of different repayment strategies. It also excludes postgraduate loan repayments, which run concurrently and have a separate threshold and rate. If you hold both a postgraduate and undergraduate loan, both deductions may appear on your payslip simultaneously. Always verify your plan type with the Student Loans Company before relying on these figures.

Common mistakes

  • !Entering gross income when you really want take-home pay, or vice versa.
  • !Ignoring pension contributions, deductions, or local tax rules that change the result.
  • !Comparing monthly and annual figures without standardising them first.
  • !Overlooking the National Insurance threshold changes that apply mid-year when rates or bands are adjusted in a Budget.
  • !Assuming a salary sacrifice benefit reduces take-home pay by the full gross amount, rather than only the after-tax cost.

What to do next

  • Check the same scenario with related pay or deduction calculators to see the full picture.
  • Keep a copy of the assumptions you used so you can compare next tax year or pay period accurately.
  • Read the related guides below if you are choosing between multiple income or deduction options.
  • If you are self-employed, run the self-employment tax calculator alongside this result to compare the net position against employed income.
  • Check whether increasing your pension contribution by even one or two percent changes the take-home significantly — use the pension calculator next.

Frequently asked

Plan 1 covers loans from English/Welsh students who started before September 2012, or Scottish/Northern Irish students. Plan 2 covers English/Welsh students who started between September 2012 and July 2023. Plan 4 is for Scottish students who started after 1998. Plan 5 covers new English students starting from September 2023 onwards — it uses the same threshold as Plan 2 (£27,295 for 2025/26) but has a 40-year write-off period instead of 30 years.
