Estimate postgraduate loan repayments and the combined impact with salary tax, NI, pension, and student loan settings.
Postgraduate loans can run alongside another student loan plan, so this is a useful standalone explanation. PayBreakdown includes a postgraduate loan toggle in the salary calculator.
A postgraduate loan is repaid on top of any undergraduate plan, not instead of it. Turn both on to see the combined deduction.
Of £35,000.00 gross a year: Income Tax £4,486.00, National Insurance £1,794.40, Student loan £840.00, Take-home £27,879.60.
Student loan repayments take £840.00 a year, which is £70.00 a month. Repayments are a percentage of what you earn above the plan's threshold, not of your whole salary.
Saving £115 a month — about 5% of this take-home — becomes £7,610.59 in five years at an example 4%: try the savings calculator.

|---|---|
| Tax code and region | Scottish Income Tax, Welsh codes, emergency tax or a non-standard tax code can move the result. |
| Student loan plan | A different plan can change deductions because each plan uses its own threshold and repayment rate. |

| Tax code | HMRC tax-code changes, K codes, BR/D codes, or emergency markers can change PAYE deductions. |

The figures on this page are worked from postgraduate loan, using the values below. Open the calculator if your example salary differs.
This estimate is worked out on £35,000 annual gross. Interest rate, term, fees, deposit and the credit commitments you already have all move the result, and a lender applies its own affordability policy and credit checks on top. Treat the number as a way to see whether a repayment looks comfortable or stretched, not as an offer — and read it against your real bills, savings and any income change you expect. See how each deduction is worked out.
It starts from the question on this page, shows the useful salary assumptions, and opens PayBreakdown's calculator so gross pay, take-home pay, tax, National Insurance, pension, student loan, region, and tax-code settings can be adjusted.
