Combined Repayment Calculator: Undergraduate and Postgraduate Loans
Repaying an undergraduate loan and a Postgraduate Loan at the same time? This calculator shows each deduction and the total that leaves your pay. You repay 9% above your undergraduate threshold and 6% above £21,000 on the Postgraduate Loan. Figures are the 2026-27 thresholds and rates[source].
Only have one loan? For your payoff date, write-off date and total cost, use the main student loan calculator. For the payslip figure on one plan, use the monthly repayment calculator. Not sure which plans apply to you? Our student loan plans explained guide covers how to identify each one before you combine them here.
Combined Loan Repayment Calculator
Each loan is deducted separately, against its own threshold and its own rate. Repayments depend on your income, never on how much you owe.
Your Details
Undergraduate loan
£29,385 threshold, 9% of anything above it (2026-27).
Postgraduate Loan
£21,000 threshold, 6% of anything above it (2026-27). A Master's or Doctoral Loan is deducted on top of any undergraduate plan, against its own lower threshold[source].
There is no balance field here on purpose: an income-contingent repayment is the same whether you owe £5,000 or £95,000. To see what the balance does over a lifetime, use the total loan cost calculator.
£112.11 a month
Two loans are deducted together: £1,345.35 a year in 2026-27, about 3.8% of your gross pay.
Above £29,385 both deductions run, so every extra £1,000 of pay costs £150 in student loan.

Plan 2 (2012–2023)
£29,385 threshold, 9% above it
£42.11
How this is worked out
(£35,000 − £29,385) × 9% ÷ 12 = £42.11
Plan 2 (2012–2023), 2026-27. Annual: £505.35.
Postgraduate Loan
£21,000 threshold, 6% above it
£70
How this is worked out
(£35,000 − £21,000) × 6% ÷ 12 = £70.00
Postgraduate Loan, 2026-27. Annual: £840.
Your combined marginal rate
15% of income above £29,385
9% on the undergraduate loan plus 6% on the Postgraduate Loan. Each is measured against its own threshold, so below £29,385 only one deduction is running.
Rates, assumptions and sources
Every figure below is the 2026-27 published figure, read from this site's single source of truth at page-render time[source]. The 6% Plan 2 and Postgraduate interest cap covers the 2026/27 year only and is not assumed to continue[source].
| Plan | Threshold | Rate | Interest | Written off | Threshold freeze |
|---|---|---|---|---|---|
| Plan 2 | £29,385[source] | 9% | 4.1% to 7.1% by income, capped at 6% for 2026-27[source] | 30 years[source] | Frozen at £29,385 until April 2030 |
| Postgraduate Loan | £21,000[source] | 6% | 7.1%, capped at 6% for 2026-27[source] | 30 years[source] | Uprated annually — no freeze announced |
Write-off is counted from the April after the course ends, not from the course-end date itself, and the Plan 2 interest bands (£29,385 lower, £52,885 upper) are frozen alongside the Plan 2 repayment threshold.

Frequently Asked Questions
How do multiple student loan plans work together?
You repay each one at the same time, once you earn above its own threshold. Undergraduate loans take 9% of income above the plan threshold and postgraduate loans take 6% above £21,000, so above both you pay 15% of the excess[source].
Can I have a Postgraduate Loan with no undergraduate loan?
Yes. If your undergraduate course was funded some other way, or you have already cleared that loan, choose “None” for the undergraduate plan above and only the postgraduate deduction is applied.
Do I make separate payments for each loan?
No. All student loan repayments are deducted from your salary by your employer. The Student Loans Company then allocates what it receives across your loans, according to each one's threshold and rate.
