SA Unearned Income Student Loan Calculator
Understand the critical £2,000 unearned income threshold and its impact on student loan calculations. Dividends, property income, and other unearned income can trigger significant SA payments.
See our guide to PAYE vs Self Assessment student loans for how these two systems interact when you have both employment and unearned income.

Quick Summary
Outcome: all unearned income is counted
All £23,000 of unearned income counts
It costs you £1,675 of student loan, part of a £1,675 balancing payment due 31 January 2028.
The £2,000 allowance is all-or-nothing on the total. Once the total passes it, every pound counts — not just the excess.

Cost of the unearned income

After £0 deducted through PAYE
How this is worked out
£25,000 + £23,000 = £48,000
Earned income plus every pound of unearned income, because £23,000 is over the £2,000 allowance.
How this is worked out
£1,675.35 − £0 = £1,675.35
The balancing payment, due 31 January 2028. Student loan repayments are not included in payments on account. They are collected once a year, with the balancing payment on 31 January. Your income tax and Class 4 NIC payments on account are worked out without them.
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 |
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.

Understanding Unearned Income Student Loans
The £2,000 Cliff Edge
- • All-or-nothing rule: not a gradual threshold
- • £1,999 unearned = £0 student loan impact
- • £2,001 unearned = ALL £2,001 included
- • Can create massive liability for small income increase
- • Critical for dividend and property planning
What Counts as Unearned
- • Dividend income (before dividend allowance)
- • Property rental profits
- • Pension income
- • Interest from savings
- • Investment income
Strategic Planning Examples
Limited company director:
Taking £12,570 of salary and £40,000 of dividends puts £52,570 into the student loan calculation — the dividends are over £2,000, so all of them count — and produces £2,087 of Plan 2 liability with nothing collected through PAYE. Consider whether a higher salary, with the repayment spread across the year through payroll, suits your cash flow better.
Property investor:
Rental profit counts as unearned income. Your £8,000 of rental profit is part of the total that has crossed £2,000, so every pound of unearned income is charged, not just the excess. Consider the timing of rental income and expenses around that line.
Threshold management:
If close to £2,000, small adjustments in timing can save significant amounts. However, don't let the tail wag the dog - overall tax efficiency matters more than just student loan optimization.
