Career Progression & Student Loan Calculator
Model your entire career trajectory and see exactly how salary progression affects your lifetime student loan repayments. Compare different career paths and discover whether you'll repay in full or benefit from write-off.
Thresholds, rates and write-off periods are the 2026-27 published figures[source], and a Postgraduate Loan can be modelled alongside your undergraduate plan.
Your salary in the first repayment year. Every pattern below starts here.
Age when loan repayments begin
Total undergraduate loan including interest
Steady growth plateauing around £45k
9% of everything above £29,385
Only rates Plan 2 can actually be charged are offered. Its ceiling is 6.0%[source] while the 6% cap holds.
Projection Summary
Outcome: written off
Written off
£159,095 is cancelled after 30 years, at age 51.
You repay £33,252 of it — 17.3% of everything that falls due. Voluntary overpayments here would reduce what is written off, not what you owe.

How this is worked out
(£28,000 − £29,385) × 9% = £0
Your Plan 2 repayment in year one, 2026-27 threshold. A starting salary at or below £29,385 means nothing is due at all — repayments only begin once you cross it, which on this pattern happens later in your career.
How this is worked out
£33,252 ÷ (£33,252 + £159,095) = 17.3%
The share of the debt you actually clear, as a percentage. Repaid divided by the ORIGINAL balance can exceed 100% on a long projection while money is still being written off, which is why it is not used here.
Career Salary Trajectory
Key Career & Repayment Milestones
Strategic Recommendations
£159,095 is cancelled after 30 years. A voluntary overpayment on this trajectory reduces the amount written off, not the amount you pay, so it buys nothing.
Because you do not clear it, what you repay is set by your income above the threshold, not by the size of the loan. Borrowing more would not change the figures above.
Spare money does more in a pension, an ISA, a house deposit or an emergency fund than against a balance that will be cancelled.
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.
This calculator also assumes
- Career pattern
- Moderate (Teaching, Nursing)
- Interest rate
- Modelled each year from that year's salary (4.1% in year one)
- Ceiling for Plan 2
- 6.0%
- Projection length
- 30 years
- Postgraduate Loan
- Not modelled
Growth, inflation and long-run interest figures are assumptions, not published rates. Change them and the projection changes.
Repayment thresholds are held at their 2026-27 level for the whole projection rather than grown year on year. Plan 2 is frozen at £29,385 to April 2030 and Plan 5 at £25,000 to April 2027 in any case[source]. For a projection that models the freeze and the uprating that follows it, use the total loan cost calculator.
Understanding Career Progression Impact
Why Trajectory Matters
- • Repayments are based on income above the threshold for 30 to 40 years
- • Peak salary timing affects total repayment more than starting salary
- • Early plateau careers benefit most from write-off
- • Fast-track careers usually repay in full plus interest
- • Interest compounds during low-earning years
Career Pattern Examples
- • Fast-Track: Investment banking, corporate law
- • Steady Climb: Medicine, senior engineering
- • Moderate: Teaching, nursing, public sector
- • Early Plateau: Creative fields, SME marketing
- • Late Bloomer: Entrepreneurs, academics
Using This Calculator Effectively
Try different patterns:
Compare how different career trajectories affect your lifetime repayment. The difference can be tens of thousands of pounds.
Add your postgraduate loan:
A Postgraduate Loan is repaid at the same time as your undergraduate one, at 6% above £21,000, not after it. Tick the box above to see both together.
Account for career breaks:
Time out for family, study or a career change reduces repayments. This projection assumes continuous work.
Review regularly:
Your actual career may differ from the projection. Review every few years as your path becomes clearer.
