How to read the result
- What it means
- The displayed value is an estimate based on your inputs. It represents the calculated scenario under current assumptions, not a guaranteed amount.
- Next step
- Use the result as a starting point. Adjust parameters to compare scenarios and validate with a professional when needed.
- Calculation limits
- The model uses simplified formulas and cannot account for all variables in your specific case (local regulations, personal conditions, temporal changes).
Methodology
This calculator uses a simplified repayment model: annual repayment = max(0, annual_income - plan_threshold) × repayment_rate. Monthly repayment = annual_repayment / 12.
Plan thresholds and repayment rates vary by cohort and region. The parameters in this tool are illustrative examples based on common thresholds; always confirm the correct threshold and repayment rate for your loan on the official government pages linked in the citations.
This model does not compound interest on outstanding balances. Interest, capitalisation rules and write-off policies materially affect real repayment timelines and are not included in these estimates. Use this calculator for quick scenario comparison only.
Glossary+−
- Threshold
The annual income level above which you begin to make student loan repayments for a given plan.
- Repayment rate
The percentage of income above the threshold that is taken as repayment (commonly 9% for undergraduate plans; postgraduate rates may differ).
- Write-off
A policy that cancels remaining loan balance after a specified period or on reaching certain conditions; rules vary by plan and cohort.
- Cohort
The group of borrowers with loans issued under the same rules and dates which determine repayment thresholds and rules.
Key takeaways
This calculator provides indicative monthly and annual repayment amounts for UK student loans under different repayment plans using a simplified formula. It is intended for scenario comparison, not as a definitive repayment schedule.
Always confirm thresholds, rates and policy details on the official UK government pages linked in the citations.

Example 1 — Plan 2
Individual with £30,000 annual income, £25,000 balance on Plan 2.
Interpretation
Using threshold £27,295 and a 9% repayment rate, annual_repayment = (30,000 - 27,295) * 0.09 = £242.55; monthly ≈ £20.21. At this repayment level, years to repay (without interest) ≈ 25000 / 242.55 ≈ 103 years — illustrating the impact of interest and write-off rules not modelled here.
Example 2 — Postgraduate loan
Individual with £40,000 annual income, £10,000 postgraduate loan.
Interpretation
Using an example postgraduate threshold £21,000 and a 6% repayment rate, annual_repayment = (40,000 - 21,000) * 0.06 = £1,140; monthly = £95. Years to repay (no interest) = 10000 / 1140 ≈ 8.77 years.
Frequently asked questions
Does this include interest?
No. This calculator uses a simplified model that does not include interest accrual. Interest and capitalisation rules can significantly change repayment timelines; consult official guidance or a financial adviser for detailed modelling.
Where do thresholds and rates come from?
Thresholds and rates vary by plan and cohort. This tool uses representative example values; see the citations for official, up-to-date thresholds and rates for your loan type and region.
Can this predict write-off or tax effects?
No. Write-off terms, tax, salary changes, and other policy specifics are not modelled. Use this for approximate comparison only.
