2026/27 5-plan comparison
| Plan | Threshold | Rate | Write-off | Interest | Who |
|---|---|---|---|---|---|
| Plan 1 | £26,900 | 9% | 25 yr | Lower of BoE base rate + 1% OR RPI | Pre-Sept 2012 England + Wales, all NI starters |
| Plan 2 | £29,385 | 9% | 30 yr | RPI + up to 3% (income-based sliding scale) | Sept 2012 - Aug 2023 England + Wales starters |
| Plan 4 | £33,795 | 9% | 30 yr | RPI | Pre-2007 + post-2007 Scottish starters |
| Plan 5 | £25,000 | 9% | 40 yr | RPI only (no income-based variation) | Sept 2023+ England starters (post-Augar reforms) |
| Postgrad | £21,000 | 6% | 30 yr | RPI + 3% | Postgraduate loans (Masters / PhD) since 2016 |
Plan 5 represents biggest reform since 2012 - lower threshold + longer write-off makes it functionally a graduate tax for most borrowers. RPI-only interest is genuinely favourable vs Plan 2's RPI + 3%.
Frequently asked questions
What is Plan 5 Student Loan and who does it apply to?
Plan 5: new student loan plan introduced for English students starting university courses from 1 September 2023. Statutory basis: Higher Education and Research Act 2017 + Student Loans Regulations 2009 (amended). Outcome of 2019 Augar Review. Key differences from Plan 2: lower repayment threshold (£25,000 vs Plan 2's £29,385); longer write-off period (40 years vs Plan 2's 30); interest rate capped at RPI inflation (vs Plan 2's RPI + up to 3% sliding scale). Repayment rate: 9% of income above £25,000 threshold - SAME as Plan 2 / Plan 1 / Plan 4. Who has Plan 5: English-domiciled students who started UK undergraduate courses on or after 1 September 2023. NOT for: Welsh / Scottish / Northern Irish starters (Plans 2/4/1 respectively), pre-2023 English starters (Plan 2), postgraduate (separate Postgrad loan plan). Worked example - £30,000 salary Plan 5 borrower: monthly threshold £2083 (~£2,083). Earnings above: £30,000/12 - £2,083 = £417/month. Repayment 9% × £417 = £37.50/month = £450/year. Comparison vs Plan 2: same £30k earner on Plan 2 would only pay 9% of (£30k - £29,385) = ~£55/year. Plan 5 = 8x higher repayments at typical graduate salary.
How is Plan 5 different from Plan 2?
Three fundamental changes Plan 2 → Plan 5: (1) Lower repayment threshold: £25,000 vs £29,385 (Plan 2). Means Plan 5 borrowers start repaying at a £4,000+ lower income level. Critical impact - more graduates make repayments + repay for longer. (2) Longer write-off period: 40 years vs 30 years (Plan 2). Plan 5 graduates pay 10 more years before any remaining balance is written off at retirement-age-ish (typically late 50s/60s). (3) Interest rate capped at RPI: Plan 5 interest never exceeds RPI inflation. Plan 2 has RPI + up to 3% sliding scale based on income. Real-terms implication of Plan 5 RPI cap: balance grows in nominal terms but stays flat in real terms. NO real interest. Different from Plan 2 where higher earners faced 3% real interest = compound interest pile-up. Overall financial impact: Plan 5 is GENERALLY more expensive for low-mid earners due to lower threshold + longer write-off. Plan 5 is FAVOURABLE for high earners (capped RPI interest means they don't accumulate excess interest before repaying). Lifetime cost modelling: average Plan 5 graduate pays £25,000-£45,000 in total repayments vs Plan 2 average £18,000-£32,000. Higher earners may actually pay less under Plan 5 because they were going to repay full balance anyway + RPI cap helps. Behavioural effect: Plan 5 is closer to a graduate tax than Plan 2's loan structure.
How is Plan 5 interest calculated?
Plan 5 interest: RPI inflation only. No sliding scale based on income. No premium above RPI. Set in September each year using RPI from preceding March (Student Loans (Repayment) Regulations 2009 Reg 39). Cap: actual interest may be capped at "prevailing market rate" determined by HM Treasury (Schedule 1 paragraph 1 Higher Education and Research Act 2017). 2024 saw temporary caps to prevent extreme interest spikes when RPI hit 11%+. 2026/27 interest rate: estimated 3-4% (March 2026 RPI). Subject to ongoing review. Why this matters: real value of debt doesn't grow under Plan 5. £45,000 loan today maintains £45,000 of real purchasing power throughout repayment. Plan 2 borrowers face compound real-interest growth that pushed many balances ABOVE original loan amounts after 10-15 years. Worked example - £40,000 Plan 5 loan at 4% RPI year 1: balance grows £1,600. Repayments at 9% of (£30k - £25k) = £450/year. Net balance growth £1,600 - £450 = £1,150. Balance after year 1 = £41,150. Continues until repayment exceeds interest growth. Compare to Plan 2 historical: 2022/23 borrowers faced 7%+ interest on Plan 2 - balance grew £4,200/year on same £40k loan. Repayment £450 = net growth £3,750. Plan 2 graduates often spent years paying down accruing interest before touching principal.
When does Plan 5 student loan write off?
40 years after the April following graduation/leaving course. Statutory basis: Schedule 1 paragraph 7 Higher Education and Research Act 2017 + Section 22 Teaching and Higher Education Act 1998 (carried through). Worked example: graduate 2027 (1st Sept 2023 starter, 4-year course). Write-off year: April 2068 (40 years from April 2028). Implication: most graduates approaching/in retirement when loan written off. Vs Plan 2 30-year write-off: same graduate would have loan written off April 2058 = 10 years earlier. Significant difference. Death: loan written off on death regardless of write-off period (Schedule 1 paragraph 9 Higher Education and Research Act 2017). Beneficiaries don't inherit student loan debt. Disability / permanent incapacity: write-off possible under specific conditions. Apply via Student Loans Company. Bankruptcy: student loan typically survives bankruptcy (Insolvency Act 1986 Section 281(8)). Cannot escape via bankruptcy. Emigration: still liable but repayment rates may be at different thresholds via Overseas Income Assessment. Annual declaration of overseas income to SLC required. Strategic implications: graduates on Plan 5 with low-to-mid earnings throughout career will likely have balance written off at year 40. High earners more likely to repay in full before write-off. Calculate expected lifetime repayment vs balance to decide overpayment strategy.
Should I overpay Plan 5 student loan?
Generally NO - unless very specific circumstances. Why not overpay: (1) Real interest = zero. Plan 5 only charges RPI inflation. Your £1 today repays £1 of real value tomorrow. No "saving" by paying early. (2) Write-off after 40 years: any unpaid amount disappears. Overpayment = paying for nothing if you were going to be written off. (3) Opportunity cost: £1,000 invested in ISA at 5% return over 40 years = ~£7,000. Same £1,000 used to overpay loan = saves maybe £40 in real interest over 40 years. Investment dominates. (4) Cash flow flexibility: keeping money invested rather than paying loan = more flexibility for emergencies, house deposit, etc. WHEN overpayment makes sense: (a) Very high income - if you'll comfortably repay full balance + then continue earning, marginal overpayment saves a small amount of real interest; (b) Approaching write-off - if a single overpayment can finish the loan ~1 year before write-off, may make sense to avoid further repayments; (c) Psychological / debt-aversion - if loan stress affects wellbeing, overpaying for peace of mind is valid (even if mathematically suboptimal). Maximum efficient repayment: just standard 9% deduction is mathematically optimal for vast majority. Don't overpay - invest instead in ISA / pension. Sense check: this is opposite of advice for high-interest credit card / mortgage debt where overpayment makes huge sense. Student loan is unique - subsidised interest + write-off = treat differently.
How does Plan 5 affect job decisions + salary negotiation?
9% above £25k threshold = effective marginal tax rate increase for graduates. Combined marginal rates: basic-rate earner already pays 20% IT + 8% NI = 28% on each £ above £12,570. Add 9% Plan 5 = 37% effective. Higher-rate earner: 40% IT + 2% NI + 9% Plan 5 = 51%. Above £125k: 45% IT + 2% NI + 9% Plan 5 = 56%. Salary negotiation implication: £1k pay rise = ~£630 net (basic-rate) or ~£500 (higher-rate). Plan 5 makes pay rises noticeably less impactful than for non-Plan-5 colleagues. Bonus tax efficiency drop: bonus that triggers Plan 5 repayment = 37%+ deducted. Salary sacrifice into pension recovers fully (sacrificed pay doesn't count toward Plan 5 threshold). Pension sacrifice tax stack: basic-rate worker sacrificing £1k pension = saves 20% IT + 8% NI + 9% Plan 5 = 37% total relief. Higher rate: 51%. Job offer assessment: comparing £45k vs £50k salary - £5k extra = 45% Plan-5-eroded = £2,750 net. Not bad but worse than non-Plan-5 colleague's £3,150 (just 37%). Self-employed transition: same 9% Plan 5 applies to self-employed profits above £25k via SA reconciliation. Class 4 NI 6% + IT 20% + Plan 5 9% = 35% on profit £12,570-£50,270. Strategic implication: Plan 5 graduates particularly benefit from pension sacrifice + ISA / LISA strategies that reduce taxable income at source.
How does Plan 5 interact with self-employment + dividends?
Plan 5 9% applies to ALL income types above £25k threshold - employment, self-employment, dividends, rental. Employment: deducted at source via PAYE based on tax code. Self-employment: declared on SA + 9% × (profit - £25k) added to SA bill. Dividends: 9% × (dividend income above any unused threshold space) added via SA. Worked example - director with £20k salary + £30k dividends + £15k SE profit: total income £65k. Above £25k threshold by £40k. Plan 5 repayment 9% × £40k = £3,600. Important - PAYE only deducts on salary portion: director's £20k salary is BELOW £25k threshold = £0 deducted at source. The £3,600 owed surfaces at SA reconciliation = lump sum demand in January. Strategy for Plan 5 directors: budget for the SA Plan 5 liability throughout year. Many directors caught out by ~£3-5k Plan 5 bill at year-end. Compare to non-Plan-5 director: same income structure pays £0 student loan. Plan 5 is meaningful cost for graduate directors. Self-employed Plan 5 mitigation: pension contributions reduce taxable profit AND the Plan 5 base. £10k SIPP contribution = £900 less Plan 5 owed at 9% rate. BTL landlords on Plan 5: rental income subject to 9% above £25k threshold. Section 24 mortgage interest restriction NOT applied to Plan 5 calc - based on full rental profit before mortgage credit. Can create cash flow issues.
Multiple plan combinations - undergraduate + postgraduate?
Common combination: undergraduate Plan 5 (post-Sept 2023) + Postgraduate Loan (Masters / PhD). Postgraduate plan: £21,000 threshold + 6% rate + 30-year write-off + RPI + 3% interest. Combined repayment: both plans deducted simultaneously above respective thresholds. Worked example - £35,000 salary graduate with both Plan 5 + Postgrad: Plan 5: 9% × (£35k - £25k) = £900. Postgrad: 6% × (£35k - £21k) = £840. Total student loan deduction: £1,740. Plus 20% IT + 8% NI + standard PAYE = effective combined marginal rate ~43% on each £ above thresholds. Order of priority: HMRC deducts both plans simultaneously - no priority. Both calculated independently then combined. Same applies for other combinations: Plan 1 + Postgrad, Plan 2 + Postgrad, Plan 4 + Postgrad. Older undergraduate plans can combine with Postgrad. Cross-plan undergraduates: rare but possible if studied multiple courses across rule changes. Generally only ONE undergraduate plan applies based on last course start. International student return scenarios: UK student studied abroad with Plan 5 loan + later took Postgrad in UK = both apply. Total cost modelling for combined plans: average Postgrad + Plan 5 borrower pays £55,000-£90,000 over lifetime. Substantial graduate tax burden. Mitigation: career planning toward higher-earning roles to repay sooner + reduce write-off period exposure.
How does emigration affect Plan 5 repayments?
Emigration does NOT cancel student loan. Statutory basis: Schedule 2 Part 2 Student Loans (Repayment) Regulations 2009. Annual income declaration to SLC: emigrants must declare worldwide income to Student Loans Company annually + repay at modified thresholds based on country of residence. Threshold adjustment: SLC sets country-specific thresholds based on cost of living comparison to UK. E.g., USA threshold higher than UK; India threshold lower. Updated April each year. Repayment calculation: 9% above the adjusted country threshold. Paid directly to SLC (no PAYE collection abroad). Worked example - £50,000 USD salary in USA (USD threshold ~£35,000 GBP equivalent): Plan 5 repayment 9% × ($50,000 - $35,000) ≈ £1,100 - £1,500/year. Paid quarterly direct debit to SLC. Non-compliance consequences: if emigrant doesn't declare or pay, SLC switches to "default rate" = highest band of repayments calculated on highest assumed income. £5,000+/year possible if you're a £100k+ earner not declaring properly. Plus arrears collection if you return to UK. Returning to UK: re-enter PAYE deduction system. Outstanding arrears collected via tax code adjustment if uncollected. Permanent emigration + write-off: still 40-year write-off applies. If you never return + never pay, debt written off at year 40. But "default rate" applied if not declaring properly = potentially much higher amounts than actual income suggests. Strategic advice: maintain SLC notification + annual declarations even when abroad. Reduces risk of default-rate assessment.
Is Plan 5 fair compared to older plans?
Subject of significant debate. Arguments Plan 5 is HARSHER than Plan 2: (a) Lower threshold (£25k vs £29.4k) means more graduates repay + repay more; (b) 40-year write-off vs 30 years means longer repayment burden into retirement age; (c) Estimated 70%+ of graduates will repay full balance + still face write-off (vs Plan 2's ~30% repay-in-full rate); (d) Acts more like graduate tax than a loan. Arguments Plan 5 is FAIRER than Plan 2: (a) RPI-only interest cap prevents compound interest "trap" Plan 2 graduates faced (where balance grew faster than repayments for years); (b) No income-based interest scaling means high earners aren't penalised with 3% real interest; (c) Lifetime cost for mid-earners actually LOWER than Plan 2 because they avoid years of compound interest; (d) Reflects political reality that graduate skills should be partly self-financed. HM Treasury modelling: net public sector subsidy on student loans REDUCED under Plan 5 (more graduates repay in full) but individual graduate burden INCREASED particularly for lower-mid earners. Universities + students associations: NUS + UCU + many universities oppose Plan 5 as deterrent to higher education. 2024 political review: Labour government reviewing Plan 5 design as part of broader higher education funding reform. Possible changes 2027+ - watch government announcements. For current Plan 5 borrowers: maximise earnings + minimise tax-base income (pension / sacrifice) to manage 9% impact. Treat as graduate tax not investment debt.
When do I start repaying Plan 5?
Repayments start in April following graduation (or April following course end if didn't graduate). Statutory basis: Schedule 1 paragraph 4 Higher Education and Research Act 2017. Worked example: graduated July 2027 (1st Sept 2023 starter, 4-year course). First repayment month: April 2028. NOT triggered by: graduation date itself - the following April applies. NOT triggered by employment start - even if you start work immediately. NOT triggered by interim earnings - working summer jobs during studies doesn't trigger Plan 5 deductions. Mid-course employment: if you work during course (summer / placement year) earning above threshold, Plan 5 does NOT deduct. Only from April following course end. Tax code change at repayment start: HMRC notified by Student Loans Company. PAYE tax code updates to "SL1" suffix or similar to flag student loan deduction. Confirm via Personal Tax Account at gov.uk/personal-tax-account. Adjusting tax code mid-year: if you start new job mid-tax-year after April repayment start, ensure new employer is notified of Plan 5 status (P45 / starter checklist Q4-5). Self-employed graduates: register for SA + Plan 5 declared on first SA return covering the year repayments start. Switching plans: if you have Plan 2 from undergrad + Plan 5 from continuing course (unusual scenario), HMRC deducts under both rules. SLC handles the priority.
How can I check my Plan 5 balance + payment history?
Student Loans Company online account: register at studentloanrepayment.co.uk. View: current balance, payment history, interest applied, projected write-off date. Monthly statements: SLC sends paper statements quarterly (or monthly online). Shows deductions made + interest added + balance. HMRC Personal Tax Account: gov.uk/personal-tax-account shows annual student loan deductions via PAYE. Tax code letter: HMRC's "P2" tax code notice shows whether SL1 / SL2 / SL3 / SL4 / SL5 (plan-specific) suffix applies. Annual tax year-end: P60 from each employer shows total student loan deducted in the tax year. Reconcile against SLC balance. Plan vs amount discrepancy: occasional issues where HMRC deducts wrong amount due to incorrect plan code at employer. Report to Student Loans Company + correct via employer / P45. SA reconciliation: if you file Self Assessment, student loan position consolidated annually. Any overpayment refunded; underpayment added to SA bill. Settlement quote: SLC will provide a "settlement amount" if you want to repay in full. Useful for assessing actual liability vs accruing-balance projection. Important - SLC settlement quote vs HMRC view: SLC quote is final balance; HMRC quote may differ slightly due to in-year timing. For employers: employer payroll software handles plan deduction automatically when plan code provided. Errors usually traceable to wrong starter declaration or P45 transfer issues.
