Pay rise from GBP 40,000 to GBP 45,000 with Plan 2

Scenario

A move from £40,000 to £45,000 produces a reliable £300/month net gain for most employees. For Plan 2 student loan borrowers, the same raise also increases loan repayments — because the 9% charge applies to the higher salary in full. This page shows both the tax and NI picture and the Plan 2 impact, so you know the precise net gain before the new salary begins.

Take-home pay at £40,000 (with Plan 2)

The personal allowance is £12,570. Taxable income = £40,000 − £12,570 = £27,430. The Plan 2 repayment threshold is £27,295.

| Deduction | Calculation | Annual amount | |---|---|---| | Income tax | £27,430 × 20% | £5,486 | | Employee NI | £27,430 × 8% | £2,194 | | Plan 2 repayment | (£40,000 − £27,295) × 9% = £12,705 × 9% | £1,143 | | Total deductions | | £8,823 | | Annual take-home | £40,000 − £8,823 | £31,177 | | Monthly take-home | £31,177 ÷ 12 | £2,598 |

Take-home pay at £45,000 (with Plan 2)

Taxable income rises to £45,000 − £12,570 = £32,430. The £45,000 salary is still well below the higher-rate threshold of £50,270, so tax and NI remain at basic rate. The Plan 2 repayment increases because the salary is higher.

| Deduction | Calculation | Annual amount | |---|---|---| | Income tax | £32,430 × 20% | £6,486 | | Employee NI | £32,430 × 8% | £2,594 | | Plan 2 repayment | (£45,000 − £27,295) × 9% = £17,705 × 9% | £1,593 | | Total deductions | | £10,673 | | Annual take-home | £45,000 − £10,673 | £34,327 | | Monthly take-home | £34,327 ÷ 12 | £2,861 |

The gain from the raise

| | Before (£40k, Plan 2) | After (£45k, Plan 2) | Increase | |---|---|---|---| | Annual take-home | £31,177 | £34,327 | £3,150 | | Monthly take-home | £2,598 | £2,861 | £263 |

The £5,000 gross raise delivers £3,150 net per year, or £263 per month. You keep 63% of each extra pound.

Where the £5,000 raise goes

It helps to see the full deduction stack on the raise itself, not just the before-and-after snapshots.

| Deduction on the £5,000 raise | Rate | Amount | |---|---|---| | Income tax | 20% | £1,000 | | Employee NI | 8% | £400 | | Plan 2 repayment | 9% | £450 | | Total deductions on raise | 37% | £1,850 | | Net gain from raise | | £3,150 |

The tax and NI alone would leave you with £3,600 — the same result as the Plan 2-free version of this raise. The Plan 2 charge adds another £450 of deductions, reducing the net gain to £3,150.

Comparing the same raise with and without Plan 2

| | Without Plan 2 | With Plan 2 | Difference | |---|---|---|---| | Net annual gain | £3,600 | £3,150 | £450 | | Net monthly gain | £300 | £263 | £37 | | Effective retention rate | 72% | 63% | 9 percentage points |

The £450 annual difference — £37/month — is the Plan 2 cost of the raise. It is not negligible, but the raise still clearly improves take-home pay and is worth accepting.

Why this matters for negotiation

If you are negotiating a salary move and have a Plan 2 loan, the gross figure is a less reliable guide to your cash gain than it is for non-borrowers. A raise that looks like £5,000/year actually delivers £3,150 in spendable cash — 37% less than the headline. Knowing that number before the negotiation means you can make a more grounded assessment of whether the offer meets your practical needs, or whether it is worth pushing for a higher gross figure to compensate.
