Pay Rise Calculator (Real Terms)

When you receive a pay rise, not all of the increase reaches your pocket. The marginal rate of tax and NI on the raise determines how much you actually keep. For example, a basic-rate taxpayer loses 20% to income tax and 8% to NI, keeping 72p of each additional pound. A higher-rate taxpayer keeps only 58p.

This calculator takes your current salary and the proposed new salary, then calculates the exact change in take-home pay. It accounts for any threshold crossings — for instance, if the rise pushes you from basic to higher rate, only the portion above £50,270 is taxed at the higher rate.

The results show your old and new annual take-home pay, the gross increase, the net increase (what you actually keep) and the effective rate of deductions on the raise. This helps you negotiate salary increases with a clear understanding of the real-world impact.

UK average pay rise expectations 2026. CIPD survey 2025: median UK pay settlement 4.0% (range 3.0-5.5%). Public sector: typically 1.5-3% (constrained by budget). Tech sector: 5-8%. Finance: 4-6% + bonus growth. Inflation parity: aim for at least CPI rise (2.0-2.5% predicted 2026) to maintain purchasing power. Real pay growth (after inflation) averaged 0.4%/year UK 2010-2024 — lowest since records began. Negotiate hardest at: annual review, role change, after major project success.

Net vs gross pay rise — the tax effect. 4% gross rise on £35,000 = £1,400 gross. Income tax 20% = £280; employee NI 8% = £112. Net rise = £1,008. Effective marginal rate 28% (basic-rate band). Higher-rate trap: rise above £50,270 triggers 40% income tax + 2% NI = 42% marginal. £60k earner getting £5k rise nets only £2,900. Child Benefit High Income Charge if you cross £60,000: 1% claw-back per £200 above. Pension contribution sacrifice can recover net advantage.

How to ask for a pay rise — UK tactics. Document your impact: revenue generated, cost saved, projects delivered, awards/recognition. Research market rate: Glassdoor, LinkedIn Salary, Indeed, professional body surveys. Pick timing: after positive review, post-success, fiscal year planning (Sep-Jan). Be specific: 'I'd like to discuss salary aligned with my role and market — £40,000 to £45,000 reflects this.' Don't threaten to leave unless prepared to (counter-offers typical, 70% of 'I've been offered elsewhere' result in 10-15% raise). Get rise in writing.

Benefits beyond cash — value of non-salary perks. Pension match: 5% employer match on £40k = £2,000/year tax-free. Equivalent to £3,300 gross pay rise (40% taxpayer). Private medical insurance: £400-£1,200 (Bupa typical family); taxable benefit-in-kind 20-45%. Company car (EV salary sacrifice): saves 30-50% for higher rate. Bonus + shares + commission: average 10-30% of base salary for mid-management. Holiday: 28 days statutory; 30+ days valuable benefit. Flex schedule, WFH: hard to value but worth £5-£15k/year in commute savings and quality of life.

The compound effect of pay rises. 4% annual rise vs 2.5% over 30 years: starts £35,000. 4% rise: ends £113,500. 2.5%: ends £73,000. £40k+ difference annually at end of career. Pension proportional too — pension contributions on higher salary compound massively. Negotiate every 2-3 years minimum — every percentage point matters long-term. Job switching typically gives 15-25% rises (vs 3-5% internal) — every 4-5 years optimal frequency for career-stage moves. Career-final salary often determines retirement comfort.
