At £110K with a typical 3-day commute (£15/day transport, 60 min round trip, £5 daily meal premium, £500/yr wardrobe), your true net income is approximately £60,297 per year. Your net salary without any commute deductions would be £72,357. The commute costs you £12,060 per year in direct costs and lost time, meaning you would only need to earn £85,800 fully remotely to match this hybrid role's real value.
Assuming a 3-day hybrid schedule with a typical UK commute, you would need a remote salary of at least £85,800 to match the true net income of a £110K hybrid Penetration Tester role. This accounts for £3,260 in direct annual commute costs and £8,800 in time cost (138 hours of commuting per year valued at your hourly rate of £64/hr).
On a 3-day hybrid schedule, a Penetration Tester in UK faces approximately £3,260 in direct annual costs (transport, meals, wardrobe) plus £8,800 in opportunity cost from 138 hours spent commuting each year. Total commute impact: £12,060.
Your hourly rate is calculated by dividing your gross salary by contracted hours across 46 working weeks (accounting for statutory leave). For a £110K Penetration Tester on 37.5 hours per week, that is £64/hr. On a 3-day hybrid schedule with a 60-minute round trip, you spend 138 hours commuting per year, valued at £8,800.
A £110K Penetration Tester salary in UK is subject to Income Tax and National Insurance, leaving a net salary of £72,357 per year (£6,030/month) before any commute costs. The effective tax rate at this income level is approximately 34.2%.
Both Ireland and the UK provide statutory minimum paid leave of approximately 4 weeks. Adding bank holidays brings the typical total to around 5.6 weeks per year. Using 46 working weeks ensures that commute costs and time calculations only apply to weeks when you actually travel to the office.
