Gross salary is the number on the offer letter. True net income is what you actually keep. The gap between the two grows substantially once you factor in commuting, and it grows in ways that are not obvious until you run the maths.
Consider a €65,000 hybrid role in Dublin requiring three days per week in the office, versus a €58,000 fully remote role. The hybrid role pays €7,000 more, a meaningful difference on paper. But after Irish income tax, USC, and PRSI, the net salary difference narrows to around €4,100. Add a typical Dublin commute (Leap card, 60-minute round trip, buying lunch) and the hybrid role's advantage shrinks to roughly €500 per year. Add the time cost of 276 annual commuting hours and the remote role wins outright.
The same logic applies in the UK. A £60,000 hybrid role versus a £54,000 remote role looks like a £6,000 advantage. After HMRC deductions, that is approximately £3,600 net. A three-day London commute on a monthly Travelcard, two stops plus a coffee each way, and a standard professional wardrobe budget can consume £4,000 to £5,000 per year in direct costs alone, before the time cost is counted.
It plays out again in Australia. A A$145,000 hybrid role in Sydney versus a A$130,000 fully remote role is a A$15,000 gross gap, which narrows to around A$9,500 after income tax and the Medicare Levy. A three-day-per-week commute on a capped Opal fare, plus meals and wardrobe, adds roughly A$3,400 a year in direct costs. Once you value the 138 annual commuting hours at the implied hourly rate, the true net advantage flips: the remote role is actually worth more, despite paying A$15,000 less on paper.
