Why a one-off increase is not one-off
The figure above is large because a starting salary is the base everything else is calculated from. Percentage rises compound on it, bonuses are usually a percentage of it, pension contributions are a percentage of it, and the next employer will ask what it is.
So a difference at hire does not stay that size — it widens every year. That is also why the same negotiation is worth substantially more early in a career than late: there are more years for it to compound over.
What actually moves an offer
- A specific, sourced number. A range from published pay data or a legally required range in a job posting is far harder to dismiss than a general sense of being underpaid.
- Timing. The leverage is highest after an offer and before acceptance. It falls sharply afterwards.
- What the increase costs them. A few thousand on a salary is small against the cost of restarting a hiring process that has already run for months.
- Everything that is not base pay. Where the salary band is genuinely fixed, signing bonus, equity, holiday, title, review date and remote arrangements are often not.
On the risk of asking
Offers are very rarely withdrawn over a polite, reasoned counter — employers generally expect one, and many leave room for it. The more common outcome by a wide margin is accepting a first offer that had room in it.
Two things make a counter easy to say yes to: name a figure rather than asking what is possible, and give the reason alongside it. "Based on the published range for this role and my experience with X, I was targeting Y" is a different conversation from "is there any flexibility".
What this model simplifies
It assumes steady percentage rises and continuous employment, which is smoother than most careers. Career breaks, job changes and promotions all move the line, generally by more than the negotiation itself — a change of employer is usually the largest single pay increase most people ever get.
It also works in gross pay. What reaches you depends on tax bands, and where a rise crosses a threshold, the net gain is smaller than the gross one.

What changes in Ireland
- Ireland has an unusually sharp jump into the higher rate — 40% from roughly €44,000 for a single person, plus USC and PRSI on top. A raise crossing that point is worth much less than the gross figure suggests.
- USC is a separate charge with its own bands, so the true marginal deduction on a pay rise is meaningfully above the headline 40%.
- Pension contributions get relief at the marginal rate within age-related limits, so redirecting a raise into a pension is often worth more than taking it as cash for anyone above the higher-rate threshold.
- Joint assessment lets a married couple transfer part of the standard rate band, which can be worth over a thousand euro a year where one partner earns much less.
