Ireland Salary inflation calculator
A pay rise only makes you better off if it beats inflation. A 3 percent raise in a year when prices climbed 5 percent is a pay cut in everything but name, because your money buys less than it did before. This calculator compares two salaries in real terms. Enter what you used to earn, what you earn now, the number of years between the two and the average inflation rate over that period, and it shows your new salary measured in the old money, the figure you would have needed just to stand still, and whether you are ahead or behind once rising prices are taken out. It is for anyone weighing up whether their pay has kept pace, comparing an old job to a new one, or judging a raise against the cost of living rather than the headline number. Inflation compounds, so even modest yearly rates stack up over several years, which is why a raise that felt generous can quietly leave you worse off.
This compares two salaries in real terms by compounding an average inflation rate over the gap between them. A rise that matches inflation leaves you standing still; only the part above inflation lifts your spending power. Use your own country average rate for the period, as headline inflation varies year to year.
How it works
- Enter your old salary and the salary you earn now.
- Put in the number of years between the two figures.
- Add the average inflation rate a year over that period; your national statistics office publishes the consumer price index it comes from.
- The tool compounds inflation across the years to find what the old salary would need to be today to match, then compares it with your current pay.
- It reports the real change as a percentage, plus your new salary expressed in the old money so you can see the spending power directly.
needed = old salary x (1 + inflation)^years; real change = new salary / needed - 1
Inflation compounds, so the price level after several years is the starting point multiplied by one plus the yearly rate, raised to the power of the number of years. Multiply your old salary by that factor to get what it would need to be today to hold the same spending power. Dividing your current salary by the same factor restates it in the old money. The real change is your current pay against the needed figure: above it you have gained ground, below it you have lost it, whatever the headline rise looks like.

What inflation does to spending power
| 2% a year for 5 years | +10.4% | pay must rise this much to match |
| 3% a year for 5 years | +15.9% | a common central-bank target is 2% |
| 5% a year for 5 years | +27.6% | a noticeable squeeze on real pay |
| 10% a year for 5 years | +61.1% | spending power erodes faster than it looks |
Worked example
You earned 30,000 three years ago and earn 33,000 now, over a period when inflation averaged 4 percent a year: prices rose by about 12.5 percent over the three years, so you would need roughly 33,745 today just to match the old 30,000. Your 33,000 falls a little short, worth about 29,337 in the old money, a real pay cut of around 2.2 percent despite the 10 percent rise on paper.
Key facts
- A pay rise that exactly matches inflation leaves your spending power unchanged; only the part above inflation is a real gain.
- Inflation compounds, so 3 percent a year is about 16 percent over five years, not 15.
- Many central banks, including the Bank of England, the European Central Bank and the US Federal Reserve, aim for inflation of around 2 percent a year.
- When pay lags inflation while tax thresholds stay frozen, more of your income can be taxed even as it buys less, an effect known as fiscal drag.
Tips
- Use the consumer price index from your national statistics office for the inflation figure, averaged over the same years as your pay change.
- Judge a job offer or a raise against inflation, not just the previous salary, so a 4 percent rise in a 6 percent year is seen for what it is.
- Over long periods even a low average rate matters, so check spending power across the whole span rather than year by year.
- Pair this with a take-home pay calculator, since tax can change the real value of a raise on top of inflation.
Frequently asked questions
Has my pay kept up with inflation?+
Enter your old and new salary, the years between them and the average inflation rate, and the tool shows whether your pay is ahead or behind in real terms. If the new salary is below the needed figure, your spending power has fallen.
What inflation rate should I use?+
Use the average annual consumer price index from your national statistics office over the same period as your pay change. For the UK that is the ONS, for the US the Bureau of Labor Statistics, for the euro area Eurostat.
Why does a pay rise sometimes feel like a pay cut?+
Because prices rose faster than your pay. If inflation outpaces your raise, the larger number on your payslip buys less than the smaller one did before, which is a real-terms cut.
How does compounding affect inflation?+
Each year inflation applies to the already higher price level, so the effect builds. Three percent a year is roughly 16 percent over five years rather than 15, and the gap widens the longer the period.
Does this account for tax?+
No, it compares gross salaries against inflation. Tax and contributions affect the take-home value of a raise as well, so use a salary calculator alongside it for the full picture.
Things to watch
- This uses a single average inflation rate; real inflation varies year to year and by what you actually buy, so treat the result as a guide.
- The figures are based on the salary numbers you enter, before tax; tax and contributions change the real value further.
- Your personal inflation can differ from the headline rate if housing, energy or food make up an unusual share of your spending.
