Is your pay rise actually a pay rise?

The number that matters is the real one

A pay rise has two numbers. The nominal rise is what the letter says — three percent, five percent, whatever was agreed. The real rise is what happened to your purchasing power, and it is the only one that changes what your salary buys.

If prices rose four percent over the same period and your salary rose three, you can afford less than you could before. The bank balance is larger and the shopping is more expensive by more than the difference. That is a pay cut, delivered as a pay rise, and it is the most common form a pay cut takes because almost nobody has their salary reduced outright.

This is why the standard corporate "cost of living adjustment" deserves scrutiny rather than gratitude. An adjustment that matches inflation holds you exactly level — it is not a rise at all, it is the absence of a cut. A rise is what happens above that line.

The practical consequence is that the question "is this a good rise" cannot be answered from the percentage alone. Three percent was generous in a year of one percent inflation and a real-terms cut in a year of six. The same number means opposite things in different years, which is precisely why quoting it without context is so common.

Why you divide instead of subtracting

The obvious way to combine the two figures is to subtract: five percent rise minus three percent inflation equals two percent real. That is close enough at small numbers and progressively wrong as the numbers grow.

The correct calculation divides. Real change is (1 + rise) ÷ (1 + inflation) − 1. At five and three, that gives 1.05 ÷ 1.03 − 1, which is about 1.94 percent rather than 2 — a small difference that does not matter much.

Now try a period of high inflation. A twelve percent rise against ten percent inflation subtracts to two percent. Divided, it is 1.12 ÷ 1.10 − 1, which is about 1.82 percent. The error is now nearly a fifth of the entire real gain. At twenty and eighteen percent the gap is wider still.

The reason is that inflation acts on the new salary, not the old one. Your raised salary is spent at raised prices, so the two effects compound against each other rather than lining up for subtraction. It is the same reason a fifty percent gain followed by a fifty percent loss does not return you to where you started.

What to compare an offer against

Beating inflation is the floor, not the target. There are three separate benchmarks worth checking, and they answer different questions.

The first is inflation over the period since your last rise — not the current annual rate. If it has been eighteen months, the relevant figure is cumulative inflation over eighteen months, which is meaningfully larger than the headline annual number. Comparing an eighteen-month rise against a twelve-month inflation figure systematically flatters the offer, and it is an easy mistake to make because the annual rate is the one that gets published.

The second is the market rate for your role. Internal rises are typically calculated as a percentage of your existing salary, which anchors every future rise to what you were paid when you joined. Market rates are set by what employers currently pay to hire. The two drift apart, which is the entire mechanism behind the observation that changing jobs often pays better than staying — not because loyalty is punished deliberately, but because a percentage of a stale number stays stale.

The third is your own trajectory. A rise that matches inflation every year means your real salary in year ten is identical to year one, despite a decade more experience. Whether that is acceptable is a judgement, but it should be a conscious one rather than something discovered in retrospect.

What the percentage hides

A percentage is a poor unit for making a decision, because it obscures both the amount and what the amount is for.

Convert it to money first. Three percent on fifty thousand is fifteen hundred a year, about a hundred and twenty-five a month before tax, and perhaps eighty after. Whether that is worth a difficult conversation is much easier to judge as eighty a month than as three percent — and the answer is sometimes yes and sometimes clearly not.

Then check the hours. A rise accompanied by an expanded role or longer hours may reduce your effective hourly rate even while the salary rises. Salary divided by actual hours worked is the number that tells you whether the deal improved, and it frequently disagrees with the headline. Someone moving from forty to fifty hours for a ten percent rise has taken a substantial cut per hour.

Finally, remember the rise compounds. Every future percentage rise is calculated on the new base, and so is any pension contribution set as a percentage of salary. A single percentage point at thirty is worth considerably more over a career than the annual amount suggests, which is the strongest argument for negotiating early rather than accepting that the difference is small in absolute terms this year.

The years to double, both ways

The rule of 72 makes both halves of this comparison legible. Divide 72 by a growth rate and you get the years until it doubles.

Applied to salary: a career of three percent rises doubles your nominal pay in about twenty-four years. Applied to prices: four percent inflation doubles them in about eighteen. Run both and the picture is stark — prices double six years before your salary does, and the gap keeps widening. No single year of that felt like a cut.

Applied to a genuine real rise, it is more encouraging. Consistently beating inflation by two percentage points doubles your real purchasing power in about thirty-six years, which is roughly a working life. Beating it by four halves that to eighteen. The difference between those two careers is two percentage points a year, negotiated repeatedly.

That is the argument for treating every rise as a compounding decision rather than an annual event. The individual conversation is about a modest monthly amount and feels barely worth having; the sequence of them decides what a career is worth. Both facts are true, and only one of them is visible at the time.
