Raise Negotiation Calculator

A raise is not a one-year event, because every later increase is a percentage of a base that the raise has already lifted. On the defaults, negotiating 3,000 onto a 60,000 salary with 3% annual increases across 20 remaining working years is worth 80,611.12 in total, which is 26.87 times the raise itself. The gap starts at 3,000 in year one and reaches 5,260.52 by year twenty.

Where the extra money comes from

Compounding is doing less of that work than it looks. The same 3,000 repeated flat for twenty years, with no annual increases at all, is 60,000. Everything the 3% adds on top is 20,611.12, about a quarter of the total. The bulk of the number is simply the raise arriving twenty times, which means the years field rather than the rate field is carrying most of the weight.

Years matter more than the raise rate

The sensitivity confirms it. Measured at the defaults, a 1% change in career years remaining moves the result by 1.33%, while a 1% change in the annual raise rate moves it by 0.31%, four times less. Current salary does not enter the headline at all; it only sets the raise percentage shown in the result panel. Stretching the horizon rather than the rate is what changes the answer: the same 3,000 at 3% is worth 34,391.64 over ten years, 80,611.12 over twenty and 142,726.25 over thirty.

What rate to put in the raise field

It is asking what future increases will average, which is a labour market question rather than a personal one. The International Labour Organization publishes the Global Wage Report, which tracks real wage growth by region and country and is the closest thing to an authoritative global picture. Rates differ sharply between countries, sectors and periods, which is why the field takes a figure rather than assuming one, and why running the calculation at more than one rate says more than any single result.

Nominal and before tax

Every figure here is both. The raise is taxed at whatever marginal rate applies, and in most systems income-linked deductions rise with it too, so the amount that reaches a bank account is smaller than the lifetime figure shown. Inflation cuts the other way and roughly cancels: the raise grows alongside prices if annual increases keep pace, so the nominal gap is the honest comparison against a nominal salary, and the real-terms gap is a different calculation.

The other half of the question

Field experiments on salary negotiation give some sense of it. Cullen, Pakzad-Hurson and Perez-Truglia ran two experiments with more than 3,100 job seekers and found that a light-touch encouragement to negotiate raised both the number of attempts and the compensation gains that followed, while paying for negotiation coaching did not produce the same effect. The arithmetic here prices the outcome; the research is about whether the conversation happens at all.

What sits outside

Job changes, which reset the base entirely and are the largest single thing this cannot see; promotions that move salary in steps rather than percentages; career breaks; the possibility that annual increases stop for a period; and any part of pay that is not base salary.
