Total career earnings projected over a working life

The Aggregate Most People Never Calculate

A 40,000 salary held flat for 40 working years totals 1.6M in nominal earnings. With 3% annual raises the same starting salary totals 3.0M — nearly twice as much. Almost no one has a sense of this aggregate figure despite spending four decades earning it.

Why It Matters

The lifetime figure reframes individual financial decisions. A 50,000 home extension is 1.6% of 3M lifetime earnings — small in context. A 200,000 degree decision is 6.7% — large. Choices made across 40 years carry different weights than the annual budget suggests.

What the Raises Actually Buy

The raise premium (lifetime with raises minus flat) is what negotiation and career progression actually produce. On 40k start with 3% raises over 40 years, the premium is 1.4M — more than a whole second career's worth of money. The calculator makes this visible.

Run it with sensible defaults

Using current annual income of 40,000, expected career length of 40, average annual raise of 3, the calculation works out to approx 3.0M. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Current Annual Income, Expected Career Length, and Average Annual Raise — do not pull with equal force. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

How the math works

Each year's income compounds at the raise rate. Total sums across all career years. Results are estimates for illustration purposes only. The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".

Using this to recalibrate

Repeat the calculation with smaller inputs to see how much the final figure moves. That sensitivity is where the actionable insight lives — often a modest change today produces a dramatically different lifetime total.

What this doesn't capture

This is an illustration, not a prediction. The specific figure depends entirely on your inputs — change any assumption and the headline moves. The value is in the pattern it reveals, not the exact pound figure.
