Lifetime Earnings Calculator
Estimate how much you will earn over your whole career from your starting salary, average yearly raise and years of work — in total and in today’s money after inflation.
How it works
salary in year k = starting salary × (1 + raise)^(k − 1) · lifetime earnings = Σ salaries = start × ((1 + raise)ⁿ − 1) ÷ raise · in today’s money: each year ÷ (1 + inflation)^(k − 1)
Lifetime earnings add up every year’s salary over a career, growing with your average raise. Because the sum is a geometric series, small differences in the yearly raise compound into large differences over 30–40 years. The figure in today’s money removes inflation so it can be compared with prices now. Studies such as the US Social Security Administration’s research on education and lifetime earnings use the same idea to compare careers and degrees.
Worked example
Starting at $45,000 with 3% average raises for 40 years, total lifetime earnings are $3,393,057, or $1,982,294 in today’s money with 2.5% inflation. The final-year salary (year 40) is $142,516 — $54,404 in today’s money — and the average yearly salary is $84,826.

Frequently asked questions
How do I calculate my lifetime earnings?
Add up your salary for every working year. With a steady raise r, the total is start × ((1 + r)ⁿ − 1) ÷ r: $45,000 for 40 years at 3% is about $3.39 million.
How much does the average person earn in a lifetime?
It varies widely by country, education and occupation. US Social Security research puts median lifetime earnings of workers with a bachelor’s degree well above those with only a high-school diploma; use your own salary path for a personal figure.
Why show lifetime earnings in today’s money?
A dollar earned in 30 years buys less than a dollar today. Dividing each year’s pay by cumulative inflation makes the total comparable with today’s prices.
How much difference does a 1% higher raise make?
Over 40 years, raising the average raise from 3% to 4% on a $45,000 start adds roughly $880,000 in nominal earnings — the power of compounding.
