Salary Growth Trajectory Calculator
Your salary does not grow in a straight line: it compounds. A 4% raise on $70,000 gives you $2,800 in year one, but after 10 years that same 4% is applied to a much higher base, producing $4,148. This calculator applies the standard compound future value formula to project your salary year by year and totals your cumulative earnings over the period you choose. Use it to evaluate the long-term value of a higher starting salary, a better raise rate, or an earlier promotion.

Salary growth formula
Salary(n) = Salary(0) x (1 + r)^n
Cumulative = sum of Salary(1) through Salary(n)
Where r is the annual raise rate as a decimal and n is the number of years. This is the standard compound future value formula as used in time-value-of-money analysis.
Why starting salary matters more than raise rate
- A $5,000 higher starting salary at 3% annual growth adds over $130,000 in cumulative earnings over 20 years.
- A 1 percentage point higher raise rate (e.g., 4% vs 3%) on a $70,000 salary adds roughly $250,000 in cumulative earnings over 20 years.
- Both effects compound: a higher starting salary with a higher raise rate produces an outsized long-run difference.
- Real (inflation-adjusted) salary growth should subtract the current CPI rate from your nominal raise to see purchasing-power gains.
Salary growth trajectory: frequently asked questions
What is the average annual salary increase in the US?
According to the U.S. Bureau of Labor Statistics Employment Cost Index, private-sector wages and salaries typically grow at 3 to 5 percent per year in nominal terms. Adjusting for inflation using the CPI, real wage growth has averaged closer to 1 to 2 percent annually.
How is compound salary growth calculated?
Compound salary growth uses the future value formula: Salary(n) = Salary(0) x (1 + r)^n, where r is the annual raise rate as a decimal and n is the number of years. This compounds year over year, just like compound interest.
Should I use nominal or real growth rate?
Use the nominal raise rate (what your employer offers) if you want to see your actual dollar figures. Use a real rate (nominal minus inflation) if you want purchasing power in today's dollars. The U.S. CPI inflation rate is published monthly by the Bureau of Labor Statistics.
How do promotions affect salary trajectory?
Promotions typically produce a step-change increase of 10 to 20 percent above normal annual raises. To model a promotion, run two periods: pre-promotion years with the base raise, then add the promotion bump and continue. This calculator models a constant annual rate as a baseline.
What is cumulative lifetime earnings and why does it matter?
Cumulative earnings is the sum of all salaries paid over the projection period. It matters because negotiating a higher starting salary compounds forward: a $5,000 raise today, at 3% annual growth over 20 years, adds over $130,000 in cumulative earnings.
