Lifetime Earnings Calculator - Career Income Forecast

The lifetime earnings calculator projects how a starting salary compounds across a career and what that path is worth in today's purchasing power. Students comparing majors, workers weighing a raise against inflation, and planners sketching retirement income can see both the headline sum of paychecks and a real-dollar total. Enter starting annual salary, the annual growth rate, career duration in years, an inflation rate, and retirement age for context. The forecast uses career duration as the number of working years; retirement age is a planning label and is not added on top of duration. Pay in year t (counting from zero) is starting salary times (1 + growth rate) to the power t. Lifetime earnings add those annual amounts. Inflation-adjusted earnings divide each year's pay by (1 + inflation rate) to the power t so early-career dollars and late-career dollars are expressed in year-zero purchasing power. Final annual salary is the last year's nominal pay. Average annual earnings equal lifetime earnings divided by the number of career years. Growth and inflation are applied once per year with no intra-year raises, bonuses, or gaps in employment. When the raise rate equals inflation, real lifetime earnings collapse toward starting salary times years, which is a useful check. When raises lag inflation, the inflation-adjusted total falls behind the nominal sum even if the headline career total looks large. Use the lifetime earnings calculator to compare a lower-paying path with faster growth against a higher starting salary that barely keeps up with prices, or to see how a ten-year versus forty-year horizon changes the average. The model ignores taxes, benefits, overtime, career breaks, Social Security, and defined-benefit pensions. It also ignores unemployment and job-switching premia. Retirement age does not change the arithmetic unless you shorten or lengthen career duration to match it. If you start at 25 and retire at 65, enter 40 years rather than expecting the calculator to subtract ages. Treat the result as a scenario, not a promise of future pay. Labor markets, health, and occupation-specific wage curves can bend the path. For education or relocation decisions, combine the lifetime earnings calculator with living costs, debt service, and a tax view. Re-run when the raise assumption or the inflation outlook changes, and keep nominal and real figures side by side so a large future salary is not mistaken for large purchasing power.
