Lifetime Earnings Calculator
From current age, retirement age, current salary and annual raise, estimate total lifetime earnings.
Input Data
Results
At a glance:Lifetime earnings estimates the total salary from now to retirement. Remaining years n = retirement age − current age; assume salary grows by a fixed rate g each year and sum the yearly salaries. If g ≠ 0 the salaries form a geometric series: lifetime = current × [(1+g)^n − 1] ÷ g; if g = 0 it simplifies to current × n. It reveals the career's economic value for retirement planning, life insurance and study/job-change decisions. This is pre-tax nominal; entering the real raise (nominal minus inflation) gives today's purchasing power.
Formula
Remaining working years n = retirement age − current age.
Raise g ≠ 0: lifetime earnings = current × [(1+g)^n − 1] ÷ g.
Raise g = 0: lifetime earnings = current × n; average = lifetime ÷ n.
$$n = \text{RetirementAge} - \text{CurrentAge}$$$$g \ne 0:\ \text{Lifetime} = S_0 \times \dfrac{(1 + g)^{n} - 1}{g}$$$$g = 0:\ \text{Lifetime} = S_0 \times n,\quad S_0 = \text{current salary}$$How to Use
- Enter your current age and planned retirement age.
- Enter your current annual salary and expected raise rate.
- View total lifetime earnings, remaining years, final-year salary and average income.
At age 30, retire 65 (35 years), current HK$360,000 — lifetime earnings by raise rate
| Raise rate | Lifetime earnings | Final-year salary | Average income |
|---|---|---|---|
| 0% | HK$12,600,000 | HK$360,000 | HK$360,000 |
| 2% | HK$17,998,012 | HK$705,843 | HK$514,229 |
| 3% | HK$21,766,349 | HK$983,486 | HK$621,896 |
| 4% | HK$26,514,801 | HK$1,365,954 | HK$757,566 |
| 5% | HK$32,515,311 | HK$1,891,205 | HK$929,009 |
At 30, retire 65 (35 years), HK$360,000. A raise from 3% to 4% adds over HK$4.7m — the compounding of later salaries dwarfs the starting salary's effect. Pre-tax nominal, for reference only.
Case Studies
Mid-career review: 40, HK$600,000, 3% raise
Mr Chan, 40, plans to retire at 65 (25 years left), current salary HK$600,000, average raise 3%. Lifetime ≈ 600,000 × [(1.03)^25 − 1] ÷ 0.03 ≈ HK$21,875,559; average ≈ HK$875,022; final-year ≈ HK$1,219,676.
This HK$21m 'human capital' figure helps him: size life-insurance cover (if the family's breadwinner, cover the lost future income), set a retirement savings target (what fraction to save), and judge whether further study or a job change is worth it (a higher long-run raise or starting salary leverages lifetime earnings hugely). Pair with the retirement-savings calculator.
Starting salary vs raise: the HK$4.7m gap at 3% vs 4%
Same 30, HK$360,000, work to 65 (35 years): at 3% lifetime ≈ HK$21,766,349; at 4% it jumps to ≈ HK$26,514,801 — a gap of about HK$4,748,451.
That ~HK$4.75m difference comes only from one extra percentage point of raise per year. It proves a key point: for lifetime earnings, sustaining a higher raise (via study, promotion, timely moves) compounds far more than the starting salary alone. This is pre-tax nominal; for real purchasing power use the real raise (nominal minus inflation) or the salary-inflation calculator.
FAQ
Why does the raise rate matter so much?
Salary grows by compounding; later-year salaries have a far larger base than the starting salary. Over 30 years, raising the rate from 3% to 4% adds a substantial amount, often more than a one-off higher starting salary — worth striving for a higher long-run raise.
Is this pre-tax or post-tax?
It uses pre-tax annual salary, so the result is pre-tax lifetime earnings. Disposable income needs salaries tax and MPF deducted; use tax and budget tools for that.
Does it account for inflation?
No, the result is nominal. To express it in today's purchasing power, enter the 'real raise rate' (nominal raise minus inflation); the lifetime earnings then read in today's dollars.
How is the lifetime-earnings number actually useful?
Lifetime earnings represent the total value of your future 'human capital'. Once quantified it helps several decisions. (1) Sizing life insurance: if you are the family's breadwinner, that future income is lost on death, so the remaining lifetime earnings (or part of it) is a common benchmark for the needed cover. (2) Setting a retirement savings target: knowing roughly what you will earn, you can work back how much to save/invest to build enough pension. (3) Judging further study or a job change: because the raise rate leverages lifetime earnings hugely, an investment that raises your long-run raise or starting salary (study, qualifications, a better industry) may return far more than its cost. (4) Building a long-term view: seeing the career total helps you allocate income (spend, save, invest, insure) wisely rather than live hand-to-mouth. It is an idealised assumption (fixed raise, no career gap); treat it as a planning frame, not a prediction. Pair with retirement-savings and net-worth calculators.
Why different formulas for zero vs non-zero raise?
Because the two cases are different types of sum. Yearly salaries are S, S(1+g), S(1+g)^2 … S(1+g)^(n-1). If g ≠ 0 they form a geometric series with a closed form: lifetime = S×[(1+g)^n − 1]÷g (the denominator has g, so g cannot be zero). If g = 0 every year is S, so the sum is simply S×n — the limit of the geometric formula as g→0, but the original formula's denominator is zero and must be handled separately to avoid a divide-by-zero. The calculator auto-detects and applies the right one.
