Why Equity Is the Wealth Engine, Not Salary
A senior tech worker earning $200,000 in base salary will, over 15 years, generate roughly $3M in pre-tax income. A significant amount, but after taxes, housing, family costs, and lifestyle inflation, the actual savings rate is rarely above 20%. That is about $600,000 kept.
The employees who hit $4M are usually not the ones with the highest salaries. They are the ones who accumulated equity in companies that compounded -- and did not sell it prematurely.
RSU Basics: What Vesting Really Means
Restricted Stock Units vest on a schedule, typically 4 years with a 1-year cliff. When shares vest, the IRS treats the vest-day value as ordinary income . Your employer withholds shares automatically to cover the tax. You receive the remaining shares in your brokerage account.
The critical decision comes after vesting: what do you do with the shares you kept?
The most actionable short-term move available to any RSU holder: wait at least 12 months after vesting before selling. On $100,000 in gains this saves roughly $17,000 in federal tax alone. Do this consistently across a career and it adds hundreds of thousands to your final net worth.
The Default Strategy: Sell at LTCG, Diversify Into the S&P 500
After the 12-month hold is complete, the standard playbook is to sell and reinvest into a broad index fund such as VTI, SPY, or FXAIX. This is usually the right call for several reasons:
- Concentration risk: If your employer's stock drops 40% and layoffs follow simultaneously, your portfolio and income take the hit at the same time.
- The S&P 500 baseline: The index has returned approximately 10% per year over the past 30 years with dividends reinvested. Most individual stocks underperform it over a full market cycle.
- Behavioral edge: Selling into an index removes the pressure of timing a single stock. You will not have a bad quarter and panic.
- Tax efficiency: Index funds have very low internal turnover, meaning fewer taxable events year to year.
But there is an important exception that can be worth more than any salary negotiation you will ever do.
The Asymmetrical Bet: 10 Stocks You Should Not Have Sold
Some companies compounded far beyond what any diversification model would have predicted. If you worked at one of these companies and received RSUs, holding your position long-term would have been the highest-ROI decision of your financial life -- by an enormous margin.
The table below shows 10 well-known companies with approximate split-adjusted share prices in 2014 and 2024. All prices are approximate and split-adjusted for stock splits that occurred during the period.

The Math: $10,000 Invested -- Taxes Shown Clearly
The charts below apply a flat 35% tax rate on all gains to give a clean after-tax comparison across assets and time horizons. All charts assume $10,000 invested at the start of the period and sold at the end. [1]
4-Year Horizon (2020 to 2024)
Bars normalized to NVDA ($68,500 after tax). NVDA approximate: $13 split-adj (2020) to $135 (2024). SPY approximate: $320 (2020) to $520 (2024). Cash: average HYSA ~3-4%.
Tax calculation: 35% applied to gains only. Example NVDA: gross $100,000, gain $90,000, tax $31,500, net $68,500.
10-Year Horizon (2014 to 2024)
Bars normalized to NVDA ($232,000 after tax). NVDA gross: $350,000 (35x). Tax: $119,000. Net: $232,000. META gross: $83,000. Tax: $25,550. Net: $57,450. SPY gross: $28,000. Tax: $6,300. Net: $21,700.
20-Year Horizon (2004 to 2024): The Compounding Chasm
At 20 years the disparity becomes too large to render proportionally. A bar chart would make cash and the S&P 500 invisible. The table below shows the actual math instead.
| Asset | Starting $10,000 becomes (gross) | Tax Paid (35% on gains) | After-Tax Value | Net Multiple |
|---|---|---|---|---|
| Cash / HYSA | $14,800 | $1,680 | $13,120 | 1.3x |
| S&P 500 (SPY) | $48,000 | $13,300 | $34,700 | 3.5x |
| Alphabet (GOOGL) | $411,000 | $140,000 | $271,000 | 27x |
| Amazon (AMZN) | $1,057,000 | $366,500 | $690,500 | 69x |
| Netflix (NFLX) | $6,360,000 | $2,226,000 | $4,134,000 | 413x |
Netflix approximate: $1.10/share (2004) to $700 (2024). Amazon split-adjusted $1.75/share (2004, post 20-for-1 split) to $185 (2024). Google IPO August 2004 at $4.25 split-adjusted (post 20-for-1 split) to $175 (2024). S&P 500 approximate: $110 (2004) to $520 (2024) including reinvested dividends estimate.
When to Hold -- and When Not To
Default: Sell at LTCG, Move Into Index
- Wait at least 12 months after each vesting tranche to qualify for long-term capital gains rates.
- Sell the position and recognize the gain at the lower LTCG rate (20% federal for high earners).
- Reinvest proceeds into a broad index fund (VTI, FXAIX, or SPY) to remove single-stock concentration risk.
- Repeat on each vesting tranche as a systematic rule, not a one-time decision.
Exception: The High-Conviction Long Hold
There are situations where holding individual stock beyond the standard diversification window is a reasoned bet, not a mistake. Ask yourself all four questions:
- Does the company have durable competitive advantages visible in its revenue growth, margins, and market position?
- Is the category growing faster than the overall economy with the company taking share?
- Are you already diversified enough (through index holdings, 401k, real estate) that a 50% drawdown in this position would not change your lifestyle or force you to sell?
- Do you understand the business well enough to hold through painful drawdowns without panic-selling?
If all four answers are yes, holding a concentrated position long-term is a legitimate strategy. If any are no, sell and diversify.
Why You Should Not Job-Hop Too Much
Every time you leave a company, you reset your vesting clock. A standard 4-year schedule means your first 12 months are unvested (the cliff). If you leave after 2 years, you walked away from 2 years of equity. Over a 15-year career with three unnecessary job changes, you may have forfeited $300,000 to $500,000 in unvested grants -- equity that would have compounded for a decade.
Beyond the vesting math, staying longer gives you the institutional knowledge to evaluate whether the equity is worth holding. You cannot make a confident 10-year bet on a company you have known for 18 months.
- Understand the full 4-year vesting schedule before you accept any offer.
- Model the unvested equity cost before you accept a competing offer -- recruiters often do not include this in their pitch to you.
- If you do move, negotiate for a signing bonus that covers unvested equity forfeited at your previous employer.
- Give yourself at least one full vesting cycle before deciding whether the company's equity is worth a long-term bet.
The $4M Path: How the Math Stacks Up
A realistic model for a senior tech worker with $150,000 in annual RSU grants and a long-term capital gains strategy over 15 years:
| Wealth Source | Annual Contribution | 15-Year Estimate | Notes |
|---|---|---|---|
| 401k + direct savings from salary | $40,000 / yr | ~$600,000 | Max 401k ($23,000) plus $17,000 taxable savings |
| RSUs diversified into S&P 500 (after LTCG) | $80,000 / yr (after tax) | ~$1,200,000 | $150k grants, hold 12+ months, 20% LTCG, reinvest in index |
| Compounding on all holdings at 7% annual | Grows with balance | ~$1,500,000 | Compound growth on cumulative invested assets |
| 1 or 2 asymmetrical equity holds (10+ year bet) | Varies | ~$700,000 | Conservative estimate -- no lottery required, just high-quality companies |
Total: approximately $4,000,000. No crypto moonshot. No startup IPO windfall required. Just a consistent, tax-efficient equity strategy applied for 15 years at a company that pays competitively in RSUs.
Practical Checklist
- Hold each vested RSU tranche for at least 12 months to qualify for long-term capital gains rates before selling.
- Track each vesting date and the 12-month hold expiry in a calendar or spreadsheet -- do not rely on memory.
- After the hold period, sell and reinvest into a broad index unless you have a documented, high-conviction case for holding.
- Before each job change, calculate the unvested equity you will forfeit and require that it be compensated in your new offer.
- Once a year, review your equity concentration. If any single stock represents more than 20% of your net worth, consider trimming after the 12-month hold.
- Work with a CPA who understands equity compensation -- not a general tax preparer.
- Store your vesting schedule, grant agreements, and tax basis documents in one accessible location for each grant year.

Final Take
RSUs are not a bonus. They are equity ownership in the company you help build. The employees who ended up financially free were not necessarily the highest earners. They were the ones who held the right companies long enough, paid the right taxes at the right time, and did not let impatience, fear, or lifestyle inflation get in the way.
The $4M number is not magical. It is the output of getting these decisions right, consistently, for a decade or longer. The math is on your side. Do not get in its way.
