Every tech compensation discussion eventually arrives at the same question: should you optimize for higher base salary or more equity? The answer depends on the type of equity, the company's stage, your tax situation, and your risk tolerance. Most advice online oversimplifies this. We will not.

Here is a complete breakdown of stock options versus base salary, with real math, real tax implications, and a decision framework you can actually use.

The Three Types of Equity You Will Encounter

Incentive Stock Options (ISOs)

ISOs give you the right to buy company shares at a predetermined price (the strike price). You do not own anything until you exercise—meaning you pay the strike price to purchase the shares.

Key characteristics:

  • Granted primarily by startups and pre-IPO companies
  • Strike price is set at fair market value (FMV) on the grant date
  • Typical vesting: 4 years with a 1-year cliff
  • Must exercise within 90 days of leaving the company (at most employers)
  • Favorable tax treatment if you meet holding requirements

The value proposition: If the company's share price rises from your $2 strike price to $20, each option is worth $18 in profit. On 10,000 options, that is $180,000 in paper gains.

The risk: If the company fails or the share price stays flat, your options are worth zero. You have spent four years vesting something with no value—and if you exercised early, you have lost real cash.

Restricted Stock Units (RSUs)

RSUs are a promise to give you actual shares on a future date, provided you remain employed. Unlike options, there is no strike price—you receive shares outright as they vest.

Key characteristics:

  • Standard at public companies and late-stage startups
  • No purchase required—shares are granted to you
  • Value = share price × number of shares vesting
  • Taxed as ordinary income on the vesting date
  • Typical vesting: 4 years (schedule varies by company)

The value proposition: RSUs always have value as long as the company's stock price is above zero. At a public company, this is essentially guaranteed compensation—closer to a cash bonus than a lottery ticket.

Non-Qualified Stock Options (NSOs/NQSOs)

NSOs work like ISOs but with worse tax treatment. They are more common for contractors, advisors, and in some international grant structures. The spread (difference between strike price and current price) is taxed as ordinary income upon exercise, with no special capital gains treatment.

For this analysis, we will focus on ISOs (startup equity) and RSUs (public company equity), as these are the two types most tech workers encounter in job offers.

FAANG RSU Vesting Schedules: Not All Equal

One of the most consequential—and least understood—differences between Big Tech offers is the vesting schedule. The same $400,000 in RSUs can be worth dramatically different amounts in year one depending on the employer.

| Company | 4-Year Vesting Schedule | Year 1 Value (on $400K grant) | |---------|------------------------|-------------------------------| | Google | 25% / 25% / 25% / 25% (equal) | $100,000 | | Meta | 25% / 25% / 25% / 25% (equal) | $100,000 | | Amazon | 5% / 15% / 40% / 40% (backloaded) | $20,000 | | Apple | 25% / 25% / 25% / 25% (equal, quarterly) | $100,000 |

Amazon's backloaded schedule is the most aggressive. To compensate, Amazon offers larger year 1–2 cash signing bonuses to bridge the gap. A typical Amazon L5 offer might include a $120K signing bonus ($80K year 1, $40K year 2) specifically because only 20% of RSUs vest in years 1–2.

Why this matters for your decision: If you are comparing a $200K base + $400K RSU offer from Amazon against a $185K base + $300K RSU offer from Google, the Google offer may actually pay more in years 1–2 despite the lower headline number.

The Real Math: Startup Equity vs. More Base Salary

Here is the scenario most engineers face: a startup offers $140K base + 0.1% equity, while an established company offers $190K base + standard RSUs. Which is worth more?

Scenario A: The Startup (0.1% equity)

Assumptions:

  • Current company valuation: $100 million (Series B)
  • Your 0.1% = $100,000 in current paper value
  • 4-year vesting with 1-year cliff
  • Strike price: $2/share (10,000 options at FMV)

If the company reaches $1 billion (10x):

  • Your 0.1% is worth $1,000,000
  • Minus dilution (assume 30% over 4 years): ~$700,000
  • Minus strike price paid: $20,000
  • Minus taxes (see below): varies, but ~$150K–$250K
  • Net payout: $430,000–$530,000
  • Annualized over 4 years: $107,500–$132,500/year in equity value
  • Plus $140K base = $247,500–$272,500 total annual comp

If the company reaches $500 million (5x):

  • Post-dilution value: ~$350,000
  • After taxes: ~$210,000–$260,000
  • Annualized: $52,500–$65,000/year
  • Plus base = $192,500–$205,000 total annual comp

If the company stays flat or fails (most likely scenario):

  • Your equity is worth $0–$70,000 (pre-tax)
  • You earned $140K/year for 4 years. That's it.

Scenario B: The Established Company ($190K base + RSUs)

Assumptions:

  • $190K base salary
  • $200K RSU grant over 4 years ($50K/year vesting)
  • Stock grows 8% annually (S&P average)

Year-by-year:

  • Year 1: $190K + $50K RSU = $240,000
  • Year 2: $190K + $54K RSU (8% growth) = $244,000
  • Year 3: $190K + $58K RSU = $248,000
  • Year 4: $190K + $63K RSU = $253,000
  • Average: $246,250/year

The comparison:

| Outcome | Startup Total (4yr) | Established Total (4yr) | |---------|---------------------|------------------------| | Startup hits $1B (10x) | $990K–$1.09M | $985K | | Startup hits $500M (5x) | $770K–$820K | $985K | | Startup stays flat/fails | $560K–$630K | $985K |

The established company wins in two out of three scenarios. The startup only wins if it achieves a 10x outcome—which historically, roughly 10–15% of Series B companies accomplish.

The Tax Trap Nobody Warns You About

The ISO AMT Problem

When you exercise ISOs, the spread (current FMV minus strike price) is not taxed as regular income. Sounds great. But it is counted as income for Alternative Minimum Tax (AMT) purposes.

Example:

  • You exercise 10,000 ISOs at $2 strike price
  • Current FMV is $20/share
  • Spread: $18 × 10,000 = $180,000
  • AMT rate: ~26–28% on the spread
  • AMT bill: $46,800–$50,400
  • You owe this in the year of exercise—even if you cannot sell the shares

This is the classic "paper millionaire, cash poor" trap. During the 2000 dot-com bust, engineers owed six-figure AMT bills on shares that had become worthless. The IRS does not care that your shares lost value after you exercised.

How to mitigate:

  • Exercise early when the spread is small (83(b) election within 30 days of grant)
  • Exercise in a year when your other income is lower
  • Spread exercises across multiple tax years
  • Consult a tax advisor before exercising anything over $50K in spread

RSU Taxation: Simpler but Painful

RSUs are taxed as ordinary income on the vesting date. There is no special treatment—it is the same as your salary.

Example:

  • 1,000 shares vest when stock price is $150
  • Taxable income: $150,000
  • At a 35% marginal rate: $52,500 in additional tax
  • Most companies auto-sell a portion of vesting shares to cover withholding ("sell to cover")

The LTCG opportunity: If you hold RSU shares for 12+ months after vesting, any additional gains are taxed at long-term capital gains rates (15–20%) instead of ordinary income rates (up to 37%). This creates a meaningful tax advantage for shares you believe will continue appreciating.

When Equity Beats Cash: The Realistic Scenarios

Equity outperforms higher base salary when:

  1. You join a late-stage company pre-IPO (Series C/D+) with clear path to liquidity. The valuation multiple may only be 2–3x, but the probability of a positive outcome is 40–60%, not 10%.

  2. You are at a FAANG and the stock appreciates significantly. Engineers who joined Google, Apple, or Nvidia in 2020–2022 saw their RSU grants double or triple in value. A $300K RSU grant became $600K–$900K in realized income.

  3. You receive refresher grants. Most large tech companies grant additional RSUs annually on top of your original grant. At Google, annual refreshers can be $50K–$150K+ for senior engineers, compounding your equity exposure.

  4. Your marginal tax rate is already high. Additional base salary at the 37% federal bracket yields $0.63 per dollar. RSUs held for 12+ months and sold at LTCG rates yield $0.80–$0.85 per dollar on the gains above vesting price. The tax-advantaged upside of equity becomes more valuable as your income rises.

When Cash Beats Equity: The Honest Truth

More base salary is the better choice when:

  1. The company is early-stage (Seed/Series A). Roughly 75% of venture-backed startups fail to return investor capital. Your 0.05–0.2% equity stake has an expected value far below $50K in most cases.

  2. You have high fixed costs. Mortgage payments, student loans, childcare, or family obligations require reliable cash flow. Equity is illiquid and uncertain—it cannot pay your rent.

  3. You are not prepared to hold for 5–7+ years. Startup equity has no liquidity until an exit event (IPO or acquisition). Even RSUs require you to stay employed to vest. If you tend to switch jobs every 2–3 years, you are leaving unvested equity on the table.

  4. The equity offer is small. At many mid-stage startups, engineering hires receive 0.01–0.05% equity. On a $200M company, that is $20K–$100K pre-tax, pre-dilution over four years. Compare that to a $50K base salary increase, which gives you $200K more in cash over the same period—guaranteed, taxed at known rates, and available immediately.

The Decision Framework

Use this flowchart to guide your equity-vs-cash decision:

Step 1: What stage is the company?

  • Public company → RSUs are near-cash. Evaluate based on stock growth outlook.
  • Late-stage private (Series C+) → Moderate risk, moderate reward. Worth taking if the equity percentage is meaningful (>0.05%).
  • Early-stage (Seed–Series B) → High risk. Only take significant equity if you genuinely believe in the team and market, and can afford to earn below market base for 4 years.

Step 2: What are your cash needs?

  • High fixed costs or major near-term purchases (home, wedding, etc.) → Prioritize base salary.
  • Low burn rate, strong emergency fund, no major upcoming expenses → You can afford more equity exposure.

Step 3: What is your tax bracket?

  • Below $191,950 (24% bracket) → Extra base salary is taxed relatively favorably. Equity has less tax advantage.
  • Above $243,725 (35%+ bracket) → The LTCG advantage on held RSUs is significant. Equity becomes more tax-efficient for wealth building.

Step 4: What is the equity percentage and valuation?

  • Calculate the expected value: equity % × current valuation × realistic multiple (2x for late-stage, 5x optimistic for early-stage) × (1 - 30% dilution) × (1 - marginal tax rate)
  • Compare to the cash alternative: salary difference × 4 years × (1 - marginal tax rate)
  • If equity expected value > 1.5x the cash alternative, the risk-adjusted return favors equity

The Comparison Table

| Factor | Higher Base Salary | Stock Options/RSUs | |--------|-------------------|-------------------| | Certainty | Guaranteed | Variable (0 to 10x+) | | Liquidity | Immediate (every paycheck) | Delayed (vesting + holding) | | Tax treatment | Ordinary income | ISO: potential LTCG; RSU: ordinary + LTCG on gains | | Downside risk | None (it's your salary) | Total loss possible (startup options) | | Upside potential | Limited to raises | Theoretically unlimited | | Impact on 401(k)/benefits | Often increases match | Usually no impact | | Mortgage qualification | Lenders count 100% | Lenders discount heavily | | Job mobility | No forfeiture risk | Unvested equity lost on departure |

What the Data Says

According to compensation data across our salary insights directory, the median software engineer's total compensation breaks down roughly as follows at major tech companies:

  • Base salary: 50–65% of total comp
  • RSUs/equity: 20–35% of total comp
  • Bonus/other: 10–15% of total comp

At the staff/principal engineer level, equity often exceeds base salary—sometimes by 2x or more. This is by design: companies want senior talent to have significant skin in the game, and the tax advantages of equity scale with income.

For engineers at the highest-paying tech cities, equity can represent $100K–$300K+ in annual vesting value, making it the single largest component of compensation.

The Bottom Line

For most tech workers at most companies, higher base salary is the safer and often smarter choice. The guaranteed, liquid, immediately useful nature of cash makes it the right default—especially for engineers earlier in their careers who are building financial foundations.

Equity becomes the better play under specific conditions: public company RSUs at a business you believe will grow, late-stage pre-IPO with clear exit timeline, or when your financial position allows you to absorb the risk of illiquid, uncertain compensation.

The worst decision is accepting below-market base salary for a tiny equity stake at an unproven startup—the expected value math almost never works in your favor. If a startup cannot offer meaningful equity (0.1%+ for early engineers, 0.5%+ for first 10 hires), the premium base salary at an established company will almost certainly generate more lifetime wealth.
