Silicon Valley SWE Equity (Compensation Guide)
Silicon Valley software engineers may receive stock options, restricted stock, or RSUs, but a grant’s headline value is not cash. To judge an offer, identify the award type, share count, vesting, strike price, ownership context, tax events, and path to a sale. Compare equity separately from salary, then model cautious outcomes before negotiating or making tax decisions.
Equity can make an offer look much larger, while the details that determine its value sit in several documents. If you are comparing jobs between coding interviews, coursework, or a move, focus on what you can verify: what you receive, when it vests, what it may cost, and whether you can sell it.
I use one practical rule when reviewing an offer: treat salary as cash compensation and equity as a separate, uncertain asset. This guide explains how to assess both public-company and startup awards, what to ask before accepting, and which dates matter later. It is educational, not personal tax or legal advice.
Understand the equity in your offer
Equity compensation gives you a right to shares or a stake in a company, subject to the award’s rules. The label alone does not tell you its cash value. Start with the grant agreement, then check how many shares it covers, when they vest, what you must pay, and when taxes may apply.
Stock options, restricted stock, and RSUs
Stock options give you the right to buy shares at a set price, called the strike or exercise price. Incentive stock options (ISOs) and nonqualified stock options (NSOs) have different tax rules. Restricted stock is actual stock subject to conditions. Restricted stock units (RSUs) are a promise to deliver shares or cash when conditions are met.
For options, the number of options is not the number of shares you own. You usually must exercise, or buy, vested options before they become shares. The spread is the share’s fair market value at exercise minus the strike price. A larger spread may mean more cost and tax exposure.
For typical U.S. employee RSUs, the value of shares delivered at vesting is generally treated as wage income. Private-company RSUs may settle later, depending on the plan. Restricted stock differs from an RSU because shares are transferred earlier, subject to restrictions. A tax professional can explain whether an 83(b) election applies and its deadline.
Vesting and ownership
Vesting is the process by which you earn the award over time. A common schedule has four years of vesting and a one-year cliff, but schedules vary. A cliff means no portion vests before a set date; after that, the grant may vest in steps. Read the actual schedule, not a recruiter’s shorthand.
Ask for the grant’s share count and the company’s fully diluted share count. The latter estimates all shares if options and other convertible awards were exercised or converted. Divide your grant by that total for an approximate ownership percentage. Ask for the date and assumptions behind the denominator; a percentage is not a fixed promise because later financing can dilute ownership.
Compare equity offers using realistic numbers
A useful comparison separates cash pay from uncertain equity and states every assumption. Public-company shares may be easier to value because they trade in a market, but prices change and trading rules apply. Private-company shares may have no available buyer. Neither a quoted value nor an internal estimate guarantees what you can receive.
| Example offer | What to verify | Cautious way to assess it |
|---|---|---|
| Public-company RSUs | Number of units, vest dates, share price used in the offer, tax withholding, trading rules | Treat the quoted value as a snapshot, not a fixed payout. Recheck the share price and vesting dates. |
| Startup options | Option count, strike price, fully diluted share count, expiration, exercise deadline, sale limits | Estimate ownership and exercise cost. Do not count the grant as cash before a sale is possible. |
| Restricted stock | Shares transferred, restrictions, purchase price, tax deadlines, sale limits | Confirm when ownership and tax events occur; get advice before an election or payment. |
Illustrative startup calculation: Suppose an offer grants 20,000 options, the strike price is $2, and fully diluted shares total 20 million. The grant represents about 0.1% at that point in time. Exercising all options would cost $40,000. If a future sale price for common shares were $10 each, the simple pre-tax spread would be $160,000. That is only a scenario: dilution, taxes, company terms, and the possibility of no sale can change the result.
Illustrative public-company calculation: Suppose an offer grants 1,000 RSUs and uses a share price of $100 to describe a $100,000 grant. If all units vest over four years, that does not mean you receive $25,000 in cash each year. The share price may rise or fall, withholding may apply, and the units vest only on the stated dates.
These examples are not market benchmarks or predictions. When I compare offers, I put base pay, bonus, and equity in separate columns. For a private grant, I build downside, base, and upside cases, and do not treat the upside as spendable income.
Check taxes, liquidity, and private-company terms
A tax event is a point when an award may create tax due, even if you have not sold shares. Liquidity is your ability to turn shares into cash. For private-company equity, tax timing and liquidity can fall far apart, so confirm both before exercising or accepting a grant’s stated value.
What can trigger tax?
- ISOs: Exercise may create an alternative minimum tax (AMT) adjustment based on the difference between fair market value and strike price. A sale before the required holding periods may be a disqualifying disposition. For potential qualifying-disposition treatment, the general tests are holding at least two years from grant and one year from exercise. Individual results depend on the facts and current tax rules.
- NSOs: Exercise generally creates ordinary compensation income on the difference between fair market value and strike price. A later sale may create capital gain or loss. Ask how the employer will report income and withholding.
- RSUs: For typical U.S. employee RSUs, the value delivered at vest is generally wage income. Later price movement is generally a separate capital gain or loss when you sell. Private-company settlement terms may affect timing.
A tax bill can arise before you can sell shares, especially with private-company options or stock. Before exercising, estimate the exercise payment and possible taxes, and ask a qualified tax professional to review your award and personal situation. Do not rely on a generic online calculator as a final answer.
What private-company documents matter?
Ask for the equity plan and grant agreement, plus available information on the latest valuation and share count. A 409A valuation is used for certain private-company tax and option-pricing purposes; it is not a promise of sale price. The latest preferred-stock price may also differ from the value of common shares employees receive. Preferred shares can have rights that affect proceeds in a sale.
SEC Rule 701 permits certain eligible private companies to offer compensatory securities under an exemption. It does not guarantee a market, make resale unrestricted, or ensure a future payout. Review:
- Exercise price and expiration date
- Vesting schedule and any acceleration terms
- Post-termination exercise deadline
- Company repurchase, transfer, and sale restrictions
- Tender-offer rules and any lockup after a public listing
- How the company handles withholding and settlement
Record the answers and the date you received them. Equity terms are governed by the documents, not by a verbal estimate of what the grant “should be worth.”
Illustrative cases: applying the numbers
These examples are hypothetical, not reports of specific employees or companies. They show how award details can change a decision. Use your own grant terms and tax advice for a real offer, exercise, or sale.
Case 1: Startup offer with options. A software engineer is offered 20,000 options and learns that the strike price is $2. The recruiter’s estimate uses a recent preferred-stock price, but the engineer asks for the fully diluted share count, option expiration, and exercise window. At 20 million fully diluted shares, the grant is about 0.1% before future dilution. The engineer also sees the $40,000 exercise cost and decides not to count the estimated grant value as salary.
Case 2: Public-company offer with RSUs. Another engineer receives 1,000 RSUs valued at $100 per share when the offer is made. Instead of assuming $100,000 is guaranteed, they check the vest dates, trading rules, and tax withholding. They compare the salary they can rely on with the value of shares that may change before each vest date.
Case 3: Leaving a private company. An employee with vested options plans to resign. Before setting a departure date, they check the grant agreement for the post-termination exercise deadline, then ask about exercise cost, expiration, sale restrictions, and tax exposure. A short deadline can force a costly choice, so confirming it before leaving is more useful than relying on a general rule.
A practical roadmap for reviewing and managing equity
A roadmap turns a complex grant into a set of decisions and dates. Before accepting, gather the documents and test the assumptions. After joining, track vesting and tax events. Before leaving or selling, confirm deadlines and restrictions. Keep records so you can explain each transaction to a tax professional.
- Prepare: Collect your offer letter, equity plan, grant agreement, and any valuation or capitalization details the company can share. Identify award type, share count, strike price, vesting, expiration, and liquidity limits.
- Evaluate: Compare salary and bonus separately from equity. For options, calculate the exercise cost. For all private grants, ask for ownership context and model a downside case, including no liquidity event.
- Negotiate: Ask clear questions about grant size, the fully diluted share count, strike price, vesting, exercise window, and sale rules. If the company will not provide a requested figure, note the uncertainty rather than filling the gap with an assumption.
- Manage: Track vest dates, exercise deadlines, tax payments, trading windows, and company sale events. Keep copies of grant, exercise, payroll, and transaction records.
- Transition: Before a job change, confirm the exact post-termination deadline and any exercise or settlement steps in writing. Before exercising or selling, get personal tax guidance, especially for ISOs, possible AMT, or a large share position.
The main takeaway is simple: an equity offer is a set of rights and risks, not a cash number. You can make a better decision by confirming the award terms, testing more than one outcome, and marking the next deadline on your calendar.
Frequently asked questions
These short answers cover common questions about software-engineer equity offers. They are starting points, not substitutes for the grant documents or personal tax advice. The exact result depends on the award type, company terms, timing, and applicable tax rules.
Is startup equity guaranteed compensation?
No. A private-company grant may never become sellable or valuable. Treat salary as cash and evaluate equity separately.
How do I calculate my ownership percentage?
Divide your share or option count by the company’s fully diluted share count, using the same date and share basis. Later financing may dilute the percentage.
Are options the same as shares?
No. Options usually give you the right to buy shares at a set strike price. You generally need to exercise vested options to own the shares.
What is the difference between an ISO and an NSO?
They are two types of stock options with different tax rules. ISOs may involve AMT at exercise and holding-period tests; NSO exercise generally creates compensation income on the spread.
When are RSUs usually taxed?
For typical U.S. employee RSUs, the value delivered at vest is generally treated as wage income. Confirm the plan’s settlement terms, especially for private-company RSUs.
Does a 409A valuation tell me what my shares are worth?
It is not a guaranteed sale price. It is used for certain private-company tax and option-pricing purposes and may differ from preferred-stock pricing or future proceeds.
Does SEC Rule 701 mean I can sell my private shares?
No. The rule provides an exemption for certain compensatory offerings by eligible private companies. It does not guarantee liquidity or unrestricted resale.
What happens to my options when I leave?
The grant documents set the post-termination exercise deadline and other terms. Confirm the exact date and cost before leaving; do not assume a standard window applies.
What records should I keep?
Keep your offer, equity plan, grant agreement, vesting records, exercise confirmations, tax forms, and sale records. They help you track terms and support tax reporting.
Should I exercise options as soon as they vest?
Not automatically. Exercise cost, taxes, expiration, liquidity, and your personal finances all matter. Ask a qualified tax professional to review your situation before deciding.
