You just got a tech offer letter. The number at the top looks great. Then you start reading the rest of it and realize you have no idea what half of it means.
You are not alone. Offer letters from tech companies are written by legal and compensation teams whose job is to be precise, not clear. The result is a document full of jargon that most engineers read once, feel good about the headline salary, and sign without fully understanding what they agreed to.
This guide translates every component of a standard tech offer letter into plain language, shows you how to calculate your actual total compensation, and flags the specific clauses that trip people up after they have already started the job.
The Four Components of Tech Total Compensation
Every tech offer letter is built from the same four building blocks. Understanding each one separately is the only way to compare offers accurately.
1. Base Salary
Base salary is your fixed annual cash, paid bi-weekly or semi-monthly regardless of how the company performs. It is the most predictable component and the one most people anchor to.
What to watch: Base salary is also the foundation for other calculations. Your 401(k) match, disability insurance, and sometimes your bonus target are all percentages of your base. A lower base with a high bonus target is riskier than a higher base, even if the "Total Compensation" numbers look identical on paper.
2025 ranges by level on Levels.fyi:
- L3 / Entry SWE at FAANG: $120,000 to $155,000 base
- L4 / Mid SWE at FAANG: $155,000 to $195,000 base
- L5 / Senior SWE at FAANG: $195,000 to $245,000 base
- Staff / L6: $240,000 to $300,000+ base
Regional tech hubs like Seattle, New York, and Austin typically run 10 to 20% below San Francisco rates for the same level.
2. Signing Bonus (One-Time, Not Annual)
A signing bonus is a lump sum paid once when you join, sometimes on day one, sometimes after 30 or 90 days. It looks great in the total compensation headline because it inflates Year 1 numbers.
The clawback clause: Almost every signing bonus comes with a repayment requirement. If you leave before 12 months (sometimes 24 months), you owe the money back. Read this clause carefully. Some clawbacks are prorated monthly. Others are all-or-nothing. Some apply only if you voluntarily resign, not if you are laid off.
The Year 2 problem: Signing bonuses do not repeat. If your offer is $200,000 base plus a $50,000 signing bonus, your Year 1 cash is $250,000 but your Year 2 cash drops to $200,000. Factor this into your budget.
Negotiating tip: Signing bonuses are often the easiest component for a recruiter to increase because they are a one-time cost to the company and do not permanently affect their payroll budget. If the base is fixed, ask about the signing bonus first.
3. Annual Bonus (Target vs. Actual)
Most tech companies express annual bonuses as a target percentage of base salary. At large public tech companies, the target typically ranges from 10% to 25% depending on level.
What "target" means: Target bonus is not guaranteed. It is what you receive if you, your team, and the company all hit their performance goals. The actual payout can be anywhere from 0% to 150% or more of target depending on company performance.
How to evaluate it: Ask your recruiter what the actual bonus payout has been for the last two years. If the company missed earnings targets in 2023 and 2024, the bonus pool was likely reduced. Historical data matters more than the target percentage on paper.
Structured vs. discretionary: Some companies have formula-driven bonus calculations tied to specific metrics. Others have fully discretionary bonuses decided by your manager at review time. Discretionary bonuses are harder to predict and easier to reduce.
4. Equity (RSUs): The Component Most People Misread
This is where most engineers leave money on the table, not through negotiation, but through misunderstanding.
RSUs (Restricted Stock Units) are a promise of company shares that become yours over time according to a vesting schedule. They are not stock options. You do not pay to exercise them. When they vest, the shares appear in your brokerage account and are taxed as ordinary income at that moment.
How to read the RSU grant:
Your offer letter will show something like: $400,000 RSU grant over 4 years.
This does not mean you receive $400,000. It means the company is granting you shares worth $400,000 at the current stock price, vesting over four years. The actual dollar value of those shares when they vest depends entirely on the stock price at that future date.
Standard vesting schedules:
Equal quarterly vesting (most common at public FAANG): 25% after year one, then equal quarterly vests for the remaining three years. Simple, predictable, and what most Google, Meta, and Microsoft offers use.
Back-weighted vesting (Amazon's model): Amazon is the most famous example of a back-weighted schedule. Engineers vest 5% in year one, 15% in year two, 40% in year three, and 40% in year four. The offer letter total looks the same as competitors, but the cash flow in years one and two is significantly lower. Amazon compensates for this with higher base salaries and a two-year "signing bonus" paid as $X in year one and $Y in year two to bridge the gap. Read the vesting schedule percentages, not just the headline total.
1-year cliff: Many offers include a one-year cliff, meaning you vest zero shares until your one-year anniversary, at which point a full year's worth vests at once. If you leave or are laid off before that anniversary, you get nothing from the grant.
Refresher grants: Most public tech companies issue additional RSU grants annually as part of performance reviews. These are separate from your initial grant and are how companies keep your total equity value from collapsing as your original grant winds down. Ask your recruiter whether the company has a standard refresher grant program and what the typical size is at your level.
How to Calculate Your Real Annual Total Compensation
Do not use the number on the headline of your offer letter. Use this formula instead.
Year 1 Total Compensation: Base salary + Target bonus + Annual RSU vesting value + Signing bonus
Year 2+ Total Compensation (the number that matters long-term): Base salary + Target bonus + Annual RSU vesting value (no signing bonus)
Example:
| Component | Amount |
|---|---|
| Base Salary | $180,000 |
| Target Bonus (15%) | $27,000 |
| RSU Grant: $300,000 over 4 years | $75,000/year |
| Signing Bonus (Year 1 only) | $30,000 |
| Year 1 TC | $312,000 |
| Year 2+ TC | $282,000 |
The company may advertise this offer as "$312K total comp." The sustainable number is $282,000. Know the difference before you negotiate.
The Hidden Terms That Cost Engineers Money
The "At Will" Clause
Every tech offer letter in the United States (outside Montana) includes "at-will employment," meaning either party can terminate the employment relationship at any time for any lawful reason. This is standard and non-negotiable, but it is important context for everything else in the offer. Your $400,000 RSU grant is worth $0 if you are laid off before any of it vests.
The Non-Compete Agreement
Some offer letters include a non-compete clause restricting where you can work after leaving. Enforceability varies dramatically by state. California does not enforce non-competes. Texas and Florida often do. If you are in a state that enforces them and the clause is broad, you may want an employment attorney to review it before signing.
The Intellectual Property Assignment
Standard in almost all tech offers. You agree that work you do during your employment, and sometimes work related to the company's business done on your own time, belongs to the company. The critical clause to read: does it claim IP created outside of work hours using personal equipment on unrelated projects? Well-written agreements carve this out. Poorly written ones do not.
Bonus Timing and Eligibility
Most offer letters include a line saying you must be actively employed on the date the bonus is paid to receive it. If your bonus is paid in March and you were laid off in February, you typically forfeit it even if you worked the entire bonus year. Ask when annual bonuses are paid, not just what the target is.
Comparing Two Offers Side by Side
Use this framework whenever you have multiple offers to evaluate:
| Company A | Company B | |
|---|---|---|
| Base Salary | $175,000 | $195,000 |
| Target Bonus | $26,250 (15%) | $19,500 (10%) |
| RSU (Year 1 vest) | $62,500 | $30,000 |
| Signing Bonus | $40,000 | $0 |
| Year 1 TC | $303,750 | $244,500 |
| Year 2+ TC | $263,750 | $244,500 |
| Vesting Schedule | 4yr equal quarterly | Back-weighted (5/15/40/40) |
| 401(k) Match | 4% of base | 6% of base |
Company A leads on Year 1 and Year 2 TC. But if Company B has a higher stock price trajectory and stronger refresher grants, the multi-year picture could flip. Model it out over four years, not one.
What to Negotiate and in What Order
Negotiating a tech offer is most effective when you know which components have the most flexibility. Here is the general order from most to least negotiable:
- Signing bonus (easiest, one-time cost to company)
- RSU grant size (often has a 10 to 20% negotiation window)
- Base salary (usually has a 5 to 10% band at the recruiter level)
- Bonus target percentage (almost never moves, tied to the leveling system)
- Vesting schedule (essentially non-negotiable at large companies)
Frequently Asked Questions
What is the difference between RSUs and stock options?
RSUs are grants of actual shares that vest over time. You do not pay to receive them. Stock options give you the right to buy shares at a set price. If the stock price rises above that price, you profit. If it doesn't, the options are worthless. Most public tech companies now issue RSUs. Startups still commonly use options.
How are RSUs taxed?
RSUs are taxed as ordinary income at the time of vesting, based on the fair market value of the shares on the vesting date. Your employer withholds taxes automatically, typically at the 22% federal supplemental rate. You may owe additional taxes if your marginal rate is higher.
What does "target bonus" mean?
Target bonus is what you receive if you and the company hit performance goals. It is not guaranteed. Ask your recruiter about actual payout history over the past two years.
What is a 1-year cliff?
A vesting cliff means you vest zero shares until you complete your first year of employment. At the one-year mark, the full first year's shares vest at once. After the cliff, vesting continues on a regular monthly or quarterly schedule.
Should I accept on the spot?
No. Always ask for 48 to 72 hours to review. Saying "I'm very excited and want to review the full package carefully" is not a red flag to any reasonable recruiter. Accepting without reviewing signals inexperience.
Is the RSU grant based on current stock price?
Yes. If you receive a "$400,000 RSU grant," that typically means the company is granting you shares equal to $400,000 divided by the current stock price. If the stock drops 30% before your shares vest, the actual dollar value when you receive them is significantly lower.
