Total Compensation Explained: Base, Bonus, RSUs, Sign-On

You get an offer letter that says "total compensation: $420,000 per year." You feel rich. Then you realize half of that is stock you cannot sell for years, the bonus is "target" (not guaranteed), and the sign-on has tax implications you did not expect.

Total compensation in US tech is genuinely confusing. Here is exactly how each piece works, with real math.

The Four Main Components#

Every modern US tech offer has these pieces:

1. Base salary
2. Annual bonus
3. RSU (Restricted Stock Units) or stock options
4. Sign-on bonus

There are also benefits, but those typically do not get aggregated into "total comp" numbers.

Let me break each one down with examples from actual offer letters in 2026.

Base Salary#

Base is the most straightforward part. It is the cash you receive every two weeks (bi-weekly) or every month, before bonuses and stock.

How It Works

Base is paid in dollars. It is subject to income tax, Social Security, Medicare, and any state and local taxes.

If your base is $200,000, you receive $7,692 per bi-weekly paycheck before taxes. After typical California taxes (federal 32% + state 9.3% + FICA 7.65%), you take home roughly $4,400 per check, or $114,400 per year.

When You Get Paid

Most US tech companies pay bi-weekly (every 2 weeks, 26 paychecks per year). Some pay semi-monthly (15th and 30th, 24 paychecks per year). The total annual is the same.

How Base Adjusts

Most companies do annual base reviews. Cost-of-living adjustments are typically 2 to 5 percent annually. Promotion-driven base bumps can be 10 to 30 percent. Job-hopping base bumps are often 20 to 50 percent.

Why Base Matters

Base is the only number you can fully count on. Bonus targets can be missed. RSU value can crater if stock drops. Sign-on is one-time. Base shows up reliably every paycheck.

When negotiating, prioritize base if you value stability. Prioritize RSU if you value upside and have other income sources.

Annual Bonus#

The annual bonus is a percentage of your base that you receive (typically) once per year based on performance.

How It Works

Your offer letter will say something like:

"Target annual bonus: 15 percent of base salary, paid annually based on individual and company performance."

If your base is $200k and target bonus is 15 percent, your target bonus is $30k. But "target" is the key word.

Why Target Matters

Bonuses are usually paid based on a multiplier of target. Examples:

• Company performance multiplier: 0.5x to 1.5x based on company hitting financial goals
• Individual performance multiplier: 0.5x to 1.5x based on your performance rating

A bonus of "15 percent target" can pay anywhere from 7.5 percent of base (bad year, low rating) to 25 percent of base (great year, top rating).

Average Bonus Outcomes

For a typical software engineer at a healthy US tech company:

• 40 percent of years: hit target exactly (100% multiplier)
• 30 percent of years: above target (110-130% multiplier)
• 20 percent of years: below target (70-90% multiplier)
• 10 percent of years: significantly off (50-70% multiplier or worse)

Plan financially based on 90 percent of your target bonus, not 100 percent.

When Bonuses Are Paid

Most companies pay annual bonuses in Q1 of the following year (January to March). Some pay quarterly. Some pay semi-annually.

If you leave the company before the bonus payout date, you typically forfeit the bonus. This is a common retention lever.

RSU (Restricted Stock Units)#

This is where it gets complex. RSUs are the biggest part of FAANG-level total comp, often more than base.

How They Work

When you get an RSU grant of, say, $400,000 over 4 years, it means:

1. The company sets aside shares worth $400k at signing date
2. Those shares vest (become yours) over 4 years on a schedule
3. When shares vest, they are taxed as ordinary income
4. After vesting, you can sell them anytime (subject to trading windows)

The Vesting Schedule

The standard schedule at most US tech companies in 2026:

• 25% after 1 year (cliff)
• Then monthly or quarterly vesting for the next 3 years

Some companies use front-loaded vesting:

• Meta: 25% / 25% / 25% / 25% (even quarterly)
• Amazon: 5% / 15% / 40% / 40% (heavily back-loaded)
• Google: 25% / 25% / 25% / 25% (monthly after cliff)
• Apple: similar to Google

Amazon's back-loaded schedule is a retention play. You only get 20 percent of your stock in the first two years, then 80 percent in years three and four. Many engineers leave Amazon at the 2-year mark when their pay drops because RSU is gone.

The Tax Trap

When RSU vests, the IRS counts the value as ordinary income on that vesting date. You owe taxes based on the share price at vesting, regardless of whether you sell.

Example: 100 shares vest when stock is at $300. That is $30,000 of taxable income. You owe federal + state + FICA taxes on that $30,000 (typically 40-50% combined). If you do not sell shares to cover the tax, you owe $12,000 to $15,000 out of pocket.

Most companies offer "sell to cover" by default. They automatically sell enough shares to cover your tax liability when shares vest.

Stock Price Risk

The number on your offer letter assumes the stock price stays the same. It does not.

Example: You get an RSU grant of 1,000 shares at $100/share = $100,000 stated value.

• If stock doubles to $200, your grant becomes $200,000
• If stock drops to $50, your grant becomes $50,000

This is why FAANG offers with rising stock prices feel like winning the lottery, and offers from declining stocks feel like a slow loss.

Refresher Grants

After your initial 4-year grant vests, do you get more stock? Companies vary:

• Meta, Google, Apple: annual refresher grants based on performance (usually $100k to $400k+ per year for senior ICs)
• Amazon: smaller, less predictable refreshers
• Most startups: no automatic refreshers, but discretionary grants exist

If your refresher is strong, your effective compensation stays high. If it is not, your "cliff" hits and your comp drops significantly at year 4.

Stock Options (Less Common)#

Some companies, especially earlier-stage startups, give stock options instead of RSUs.

How They Work

You receive the right to buy a certain number of shares at a fixed price (the "strike price"). When the company is private or pre-IPO, this is theoretical value.

Options have value if the stock price exceeds the strike price. They are worth $0 if the company fails.

Why They Are Different from RSUs

• RSUs: guaranteed value, you pay tax when shares vest
• Options: variable value, you pay tax when you exercise (and possibly sell)

Options require careful tax planning. Misunderstanding them can lead to significant tax bills you cannot pay.

Where Options Show Up

• Early-stage startups (pre-Series C): always options
• Mid-stage startups (Series C to pre-IPO): often options, sometimes RSUs
• Public companies: almost always RSUs

If you have options, talk to a tax advisor before exercising. The mistakes here can be expensive.

Sign-On Bonus#

A one-time cash bonus paid when you start (or shortly after).

How It Works

Your offer might say:

"Sign-on bonus: $75,000, paid in two installments. $50,000 within 30 days of start date. $25,000 after 12 months of continued employment."

This is "two-tranche" structure, common at FAANG companies. The first chunk is paid quickly, the second is conditional on staying.

The Clawback Clause

Almost all sign-on bonuses have a clawback. If you leave the company within 12 to 24 months, you must repay some or all of the sign-on.

Read the clawback terms carefully:

• Some prorate (pay back $30k of $75k if you leave at month 6)
• Some are all-or-nothing (pay back full $75k if you leave at month 11)
• Some have specific carve-outs (no clawback if laid off)

If you have any doubt about staying long-term, factor this in.

Why Sign-On Bonuses Exist

Sign-on bonuses exist primarily to make candidates whole for compensation they lose by changing companies. If you have $80k of unvested RSU at your current company, a $75k sign-on offsets that loss.

They also help companies offer better total comp without permanently raising base or RSU.

Tax Treatment

Sign-on is taxed as ordinary income. In a high-bracket year, you might lose 40-50 percent to taxes. A $75k sign-on becomes $38k-$45k in your bank account.

How "Total Comp" Is Calculated#

When someone says "I got a $400k offer," here is what they usually mean:

Total Comp = Base + (Bonus Target) + (Annual RSU Vesting Value)

Note: this excludes sign-on (since sign-on is one-time) and assumes RSU vests evenly over 4 years.

Example:

• Base: $200,000
• Bonus target: $30,000
• RSU grant: $800,000 over 4 years = $200,000/year average

Total Comp = $200k + $30k + $200k = $430k

But this is an approximation. Reality:

• Year 1 (with sign-on of $75k, RSU 25% cliff): $200k + $30k + $200k + $75k = $505k
• Year 2: $200k + $30k + $200k = $430k
• Year 3 (raise, refresher, hopefully): $215k + $35k + $250k = $500k
• Year 4: $225k + $40k + $300k = $565k (with refreshers)

After year 4, if no refreshers were given, you face a "cliff" where comp drops to roughly base + bonus.

What Actually Matters for Your Decision#

When evaluating an offer, look at:

1. First-year cash: base + bonus + sign-on. The money you actually receive in year 1.
2. Steady-state comp: base + bonus + annualized RSU + refresher. Year 3 or 4 comp.
3. Stock outlook: is the company stock likely to grow or decline?
4. Bonus reliability: how often do bonuses hit target at this company?
5. Refresher policy: explicit and predictable, or vague and discretionary?

A higher "total comp" offer with poor refresher policy can pay less over 5 years than a lower offer with strong refreshers.

Negotiating Each Component#

Different components have different negotiation flexibility:

• Base: easiest 5-15% upside
• Sign-on: easiest large upside (can often add $25-100k)
• RSU: highly negotiable at FAANG, can move 20-50%
• Bonus target: hard to move

For details on the negotiation playbook, read how to negotiate salary in a US tech interview.

Tax Planning Considerations#

US tech compensation in high-cost states triggers serious tax bills.

• California: top combined federal + state rate can hit 50%+
• New York: similar to California
• Washington, Texas, Florida: no state income tax (significant savings)

For a $400k total comp engineer:

• In California, take-home after all taxes is roughly $230k
• In Washington, take-home is roughly $260k

The same comp number means very different things in different states.

What to Do This Week#

If you are evaluating offers:

1. Make a spreadsheet of all 4 components for each offer
2. Calculate year 1, year 2, year 3, and year 4 cash flows
3. Adjust for state taxes if location differs
4. Identify components you can negotiate
5. Get competing offers if possible

Then negotiate. Use our salary negotiation guide and the career planning tools to maximize what you get.
