A senior engineer came to me with two offers. Company A: $195K base. Company B: $175K base. "A pays more," she said, "so I'm going with A."

She was about to leave $150,000 on the table.

Company B had RSUs worth $120K annually at current price. Company A had options that might be worth something someday. When we calculated total compensation properly, B paid $295K versus A's $215K. The "lower" offer was $80K better.

This happens constantly. Engineers focus on the number they understand—base salary—while ignoring or miscalculating the components that often matter more.

After analyzing over 400 offer comparisons at SmithSpektrum, here's how to actually calculate and compare total compensation[^1].

The Components of Total Compensation

Total compensation isn't just your paycheck. It's the sum of everything of value you receive.

Component Description Predictability
Base salary Fixed cash, paid regularly High
Annual bonus Performance-based cash Medium
Signing bonus One-time cash at start High
Stock/Equity Company ownership Low to High
Benefits Insurance, 401k, perks Medium
Other Relocation, stipends, etc. Varies

The formula seems simple:

Total Comp = Base + Expected Bonus + Equity Value + Benefits Value

But each component has nuances that change its real value.

Base Salary: The Foundation

Base salary is the only guaranteed component. It's what you'll actually receive regardless of company performance, your performance ratings, or stock price movements.

Because it's guaranteed, base salary should be weighted more heavily than variable compensation. A rule of thumb: $1 of base is worth roughly $1.10-1.20 of expected bonus and $1.25-1.50 of expected equity value (accounting for risk).

When comparing base salaries, adjust for taxes if offers are in different states. A $200K base in Texas ($0 state income tax) is worth more than $200K in California (~10% marginal rate).

Location Effective Base (Post State Tax)
$200K in Texas $200K
$200K in Washington $200K
$200K in California ~$180K
$200K in New York City ~$176K

Bonuses: Expected vs. Maximum

Bonus structures vary significantly. What matters is expected value, not the maximum possible payout.

Annual Bonus

Most companies express bonus as "target percentage"—the bonus you'll receive at expected performance.

Bonus Term What It Means
15% target You'll likely receive 15%
0-30% range Average is probably 15%, varies with performance
Up to 20% Maximum is 20%; expected is often 10-15%

To calculate expected bonus value, ask: "What percentage of employees hit target bonus?" and "What's the average payout as a percentage of target?"

At most companies, average payout is 90-110% of target. At aggressive companies, it might be 80-120%. Use the midpoint as your expected value.

Expected Annual Bonus = Base × Target % × Expected Achievement %

Example: $180K base × 15% target × 100% expected = $27K expected annual bonus

Signing Bonus

Signing bonuses are one-time payments. Don't annualize them for comparison—instead, amortize them over your expected tenure.

If you plan to stay three years, a $60K signing bonus adds $20K per year to your effective compensation. If you stay one year, it's worth the full $60K in that year.

Most signing bonuses have clawback provisions requiring repayment if you leave within 12-24 months. Factor this into your math.

Equity: Where Most People Get It Wrong

Equity is where offer comparisons go sideways. The number companies quote is rarely the number you'll receive.

Public Company RSUs

RSUs (Restricted Stock Units) at public companies are the most predictable equity form. They're worth the stock price at vesting.

Information Needed How to Get It
Number of RSUs Offer letter
Current stock price Public markets
Vesting schedule Offer letter

Calculate annual value:

Annual RSU Value = (Number of RSUs ÷ Vesting Years) × Current Stock Price

Example: 1,000 RSUs over 4 years at $150/share = 250 shares × $150 = $37,500/year

The complication: stock prices change. For comparison purposes, use current price as your baseline. For risk assessment, consider whether you believe the stock will rise or fall.

Conservative approach: discount RSU value by 10-20% when comparing to cash, reflecting price uncertainty.

Private Company Options

Stock options at private companies are much harder to value. You need:

Information Why It Matters
Number of options Your share count
Strike price What you pay to exercise
Fully diluted shares outstanding Your percentage ownership
Latest 409A valuation Current "paper" value
Latest preferred price What investors paid
Vesting schedule When you get them

Calculate your ownership percentage:

Ownership % = Your Options ÷ Fully Diluted Shares × 100

Example: 50,000 options ÷ 20,000,000 shares = 0.25% ownership

Then estimate value. This is where it gets speculative.

Paper Value = Options × (Current Value Per Share - Strike Price)

If current 409A is $2/share and your strike is $0.50:

50,000 × ($2.00 - $0.50) = $75,000 paper value

But this isn't cash. To convert to expected value, multiply by probability of liquidity and discount for time and risk.

The Startup Equity Discount

Startup equity should be heavily discounted because most startups fail.

Company Stage Probability of Meaningful Exit Discount to Apply
Pre-seed 5-10% 85-95%
Seed 10-15% 80-90%
Series A 15-25% 70-85%
Series B 25-35% 60-75%
Series C+ 35-50% 50-65%
Pre-IPO 60-80% 20-40%

A risk-adjusted valuation:

Expected Equity Value = Paper Value × Probability of Exit × Expected Exit Multiple Adjustment

Example: $75,000 paper value at Series A with 20% exit probability = $15,000 risk-adjusted value

For comparison purposes, treat startup equity as a lottery ticket, not guaranteed compensation. If a startup offer shows "$200K total comp" with $120K in equity, your risk-adjusted comp might be closer to $100-130K.

Benefits: The Hidden Compensation

Benefits often add $15,000-60,000 in annual value. Don't ignore them.

Healthcare

The value of health insurance depends on your situation:

Scenario Approximate Annual Value
Single, healthy $6,000-10,000
Single, uses healthcare regularly $10,000-15,000
Family coverage $18,000-30,000
Family with specific healthcare needs $25,000-45,000

What to compare: monthly premium cost to you, deductible amounts, out-of-pocket maximums, and whether your preferred doctors are in-network.

401(k) Match

401(k) matching is free money—don't leave it on the table.

Match Structure Annual Value (max contribution)
100% of 6% Up to $13,200 (at $220K base)
50% of 6% Up to $6,600
100% of 4% Up to $8,800
No match $0

Calculate based on your actual expected contribution:

401k Value = Your Contribution × Match Rate (up to match cap)

Other Benefits

Benefit Typical Value
Unlimited PTO Hard to value; depends on culture
Defined PTO (20+ days) $5,000-15,000
Remote work $5,000-15,000 (commute savings)
Meals provided $3,000-5,000
Wellness stipend $1,000-3,000
Learning budget $2,000-5,000
Equipment stipend $1,000-3,000
Parental leave Priceless when you need it

Some benefits are hard to monetize but matter. Parental leave, mental health support, and flexibility are valuable even if they don't appear on a spreadsheet.

The Comparison Framework

Now put it all together.

Step 1: Create the Comparison Table

Component Company A Company B
Base salary
Expected annual bonus
Signing bonus (amortized)
Equity (annual, risk-adjusted)
401(k) match
Health insurance value
Other benefits
Total Annual Comp

Step 2: Fill in the Numbers

Let's work through a real example:

Company A: Big Tech

  • Base: $195,000
  • Bonus: 15% target = $29,250
  • Signing: $50,000 (amortized over 3 years = $16,667)
  • RSUs: 800 over 4 years at $150 = $30,000/year
  • 401(k): 100% of 6% = $11,700
  • Healthcare: Family = $25,000
  • Other: $3,000

Company B: Series B Startup

  • Base: $175,000
  • Bonus: 10% target = $17,500
  • Signing: $30,000 (amortized = $10,000)
  • Options: 80,000 options, $8M 409A, $2M paper value, risk-adjusted ~$600K = $150K over 4 years = $37,500/year (but this is highly speculative)
  • 401(k): 50% of 6% = $5,250
  • Healthcare: Family = $22,000
  • Other: $2,000
Component Company A Company B
Base $195,000 $175,000
Bonus $29,250 $17,500
Signing (amortized) $16,667 $10,000
Equity (risk-adjusted) $30,000 $37,500*
401(k) match $11,700 $5,250
Healthcare $25,000 $22,000
Other $3,000 $2,000
Total $310,617 $269,250

*The startup equity number is speculative. At face value, the startup might claim $150K in annual equity value—but that's paper value with huge uncertainty.

Step 3: Apply Risk Weighting

Create a risk-adjusted comparison:

Guaranteed Annual Value = Base + (Signing ÷ Tenure)

Expected Variable = Bonus + Equity + Benefits

For Company A: $211,667 guaranteed + $98,950 expected = $310,617

For Company B: $185,000 guaranteed + $84,250 expected = $269,250

If you're risk-averse, weight guaranteed compensation more heavily.

Step 4: Consider Non-Financial Factors

After financials, consider:

Factor Company A Company B
Career growth Limited at BigCo High if startup succeeds
Learning opportunity Narrow but deep Broad but chaotic
Work-life balance Generally better Probably worse
Job security Higher Lower
Upside potential Capped Uncapped

Special Situations

Refreshers and Promotions

At big tech companies, equity refreshers are significant. Ask about typical annual refresher grants—they can add $20K-100K+ annually after year one.

Company Type Typical Refresher
FAANG 50-100% of initial annual grant
Large tech 25-75% of initial annual grant
Mid-size 10-50%
Startup Often none (initial grant is the deal)

Factor expected refreshers into multi-year projections.

Equity Negotiation

Equity is often more negotiable than base salary. The leverage points:

What to Ask Typical Flexibility
More options/RSUs 20-50% more
Lower strike price Rarely moves
Accelerated vesting Sometimes
Extended exercise window Often
Refresher commitment Sometimes

The Golden Handcuffs Question

If you have unvested equity at your current company, factor that into your comparison.

True Cost of Leaving = Unvested Equity at Current Price

If you have $200K in unvested RSUs, a new offer needs to compensate for that loss—either through signing bonus, accelerated vesting, or enough upside to justify the forfeit.


The engineer who almost took the lower offer? Once we did the math properly—RSUs versus speculative options, benefits included, risk-adjusted—Company B was clearly better. She took B and, two years later, those RSUs are worth even more than we projected.

The numbers don't lie. But you have to calculate them correctly first.
