A friend of mine turned down a $160,000 base salary offer to take a $140,000 one. Her family thought she was making a mistake. She ended up making more money in year one by a significant margin. The difference was total compensation, and most people still don’t know how to calculate it correctly before signing an offer letter.
This post is about fixing that. Not in the abstract, but with the actual math.
Why base salary tells you almost nothing
At established tech companies, base salary is often 40 to 60 percent of your real annual pay. The rest comes from equity, bonuses, and benefits with actual dollar value. When you compare offers using only base salary, you’re comparing partial numbers.
This is not a trick companies play. Most recruiters present every component openly if you ask. The problem is candidates don’t always know which questions to ask, or they accept that the components exist without actually adding them up.
The Bureau of Labor Statistics Occupational Employment and Wages data tracks base wages, not total compensation. So when you see median software engineer salary figures in the news, those are almost always base-only numbers. The real picture is different.
The components, one at a time
Base salary. Fixed. Paid every two weeks or twice a month. This is the number everyone talks about. It’s also the number that determines your overtime eligibility, your 401(k) match calculation, and usually your bonus target percentage.
Annual bonus. Usually expressed as a percentage of base. A 15% target bonus on a $150,000 base is $22,500. But “target” means you get it at 100% performance. Strong years pay more. Bad years pay less or nothing. At many companies, bonuses are not guaranteed even if you hit your goals. Read the offer letter language carefully here.
RSUs (restricted stock units). A grant of company shares that vest over time. The standard schedule is four years with a one-year cliff, meaning you get nothing until your first anniversary, then 25% at once, then smaller amounts quarterly or monthly after that. A $200,000 RSU grant vesting over four years is roughly $50,000 per year, but the real value depends on the stock price when each batch vests.
Stock options. More common at startups than public companies. Options give you the right to buy shares at a fixed price (the “strike price”) set at the time of grant. They’re only worth something if the stock price rises above that strike price and the company either goes public or gets acquired. They can be worth a lot. They can also be worth zero. I’ve seen both.
Signing bonus. One-time payment, usually in your first paycheck or shortly after joining. Ranges from $5,000 to well over $100,000 at senior levels in competitive markets. Most signing bonuses have clawback clauses requiring repayment if you leave within 12 to 24 months. Factor this in if you’re considering leaving soon.
401(k) match. Free money, often overlooked. If a company matches 4% of your salary and your base is $150,000, that’s $6,000 per year they’re contributing to your retirement. It takes time to vest, but it’s real value.
Benefits. Health insurance is the big one. Individual coverage at a good employer can save you $10,000 to $20,000 per year versus buying on the individual market. Some companies also offer gym stipends, home office budgets, free meals, commuter benefits, or childcare support. These are worth tallying up even if they feel like perks.
How to calculate year-one TC on a real offer
Say you have an offer with these terms: $150,000 base, 15% target bonus, $200,000 RSU grant over 4 years, $30,000 signing bonus, 4% 401(k) match, and health insurance worth approximately $18,000 per year in saved premiums.
Year-one math: $150,000 (base) + $22,500 (bonus at target) + $50,000 (RSU year-one tranche) + $30,000 (signing) + $6,000 (401k match) + $18,000 (health insurance) = roughly $276,500 in total year-one compensation.
Year two will be lower because the signing bonus is gone, unless the stock price appreciated meaningfully on the RSU tranche. This is why TC comparisons are usually done over four years, not one.
Comparing two offers without losing your mind
The only fair comparison is four-year total compensation assuming flat stock price. This removes the temptation to assume your startup RSUs will 10x (they might, but you can’t count on it) while also not penalizing public company equity unfairly.
Put the offers side by side in a spreadsheet. Four rows: base x 4, bonus x 4 (use the target, not the max), RSU grant at current/expected value, signing bonus (usually year one only). Total each column. Then add a notes row for benefits value and vesting schedule differences.
Sometimes the lower base salary offer wins this comparison. Sometimes it doesn’t. The point is you’re comparing the actual number, not the number on the headline line of an offer letter.
The trap people don’t see coming
State income tax. If you’re comparing a $250,000 TC offer in Texas (no state income tax) against a $280,000 TC offer in California (state income tax above 13% at high incomes), the California offer might net you less take-home pay despite the higher number.
I’m not saying to avoid California jobs for this reason. But factoring in after-tax take-home pay is the correct way to think about this, especially if you’re choosing between cities as part of the decision.
The other trap: refresher grants. Many companies give additional RSU grants at year two or three based on performance. These don’t appear in your original offer letter, but they meaningfully affect total compensation over a five- or six-year tenure. If you’re talking to employees at the company already, ask how refreshers typically work. It’s a reasonable question.
Negotiating TC, not just base
Most candidates negotiate base salary because it feels like the most concrete lever. But RSU grants, signing bonuses, and performance bonuses are also negotiable at most companies, often with more flexibility than base.
If a company says their base band is firm, ask about the signing bonus or the equity grant size. If they’ve maxed your band on base, there’s often room in the signing bonus budget. This is standard practice. Recruiters expect it. LinkedIn’s Economic Graph research consistently finds that workers who negotiate receive better outcomes across all TC components, not just salary.
The biggest mistake is thinking the offer letter is a fixed document. It isn’t. It’s the opening position. Most of it is negotiable, and asking doesn’t cost you the offer in the overwhelming majority of cases. I can’t prove the exact percentage on that, but the anecdotal evidence from everyone I’ve talked to who has negotiated is pretty consistent: companies expect you to.
