If you're still earlier in the process, see how to prepare for a job interview first. This guide picks up once you have an offer in hand, or more than one.
Most candidates compare job offers on base salary alone. Salary is often the least differentiating number once you account for equity vesting schedules, employer health insurance contributions, 401k matching, commute costs, and differences in expected hours. A role offering $7,000 less per year can be worth more in take-home pay, career capital, and day-to-day quality of life than the one with the higher headline figure.
A structured framework prevents the most common mistake: accepting the highest number and realising six months later it was the wrong choice. This guide walks through each component methodically, including the factors that compound most over time and are hardest to quantify in the moment.
Start With True Total Compensation
Calculate total compensation before comparing anything else:
Total comp = base salary + expected annual bonus + annualised equity value
Each component needs adjusting before you add it up.
Bonus: Use the target percentage, not the maximum. A $148,000 base with "up to 25% bonus" is not a $185,000 package if the actual target payout is 11%. The expected value is $164,280. Maximum bonus figures are marketing language. Target figures are planning figures.
Equity: Annualise the total grant value over the vesting period. A $116,000 RSU grant vesting over four years contributes $29,000 per year to your total compensation. Adjust further for the difference between public and private equity, covered in the section below.
Signing bonus: One-time only, and almost always accompanied by a clawback clause requiring repayment if you leave within 12 months. Do not add it to annual compensation. Treat it separately as a one-off cash benefit with a condition attached.
Here is how the maths plays out in practice. Two fictional offers:
Offer A: $134,000 base, $16,080 expected bonus (12% target), $22,500 annualised RSUs = $172,580 total comp
Offer B: $142,000 base, $8,520 expected bonus (6% target), $11,800 annualised options (adjusted for liquidity risk) = $162,320 total comp
The higher-salary offer delivers over $10,000 less per year once all components are included. The ranking flips entirely.

The Benefits That Move the Number More Than People Expect
Health insurance
Employer-sponsored premiums vary significantly across companies. A role paying $5,200 less annually with fully covered family health insurance may deliver more take-home than the higher-salary role where the employee contribution is $570 per month ($6,840 per year). Do the subtraction before comparing base salaries.
401k match
A 4% employer match on a $118,000 salary is $4,720 per year in additional compensation that does not appear in the headline offer. Vesting schedules matter as much as the match rate. A three-year cliff vesting schedule means you forfeit the entire employer match if you leave before month 36. Compare the match percentage and the vesting terms, not just the match percentage in isolation.
PTO and flexibility
Monetise PTO differences directly. Ten additional days at a $118,000 salary is approximately $4,538 in paid time off. Remote working versus hybrid versus in-office is harder to monetise but commute cost and time are real values, covered in the Hidden Costs section below.
Learning and development budget
Often dismissed but significant in compounding terms. A $3,200 annual L&D budget with conference attendance adds face-value cash alongside skills that directly affect earning trajectory in subsequent roles. Compare this line item explicitly rather than treating it as a perk.
How to Actually Evaluate Equity
Public company RSUs
RSUs at a publicly listed company are the more straightforward of the two types. Value the grant at the current share price, divide by the vesting period, and factor in the concentration risk of holding a significant position in your own employer. One detail many candidates miss: RSUs vest as ordinary income, taxed at your marginal rate at the moment of vesting, not at capital gains rates. Budget for the tax liability at vest; the net value is lower than the gross.
Private company options
Options at a private company require more information to value honestly. Ask for four figures: the strike price, the last 409A valuation (fair market value per share set by an independent appraiser), the liquidation preference stack, and total shares outstanding to calculate your ownership percentage.
The spread between strike price and 409A valuation is your paper gain per share, realisable only at a liquidity event that may be three, seven, or ten years away. A $480,000 paper grant at a company that has not grown headcount in two years and carries a 2x participating preferred stack is not equivalent to a $220,000 grant at a company with strong revenue momentum and a clean cap table.
The standard one-year vesting cliff means the year-one value of any options grant is zero, regardless of the headline figure.
For UK employees, EMI options carry significant income tax and capital gains advantages on qualifying grants. For US employees, QSBS exemption can make early-stage equity held for five or more years tax-free up to $10 million. Ask an accountant before the vesting date, not after.
Any company unwilling to share these figures when asked directly is presenting you with an unvalued asset. That refusal is itself a signal.
Career Trajectory — The Factor That Compounds Most
Manager and team quality
Who you report to in your first few roles shapes your professional network, your working habits, and your reference base more than company brand does. Before accepting, ask your potential manager how long they have been in the role, what happened to their last three direct reports, and what success in year one looks like in concrete terms. Vague answers to specific questions are informative.
Company trajectory signals
For private companies and startups, the information you need is largely public. LinkedIn headcount trend over the past 12 months shows whether the company is growing or contracting. Crunchbase shows the last funding date and round size. Glassdoor review sentiment, particularly from employees who recently left, surfaces cultural patterns that interviews do not reach. Headcount declining while a company publicly claims growth is worth investigating before accepting.
Role as a market signal
Some roles at specific companies are well-established stepping stones in a given field. Others carry titles that sound senior but do not transfer well to the next search, because the company brand is weak or the scope is narrower than it appears. Ask yourself which doors this role opens in three years that the alternative does not.
Early versus mid versus late career
In the first five years, optimise for learning rate and network quality ahead of salary. The skills built between years two and five determine the ceiling reached between years ten and fifteen. In mid-career, balance compensation with trajectory. At senior level, stability and total compensation carry more weight relative to speculative growth upside.
The Hidden Costs Most Candidates Ignore
Effective hourly rate
Divide annual salary by actual expected hours worked per year. A $131,000 role with a 61-hour working week has an effective hourly rate of approximately $41.30. A $114,000 role with a 40-hour week works out at $54.81 per hour. The lower salary pays more per hour worked by a margin that changes the comparison entirely. Ask directly about expected hours during the offer stage; how a company answers that question is also informative.
Cost of living adjustment
If the offers are in different cities, apply a cost of living index before comparing headline figures. A $118,000 salary in Edinburgh does not compare directly with $138,000 in London once rent, commute costs, and daily expenditure differences are factored in. Several public indices allow direct city-to-city comparison.
Commute true cost
Time: a 43-minute commute each way equals approximately 7.2 hours per week, or around 317 hours per year. At a $55 effective hourly rate, that represents roughly $17,435 in time annually. Add direct costs on top: monthly transit pass, parking fees, fuel, and vehicle wear where applicable. The full picture often changes which offer looks more attractive.
Using a Competing Offer to Negotiate
Once you have two or more offers, you have genuine leverage. Tell your preferred employer that you have a competing offer and that you would prefer to join their company if they can close the gap. Give them a specific number rather than asking them to "make their best offer".
For the exact scripts and timing for this conversation, see how to negotiate salary. If you want a suggested range before you name a number, run it through the free Salary Negotiation Calculator first.
Beyond base salary, the following are commonly negotiable: signing bonus, equity grant size, remote working frequency, start date, and occasionally title where the company has flexibility on banding. Benefits are rarely negotiable at large companies but more often moveable at smaller ones.
Two rounds of negotiation is typically the practical limit before goodwill starts to erode, particularly at companies with fewer than 200 employees.
Get every commitment in writing before accepting: offer letter components, equity grant documentation, start date, and any verbal agreements about role scope or review timing. Verbal commitments have no standing if the hiring manager changes or the team restructures after you join.
The Regret Minimisation Test
When the numbers are genuinely close, the quantitative framework has done most of its work. The remaining decision is usually about which factors you are actually weighting most, versus which ones you said you would weight when you built your comparison.
Ask yourself: in five years, which choice would you regret more? The answer generally surfaces the priorities your scoring has understated and gives you a clearer signal than further analysis will.
If you have been weighing the options for more than a week and the gap has not changed, the offers are probably closer in real value than they feel. Set a deadline and decide. The anxiety resolves faster once the decision is made.
FAQ
How do you compare job offers with different salaries and benefits?
Start by calculating total compensation for each offer: base salary plus annual bonus plus annualised equity value. Then factor in benefits costs — a role with a lower salary but fully paid health insurance and a strong 401k match may be worth more in take-home terms. Use a structured scoring framework to compare non-financial factors like growth potential and stability alongside the numbers.
Should I always take the highest-paying job offer?
Not necessarily. A higher salary in a role with limited growth, a toxic culture, or a company in financial difficulty may cost more in the long run than a slightly lower offer at a company where you will develop faster, build a stronger network, and have more security. Early in a career, learning and trajectory often matter more than the immediate number.
How do I compare equity offers from different companies?
Public company RSUs are easier to value — use the current share price and the vesting schedule. Private company options are harder: you need the strike price, the last 409A valuation, and an honest view of the likelihood and timeline to liquidity. A large options grant at a company with a heavy liquidation preference stack may be worth significantly less than it appears.
How do I use a competing offer to negotiate without burning a relationship?
Be direct but not adversarial. Tell your preferred employer that you have a competing offer and that you would prefer to accept theirs if they can close the gap. Give them a specific number to match or beat. Most hiring managers respect a candidate who is transparent about their situation — what damages relationships is using invented offers or making ultimatums without intent to follow through.
What should I ask before accepting a job offer?
Ask for the full equity breakdown in writing: grant size, vesting schedule, cliff, strike price if options, and last 409A if private. Confirm the performance review cadence and how compensation adjustments work. Ask about the company's recent headcount trajectory and last funding round if it is a startup. Get the full benefits summary including health insurance premiums and 401k match details.
