Job offers, explained like you're 5
The parts of a job offer in plain words, how to turn each offer into one yearly number, and what to ask before you accept. It never says which offer to take or what equity is worth.
Explain it like I'm 5
A job offer is more than its salary. It is like comparing two lunch boxes, not just the sandwich inside. Some parts are guaranteed, while others are targets or arrive later. Add each part the same way for every offer so the comparison is fair.
This explains. It does not advise.
Where all four AIs agree is the solid ground. Where they disagree is exactly what to ask the recruiter or HR, and a tax professional for equity. This guide never says which offer to take or what equity is worth. It is not tax or investment advice.

The parts of an offer
Five parts to add up the same way for every offer.
Base pay
Base pay is the guaranteed salary or hourly pay for doing the job. Check how often it is paid and whether overtime, extra pay for extra hours, applies.
What to compare
- Compare guaranteed yearly pay
- Compare pay dates and payment method
- Check whether overtime applies
Watch out for
- A salary does not always answer the overtime question
- Do not count possible overtime as guaranteed pay
Bonus
A signing bonus is extra cash connected to starting work, while a yearly or performance bonus may depend on results. A guaranteed bonus is promised under stated terms, but a target is an aim and may not be paid. Check whether leaving could require paying a bonus back.
What to compare
- Separate guaranteed cash from target bonuses
- Compare when each bonus is paid
- Compare written bonus conditions
Watch out for
- A target is not a guarantee
- A repayment term can reduce a signing bonus's value
- Performance conditions may affect payment
Equity
Equity can include stock options, which give a right to buy shares, and restricted stock, which is stock subject to conditions. A grant is the award, vesting means gaining ownership, a vesting schedule says when that happens, and a cliff is an early point before which nothing vests. Exercising an option means using the right to buy shares. Tax treatment depends on the equity type and your situation, so ask a tax professional.
What to compare
- Compare the equity type and grant documents
- Compare what vests each year
- Compare the vesting schedule and any cliff
Watch out for
- A grant is not the same as owned shares
- Unvested equity may be lost when employment ends
- Do not value equity or predict its price
Retirement benefits
A 401(k) or 403(b) plan lets a worker save through the job. An employer match is money the employer adds when the worker contributes, while another employer contribution may not depend on worker contributions. Vesting means earning the right to keep the employer's part.
What to compare
- Compare employer match terms
- Compare other employer contributions
- Compare when employer contributions vest
Watch out for
- A match may require your own contribution
- Employer contributions can follow plan terms
- Unvested employer money may not stay with you
Health and other benefits
Compare what the employer pays toward health, dental and vision coverage, and what the worker pays as a premium, the cost of coverage. Ask about health savings accounts and flexible spending accounts, which are accounts for eligible health costs. Also compare paid time off, life insurance, disability insurance and other benefits.
What to compare
- Compare employer payments toward coverage
- Compare worker premiums and paid time off
- Compare employer contributions to health accounts
Watch out for
- Coverage choices can have different worker costs
- Account eligibility depends on plan details
- Paid time off terms can differ
Rules to know
- Retirement plan contribution limit, 2026
- You can put up to $24,500 of your pay into a traditional or safe harbor 401(k) in 2026, the newest year the IRS lists. If the plan allows catch-up contributions, people age 50 or over at the end of the year can add $8,000 more in 2026 ($11,250 for ages 60 to 63). Your plan can set a lower limit.

- How employer contributions vest
- In a 401(k) or other qualified defined contribution plan (government and some church plans aside), employer contributions, matches included, must vest at least as fast as one of two schedules: all at once after 3 years of service (cliff vesting), or step by step until fully vested after 6 years (graded vesting). These are the longest a plan can use, and a plan can vest faster, even immediately.

- How stock options are taxed
- The IRS splits employee stock options into statutory options (incentive stock options and employee stock purchase plans) and nonstatutory options. A statutory option is generally not income when you get or exercise it, though exercising an incentive stock option can bring alternative minimum tax; you have income or a loss when you sell the stock. For most nonstatutory options there is no tax at grant, and the stock's value minus what you paid is income when you exercise.

How to turn an offer into one number, step by step
- Write the guaranteed yearly base pay and guaranteed cash
- Mark each bonus that is only a target
- List equity and retirement money that vests later
- Add employer retirement contributions you expect to receive and keep
- Add stated employer payments toward benefits
- Use the same categories and assumptions for every offer
Common mistakes
- Counting a target bonus as guaranteed can make an offer look larger than it is.
- Adding equity as cash today ignores vesting and changing value.
- Ignoring bonus repayment terms can hide a cost of leaving.
- Ignoring employer contribution vesting can overstate retirement value.
- Comparing health coverage without employer and worker costs misses part of compensation.
- Using different methods for different offers makes the yearly totals misleading.
Questions to ask, and points to negotiate
Ask the recruiter or HR, and a tax professional for equity.
- Is any bonus guaranteed or only a target, and when is it paid?
- Must I repay a signing bonus if I leave, and under what terms?
- What type of equity is offered, and what are its grant, vesting, and cliff terms?
- What employer retirement contribution can I receive, and when does it vest?
- What does the employer pay toward each health, dental, and vision choice?
- Which benefits begin immediately, and which require enrollment or a waiting period?
