The offer letter is open, and one number is doing all the talking. That figure is what you will repeat to your family tonight.

It is one line of a longer document. The other lines decide how much of it you keep, and what else arrives. Two offers with the same salary can differ by thousands of dollars a year, and the gap is rarely visible on the first page.

Gross Pay And What Reaches Your Bank

Gross pay is your salary before anything comes out. Take-home pay, also called net pay, is what lands in your account. The gap surprises most new workers.

Four things come out. Federal income tax withholding, estimated from the Form W-4 you fill in on day one. State income tax withholding, if your state has one. The FICA employee share, fixed by law at 6.2 percent for Social Security plus 1.45 percent for Medicare, so 7.65 percent together. And pre-tax deductions, money sent to your health premium or retirement account before tax is figured.

Pre-tax cuts both ways. That money lowers the income your tax is figured on, so it costs you less than its face value. Health premiums taken this way also skip Social Security and Medicare tax. Retirement contributions do not.

The first paycheck shocks people for a plain reason. They divided the salary by twenty-six, for the pay periods in a year, and subtracted nothing.

The Match Is Pay You Have To Claim

Many employers add money to your retirement account when you add your own. That is the match, a structure rather than a fixed amount. A common shape is fifty cents for every dollar you contribute, up to six percent of your pay.

Run it on an illustrative $60,000 salary. Contribute six percent, $3,600, and the employer adds $1,800. Contribute nothing and it adds nothing. You did not save $3,600. You turned down $1,800 of pay.

Vesting is the catch. It is when the employer's money becomes yours to keep if you leave. Your own contributions are yours immediately, always. The employer's share can sit on a schedule: none of it yours until a set year, three at most (cliff vesting), or a rising share year by year, up to six (graded vesting). A match you have not vested in is not yours yet.

Health Coverage And The Deductible Bet

A health plan has a monthly premium, the fee for having coverage at all. The employer usually pays most of it, and your share comes out of each paycheck. Say a $650 premium where the employer covers $500, illustrative numbers. That $6,000 a year appears nowhere in your offer letter.

The deductible is what you pay for care yourself each year before the plan starts covering most of the cost.

One option costs you $60 a month with a $3,000 deductible. Another costs $200 a month with a $750 deductible. The second takes $1,680 more a year and saves up to $2,250 in a year you get sick. Neither plan is better. They are different bets, and the winner depends on how much care you use.

Time Off Varies More Than You Think

Paid time off is where two identical salaries quietly separate. Almost none of it is standardized.

Ask four things. Does time accrue, a few hours each pay period, or is the year granted up front? Does unused time roll over or expire? Do unused days get paid out when you leave? Is sick leave separate, or does calling in sick spend a vacation day?

Two weeks that expire are not the same benefit as two weeks that roll over and pay out.

Exempt, Non-Exempt, And Your Real Hourly Rate

Federal law splits jobs in two. Non-exempt means overtime is owed: at least one and a half times your regular rate for every hour past forty in a workweek. Exempt means it is not owed, however long the week runs.

Exempt is not a label the employer simply chooses. The job has to pay a fixed salary at or above a level the Department of Labor sets, and the duties have to fit categories like executive or professional. A job title alone decides nothing.

This is why a salaried offer can pay worse than an hourly one. Take the illustrative $60,000. Over forty hours a week that is about $29 an hour. Over fifty-five hours it is about $21. Ask what the week actually looks like.

If The Offer Includes Equity

Some offers add shares in the company. Treat them as a separate question from pay.

Equity vests the way a match does, often over four years, with a cliff at one year, so leaving in month eleven gets you nothing. If the company is private, the shares cannot be sold on any market. You may hold something valuable. You cannot pay rent with it.

Building One Number You Can Compare

Turn each offer into one figure. Start with the salary. Add the employer match you will actually receive. Add the employer's yearly share of your premium. Subtract commuting and any relocation you pay yourself.

The illustrative $60,000 job with an $1,800 match and $6,000 of employer premium is a $67,800 job. Subtract $2,400 of driving and it is $65,400. A $63,000 offer with a ten-minute walk can beat it.

Before you sign, ask for four things: the match formula and vesting schedule, the plan summary with premiums and deductibles, the time off policy in writing, and whether the role is exempt. None of that is rude. Recruiters answer it daily, and the answers already exist as files somebody can email you in five minutes. Asking costs one email. Not asking can cost a year of the difference.
