$18 an Hour Is How Much a Year After Taxes?

What $18 an hour leaves after federal taxes

Forty hours at $18 pays 720 for the week, and 52 weeks of that is 37,440. The math is short: 18 x 40 = 720, then 720 x 52 = 37,440. Two federal charges come off before the money reaches a bank account: 2,864.16 of payroll tax and 2,312.80 of income tax for a single filer who takes the standard deduction.

Subtract both and 32,263.04 is left, which is 2,688.59 in an average month. Spread over 2,080 paid hours, take-home pay is 15.51 an hour, so each hour on the clock is worth 2.49 less than the rate on the offer.

Combined federal charges reach 5,176.96, or 13.83 percent of gross pay. That number sits below the 12 percent bracket on the last dollar: the 16,100 deduction keeps a slice of income clear of income tax, while payroll tax collects 7.65 percent from the first dollar.

Both directions check out: 5,176.96 / 37,440 = 0.1383, and 32,263.04 / 2,080 = 15.51. Every figure on this page is built from the same three numbers, so a change in hours, filing status or state rate moves the whole set together.

The payroll tax comes first: $2,864.16

FICA funds Social Security at 6.2 percent and Medicare at 1.45 percent, which adds to 7.65 percent. It ignores the standard deduction, dependents and filing status, so every hour of this job carries the same payroll charge.

On 37,440 of wages, Social Security takes 37,440 x 0.062 = 2,321.28 and Medicare takes 37,440 x 0.0145 = 542.88. The two add to 2,864.16, or 1.38 out of every hour worked.

The Social Security piece stops once wages pass the contribution and benefit base, which the Social Security Administration sets at 184,500 for 2026. A wage of $18 an hour never comes close, so the full 6.2 percent applies to all 37,440. Medicare has no ceiling, and its extra 0.9 percent surtax starts above 200,000 of wages, which is also out of reach at this rate.

Pay frequency changes the size of each bite without changing the yearly total: 55.08 from a weekly check, 110.16 from a biweekly one, 119.34 from a semi-monthly one and 238.68 from a monthly one.

A 1099 contractor pays both halves. Self-employment tax is 15.3 percent on 92.35 percent of net profit, which is 5,290.10 on this income, or 2,425.94 more than the employee share.

Federal income tax: $2,312.80 for a single filer

For 2026 the standard deduction is 16,100 for a single filer, 32,200 for a married couple filing jointly and 24,150 for a head of household, per the IRS inflation adjustments for tax year 2026. Take 16,100 from 37,440 and 21,340 is left to tax.

That 21,340 is taxed in layers. The first 12,400 is taxed at 10 percent, which comes to 1,240.00 (12,400 x 0.10 = 1,240.00). The next 8,940 faces 12 percent and adds 1,072.80 (8,940 x 0.12 = 1,072.80). The layers add to 2,312.80, which is 6.18 percent of gross pay although the last dollar sits in the 12 percent bracket.

Marital status changes this line more than most people guess at $18 an hour. A couple filing jointly deducts 32,200, which leaves 5,240 of taxable income and a bill of 524.00. A head of household deducts 24,150, which leaves 13,290 taxable and 1,346.80 of tax.

Only income tax changes with status. FICA stays at 2,864.16 in all three rows because payroll tax does not care how a worker files. The joint and head of household rows also leave out credits, such as the child tax credit, that a real return may claim.

The check you will see, week by week

A payroll system divides the year into equal slices. The figures below assume one job, the standard deduction, no state levy and no pretax deductions. Each row splits the yearly total across the number of deposits on that calendar.

Two arithmetic traps live in this table. A biweekly check of 1,440 is not half a month, because 26 of them make the year while 24 semi-monthly checks of 1,560 also make it. And a worker paid every two weeks gets two months a year with a third check, so those months hold 3,722.67 instead of 2,481.78.

Withholding is an estimate, not the final bill. The W-4 you file tells the payroll system how much to send, and a second job, a working spouse or a midyear raise can push the total either way. A refund in April means the checks were trimmed too much, not that the tax disappeared.

Short weeks, seasonal gaps and the part-time net

A shorter schedule cuts gross pay faster than it cuts tax, so each hour worked keeps more. The table shows the trade at four weekly hour counts, then the same effect from unpaid weeks off.

Twenty hours pays 18,720, which leaves only 2,620 of income above the 16,100 deduction, so income tax falls to 262.00 while FICA still takes 1,432.08. Each hour then clears 16.37, which is 0.86 more than a full-time week. The trade is steep: the 20-hour year brings home 15,237.12 less than the 40-hour year.

Unpaid weeks do the same work on the total. Forty hours for 46 paid weeks pays 33,120 gross, leaves 28,791.92 after 2,533.68 of FICA and 1,794.40 of income tax, and drops the year by 3,471.12 compared with 52 weeks. Forty-eight weeks nets 29,948.96, and 50 weeks nets 31,106.00.

Paid vacation is not a cut, since the leave is paid time. The gap above applies to seasonal shutdowns, unpaid leave and weeks with no shifts on the schedule. Notice that FICA never falls to zero: the deduction shields income tax alone, so a short year still hands 7.65 percent of its wages to payroll tax.

State and city tax on the same wage

State withholding rides on the same paycheck. Nine states collect nothing on wages, and the rest take a share that runs from near 1 percent to more than 10 percent at higher incomes. Three common shapes appear below, applied as flat rates for comparison.

The Pennsylvania Department of Revenue lists a flat 3.07 percent on wages, so 37,440 x 0.0307 = 1,149.41 and 31,113.63 is left. Illinois uses 4.95 percent, which takes 1,853.28 and leaves 30,409.76. The gap between those two states is 703.87 a year for the same job at the same rate.

Most states use brackets instead of one flat rate, and several add a local wage tax near 1 percent. A city tax of 1 percent would take another 374.40 from this year and pull monthly net down to 2,657.39. Use the table as a range of outcomes, then confirm the rate for your own address with the state revenue office.

An overtime hour at $27 keeps $21.69

Federal law requires 1.5 times the normal rate for hours beyond 40 in a week, a standard the Department of Labor Wage and Hour Division polices under the Fair Labor Standards Act. At $18 an hour that premium rate is 27.00.

Ten extra hours a week turn the 720 check into 990 (720 + 270 = 990), and 990 x 52 = 51,480 of gross pay for the year. FICA rises to 3,938.22 and taxable income to 35,380, which puts federal income tax at 3,997.60. Net pay lands at 43,544.18, or 11,281.14 more than the flat 40-hour year.

The extra dollar behaves differently from the base dollar. An overtime hour loses 2.07 to FICA and 3.24 to the 12 percent bracket, leaving 21.69. A straight hour loses 1.38 and 2.16, leaving 14.46. The premium adds 7.23 an hour to take-home, not the full 9.00 difference in gross pay.

Overtime is counted one workweek at a time. A 50-hour week followed by a 30-hour week pays premium for ten hours, while a two-week schedule of 80 hours pays none if neither week passes 40. Multiply a typical week by 52 only if the schedule runs all year, since 50-hour weeks for twelve months are 2,600 hours.

What a raise is worth, and where a 401(k) fits

A dollar an hour is 2,080 a year at a full-time schedule, and the tax system takes a share of it. Moving from $18 to $19 lifts gross pay by 2,080, because 19 x 2,080 = 39,520. FICA rises to 3,023.28, income tax to 2,562.40, and the year leaves 33,934.32. The raise is worth 1,671.28 in the bank, not 2,080.

The 401(k) is a different trade. A deposit of 4 percent, or 1,497.60, comes out before income tax is figured. Taxable income falls to 19,842.40, federal income tax falls to 2,133.09 and take-home lands at 30,945.15. The bank account drops by 1,317.89 while the retirement account gains 1,497.60, and FICA stays at 2,864.16 because payroll tax is figured on gross wages.

A health premium taken through a cafeteria plan works the other way. It comes out before income tax and FICA both, so it lowers the 7.65 percent payroll charge as well. An HSA contribution made through payroll gets the same treatment. A 401(k) does not.

Payroll tax does not come back. When a short year lands under the 16,100 deduction, the income tax withheld is returned at filing, but the 7.65 percent already sent stays put. Compare these figures with a full pay stub before signing a lease, and treat any number here as a planning estimate.
