Part Time Hourly to Salary Calculator

The three numbers behind a part time salary

Every part time salary comes from three inputs: the hourly rate, the hours in a normal week, and the paid weeks in a year. Multiply them and you have gross pay, before taxes and deductions.

yearly pay = hourly rate x hours per week x paid weeks

Say a job pays $18 an hour for 25 hours a week across 50 paid weeks. Weekly pay is 18 x 25 = 450 dollars. Yearly pay is 450 x 50 = 22,500 dollars. The monthly average is 22,500 / 12 = 1,875 dollars, and a biweekly paycheck, the kind most hourly jobs issue, is 450 x 2 = 900 dollars.

The weeks input is the one people fudge. Typing 52 out of habit overstates a 50 week job by 450 x 2 = 900 dollars, which is two weeks of groceries for a lot of households. Read the paid weeks off your stub, not off the calendar.

Worked example: $18 an hour at 25 hours a week

Here is that job in full, with the two comparisons most people skip.

At 25 hours a week for 50 paid weeks you work 25 x 50 = 1,250 hours a year. Gross pay of 22,500 dollars divided by 1,250 hours gives 18 dollars an hour, the rate you started with, which is a quick way to check that nothing slipped.

Next, the same rate at full time. A 40 hour week over 50 weeks is 40 x 50 = 2,000 hours, so 18 x 2,000 = 36,000 dollars. The part time schedule earns 22,500 / 36,000 = 62.5 percent of that and leaves 15 hours a week free. Whether the trade is worth it depends on what those 15 hours are for, and on costs that only appear when you work more, like childcare and a second commute.

Last, a cheaper full time job. At $15 an hour for 40 hours across 52 weeks the year is 15 x 40 x 52 = 31,200 dollars. That is 8,700 dollars more than the part time job in total, while paying $3 an hour less. Per hour worked, the part time job wins; per year, it loses. Both statements are true, and picking between them is the actual decision.

What counts as part time, and why the line matters

There is no single legal definition, but there is a widely used statistical one. The Bureau of Labor Statistics counts anyone who usually works fewer than 35 hours a week as part time, and 35 hours or more as full time. The agency is careful to say those labels exist for statistics, not for law.

Federal wage law is thinner than people expect. The Fair Labor Standards Act requires overtime at one and a half times the regular rate after 40 hours in a workweek, and it says nothing about part time status. An employer can schedule you for 34 hours and owe no overtime, and a 32 hour week can still be advertised as full time on a job listing.

The 30 hour line does matter in one place. The employer shared responsibility rules under the Affordable Care Act treat an average of 30 hours a week as full time for health coverage purposes, and the IRS explains the monthly hour tests. That is the reason so many retail and restaurant schedules land at 29 hours, just under the line.

The 2,080 hour trap that overstates a part time rate

Full time salary math assumes 2,080 hours a year: 40 hours a week for 52 weeks. Job postings divide salary by 2,080 to get an hourly figure, and people repeat that division on part time pay without noticing the mismatch.

Take a $30,000 part time salary at 25 hours a week for 50 weeks. The real hours are 25 x 50 = 1,250. The true rate is 30,000 / 1,250 = 24 dollars an hour. Divide by 2,080 instead and you get 30,000 / 2,080 = 14.42 dollars an hour, which understates the job by almost 10 dollars an hour and makes a decent offer look like a bad one.

Run the comparison honestly and the shape of the trade gets clear. A $30,000 full time job at 2,080 hours pays 14.42 an hour. A $30,000 part time job at 1,250 hours pays 24 an hour. Same money, 830 fewer hours, and no employer health coverage in most cases, which is the part the hourly number cannot show.

What common part time schedules pay

The table prices six schedules the same way the calculator does. Each row is the rate times the hours times the paid weeks, and the monthly column is the yearly figure divided by 12.

Two rows are worth a second look. The 29 hour row sits right under the 30 hour health coverage line and clears $30,000 a year, which is why that schedule is so common. The 32 hour row pays $1,840 more than the 29 hour row and still counts as part time under the federal statistical definition, so an employer can offer it without overtime or a full benefit package.

Unpaid weeks, school calendars and the 50 versus 52 gap

Paid weeks are where a part time estimate drifts from reality, because the gaps are rarely announced. A job that closes for two weeks over the holidays and does not pay for them is a 50 week job. A school year position that runs 38 weeks and spreads the pay over 12 months is a 38 week job with a smoothing trick on the paycheck.

The arithmetic is the same each time. At $18 an hour and 25 hours a week, 52 weeks gives 18 x 25 x 52 = 23,400 dollars, 50 weeks gives 22,500 dollars, and a 38 week school calendar gives 18 x 25 x 38 = 17,100 dollars. The spread between the best and worst of those is 6,300 dollars for identical hours in a working week.

Unpaid sick days and unpaid holidays belong in the same column. If you expect to miss six days a year at 5 hours a day, that is 30 hours, and 30 x 18 = 540 dollars off the yearly figure. Put your own number in the weeks field and the calculator will carry it through every result.

Two part time jobs, benefits and the honest comparison

Plenty of people stack two part time jobs instead of taking one full time one. The pay math is simple addition. Twenty hours a week at $17 is 340 dollars, fifteen hours at $15 is 225 dollars, so the week is 340 + 225 = 565 dollars and the year, at 52 weeks, is 565 x 52 = 29,380 dollars.

Overtime does not stack across employers. The 40 hour test in the Fair Labor Standards Act applies to each employer separately, so 20 hours plus 25 hours is 45 hours of work and zero overtime hours. Only a single employer pushing you past 40 owes the extra half time.

Benefits are where the two job plan usually loses. Health coverage, paid time off and any retirement match are tied to one employer, and a 20 hour schedule often qualifies for none of them. Add the costs that only exist because there are two jobs: a second commute, two sets of uniforms, two schedules to negotiate around. On the example above, if the second job costs $12 a day in gas and parking for three days a week, that is 12 x 3 x 52 = 1,872 dollars a year, which eats a large share of the 29,380 dollar total.

A fair comparison puts gross pay, hours, commute cost and benefits on one line each. The calculator gives you the first two; the last two are yours to add.
