Formula

annual = hourly × hoursPerWeek × weeksPerYear

How the calculation works

An hourly rate is a ratio, so turning it into a salary is a chain of multiplications that cancel units: rate times hours in a week times weeks in a year. At 40 hours and 52 weeks the year is 2,080 hours, so 18 an hour is 37,440 and 25 an hour is 52,000. Nothing compounds here; double the rate and every figure below doubles with it.

The weeks-per-year figure is the lever people leave untouched, and leaving it at 52 quietly overstates the year. Fifty-two assumes you are paid for every week including holidays; an hourly worker who takes two weeks unpaid is closer to 50, which drops the 18-an-hour year to 36,000. The tool refuses more than 168 hours in a week, which catches a mistyped shift.

The derived figures carry their own assumptions. Monthly is the year divided by twelve, so 18 an hour is 3,120 a month, not the 2,880 you get by multiplying the weekly 720 by four, because a month is about 4.33 weeks. The daily figure divides the week by five, which silently assumes a five-day week and is wrong for a four-day rota.

Common questions

What if I take unpaid leave?

Lower the weeks figure, to 50 for example, and the year becomes realistic.
