Annual Salary Calculator

Background.

One offer pays $28 an hour; another pays $58,000 a year. To compare them you need both in the same unit, and the usual shortcut is 2,080: the hours in 52 paid weeks of 40 hours. At that rate $28 an hour comes to $58,240, so on paper the hourly job pays $240 more. Whether it really does depends on what the shortcut hides — whether the hourly job pays for holidays and vacation, how many hours a week you will actually be scheduled, and whether the salaried job quietly expects 50-hour weeks.

Enter one pay figure in whatever form you have it — an hourly wage, a weekly or biweekly paycheck, a semimonthly or monthly amount, or a yearly salary — and it is turned into a yearly total, then sliced back into all six periods. You set the hours per week and the weeks per year, so the same conversion works for a full-time salaried employee, a part-timer on 25 hours and a contractor who bills 47 weeks a year.

Most errors in this arithmetic come from two pay schedules with confusingly similar names. Biweekly means every other week: 26 paychecks a year. Semimonthly means twice a month on fixed dates, usually the 1st and 15th or the 15th and the last day: 24 paychecks a year. Divide a $60,000 salary by the right count and the check is $2,307.69 or $2,500.00. Divide by the wrong one and a budget, a loan application or a salary comparison is off by about 8%.

Every figure is gross pay — what the employer pays before income tax withholding, Social Security and Medicare, retirement deferrals and insurance premiums come out. The conversion also pays every hour at the same rate, so overtime premiums for hourly work beyond 40 hours a week are not included unless you build them into the hours you enter.

What is annual salary calculator?

Annual salary is gross pay for one year: the figure on an offer letter and in a salary negotiation, before any taxes or deductions. For a salaried employee it is fixed by contract, and each paycheck is a slice of it. For an hourly worker it is derived — wage × hours paid per week × weeks paid per year — and it moves whenever the schedule does. The paychecks it splits into are defined by count rather than by calendar: 52 weekly, 26 biweekly, 24 semimonthly or 12 monthly payments in a standard year. Hourly equivalents for full-time work conventionally assume 2,080 hours, which is 40 hours × 52 weeks with paid holidays and vacation counted as time worked. Federal pay administration uses 2,087 hours instead, a figure that reflects the average length of a year with leap years included, so a federal hourly rate is a few cents lower than the private-sector conversion of the same salary.

How to use this calculator.

1. 01Type the amount into Pay amount exactly as it appears on your pay stub, offer letter or job posting, before deductions. A take-home figure from your bank statement will understate the salary, because taxes and benefit premiums have already been removed.
2. 02Choose the Pay frequency that matches how that amount is paid. Paid every other Friday is biweekly; paid on fixed dates such as the 15th and the last day of the month is semimonthly. If your stub shows the start and end of the pay period, count the days: 14 means biweekly, about 15 means semimonthly.
3. 03Set Hours worked per week to the hours you are paid for. If you are salaried and want an effective hourly rate, enter the hours you actually work instead. Leave it at 40 for a standard full-time conversion.
4. 04Set Weeks worked per year. Keep 52 if your vacation and holidays are paid; subtract unpaid weeks if you are hourly and unpaid when off, or use your realistic billable weeks if you freelance.
5. 05Read the annual figure first, then the period you need. Biweekly, semimonthly and monthly are always one 26th, one 24th and one 12th of the annual total, whatever you entered for weeks.

The formula.

Every conversion passes through the annual figure. The first step builds it from what you entered: an hourly wage is multiplied by hours per week and weeks per year (A = w × h × W); a weekly amount by weeks per year; a biweekly check by 26; a semimonthly check by 24; a monthly amount by 12; and an annual amount is taken as it stands. The second step divides the total back out: hourly = A ÷ (h × W), weekly = A ÷ W, biweekly = A ÷ 26, semimonthly = A ÷ 24 and monthly = A ÷ 12.

The two halves of that list are tied to different things. Hours and weeks affect only the hourly and weekly figures, because those describe time actually worked. Biweekly, semimonthly and monthly use fixed counts, because they are payroll schedules: a salaried employee who takes four unpaid weeks still receives 26 biweekly checks, only smaller ones. Set weeks to 48 and the weekly line becomes pay per working week while the biweekly line is the annual total spread over the year's 26 paydays, so the second is no longer twice the first.

At the defaults h × W = 2,080, so an hourly wage times 2,080 is the annual salary and a salary divided by 2,080 is the hourly equivalent. The ratio between the two common paycheck schedules is fixed at 26 ÷ 24: a semimonthly check is 8.33% larger than a biweekly check on the same salary, and a biweekly check is 7.69% smaller than a semimonthly one.

The model is linear and flat. Every hour is paid at one rate, so overtime premiums, shift differentials, commissions and bonuses are left out unless you fold them into the amount or the hours. It also assumes the standard 26 biweekly and 52 weekly paydays, although a calendar year occasionally contains a 27th biweekly or a 53rd weekly payday.
