Salary Calculator

Convert a pay rate to every other pay period — hourly, daily, weekly, bi-weekly, semi-monthly, monthly, and annual — based on the hours and weeks you work.

Quick Facts

Formula
Annual pay = rate x periods worked per year
For hourly pay that is hourly rate x hours/week x weeks/year; other periods use their own period count.
Standard work year
2,080 hours
Based on the common full-time baseline of 40 hours/week x 52 weeks/year.
Bi-weekly vs. semi-monthly
26 vs. 24 paychecks/year
Bi-weekly pays every 2 weeks (26 checks/year); semi-monthly pays twice a month (24 checks/year) - they are not the same schedule.

How the Salary Calculator works

This tool converts a pay rate quoted in one period into its equivalent in every other common pay period. Enter the amount you are paid, how that amount is paid (hourly, daily, weekly, bi-weekly, semi-monthly, monthly, or annually), and your work schedule, and the calculator derives the hourly, weekly, monthly, and annual gross figures.

The formula

The calculator first converts whatever you entered into an annual salary, using the standard period counts:

  • Hourly: annual = hourly rate x hours/week x weeks/year
  • Daily: annual = daily rate x days/week x weeks/year
  • Weekly: annual = weekly pay x weeks/year
  • Bi-weekly: annual = bi-weekly pay x 26 (weeks/year / 2)
  • Semi-monthly: annual = semi-monthly pay x 24
  • Monthly: annual = monthly pay x 12

From that annual figure, every other period is simply annual divided by its own standard count: hourly = annual / (hours/week x weeks/year), weekly = annual / weeks/year, and monthly = annual / 12. All results are gross pay — before federal and state income tax, FICA (Social Security 6.2% + Medicare 1.45%), health insurance premiums, and retirement contributions are withheld.

Worked example

Take a salary of $60,000 per year, worked at 40 hours per week for 52 weeks. Annual pay is already $60,000. Dividing by 2,080 standard hours (40 x 52) gives an hourly rate of about $28.85. Dividing by 52 weeks gives roughly $1,153.85 per week, and dividing by 12 gives $5,000 per month.

Bi-weekly is not semi-monthly

Bi-weekly pay arrives every two weeks, producing 26 paychecks a year — two months of the year get three paychecks instead of two. Semi-monthly pay arrives twice a month on fixed dates (such as the 1st and the 15th), producing exactly 24 paychecks a year. For the same annual salary, a bi-weekly check is smaller than a semi-monthly check because the total is spread across more payments.

Why hours and weeks worked matter

An hourly or daily rate only becomes an annual figure once you know the schedule behind it. The common full-time baseline is 40 hours per week for 52 weeks (2,080 hours per year), but part-time hours, a shorter work week, or unpaid time off all reduce the weeks or hours actually worked and should be entered as such for an accurate conversion.

Frequently Asked Questions

How does the salary calculator convert between pay periods?
It first converts your entered pay amount and period to an annual salary (hourly pay x hours per week x weeks per year, daily pay x days per week x weeks per year, weekly pay x weeks per year, biweekly pay x 26, semi-monthly pay x 24, or monthly pay x 12). It then divides that annual figure by the standard number of periods in a year to produce the hourly, weekly, and monthly equivalents.
What is the difference between bi-weekly and semi-monthly pay?
Bi-weekly means every two weeks, which produces 26 paychecks per year (two months get three paychecks). Semi-monthly means twice a month, on fixed dates such as the 1st and 15th, which produces 24 paychecks per year. The two schedules pay different amounts per check even for the same annual salary.
Why does the calculator ask for hours and weeks worked?
An hourly or daily rate cannot be converted to an annual figure without knowing how many hours or days are worked each week and how many weeks are actually paid in the year. The standard full-time baseline is 40 hours per week for 52 weeks, or 2,080 hours per year, but part-time schedules or unpaid time off change the total and should be entered accordingly.
Does this show take-home pay after taxes?
No. Every figure produced is gross pay before federal and state income tax, FICA (Social Security and Medicare), benefits deductions, and retirement contributions. Actual take-home pay is lower and depends on your tax bracket, filing status, and elected deductions, which this calculator does not model.
