Work & Pay

Salary Calculator

Convert any pay rate into every other one — hourly to annual, salary to hourly, and everything in between.

Enter any pay amount and see it converted to every other period at once.

Exact calculation. Given your inputs, this is the answer — no estimation involved.

How this calculator works

Everything is converted to an annual figure first, then back out to each period. That single hub is what keeps the conversions consistent: hourly to monthly gives exactly the same answer as hourly to annual to monthly.

Two conventions matter, and both are yours to set. Weeks worked per year drives the hourly, daily and weekly figures — lower it below 52 to model unpaid time off. Paycheck counts stay fixed by the calendar, because there are always 26 biweekly and 24 semi-monthly paychecks in a year regardless of how many weeks you worked.

The calculator never uses the "one month is four weeks" shortcut. Four weeks is 28 days; the average month is 30.4. That shortcut understates monthly pay by about 8%, and it is the most common error in salary conversions.

The formula

Exactly what happens to your numbers, step by step.

From hourly to annual

annual = hourly rate × hours per week × weeks worked per year

From annual to everything else

monthly     = annual ÷ 12
semi-monthly = annual ÷ 24
biweekly     = annual ÷ 26
weekly       = annual ÷ weeks worked
hourly       = annual ÷ (hours per week × weeks worked)

Monthly, semi-monthly and biweekly use calendar counts; weekly and hourly use the weeks you actually worked.

A worked example

Converting $25 an hour, working 40 hours a week for all 52 weeks.

What you enter

Amount: $25.00 per hour
Hours per week: 40
Weeks per year: 52

Step by step

Annual: 25 × 40 × 52 = $52,000
Monthly: 52,000 ÷ 12 = $4,333.33
Every two weeks: 52,000 ÷ 26 = $2,000.00
Weekly: 52,000 ÷ 52 = $1,000.00

$25.00 an hour is $52,000 a year

Note the monthly figure: $4,333, not the $4,000 that "40 hours × 4 weeks" would give. That $333 a month is the error the four-week shortcut introduces.

Assumptions

Every result here rests on these. Change your inputs and the result changes with them.

Every week has the same hours. Overtime is not included — use the Overtime Calculator for that.
Weeks worked per year defaults to 52, which assumes paid time off rather than unpaid.
Paycheck frequencies use calendar counts: 26 biweekly, 24 semi-monthly, 12 monthly.
All figures are gross, before tax and deductions.

What this cannot tell you

It converts gross pay only. Nothing here accounts for tax, retirement contributions or benefit deductions, so it is not what lands in your account — the Paycheck Calculator handles that.
It assumes you are paid for every hour worked. Salaried exempt roles routinely involve unpaid extra hours, which lowers the real hourly rate below what this shows.
The 2,080-hour year is a convention, not a measurement. It assumes 40 hours across 52 weeks with no unpaid leave; a year actually contains 2,088 hours on average, and paid time off changes the figure again.
It does not value benefits. Health insurance, an employer retirement match and paid leave can be worth a substantial fraction of salary, and two jobs with identical pay can differ considerably in what they are worth.

Questions people ask

How do I convert an hourly rate to a salary?

Multiply your hourly rate by the hours you work in a week, then by the number of weeks you are paid for in a year. At 40 hours over 52 weeks, the shorthand is to multiply the hourly rate by 2,080.

Why is monthly pay not four weekly paychecks?

Because a month is longer than four weeks. There are 52 weeks in a year but only 12 months, so a month averages about 4.33 weeks. Multiplying weekly pay by four understates the month by roughly 8%.

How should I handle unpaid time off?

Lower the "paid weeks a year" figure. Two unpaid weeks means 50, which reduces the annual total for an hourly worker. A salaried employee is normally paid for all 52 weeks, so leave it at 52.

How do I convert a weekly salary to a yearly salary?

Multiply the weekly pay by 52, the number of weeks in a year. $1,000 a week is $52,000 a year, which is $25 an hour at 40 hours a week. If you are not paid for every week of the year, because of unpaid time off or seasonal work, use the number of weeks you are actually paid instead. The calculator lets you change it.
