Salary Converter

Converts a pay amount quoted per hour, day, week, two weeks, month or year into all the other periods, using the hours per week, days per week and paid weeks per year you specify.

When to use

You need to compare an hourly wage with an annual salary, or see what a salary works out to per month, per week or per hour before tax.

Do not use when: You need take-home pay after income tax and deductions, or overtime at a premium rate (multiply the extra hours by the premium separately).

Formula

annual = amount × periods per year, where periods per year = hours_per_week × weeks_per_year (hourly), days_per_week × weeks_per_year (daily), weeks_per_year (weekly), weeks_per_year / 2 (biweekly), 12 (monthly) or 1 (annual); every other period = annual / its periods per year

Gross (pre-tax) conversion with a 52-week, 2,080-hour year by default; the US federal government uses a 2,087-hour divisor for its own hourly rates, which changes the hourly figure by about 0.3 %.

FAQ

Why is monthly not weekly × 4?

A year has 52 weeks but 12 months, so a month averages 4.33 weeks. Monthly pay is annual / 12, which is weekly × 52 / 12.

How do I handle unpaid vacation?

Reduce weeks_per_year: an hourly worker with 2 unpaid weeks off earns 50 weeks × hours_per_week × rate per year.
