How to use it
Enter your gross hourly rate, the regular hours you work each week and how many days those hours are spread over. Set paid weeks per year to 52 if your holidays are paid, or lower it for unpaid time off. If you regularly work overtime, add the weekly overtime hours and the multiplier your employer pays (1.5 for time and a half, 2 for double time).
The formula
Weekly pay = hourly rate × regular hours + hourly rate × overtime multiplier × overtime hours.
Annual salary = weekly pay × paid weeks per year. Monthly pay is the annual figure divided by 12, biweekly pay is two weeks of pay, and daily pay is weekly pay divided by days worked. The average hourly rate shows what you effectively earn per hour once overtime is blended in.
Worked example
You earn 20 per hour, work 40 regular hours plus 5 overtime hours at 1.5x, and take 2 unpaid weeks off (50 paid weeks). Weekly pay is 20 × 40 + 20 × 1.5 × 5 = 800 + 150 = 950. Annual salary is 950 × 50 = 47,500, monthly pay is 3,958.33, biweekly pay is 1,900 and daily pay over 5 days is 190. Across 45 hours, your average rate is 21.11 per hour.
Practical tips
All figures are gross pay before tax, pension and other deductions, so take-home pay will be lower. A quick rule of thumb: at 40 hours and 52 weeks, double the hourly rate and add three zeros (25 per hour ≈ 50,000 a year, 52,000 exactly). When comparing a salaried job to hourly work, remember that salaried roles often include paid holidays while contract work may not.
Frequently asked questions
How many working hours are in a year?
A full-time 40-hour week over 52 weeks is 2,080 hours. With 2 unpaid weeks off it is 2,000 hours.
Why isn't monthly pay just four weeks of pay?
Most months are longer than four weeks. A year has 52 weeks, so an average month is about 4.33 weeks. Dividing the annual figure by 12 gives the accurate monthly average.
Is this my take-home pay?
No. The results are gross earnings. Taxes and deductions vary by country and personal situation, so they are not included.
What is the difference between biweekly and semi-monthly pay?
Biweekly means every two weeks, which gives 26 paychecks a year. Semi-monthly means twice a month, which gives 24 paychecks. Semi-monthly pay equals the annual salary divided by 24.
