How do I calculate my daily rate if I know my monthly salary?

Divide your monthly salary by the number of working days in the month. For an average, use 21.75 working days. For a specific month, use the actual count of weekdays minus any public holidays.

Does February always have 20 working days?

In a common year, February has 28 days and exactly 20 weekdays. In a leap year, it has 29 days and can have 20 or 21 weekdays, depending on the starting day.

What is the maximum number of working days in a month?

A 31-day month can have up to 23 weekdays. This happens when the month starts on a Monday, Tuesday, or Wednesday.

Should I use 21.75 for payroll even if a month has many holidays?

It depends on your payroll policy. Many employers use 21.75 as a standard average year-round, but some adjust for actual workdays each month. Check your company's practice.

How Many Working Days Are in a Month?

How many working days are in a month? It depends on the month and the year. Most months land between 20 and 23 business days. A flat 21.75 is the payroll benchmark, but actual counts shift as weekends and public holidays move around the calendar. Use the exact count when you run payroll or schedule a project deadline. Use the average for quick estimates and daily-rate calculations.

Average Working Days Per Month

Payroll systems and budget templates rarely count each month from scratch. A standard year holds 260 to 262 weekdays, Monday to Friday. Divide the typical 261 by 12 and you get 21.75 workdays per month. That figure is the industry default for turning a monthly salary into a daily rate: take the monthly pay, divide by 21.75. Remember that the 21.75 benchmark ignores public holidays. Those vary by country and will shrink the real number of workdays in any given month.

Monthly Range of Weekdays

A single month can deliver as few as 20 business days or as many as 23. The exact number turns on the month’s length and the day of the week it starts.

31-day months: 21, 22, or 23 weekdays.
30-day months: 20, 21, or 22 weekdays.
February in a common year: always exactly 20 weekdays.
February in a leap year: 20 weekdays if it starts on a Saturday or Sunday, 21 otherwise.

Because the starting day shifts each year, the same month can land on a different weekday count from one year to the next. Check a calendar before you commit a deadline.

Why 21.75 Working Days is Used

Payroll and Daily Rate Calculations

Employers lean on 21.75 to convert a monthly salary into a daily rate. Divide a monthly salary by 21.75 and you get a daily rate. The formula smooths out the gap between a 20-workday month and a 23-workday month. It gives you a single, defensible number for overtime, leave deductions, and budgeting.

Limitations of the Average

The 21.75 average assumes zero public holidays. In countries with several national holidays, the actual workdays this month will be lower. For precise payroll, count the real weekdays in the month and subtract every holiday that falls on a Monday through Friday. Do not let the average overstate your available working time.

How to Count Workdays for a Specific Month

To lock down the exact number of business days in a month for your location, work through these steps:

List every day of the month.
Mark each Monday through Friday as a weekday.
Count the marked days.
Subtract any public holidays that land on those weekdays.

A 31-day month that starts on a Wednesday gives you 23 weekdays. If one public holiday falls on a Wednesday that month, the count drops to 22 working days. That is your precise figure for payroll or a project timeline.

Common Month Lengths and Their Weekday Ranges

Here is how the weekday count breaks down by month length:

31-day months (January, March, May, July, August, October, December): 21, 22, or 23 weekdays. The highest count, 23, happens when the month starts on a Monday, Tuesday, or Wednesday. The lowest, 21, occurs when it starts on a Friday or Saturday.
30-day months (April, June, September, November): 20, 21, or 22 weekdays. Starting on a Saturday gives 20; starting on a Monday gives 22.
February in a common year: Exactly 20 weekdays. Twenty-eight days is four full weeks.
February in a leap year: 29 days. If the month starts on a Sunday, expect 20 weekdays; otherwise, expect 21.

These ranges let you estimate the workdays this month without counting every day on the calendar.

Adjusting for Public Holidays

Public holidays cut into the working-day count. They differ by country, region, and employer. A national holiday on a Monday in a month that would otherwise have 22 weekdays drops the count to 21. Some months carry several holidays. When you calculate a daily rate from a monthly salary, you can use the actual workdays after holidays for that specific month, or stick with the 21.75 average for consistency. The choice depends on your payroll policy. Either way, subtract the holidays before you finalise a schedule.

Using the Average for Planning

For project timelines and resource allocation, 21.75 working days per month is a solid estimate. It absorbs the fact that some months run long on business days and others run short. Need a tighter figure for a specific period? Count the actual weekdays and subtract holidays. For a fast reference, lock in these two facts: February in a common year always has 20 business days, and most other months sit between 21 and 23.
