How to Calculate Salary Per Month

by Kristen May ; Updated September 11, 2015

Jobs rarely pay by the month, but most of your bills such as a mortgage, credit card bills and utilities are due every month. Calculating your monthly salary is an important step in managing your household cash flow from one month to the next. Whether you know your hourly, weekly, bi-weekly or annual pay, you can convert this amount into a monthly salary. Once you know your monthly salary, you can use this amount to make a budget or spending plan in which you spend no more than the amount you earn each month.

Look up exactly how much you make per hour, week, two weeks or year. You can look this up on your most recent paycheck, check your employment contract, or ask your employer. For these calculations, you want the pre-tax amount, which is your gross salary.

Multiply your hourly pay by the number of hours you work per week to convert it into a weekly salary. If your weekly hours fluctuate, estimate the average number of hours per week for this calculation. For example, if you work 40 hours per week at $13.72 per hour, you earn $549.60 per week.

Multiply your weekly pay by 52 to find your annual salary. If you are paid bi-weekly, multiply this bi-weekly amount by 26 to find your annual salary. In the above example, $549.60 times 52 gives you $28,579.20 per year.

Divide your annual salary by 12 to calculate your salary per month. For example, divide $28,579.20 by 12 to calculate a salary of $2,381.60 per month.
