There are several reasons why you may need to calculate your monthly income. For example, it enables you to have a better understanding of your finances, plan ahead, and make informed decisions. This is simple if you earn a monthly salary because you can see your gross monthly income on your pay stubs. Even then, you may need to calculate your income to ensure that there are no errors. If you receive weekly wages, you may also need to calculate your monthly salary, gross, and others. This article explains how to calculate your monthly income from your hourly, weekly, or biweekly paycheck. You will also learn how to calculate your weekly income based on your monthly, annual salary, and after-tax income.

What to Include in Gross Income?

Gross income is the total amount of money earned throughout a given period. This includes salary, bonus, commissions, side hustles, freelance earnings, or any other type of income, including Social Security. Depending on the circumstances, this may also include income from dividend payments, interest payments, and capital gains.

You will not need to account for taxes when determining your gross income. Taxes are irrelevant to the calculation because gross income is purely a pre-tax amount.

The Importance of Knowing your Gross Monthly Income

If you’re applying for a home or car loan, or if you’re trying to create a budget, you need to know how much money comes in each month. Most lenders will want to know how much you make to determine whether you’ll be a reliable borrower.

Knowing your gross monthly income can also assist you in determining how much to set aside for retirement. Knowing where you stand in terms of gross income will help you make an informed decision about how much to put into your retirement account each month.

The importance of your net income cannot be overstated. Net income can be thought of as the “spendable” cash that flows into your checking or savings account each month. Net income is also useful in creating a monthly budget because it will cover all of your regular after-tax expenses, both fixed and discretionary.

Sadly, if you are quoted a salary of $75,000, you will not receive that amount in cash. Knowing your net income will assist you in creating a more stable budget and staying on top of your finances because a significant portion of your income is dedicated to taxes and fixed deductions.

How to Calculate Monthly Income

There are several reasons why it is necessary to calculate and understand your gross monthly income. As an employee, your gross monthly income is the total amount of money your employer pays you in a month before any deductions such as taxes are made. This is the first amount on your pay stub that appears before your net income is determined.

Simply divide your gross annual salary by 12 to calculate your gross monthly pay. Calculate your gross annual income if you earn money every week by multiplying your gross weekly income by 52 and dividing the result by 12. You must first calculate your weekly wage if you earn an hourly wage before calculating your gross monthly income.

For instance;

If John makes $20 per hour and works 10 hours per day, his weekly pay is $20 x 10 x 7 = $1400. Multiply his weekly pay by 52 and divide by 12 to calculate his gross monthly income. Therefore, John’s gross monthly income is $1400 x 52/12= $6,060.67.  If you receive multiple incomes each month, your gross monthly income is the total of those incomes. Use a labor cost calculator instead.

Calculate Monthly Income after tax

Simply subtract all taxes from gross income to calculate monthly after-tax income. Assume a $50,000 annual salary and 12% tax. It would result in $6,000 in tax per year. As a result, after-tax income for this person would be $44,000.

The same formula is used to calculate after-tax income for corporations, except that gross income is replaced with net income. Corporations’ net income will be disclosed on the income statement when calculating year-end financials. Total revenue minus expenses and losses equal net income.

The corporation will determine after-tax income after calculating net income and deducting all applicable taxes. In general, corporations want to show higher after-tax income because it shows profitability.

Real-World Example

Let’s assume a San Francisco resident has an annual salary of $70,000. Individuals in California must pay federal income taxes of 14.13% and state income taxes of 5.43%. Employees are required to pay 8.65% in federal insurance contributions (FICA), which go toward services like social security, Medicare, and unemployment insurance.

To calculate the individual’s monthly after-tax income, we must first determine their total taxes by adding their tax rates:

Total Taxes = 14.13% + 5.43% + 8.65% = 28.21%

$75,000 x 0.2821 = $21,157.50
Therefore, the individual’s total annual taxes are $21,157.50.
We can now compute their after-tax income:

Gross income – Taxes = After-Tax Income

$75,000 – $21,157.50 = $53,842.50 is your after-tax income.

The individual’s yearly income after taxes is therefore $53,842.50.

Calculate Monthly Income from hourly

The calculation is a little more complicated for hourly employees. To calculate your yearly salary, first, multiply your hourly wage by the number of hours you work each week, then multiply the total by 52. Now that you know your annual gross income, divide it by 12 to calculate your monthly payment.

(Note: If your hours vary from week to week, use your best estimate of the average number of hours you work.)

For instance, if your hourly rate is $15 and you work 40 hours a week, your weekly gross pay is $600. The result is a yearly gross income of $31,200 when multiplied by 52. Last but not least, dividing by 12 yields a monthly gross income of $2,600.

You can generally add any special circumstances, such as a certain number of overtime hours per month or a recurring bonus or commission, to your gross monthly income.

The most common method is to divide the amount of overtime pay (or bonus or commission) you’ve received over the past year by 12. The gross monthly income you calculated from your base pay would then be increased by this amount.

Calculate Monthly Income from the Weekly Paycheck

You can determine your monthly income with simple equations, depending on how many pay periods there are in a year. Your weekly paycheck can also be used to calculate your monthly income.

Contrary to popular belief, you cannot simply divide your monthly salary by four to obtain an accurate number. Instead, multiply your weekly paycheck by 52 and divide the result by 12 to calculate your monthly income.

Example Calculation

If Simon earns $250 per week as a storekeeper, the following is how he can calculate his monthly income:

$250 X 52/12= $1,083.33.
If Simon receives a $250 weekly paycheck, his monthly income is $1,083.33.

Calculate Weekly Income from Monthly Salary

If you ever need to calculate your weekly wage from your monthly income, simply multiply your monthly gross pay by 12 and divide the result by 52. Your gross annual income is determined by multiplying it by 12 first, and your weekly wage is determined by dividing it by 52.

Example Calculation

As a technician, James makes $1000 per month. James’ weekly income can be calculated as follows: $1000 x 12/52= $230.769. If James has a $1000 monthly income, his weekly income would be $230.769.

Calculate Monthly Income from the Biweekly Paycheck

Gross and net are the two types of monthly payments to be aware of. Each is useful in different circumstances. Most lenders calculate your debt-to-income ratio when you apply for a loan using your gross monthly income (DTI). However, many people find it easier to budget based on net or take-home pay. A budget planner app can assist you in determining the best approach for your specific situation.

As previously stated, the formula for gross monthly income is: if you are paid biweekly (every two weeks)

(Gross pay amount × 26) ÷ 12

Hourly workers can also use this formula if they work a consistent number of hours per week:

(Hourly salary × weekly hours worked × 52) ÷ 12

Substitute your actual paycheck for the gross amount in the first formula to calculate your net monthly pay.

To calculate gross monthly income from a biweekly paycheck, multiply the gross amount by 26, then divide by 12. (Do not use this formula if you are paid twice a month on the same dates rather than the same days of the week.) In the same calculation, replace the gross amount with your net or take-home pay to determine your monthly net pay.

Calculate Monthly Income from Annual Salary

The calculation is fairly simple if you receive an annual salary. Gross income, which is how an annual salary is typically expressed, refers to the total amount you earn before taxes and other deductions. Simply divide the total amount of money (salary) you are paid for the year by 12.

For example, if you earn a $75,000 annual salary, the formula calculates your monthly gross income to be $6,250.
It’s also useful to know your biweekly gross income because many people are paid twice a month. Divide your monthly gross income by two to arrive at this figure.

Continuing with the previous example, you would divide $6,250 by 2 to get your biweekly gross income of $3,125.

What is the Total Monthly Income?

Simply put, your gross monthly income is the total amount of money you make each month from all sources. It combines your gross monthly salary or gross pay from your employer before tax or any other deductions made by the employer, as well as any other types of income you may have.

How to Calculate Income?

To begin, calculate your weekly earnings by multiplying your hourly rate by the number of hours you work per week. Then divide the result by 52, the number of weeks in a year. To determine your monthly gross income, divide the result by 12.

How do you Calculate Monthly Income from a Biweekly Paycheck?

If a client is paid biweekly (every two weeks), add the biweekly amounts (after deducting cents from each paycheck), divide by 2, and multiply by 2.15. If the month includes a periodic extra check (i.e., three checks received), divide by three, subtract cents, and multiply by 2.15.

How do you Calculate Monthly Income to Yearly?

Simply multiply your monthly payment by 12 to determine your yearly salary from your monthly payment. Divide your annual salary by 12 to determine your monthly payments.


When creating a budget and calculating tax liabilities, retirement contributions, and other deductions, it is essential to know your gross monthly income. If you ever apply for a loan or fill out paperwork to rent an apartment, your gross monthly income will be considered.

Last but not least, it’s critical to understand the distinction between gross and net monthly income. Your net monthly income is the amount you can expect to receive in your bank account each month, whereas your gross monthly income is the total amount of money you earn. These amounts are vastly different, but they are easily mixed up.
