Renting and Buying property
Landlords want to ensure you have sufficient earnings to meet your monthly rent implications. And accomplish that, they usually look at your gross income to figure out if you can reasonably cover the rent and utilities. Lenders will also want to know if you can make the monthly payments towards your mortgage.
Loan qualification
Finally, you’ll need to provide proof of your identity and ability to repay the personal loan you’re applying for on time. Your gross income determines whether you meet the thresholds qualifying you as a loan recipient. Typically, lenders won’t let you borrow more than 28% of your gross monthly income.
Calculating Your Gross Monthly Income for an annual salary
Calculating your gross monthly income is easy if you are paid an annual salary. Take your annual wages and divide them by 12.
For example, at her digital marketer job, Nancy is paid an annual salary of $48,000. To calculate her gross monthly income, divide her annual wage by 12. Nancy will have a monthly gross income of $48,000/12=$4,000
Calculating Your Gross Monthly Income for weekly pay
For those that receive a weekly income, take it and multiply it by 52 and divide it by 12. If your weekly pay varies, then use your average weekly income instead.
To get the best weekly average income, calculate it over as many weeks as possible but not more than 52 weeks / 1 year. Once you have it, repeat the process above.
For example,
Jane receives a weekly wage of £500 every week from her job as a customer service consultant. To calculate her gross monthly wage, multiply her weekly salary of £500 by 52 and divide by 12 to give £500 * 52 / 12 = £2,166.67.
In another example,
Steve receives a weekly wage of £230 as an assembly line operator but sometimes has to work overtime and is reimbursed for it. In the last four weeks, Steve has received £120 for overtime worked.
To calculate Jack’s gross monthly wage, multiply his weekly wages of £230 by 52 and divide by 12 to give £215 * 52 / 12 = £996.67 without accounting for overtime. Jack earned £120 in total from the last four weeks of overtime, so his gross monthly wage from overtime alone is £120 divided by 4, multiplied by 52, and divided by 12. Jack’s gross monthly wage from overtime alone is £120 / 4 * 52 / 12 = £130. Jack’s gross monthly, including his weekly wages and overtime, is, therefore, £996.67 + £130 = £1,126.67.
Take your hourly rate multiplied by the number of hours worked per week if you earn weekly. Then multiply that by 52 and divide by 12 to get your gross monthly income.
