According to Celebrity Net Worth, Joe and his wife, Melissa Gorga, have a combined net worth of around $2 million. The reality star has been open about his career in real estate development, flipping properties by converting them into apartment complexes. On "One on One with Steve Adubato," Gorga talked about his rise as a developer stating, "I made it through hard work, and that's all it takes. Just get up and go to work and give it 100%."

In addition to his career, Gorga has a number of side hustles including his "Grow With Gorga" motivational speaking series. According to its website, Grow With Gorga is "designed to equip attendees with new perspectives, practical tools, and key takeaways that will enable you to enhance your business." In 2019, Gorga penned his own book titled "The Gorga Guide to Success" (via Instagram) which features a how-to guide for "building a real estate empire, maintaining a happy marriage to the love of my life ... and navigating the world of reality TV." 

Finally, Gorga's net worth could be attributed to his involvement with the Bravo series. According to Glossyfied, Gorga pulls in $45,000 a season while his wife is bringing home the bacon with a much larger $600,000 a season.
