Shark Tank mentor Kevin O'Leary recently shared his advice on finances and saving, referring to it as the "best piece of advice" he would give to anyone.

O'Leary Ventures chairman revealed that he would tell his kids "over and over again" to "save it." He said that the money needs to be invested and not "spent." Letting it "compound," the money will result in a gift, in the form of compound interest.

While sharing the advice, Kevin also mentioned that it should be 15% of your paychecks and side hustles. For example, he suggested that if an individual earns an average salary of $68,000, they should save 15% of their income throughout their life. By doing so, the individual would end up being a millionaire by the time they retire.

For those who want to become a millionaire by the age of 65, Kevin O'Leary suggests starting to save:

"If you make $68,000 a year, the average salary, and you do this your entire life, just 15% of your paycheck, they'll end up a millionaire retirement at 65."

He concluded the video by urging everyone not to buy stuff they don't need. Instead of it, he suggested to "invest it" and called it the best piece of advice he could offer anyone.

Fans must know that Kevin often shares financial tips that can help everyone achieve a better and more secure future, financially.

In another post, shared on June 4, 2025, Kevin stated:

"Profit is the loudest applause your business will ever get. If it's silent, you've got a problem."

By that, he meant for entrepreneurs to forget the hype and ignore the noise that comes with it. He stated that if a business does not deliver you profits, then there's a chance that it's just a "hobby."
