Mark Cuban is the billionaire entrepreneur best known for his former appearances on the hit TV show Shark Tank. However, he also frequently gives advice and tips to help people improve their financial fitness. If you're someone who wants to make a solid retirement plan and enjoy your golden years someday, here are a few pieces of his advice.

Interestingly, Cuban is known for not being like most billionaires. He gives straightforward, practical advice that is within reach for many people. He's not a proponent of expensive investments or of going into high-interest debt.

Many successful investors eventually reach the same moment. The saving is done, the portfolio is built, and the question quietly changes from how much can I grow this to how much can I take out? Get that second question wrong and decades of good investing can come apart in a handful of years.

Live well below your means and avoid lifestyle creep

One tip that Cuban repeats in many interviews is to avoid lifestyle inflation. Even though Mark Cuban is a billionaire, he is not someone who increased his lifestyle every time he sold a company or had a large financial accomplishment.

Rather, his money habits are built on discipline and simplicity, and that's what he encourages other people to do as well. In fact, you don't need insider access to follow his advice. For example, Cuban is known for maintaining many of the frugal habits he has always had. He's not interested in fancy watches, and he doesn't have a chauffeur. His priorities are his family and his businesses.

Cuban encourages others to live below their means and avoid lifestyle creep if they, too, want to achieve financial freedom one day. This is especially important for people nearing retirement, since most retirees live on a smaller, fixed income.

Eliminate high-interest debt as soon as possible

Cuban frames paying off debt as one of the best investments people can make. He explains that because credit cards have sky-high interest rates, people can earn a guaranteed 20-plus percent return by paying them off.

This advice can help retirees improve their cash flow and reduce stress. Carrying high-interest debt into retirement can mean large minimum payments, which reduce the available income retirees may need for their living expenses.

Retirees have to consider numerous costs as they age, including rising grocery prices, housing maintenance, and expensive health care costs. Eliminating credit card debt can help retirees improve their finances and afford their bills.

Always keep a large cash cushion equal to six months

Many financial experts recommend maintaining an emergency fund, but Cuban believes people should have emergency savings equal to six months of expenses. Having this type of money set aside is useful in emergencies. However, he also says it can help people take advantage of different opportunities as they arise.

A cash buffer can also help retirees pay for their bills during a down market where they may not want to withdraw from their retirement accounts. Withdrawing money during a market downturn can negatively impact a retiree's nest egg well into the future.

Most people spend their entire working lives focusing on one thing: growing a pile of money. Then they retire and discover the skill they actually need is close to the opposite. Turning that pile into steady income, year after year, through good markets and bad, without ever running out. It may be the least discussed and most consequential transition in personal finance, and plenty of otherwise careful investors walk into it with no real plan.

Invest simply and cheaply, avoid complex products

There are many different types of investments available to people. These include stocks, bonds, mutual funds, real estate, and even cryptocurrency. However, Cuban is a proponent of investing simply and cheaply.

He says that many investments come with high fees, and those fees can reduce the amount of investment returns people get over time. Instead, he recommends that average investors buy index funds instead. Index funds usually have very low fees, unlike actively managed mutual funds.

Don't invest money into anything you don't fully understand

Additionally, another one of Cuban's investing tips is to avoid investing in any business that you can't clearly explain.

Many people may come across investment opportunities or even family members who want them to invest in a business. However, Cuban says to avoid this and keep your investing strategy simple. So, even if you read about the latest stock pick or hear about a company that is about to make it big, Cuban still recommends index funds because of their diversity.

Protect what you already have through disciplined habits

Most of Cuban's advice comes down to developing disciplined habits. He says that saving money isn't enough. Rather, people should learn how to invest their money. Doing this consistently over time can allow compound interest to work, helping retirees achieve financial security during their golden years.

For many people, earning money is straightforward, but managing spending can be a challenge. Following Cuban's advice and becoming a disciplined spender and investor can help people retire on time with enough saved to cover their expenses.

Think for yourself and always ask questions

Finally, one of Cuban's best pieces of advice is to always think for yourself. He wants people to ask questions about their personal finances and investments, not choose assets based on a financial advisor's opinions.

He says that finances can be complex, and asking questions can make money decisions much easier to understand and navigate.

Bottom line

Mark Cuban wants to help people prepare themselves financially for retirement, and his advice is straightforward and simple. Ultimately, he encourages people to avoid high-interest debt, complex investments, and lifestyle inflation.

Additionally, he recommends building an emergency fund and becoming disciplined with saving and investing for your future.
