7 things people who are good with money never buy

When it comes to leasing, Khalfani-Cox says that someone who's good with money will likely turn the other way. "They're not going to say, 'oh, let me lease this $50,000 car, and then next year let me lease another one,'" she says.

Leases will still involve down payments, and though the monthly payment and up-front payments may be lower, you'll never own anything like you could with a loan. Though a lease might seem like a way to dodge debt in the short term, those who are good with money will see it in a different light.

"If you're motivated by the lowest long-term cost, buying and keeping your cars longer will make more financial sense," Alain Nana-Sinkam, the vice president of strategic initiatives at TrueCar, previously told Business Insider's Tanza Loudenback.

Those who are good with money are likely to be less caught up in needing the latest and greatest, meaning a lease won't really be the best option for them.

Those who are good with money aren't looking to spend more than they can afford on a home, and they know that the best piece of real estate is the one they can afford.

Business Insider contributor Holly Johnson saved aggressively to pay off her home by age 40, and travels for multiple months of the year by spending frugally and leveraging credit card benefits.

And when it came to buying a house, she and her husband bought a significantly smaller house than they could have to pursue early retirement and living mortgage-free. "Housing affordability calculators have always told us we could spend double, triple, or more than we did on a home," writes Johnson. "But we have always ignored them and forged our own path."

Instead of buying a large, expensive house, they opted to spend on experiences. If they'd bought a larger house, she writes, "we would have a lot less money to save and invest each month toward early retirement. We would also have to drastically curb our annual travel budget."

Whether it's a $2,000 purchase or a $20 purchase, those who are good with money won't pay interest on their purchases.

Carrying a balance on your credit card means you'll be charge interest every month, and it won't be cheap, either — many credit cards will charge interest rates of 25% or more.

Business Insider writer Elizabeth Aldrich racked up $10,000 worth of debt in her 20s. But, since then, she's learned from her past and has become good with money, paying it all off in three years and building a $20,000 emergency fund in six months.

As she looked back on the money mistakes that got her into debt, she cites carrying a credit card balance as one of the biggest issues. "Every month I would run up a balance on my credit card and then pay off what I could by the end of the month," she writes. She also writes that this habit caused her to "spend thousands of dollars on credit card interest in my 20s."

Now, she never spends money on interest.

Those who are good with money are "less interested in brand names or tags and labels," says Khalfani-Cox. And it seems that those with wealth are starting to take this cue from those who are good with money.

As Business Insider's Hillary Hoffower reports, "showing off wealth is no longer the way to signify having wealth. In the US particularly, the top 1% have been spending less on material goods since 2007."

Instead of material items, many wealthy people these days are opting to spend on privacy, exclusive wellness and fitness routines, and investing in education instead of buying designer items.

Those who are good with money aren't filling their closets with fast fashion clothing and buying an abundance of cheap things that will break. Instead, they'd rather put money into items that will last.

"They're more concerned with quality as opposed to quantity," says Khalfani-Cox. She continues: "I think people who are good with money are often not afraid to go against the grain and to actively unplug from consumerism."

Anyone who's planned a wedding knows just how costly they can be. But those who are good with money aren't planning to spend lots of money on their ceremony.

Nathan Clarke of The Millionaire Dojo used aggressive savings techniques and investments to sock away over $100,000 in savings by age 25, and he has hopes of becoming financially independent and is pursuing his goals of becoming a millionaire.

For him and his now-wife, one of the things that helped him to reach $100,000 in savings was a low-cost wedding. They spent just $10,000 on the big day, and saved aggressively instead of spending on the wedding.

"Really, all we paid for was all the decorations, food and a little bit for the reception venue," writes Clarke. "I don't understand why people think they have to spend $50k on a wedding. I'd rather travel the world for a year with $50k than spend it on one day."
