6 things people who are good with money always splurge on

Get your groceries delivered instead of going to the store. Send your laundry out or hire a house cleaner. If you could theoretically spend that time at work and earn more than you spend on those services, you come out ahead, Palmer said.

A common theme in Palmer's advice is to splurge on things that give you more time to enjoy your life. "To me, money is all about giving you the life that you want, and that usually means spending time in the ways that make you happy," she said. "The best thing you can do with your money is to use it to free up time."

Premium travel reward cards can come with hefty fees — the Chase Sapphire Reserve, for example, costs $450 per year. But for some people, the fee can be worth it.

"If you spend a lot of money on travel and want to redeem a lot of rewards on travel," Palmer said, these cards offer a better value than mileage cards with no annual fees.

It all depends on how much you travel and how much you charge to the card, but Palmer noted that you could earn thousands of dollars in miles or points with a premium rewards card, which makes the annual fee a smart splurge.

When it comes to cooking tools, Palmer thinks a few expensive purchases can really pay off. "I always splurge on this," she said. "You can save so much money by cooking at home."

Add the health benefits of home cooked meals over restaurant food, and a splurge that makes cooking fun is a good investment.

Palmer's go-to kitchen indulgence is a Nespresso coffee machine. She said that she has more than recouped the cost of the appliance by forgoing $4 lattes. "I think it saves time too," she said, noting that, in the time it takes to get to the coffee shop, wait in line, and get her order, she could be sitting in her kitchen enjoying a good cup of homemade coffee made just the way she likes it.

Palmer's personal favorite splurge is her monthly membership is Barre 3. "It feels good and it gives me more energy," she said of the streaming workouts. An experience that improves your health and quality of life can be a good target for a splurge.

"A great splurge to one person is a waste of money to someone else," Palmer said.

If you love photography, a camera is a great investment. If blurry selfies are good enough for you, the camera in your phone is all you need.

"It depends so much on what gives you pleasure, and that's the best splurge for you," she said.
