Warren Buffett: This is the No. 1 mistake parents make when teaching kids about money

If there’s one person who understands the importance of teaching kids about financial responsibility, it’s Warren Buffett.

Before he became CEO of Berkshire Hathaway, the legendary investor started a handful of small businesses — starting at age six, when he purchased a six-pack of Coke for 25 cents and sold each can for a nickel. He also sold magazines and gum from door to door.

“My dad was my greatest inspiration,” Buffett said in an interview with CNBC back in 2013. “What I learned at an early age from him was to have the right habits early. Savings was an important lesson he taught me.”

When asked what he thinks is the biggest mistake parents make when teaching their kids about money, the billionaire said, “Sometimes parents wait until their kids are in their teens before they start talking about managing money — when they could be starting when their kids are in preschool.”

Yes, you read that right: Preschool. To Buffett’s point, researchers have noted that 80% of our brain growth happens by age 3.

One study from Cambridge University found that kids are already able to grasp basic money concepts between the ages of 3 and 4. And by age 7, basic concepts relating to future financial behaviors will typically have developed.

“Most parents already know how important it is to teach their kids about money and how to manage it properly,” Buffett acknowledged. But there’s a difference between knowing and taking action.

According to a 2018 survey from T. Rowe Price, which gathered responses from 1,014 parents (of children between the ages of 8 to 14) and more than 1,000 young adults (ages 18 to 24), only 4% of parents said they started discussing financial topics with their kids before the age of 5.

Thirty percent of parents started educating their kids about money at age 15 or older, while 14% said they never did at all.

In 2011, Buffett helped launch a children’s animated series called “Secret Millionaire’s Club,” which featured himself as a mentor to a group of students.

There are 26 episodes in the show, and each one tackles a financial lesson, such as how a credit card works or why it’s important to track where you put your money.

“I taught all

Here are a few lessons from the show, along with tips from Buffett on how to teach them to your kids:

The goal of this lesson is to encourage your kids not to give up just because something doesn’t work the first time. The ability to think creatively and outside the box will come in handy when they run into future financial challenges.

Go to an art museum with your kids and discuss the different styles of each painting. Then, invite them to paint something of their own. Have them brainstorm different tools — besides the paintbrush — that can be used (e.g., sponges, cotton swabs, fingers).

Turn your trash into treasure by challenging your kids to come up with new uses for old things around the house (e.g., bottle caps can double as checker pieces, an empty cereal box can be turned into a magazine holder). This will help teach them how to think critically, save money and help the environment all at the same time.

As Ben Franklin once said, “A penny saved is a penny earned.” To help your kids learn to manage their money, it’s important for them to understand the difference between wants and needs.

Give each of your kids two money jars: One for savings and one for spending. Each time they receive money (e.g., as a gift, for allowance, for walking the neighbor’s dog), talk to them about how they wish to split the money between savings and spending.

Have your kids make a list or create a collage from magazine photos of five to 10 things they’d like to purchase. Then, go through each item with them and mark whether it’s a want or a need (e.g., a new toy is a want, while a new backpack is a need.)

We’ve all been guilty of paying more money for a cool brand of shoes or gadget when we could have gotten a similar item that was just as good for a lesser price.

The idea behind this lesson is to help kids understand the different ways advertisers get us to buy their services or products, as well as how to tell what is and what isn’t worth paying for.

Make a list of items you need at the supermarket, and then check flyers, newspapers and websites with your kids for items on the list that may be on sale. Compare those prices and see which store offers the best deal for a specific product.

Pick up a magazine with your kids and choose an ad to evaluate. Ask them: What’s being sold? What message is the ad trying to get across? What catches their attention in the ad? How does the ad make them feel? How is it trying to persuade them to buy the product?

The key to making smart decisions is to think about how different choices can impact future outcomes.

Buffett suggests modeling good decision-making skills and talking to your kids about your decisions as you make them, as well as any resulting domino effect they could have. For example: “We want to buy a new TV, but our AC is broken and we need to save money to get it fixed. If we don’t, it will be too hot in the house when summer comes. Once the AC is repaired, we can think about buying the TV.”

Get your kids into the habit of making good decisions about how to save money. Maybe there’s a DVD they want to buy. Ask them whether they really need it or if they can rent the movie from the library.

Instilling healthy financial habits in your kids is one of the most important things you can do to help ensure they have a successful future.

“It’s never too early,” Buffett said in a Q&A with Yahoo Finance in 2013. “Whether it’s teaching kids the value of a dollar, the difference between needs and wants or the value of saving — these are all concepts that kids encounter at a very early age, so it’s best to help them to understand it.”
