I Asked ChatGPT What Money Mistake Repeats Every Year for Most People — Here's How To Stop

As the midpoint of the year has come and gone, many people like to reflect on their finances. In addition to thinking about what they’ve saved and how they’ll invest, they may also want to ponder the common mistake that keeps them from achieving their financial goals.

But what is the mistake that even the best-intentioned people make every year?

I figured I’d ask ChatGPT. While you’ll want to work with a human financial advisor for advice tailored to your situation, I wanted a more general take from the AI. According to ChatGPT, one common financial mistake can repeatedly derail progress toward your goals — but it’s also avoidable.

ChatGPT gave me a very direct answer to my question: "The financial mistake most people repeat every year is treating predictable expenses like unexpected emergencies," it wrote.

The AI explained that while many households know certain expenses are coming, they don’t save for them.

Think these expenses must be extreme? Think again. Here’s what the AI said people often forget to save for:

  • Summer vacations

  • Back-to-school shopping

  • Holiday gifts

  • Annual insurance premiums

  • Property taxes

  • Car registrations and maintenance

Since people haven’t saved for these regular obligations, they often end up relying on credit cards or draining their emergency savings.

Even people who budget regularly are vulnerable to this mistake.

"People often budget for monthly bills but not for irregular ones," ChatGPT wrote. "The budget may leave out expenses that occur only once or twice a year. When those bills arrive, they feel like surprises even though they're entirely predictable."

That can create cash-flow problems and make it harder to stay on track financially.

So what can you do to remedy this error? The AI had some suggestions.

ChatGPT suggested listing every nonmonthly expense you can think of. Think of anything that can creep up on you:

  • Car insurance

  • Holiday gifts

  • Vacations

  • School supplies

  • Membership renewals

  • Home maintenance

  • Pet expenses

  • Taxes and fees

"Estimate the cost and write down the month each expense is due," ChatGPT wrote.

If you don’t like scrambling for $600 to pay a car insurance premium that comes due in December, ChatGPT suggested saving $50 each month in a sinking fund. With a sinking fund, you set aside small, manageable amounts of money for a specific, planned expense.

Sinking funds can cover some of the following irregular expenses:

  • Holidays

  • Travel

  • Car maintenance and repairs

  • Home maintenance

  • Medical expenses

Though ChatGPT didn’t say this, I’ll add my own perspective: Consider keeping your sinking fund in a high-yield savings account.

ChatGPT offered relatively simple advice that seemed easy to implement: Set up an automatic transfer every payday into a dedicated savings account.

"Even $20 to $50 per paycheck adds up over time," the AI wrote.

What are you doing midsummer and at the end of the year? Sure, you could say you're hanging out at the pool and ringing in the new year, but you may also want to conduct a budget review, according to ChatGPT.

"A midyear and year-end budget review helps you adjust for rising costs and identify categories where you're consistently overspending," the AI wrote.

ChatGPT also said you should separate your emergency fund from planned expenses — and it could not have been clearer.

"Your emergency fund should cover genuine surprises, such as job loss or an unexpected medical bill — not expenses you knew were coming," it said.

Again, the AI didn’t say this, but I’ll weigh in with some human advice: Strongly consider keeping your emergency fund in a high-yield savings account.

ChatGPT was clear that breaking this habit can reduce your credit card debt, lower your financial stress, protect your emergency fund and make large purchases feel more manageable.

"For many people, this single change is more effective than trying to cut out small discretionary purchases because it addresses the recurring cash-flow problems that often lead to debt," ChatGPT said.
