6 Money Rules That Worked 20 Years Ago — and Fail Now

6 Money Rules That Worked 20 Years Ago — and Fail Now

For years, personal finance advice was built around simple rules designed for a more stable economy. Americans have been taught to follow some key financial rules that made sense for a long time. But higher living costs, longer careers, shifting job patterns and mounting financial tradeoffs have made many of those once-reliable rules harder to follow and, in some cases, financially risky.

Experts explained which money rules fail now and what to do instead.

1. Save 10% of Your Income

For decades, saving 10% of your income was considered a gold-standard rule of thumb. But that advice was shaped by a very different economic reality, one with lower healthcare costs, shorter retirements and more stable career paths. Today, “cost of living is on the rise and wages are stagnant,” said Ashley Morgan, a debt and bankruptcy lawyer at Ashley F Morgan Law, PC. This means that even when being conservative with budgets, people have to spend more money to meet a minimal standard of living, she stressed.

Robin Lovely, a CFP, retirement planner and founder at The Women’s Advisory Group, works with many clients — often women — who are dealing with divorce, caregiving or career transitions. “The old guideline of saving 10% of your income doesn’t reflect their realities today,” she said. She advises her clients to aim closer to 15% to 20% when possible, “even if they have to build toward that number over time.”

2. Housing Should Cost No More Than 30% of Income

Old advice suggested that you should spend no more than 30% of your income on housing. Lovely calls this advice “antiquated,” noting that in many parts of the country it’s now unrealistic. Instead, she suggests people aim for “more flexible, values-based planning.”

Morgan pointed out that other cost pressures, like the sudden and steep increase in grocery prices, also eat into housing budgets and leave households with far less room to maneuver.

3. Buy a Home as Soon as You Can

Homeownership was once treated as a smart financial milestone, but that assumption no longer holds. Chad Gammon, a CFP, RICP, Enrolled Agent (EA) and owner of Custom Fit Financial, said this has changed “with more mobility … and the mentality that renting isn’t throwing money away.”

With higher prices, transaction costs and more mobile careers, buying too soon — or in the wrong location — can backfire. “Housing costs are on the rise, buying is often more expensive than renting,” Morgan said.

4. Pay Off All Debt Before Investing

Twenty years ago, high interest rates made aggressive debt payoff a clear priority. Today, the landscape is more nuanced. “There are still quite a bit of low-interest-rate student loans and mortgages out there compared to 20 years ago,” Gammon said.

Often, delaying retirement savings or overworking to pay off debt doesn’t make sense today, Morgan said. “You need to consider both your quality of life and requirements for the future.”
