Skipping Financial Planning in Your 40s Could Cost You $200K or More Within a Decade

By the time many people reach their 40s, both earnings and expenses are often at their highest levels yet.

That stage also falls roughly halfway between the start of a career and retirement, making it especially important to have a solid financial plan in place.

Without one, the cost over the next 10 years can add up to hundreds of thousands of dollars.

What Often Happens in Your 40s

For many Americans, one major milestone now arrives later in life: homeownership. The typical age of first-time buyers recently reached 40, a record high, according to the National Association of Realtors. Not long ago, that figure was closer to 30.

After buying a home, expenses tend to go well beyond the monthly mortgage. Homeowners also need to budget for insurance, property taxes, repairs, maintenance, renovations and, in some cases, homeowners association fees.

Those costs can push spending higher across nearly every category. Fidelity data cited in the article shows that annual U.S. household spending typically peaks above $97,000 a year between ages 45 and 54, before retirement savings are even counted.

There is an upside, though: income generally rises as well. A SmartAsset analysis found that median pay is highest among workers ages 35 to 44 at $72,020 a year, with the 45-to-54 group close behind at $71,604.

In other words, your 40s are often a period of both bigger paychecks and bigger bills, which makes financial planning even more critical.

What Poor Planning Can Cost

There is no single dollar amount that fits every household, since the damage depends on factors such as where you live, how much you earn, family size and lifestyle.

Still, attorney and CPA Chad Cummings of Cummings & Cummings Law said failing to plan properly in your 40s could cost between $15,000 and $25,000 a year.

“Over a decade, the real damage can easily reach $200,000 to $350,000 once lost investment growth (opportunity cost and time value of money) enters the equation,” Cummings told MoneyLion. “For high-net-worth households and professionals, that number can reach seven figures fast, especially when we figure in missed estate, tax and risk management (insurance) planning opportunities which can't be corrected after the fact.”

Why A Bigger Paycheck Is Not Enough

Missed retirement contributions are one common way people lose money when they neglect financial planning in their 40s, but they are not the only one. Cummings also pointed to missed employer matches, avoidable interest charges, investments held in the wrong account types, and weak tax and estate planning.

“A household that misses $15,000 of annual savings for 10 years does not merely lose $150,000,” he said. “It also loses decades of future compounding on every missed contribution. That's the opportunity cost.”

He also warned against the assumption that earning more later will automatically solve the problem.

“Your 40s are usually when income rises, but lifestyle costs rise with it,” Cummings explained. “By 50, college expenses or aging-parent obligations can leave much less room to catch up than expected.”
