Dave Ramsey Says Divorced 40-Year-Olds Can Still Retire Rich. Here's What the Math Actually Shows

A caller described divorce, a mid-career salary, and a high-mileage vehicle while asking whether retirement was still possible. The response emphasized that the math for reaching retirement by age 65 is achievable with disciplined saving and investing. The plan used investing about 15% of household income, roughly $1,000 per month, at a 10% annual return to project about $1.4 million at retirement. The projection depends heavily on assumptions, especially the return rate and inflation. Inflation reduces purchasing power, so a nominal nest egg may not match today’s buying power. Using a more conservative 7% real return leads to about $800,000 in today’s dollars, which can still support retirement with Social Security and a paid-off home.

"The biggest thing you have to overcome is not the mathematical challenge of being okay by age 65, because that's a laydown. You definitely are going to be fine. You're going to be a multimillionaire."

"Then they ran the numbers: invest 15% of household income (around $1,000 monthly) at a 10% return, and you arrive at retirement with about $1.4 million. If you believe the math but skip the assumptions behind it, you might either underestimate what's required or overestimate what you'll end up with. Both errors are expensive."

"The math works, but the return assumption is doing the heavy lifting. The advice is directionally right. A 40-year-old who invests $1,000 a month from now until 65 has 25 years of compounding ahead. At a 10% annualized return, that contribution stream lands in seven-figure territory. The Ramsey camp uses 10% because that's roughly the long-run nominal return of the S&P 500 since the late 1920s."

"Inflation eats real purchasing power, and the Fed's preferred gauge, core PCE, sat at an index level of 129.28 in March 2026, up 0.7% in a single month. A $1.4 million nominal nest egg in 2051 will not buy what $1.4 million buys today. Plug in a more conservative 7% real return assumption (closer to the S&P 500's inflation-adjusted long-run figure), and the same $1,000 a month for 25 years ends up closer to $800,000 in today's dollars."
