She retired at 40 — and credits K-pop group BTS for making it happen. How fandom turned into financial freedom Emma Caplan-Fisher Mon, September 7, 2026 at 7:00 PM GMT+9 5 min read Kim Hong-Ji/POOL/AFP via Getty Images, Good Morning America/YouTube The retirement plan that actually worked for Bernadette Joy wasn't built around a spreadsheet. It was built around her favorite boy band.

Joy, a personal finance expert and author who spent years helping people with their money, retired last year at 40. She and her husband AJ now live on about $6,000 a month — a lifestyle their savings and investments can sustain comfortably. But the clearest financial turning point, she writes in a personal essay for CNBC, came as she was planning to follow the South Korean pop group BTS on their world tour.

"BTS helped me envision this next step," she wrote. "Attending the shows gave me a specific activity in retirement, which made many of the money decisions easier for me. It also helped me realize that financial freedom isn't about accumulating as much money as possible, but having the flexibility to use my time as I see fit."

By the end of 2027, Joy will have seen BTS perform 20 times on three continents. The cheapest seats were general admission in Brussels, Belgium. She attended her 14th show in Boston and watched AJ make it onto the big screen at their last concert in Munich, Germany.

A decade before she retired, Joy was carrying $300,000 in debt. That context makes the trajectory more striking and her framework more realistic than aspirational.

When BTS announced their reunion tour, she opened a dedicated cash savings account called "Tour with BTS" and refused to fund it by selling investments or using credit cards. She budgeted every expense, from tickets, flights and hotels to food and transportation.

That discipline also reshaped how she thought about her broader retirement portfolio.

"Originally, I had planned to just put my retirement money into investments and brokerage accounts," she wrote. "When I realized how much I wanted to see BTS, it was clear that I also needed more readily accessible cash accounts, too. I had to organize my money around the life I actually wanted to live."

Her current portfolio now includes index funds, money market funds, dividend-producing ETFs and other accessible cash income.

That's the type of mix that can balance growth with liquidity. Fidelity notes income-producing investments "can help support discretionary spending and potential emergency needs in retirement" — which complements growth-oriented index funds in a diversified retirement portfolio.

"This gives me more flexibility and peace of mind," Joy wrote.

Joy's $6,000-a-month spending equals $72,000 per year. Under the widely used 4% safe withdrawal rule — the benchmark that underpins most FIRE planning, according to Forbes — sustaining that spending level would require approximately $1.8 million in invested assets.

But Fidelity's early retirement guide cautions those retiring before 62 to use a more conservative 3% withdrawal rate, adding that 33 times annual expenses is advisable to help savings last through a longer retirement horizon. At the lower rate, Joy's $72,000 annual spending would require closer to $2.4 million saved.

Healthcare is the other critical variable. With Medicare eligibility starting at 65, retirees in their 40s — like Joy — must cover up to 25 years of private health insurance costs. According to Fidelity's Retiree Health Care Cost Estimate, a 65-year-old retiring in 2026 can expect to spend an average of $185,500 on healthcare throughout retirement, and that figure assumes Medicare coverage from day one.

One of Joy's more counterintuitive insights: the freedom of early retirement is disorienting without structure.

"Many retirees I've worked with spent decades having their time dictated by someone else," she wrote. "Then retirement arrives and suddenly every day is theirs. It sounds freeing, but many people, myself included, underestimate how disorienting that can be."

But the BTS tour gave her what she needed: trips to plan, cities to explore and a community of fellow fans spanning more than 20 countries. She also moved with her husband from North Carolina to Las Vegas — partly for the concerts, but also because the city genuinely matched how they wanted to live.

"Las Vegas actually offered the kind of lifestyle we wanted in this stage of our lives: concerts, comedy, entertainment, easy access to national parks and an airport that makes travel relatively easy," said Joy.

Joy's father worked until 72 and had only about 10 years of retirement before he died. She retired in part so that she wouldn't repeat that pattern.

"I spent years learning how to save, invest and build wealth," she wrote. "Now I am learning how to use that wealth to build a life."
