Early Retirement Through Frugality
Katie and Alan Donegan successfully retired when Alan was 40 and Katie was 35, after a decade of disciplined saving and lifestyle adjustments.
Every winter, the couple deliberately avoided using heating in their home in southern England.
"Instead, we wore extra layers and used hot water bottles - we turned it into a game," says Alan. "It wasn't suffering, it was strategy."
Despite others considering their approach "extreme" or "mad" due to their focus on minimizing expenses, Alan emphasizes their determination.
"We were laser-focused on buying freedom," he explains.
By "freedom," the Donegans refer to early retirement, a goal they achieved seven years ago.
The couple rarely ordered takeaways and consistently brought packed lunches to work.
"We were £40,000 better off over 10 years from just that one lunch habit," says Alan.
They also adopted other frugal habits such as charging their phones while out and searching for discarded Nectar supermarket vouchers.
"You can decide if that's crazy or genius, but it worked."
Alan previously worked as a landscape gardener before founding a training and life-coaching business, while Katie was an actuary for a financial firm.
In addition to their steady incomes, their stringent saving habits allowed them to invest as much as possible.
"Every pound we invested was a step closer to the life we wanted," says Katie.
They retired once their savings reached £1 million.
The FIRE Movement
Alan and Katie are members of the FIRE movement, which stands for "Financially Independent, Retire Early."
Once a little-known concept 15 years ago, the movement now has nearly a million members on its main Reddit discussion board, and many financial institutions publish guides on the topic.
The core principle is living extremely frugally during working years to enable early retirement.
However, for most people, early retirement remains a distant dream due to factors such as the high cost of living, rising property prices, and student debt, which contribute to longer working lives.
Official data shows that average retirement ages in the UK reached record highs last year: 65.8 years for men and 64.7 for women.
Similarly, in the US, average retirement ages have steadily increased since the 1990s, reaching 64.8 for men and 63.3 for women in 2025, according to a long-term study.
Another Early Retiree: Amy Minkley
Despite these trends, some FIRE adherents remain committed to early retirement, such as 49-year-old Amy Minkley.
The American middle-school teacher retired at age 44 after working abroad in Japan, Singapore, India, and Thailand.
Minkley explains that working internationally allowed her to earn higher salaries while benefiting from lower living costs compared to Texas.
She maintained a frugal lifestyle, avoiding expensive clothing, using electronics until they broke, cooking most meals at home, and carefully considering purchases.
"I wasn't interested in keeping up with a certain expat lifestyle," Minkley says.
Living with a housemate in Singapore and India helped her save more, and in several countries she did not require a car, further reducing expenses.
She now resides in Bali, where her retirement income stretches further than it would in the US.
Expert Perspectives on FIRE
Carol Schleif, chief market strategist at BMO Private Wealth in Toronto, acknowledges that FIRE is still achievable for some but notes that many clients prioritize balance.
"If you retire early but don't have friendships, health or a sense of purpose, you've achieved one goal but sacrificed other things… you have to wonder if it's worth it," says Schleif.
She observes that many people now adopt a flexible approach, aiming to reach retirement goals while enjoying life and maintaining meaningful careers.
Sarah Coles, head of personal finance at UK investment platform AJ Bell, warns that the FIRE philosophy is increasingly difficult for most due to affordability constraints.
Nonetheless, she endorses some FIRE principles, such as starting to save early and increasing pension contributions with each pay rise.
"A balanced path can get you the retirement you want, when you want it, without breaking your spirit. It just needs to be more nuanced and realistic," Coles says.
Within the FIRE community, some followers pursue less extreme versions like "Barista FIRE," which involves saving enough to cover most expenses through investments, supplemented by part-time work.
However, for others, extreme frugality remains the primary method to achieve early retirement, a sacrifice they consider worthwhile.
"The principles of Fire are simple, and they haven't changed - spend less than you earn, invest the difference, and give your money time to grow," Minkley concludes.
