5 Tips From Early Retirees

At 31, Robert Charlton had grown disillusioned with his job as a technical writer. "The idea of doing a desk job for another 30 years seemed painful to me, so I came up with this idea of trying to retire before 45," he says. He shared the idea with his wife Robin, who was then 31 and working as a travel agent.

Robert read up on personal finance instead of hiring an adviser and looked at taxable accounts they could draw from before turning 60. During that period, Robin completed an accelerated nursing program to become a registered nurse. By age 43, they'd gone from $16.88 in their checkbook at age 28 to saving up enough money to leave both their jobs and live off the interest.

Now, years later, they travel the world, skydiving in New Zealand, hiking through India, sailing through the Chilean fjords, and documenting their adventures on their website, wherewebe.com. Although many people struggle to retire in their 50s or 60s, Robert believes it's possible for others to retire early as he and his wife did. "Really, we're very average people," he says, admitting that it's harder, though not impossible, for those with kids. "We never had power jobs. We just both took intelligent steps." Here are some of those steps.

1. Cut housings costs. The Charltons spent a year carefully tracking their spending to see where they could cut back. But as Robert says, "the truth of the matter is, we really didn't have that much fat to cut out." Still, they agreed to rent out half of the bi-level starter home they owned in Boulder, Colo., so they could pay off the mortgage and pad their savings. Switching from a 30-year to a 15-year mortgage also helped the couple reach their goal. "You save so much on interest that it does result in a higher monthly payment, but not as high you would think," says Robert. They later sold their house and put the equity into a bond fund.

2. Agree on your priorities. Instead of buying new cars, the couple kept their old ones, and Robin stuck to grocery shopping lists instead of buying whatever caught her eye. "That's how he shopped [without sticking to the list] so he was cut off from shopping," she says. Keeping their shared goal in mind kept their eyes on the prize. "We were both on the same page," adds Robin. "We both knew we wanted to put the money towards experiences." However, because they value travel so much, the Charltons didn't completely deprive themselves while saving up for retirement. As Robert says, it's important to "balance living for tomorrow with living for today." If saving feels like too much of a chore, it's easy to fall of the bandwagon.

3. Live below your means. Now that they've left the workforce, the Charltons live modestly by staying in hostels and focusing on less expensive travel destinations. They estimated needing between $30,000 and $40,000 annually, and they've managed to stay in that range, though they're averaging closer to $40,000. Earlier this year, they splurged on a trip to Italy and Switzerland for their 25th wedding anniversary. However, Robert says, "we typically have tried to travel places where the dollars goes further, like Argentina and Chile, where the exchange rate was in our favor." Destinations like India and Nepal have higher airfare but low day-to-day expenses so they stay for several months at a time to balance out the airfare costs.

4. Stay in the game. Although the Charltons' portfolio has had its ups and downs, they've resisted the urge to try to time the stock market or get out altogether. "We did some of our best investing during the bear market of 2000 to 2003," says Robert. "We bought stocks 'on sale' and reaped the rewards afterwards." Although he says they could have gotten a higher return on investment if the timing had been different, they also underestimated future earnings, so that helped them reach their target more quickly than planned.
