Did you really think that traveling the world with your family would be cheap? Guess again.

It used to be a good idea to be prepared, but while easyJet and Ryanair continue to discount fares, many airlines raise airfares as economies around the world get back on track.

Even if you purchased a savings plan (visit savingspeaks.com for a list of one of the best), you might not have saved enough. The web site Trekaday.com estimates that a family of four would have to spend $34,935 to travel the entire world and recoup at least $15,000 in expenses including food, shelter, school and hobbies.

To put it another way, the family of four would pay $2,850 per month to fund that adventure in exchange for about a 10 percent chance of completing it. Ouch.

This is the world as it is: expertly constructed, insanely expensive.

Thankfully, if you are brave and not a pathological worrier (okay, you don’t have to be brave), a one-year emergency travel fund can save you thousands.

We spoke with Robert Delley, a personal finance blogger at Travel With Robert who travels all over the world and wrote the book He’s Only Famous For That. He explained how much he spends with his family during the 12 months before traveling to a destination.

The best way to save is to have money in a savings account (ideally with a bank that has relatively high interest rates) that gives you a payback of over 5 percent per year.

The main challenge when researching how much you can save without going broke, is that most people have misconceptions about what savings accounts offer.

Many people think they only have to save enough money to pay the interest on a savings account. That’s not true. Most savings accounts have a 1.25 percent annual interest rate, so you would earn 1.25 percent on your money, not 1.25 percent interest on your money.

What you really need to do is earn a larger amount on your money.

The next best thing is a CD or a money market account that pays 1.25 percent to 1.50 percent interest, but Delley recommends a savings account with the highest APY for any savings account and hopefully earning over 5 percent. You have to let the money work for you, but an above-average rate of return is better than a low rate of return.

“Depending on where you are in your life, waiting to save might not pay off,” Delley said.

Delley advises that as soon as you start to build your emergency savings, always plan to maximize that account.

This can be done by taking the money in your savings account and taking that money out to get the highest interest rate possible to earn on it. If you really want to go for the highest rate, you can put that money into a CD or money market account and get an even higher rate of return on it, but you will have to wait.

The final way to maximize your savings and accelerate your money growth potential is to focus on growing your investments, which comes in many forms, such as buying mutual funds or a stock. When you buy mutual funds or stocks, your money grows faster because you invest in a pool of money that will be managed by professionals.

Delley said that most people don’t take the time to think about long-term savings since they are too busy, busy with their lives.

“People don’t understand that people’s lives take place three to six months to a year ahead of them,” Delley said.
