This estimate is in line with the popular one. That's what travel is all about: you have to have an idea of the moment, the place you've worked so hard to get to and have the good discernment to know that it may be worth paying a little more to make a difference in terms of travel memory. Let's take a very detailed breakdown of what it actually costs to travel around the world during a one-year trip, the costs associated with traveling around the world, and the factors that most dramatically impact your travel budget. I've spent eight years on the road, and almost that time talking to other travelers about budgeting for the trip.
My education was modest, but I was still able to save money to travel and work remotely during the more than 15 years of my travels around the world. It's so addictive to have maximum flexibility and freedom of travel along with the undeniable goodness of regular income, no matter how much digital nomadism changes your trips. This, therefore, is not a guide to how you can travel the world for the least amount of money possible, but rather how travel remains affordable if you choose to stay in nice apartments, splurge on elegant hotels for special occasions, and don't choose the most uncomfortable budget options available. In fact, I make money through this site (as well as with some standalone travel items and royalties from my book), so I work while I travel.
If you're considering long-term travel, your next steps are to come up with a basic itinerary, determine your travel style, and start working out your travel budget. In some unconventional travel destinations where there are no hostels, you'll rely exclusively on the Airbnb and Couchsurfing networks. Traveling slowly is also less stressful for you, and I think you also have a responsibility to yourself and your mental health when you travel. The guide breaks down average travel costs for the world's most visited destinations, which you can use with the fully customizable travel budget spreadsheet to create an accurate upfront budget for your dream trip.
And yes, I am very fortunate that my travel blog fully funds my trips and I have been doing so for more than five years. Perhaps one day I have traveled through the 196 countries of the world and can answer the question of how much it costs to travel the world, but it will still always be just a representation of what I have spent. These costs include air flights, immunizations, visas needed in advance, travel equipment, travel insurance, health insurance, homeschool materials, and so on.
