There is no one definitive answer to the question of how much money one needs to budget for a round the world trip. It depends on your style of travel, where you’re going, and how long you plan to be away. But there are some general rules of thumb that can help you get started.
If you’re planning a leisurely trip with plenty of stops along the way, it’s likely that you’ll need more money than if you’re traveling non-stop. Likewise, if your destination is expensive – like Europe or Australia – then your budget will need to be higher than if you’re headed somewhere more affordable, like Southeast Asia or South America. And finally, the longer your trip lasts, the more money you’ll need to bring with you.
That being said, there are ways to cut costs while on the road. Couch surfing and camping can save you a lot of money in comparison to staying in hostels or hotels; and eating local food rather than opting for Western cuisine will also help keep expenses down. So before embarking on your round-the-world journey, take these factors into account and create a budget that best suits your needs.”
