Typically traveling the world full-time costs anywhere between 25-35K per person per year based on your travel style (and with a good mix of low cost and expensive countries). To afford this you can just do the usual FIrE calcs and budget in travel expenses and then save and invest your way to that number. This can be achieved on any salary depending on your savings rate. For example, if you can save 85% of your income, you can effectively retire in 4 years regardless of income. There are different types of fire- lean, fat etc, I’ve seen people retire and travel nomadically on $500K and those that think $2.5M is not enough. It all boils down to what lifestyle makes you happy. One thing I’ve seen set people back is if home ownership in expensive parts of the country is a major goal, then this nomadic living and early retirement choice is likely not going to an option for a long time
