That's a tough one. There are budget vacations domestically for under $500 and luxury resort vacation that cost more than $5,000. Then too, how many people are you taking with you? Just yourself or a whole family?
I've never heard an actual figure for how much money a person should spend for a vacation. You know the old saying about an engagement ring should cost 3 months salary. I haven't heard anything like that regarding vacations.
But, on average, I tend to spend about $2,000 per vacation for just one person, if that helps you.
