This is a trick question! There is no set amount that you should spend on golf clubs… only what you’re comfortable with (or what the household CFO allows!).
Spending two or more month’s salary on a set of clubs is in no way a guarantee for anything. It’s similar to going from a $50 pair of shoes to a $300 pair (assuming both pairs fit your feet and are similarly styled) and expecting to jump higher and run faster… It just ain’t gonna happen.
What matters most is how the clubs are fit to your swing and body type.
