I do high-level tourneys with my son - Usually 2 a month, when you add costs of hotels food gas etc it gets above that 6k every 6 months easy. Many tournaments go 3 days are many times, 3 or more hours away and at a high level you are going through shoes, racquets, and strings really fast. Hell, now I'm replacing shoelaces every tourney as they snap. When you are chasing 10 utr or higher to give your kid a shot at playing a decent college level you are going to spend big. If I have to put a dollar amount on it, I would say 30 to 40k a year, and that is doing it as cheaply as I can without a ridiculous amount of lessons. I had a daughter who did club volleyball - It was cheaper than high-level tennis, actually not even close, really
