I feel like everyone jumped on this question to brag about how expensive professional skating is when recreational skating isn't bad at all. The OP didn't specify if they wanted to know about Olympic skaters or recreational skater costs. Did the OP want to skate themselves and is now terrified of the costs?
Recreational skaters are only spending $2,000-$5,000 a year depending on how much they like to travel and compete. If you live in an expensive big city, then yeah, you'll easily hit $10,000 as a recreational skater, but small towns are going to be much cheaper for coaching and ice time.
Recreational skaters aren't taking lessons with overpriced elite coaches and they only skate about 7-10 hours a week or less.
They might only do 1 or 2 local competitions and barely travel at all.
They can buy unstoned dresses, stone it themselves , and then reuse that dress several times before getting something new.
There's even a potential to buy stuff second-hand from other skaters.
Recreational skaters (whose feet have stopped growing) will have skates that last from 3-5 years before needing replacement. They also don't usually have to buy boots/blades made for anything but singles and maybe doubles.
They aren't required to do ballet or any extra activities off the ice since they're just recreational. It's a personal choice how much of that, if any, they want to add in.
They can go to normal public school like most kids.
At the recreational level, most people cut their own music, or have a friend or coach do it, often for free, or for a VERY small fee.
Their main coach will also throw together choreography for a program. They don't have to hire a totally separate person for that.
If you're really lucky, a lot of these smaller rinks have "jack of all trades" coaches, so you don't even have a separate MIF coach or Dance coach you have to pay.
