Ice skating varies. The skates for someone into it range from $500-$1500. Those typically last several years unless you're skating like 4 hours a day and doing tons of jumps. It costs $20 to sharpen skates and that needs to happen every few weeks for competitive skaters I think. I like mine slightly dull and usually go a few months at a time. Lessons are like $200+ per month for group or $40+/hour for private. Travel + recitals + outfits + music, would be another thing too, but we don't do the competitive stuff. As a result, I pay a lot more for hockey for my kid. I could see figure skating being a little more expensive overall if we were competitive and did more private lessons. They're both super expensive in general though.

When my kids played hockey the team bought a skate sharpener. Saved a lot of money over the years not paying for sharpening at the rinks (and often the rinks would do a poor job at it, depending on whether the person knew what they were doing).
