Answer:
My sister was a cheerleader in high school, so here is what she had to pay. Obviously, your costs won't be exactly the same, but this should give you a pretty good idea of how much it will cost you!
Cheer costs
Uniform - $345 for two uniforms (one for home games and one for away games. Usually uniforms for Varsity cheerleaders cost more than Junior Varsity uniforms, so $345 is for two Varsity uniforms.)
Professional pictures- depend on the brand, but about $170 for a full package
Shoes - $45
Pom-poms - $20 if you want to keep them
Warm-ups - $150
Other attire - $80
Adidas duffel bag - $70
Nationals - $1000
Matching spandex - $15
Under armor - $30
Uniform socks - $4
Cheer camp - $200
