100 SR = Amount per tier (Example: Bronze - Silver = 20$ per 100 SR)

A full tier after bronze is 500, so silver to gold would cost $125.

My rates:
Bronze to Silver 20$
Silver to Gold 25$ | Full 500 SR boost = 125$
Gold to Plat 30$ | Full 500 SR boost = 150$
Plat to Diamond 35$ | Full 500 SR boost = 175$
Diamond to Masters 45$ | Full 500 SR boost = 225$
Masters to GM 60$ | Full 500 SR boost = 300$
