Pro-Rate
Pro-rate is the partial-month billing for members who join mid-cycle. A student joining on the 15th of a 30-day month at $90 is charged $45 for that partial month, then full price from month 2. Pro-rating reduces signup friction (no awkward "pay full month for 2 weeks" conversation) and increases mid-month enrollment by 15-30%. Most studios pro-rate to the day; some pro-rate to the week for simplicity.
