Your numbers I assume monthly joins and 50/50 revshare ....
Based on our
CuriousCash across the board figures on recurring monthly memberships for six months Oct 2005 to Mar 2006 ...
58% first month
71% 2nd month
59% 3rd month
48% 4th month
36% 5th month
22% 6th month
So, using that model and your figures (your actual take with
CuriousCash sites on 50/50 would be an average of $17.89 per join per month across all sites on monthly memberships):
Your figures = 25 sales per day for the month on a $20 join = $25 x $10 (your 50%) x 30 = $7500, but using OUR figures so model is accurate = 25 sales per day on a average take to YOU of $17.89....
Month 1 $13417.5
Month 2 $ 9526.4
Month 3 $ 5620.6
Month 4 $ 2697.9
Month 5 $ 971.2
Month 6 $ 213.7
TOTAL $32447.3
Average take per join = 750 (25 joins per day for 30 days) on a $17.89 join
32447.3 / 750 = $43.3
Hope that is helpful.
