I think a lot of the issues are with fees, and those fees can eat some of that profit up. For example, if a host charged $0.50 per month for hosting, and they accept paypal. Paypal would charge $0.35 automatically, plus 2%. So Paypal would charge roughly $0.36 in fees. So out of that one month of hosting, the host would profit only $0.14. So Paypal would get more money than the host would. So over twelve months, the fees would add up to $4.32. Now if we had that same scenario but annual payments instead of yearly, the paypal fees for the whole year would be $0.47, and the host would have the other $5.53 in profit. So monthly the host would make $1.68 over 12 months, or yearly the host would make $5.53. Although you as a customer would pay the same amounts either yearly or monthly.
