Number of dollars spent per week on a girl divided by number of orgasms attained from said girl. For example if you spend $100 dollars week and you came 5 times FROM THE SAME GIRL that SAME week. Your Jizzcost is 20. The lower the Jizzcost the more financially sound your future may be.

Remember: It's similar to P/E Ratio. $$$/# of Orgasms.
"I know she is hot bro, but have you really analyzed your jizzcost with that girl?" Typically, Jizzcost can be very high for married guys. If you are DINKS your Jizzcost goes down but only if you have a joint account.
