Curious about the cost of the Nuvo Ring a client had just rejected because of intollerable side effects, I found this chart:

Considering the natural contraception I offer, this means:

Cycle Beads (deluxe) $27 x 1 used for 2+ yrs $13.50/year
Caya Diaphragm $90 x 1 used for 2+ years $45/year
Fem Cap $100 x 1 used for 2+ years $50/year
Contraceptive gel @$25 x 6.5 tubes/yr $162.50/yr
This number is based on 100 uses per year.

IUDs in Canada are less costly, but are used for 3-5 years on average.
Hormonal Contraceptives in Canada $25-45 month $325 to $585/yr
