While Planned Parenthood clearly could be biased, they state (noteably without a reference) that " Women typically pay between $15 and $50 a month in co-pays for birth control pills — $180 to $600 a year." Even $180 is pretty expensive.

They also claim that " More than one-third of all women voters have struggled to pay for prescription birth control at some point in their lives, and have as a result used birth control inconsistently."

Finally, "On average, a woman spends 30 years of her life trying to avoid pregnancy. That means 30 years of paying for birth control."
