This is because health care subsidies on birth control actually save you money — a lot of money. Every dollar that our society spends on preventing unintended pregnancies produces us “savings of between two and six dollars,” according to a new report from the Brookings Institution. The savings come from averting health care, child care, and other costs associated with unplanned pregnancies. That’s a rate of return of 100% to 500%, making it one of the safest and most profitable investments anywhere.

“Unintended pregnancies are disproportionately concentrated among women who are unmarried, teenaged, and poor,” the report finds. Those are all groups of people who could probably use help affording contraception. If you happen to dislike the idea of your money going to help poor, unmarried, or teenage women, consider the fact that you will not just get your money back, you’ll at least double it and at most quintuple. You’ll enjoy this profit in the form of lower health care costs and lower taxes.

The reverse may also be true: spending less money on contraception services leads to higher health care costs and higher taxes.
