A 2001 study conducted by the Guttmacher Institute found that the average overall cost of an abortion in the United States was $468, a figure that has probably risen since then due to inflation, but that the average amount paid for an abortion (due to subsidies) is $372.
The Guttmacher Institute has also found that 87% of private health care plans cover abortion services--but because a disproportionately high number of people have substandard plans, only 46% of American workers are covered by policies that include abortion.
Second-trimester abortions tend to be more expensive. At the Jackson Women's Health Organization, Mississippi's only remaining abortion clinic, a surgical abortion costs $405 if the pregnancy is in the first trimester, $495 at weeks 13-14, and $640 at weeks 15-16.
Conventional wisdom would suggest that an abortion induced via RU-486/Mifepristone would cost less than a surgical abortion, but this is not necessarily the case. The Jackson Women's Health Organization, for example, charges $520 for a first-trimester RU-486 abortion--$115 more than a surgical abortion would cost.
