How do I calculate how effective my birth control is?

Do you ever wonder how you can really decrease your chance of pregnancy using birth control and how to calculate it? Well, here you go. First you start with the basics.

Birth Control Method Math Breakdown

How effective* is the…..

Implant? On the implant, 5/10,000 women usually get pregnant. (On its own, the most effective!)

Hormonal IUD? On the IUD with hormone, 2/1000 women usually get pregnant.

Copper IUD? On the copper IUD, 8/1000 women usually get pregnant

Birth control shot? On the birth control shot, 6/100 women usually get pregnant.

Birth control ring? How effective is Nuvaring®? On the birth control ring, 9/100 women usually get pregnant

Birth control patch? On the birth control patch, 9/100 women usually get pregnant.

Combined birth control pill? On the birth control pill, 9/100 women usually get pregnant.

Progestin-only birth control pill (POPs)? On Progestin Only Pills (POPs), 9/100 women usually get pregnant.

Condoms for birth control? Using condoms, 18/100 women usually get pregnant.

*when used as directed. The math changes otherwise.

Now comes the math!

Fearing pregnancy and childbirth is a very real thing. By combining multiple forms of birth control, the math is in your favor. If you really are afraid of pregnancy, I recommend these effective combinations with the lowest chances of pregnancy:

  • the implant + condoms combined = 9/100,000 or
  • IUD with hormone + condoms = 3.6/10,000.

Other common birth control combination math:

  • condoms+ combined birth control pill or patch or ring = 1.6/100
  • condoms+ combined birth control pill + Fertility awareness method = 3.8/1000
