Comparing the effectiveness of birth control methods and how to choose what’s right for you
TLDR:
When used correctly, most birth control methods are highly effective. Hormonal options like IUDs and implants have success rates over 99%, while typical use of the pill or condoms may be less effective due to human error. Your lifestyle and health goals can help determine the best option.

Understanding Birth Control Effectiveness
When asking “how effective is birth control,” it’s important to distinguish between perfect use and typical use. Perfect use refers to how effective the method is when used exactly as directed. Typical use reflects real-life scenarios—missed pills, improper condom application, or delayed injections.
Effectiveness rates are usually measured by how many people out of 100 will get pregnant each year while using a specific method. For instance, a method that is 99% effective means that 1 out of 100 users will become pregnant annually.
Highly Effective Birth Control Methods (Over 99%)
1. Intrauterine Devices (IUDs)
- Hormonal IUD (e.g., Mirena, Kyleena): >99% effective
- Copper IUD (e.g., Paragard): >99% effective
IUDs are small, T-shaped devices inserted into the uterus by a healthcare provider. Once in place, they offer long-term protection without requiring daily action. Hormonal IUDs can last 3-8 years, while copper IUDs can last up to 10 years.
2. Birth Control Implants (e.g., Nexplanon)
- 99% effective
A matchstick-sized rod is inserted under the skin of the upper arm and releases hormones that prevent ovulation. It lasts up to 3 years and is one of the most low-maintenance options available.
Very Effective Methods (91–99%)
3. Birth Control Pills
- Perfect use: ~99% effective
- Typical use: ~91% effective
Pills need to be taken around the same time every day. Missing doses or taking them irregularly reduces their effectiveness. Combined pills (estrogen and progestin) are common, but there are also progestin-only options.
4. Birth Control Patch and Vaginal Ring
- ~91% effective with typical use
These options release hormones similar to the pill. The patch is replaced weekly, and the ring is typically used monthly. Like pills, forgetting to replace or insert them on time can reduce their effectiveness.
5. Birth Control Shot (Depo-Provera)
- ~94% effective with typical use
The injection is given every 3 months. It’s convenient, but effectiveness depends on receiving the shot on schedule. Missing an appointment can leave you unprotected.
Moderately Effective Methods (76–88%)
6. Male Condoms
- Perfect use: ~98% effective
- Typical use: ~82% effective
Condoms also provide protection against sexually transmitted infections (STIs), unlike hormonal methods. However, slippage, breakage, or incorrect use can reduce their effectiveness.
7. Female Condoms
- ~79% effective with typical use
Similar in concept to male condoms, but worn internally. They’re less common and may be more difficult to use correctly.
8. Withdrawal Method (Pulling Out)
- ~78% effective
This method relies entirely on timing and self-control, which makes it far less reliable than other options. It’s also not protective against STIs.
Less Effective Methods (Below 75%)
9. Fertility Awareness or Natural Family Planning
- ~77% effective with typical use
This involves tracking menstrual cycles, body temperature, and cervical mucus to avoid sex on fertile days. It requires consistent tracking and is best suited to those with regular cycles.
10. Spermicide and Contraceptive Sponges
- Spermicide alone: ~72% effective
- Sponge: 76–88% effective depending on prior births
These methods are often used in combination with condoms to improve effectiveness, but they offer little protection when used alone.
Emergency Contraception: How Effective Is It?
Emergency contraception (EC) is not a regular birth control method but can prevent pregnancy after unprotected sex.
- Plan B (levonorgestrel): ~89% effective if taken within 72 hours
- Ella (ulipristal acetate): More effective than Plan B, especially closer to ovulation
- Copper IUD: Can be used as EC and is >99% effective if inserted within 5 days
What Impacts Birth Control Effectiveness?
Several factors can influence how well your birth control works:
- Consistency and Correct Use: Missing pills, late shots, or improper condom use reduce effectiveness.
- Interactions with Medications: Some antibiotics and seizure medications can interfere with hormonal birth control.
- Body Weight: In some cases, weight can affect how well certain methods (like the patch) work.
- Health Conditions: Medical issues may require different birth control strategies or affect how your body responds to them.
How to Choose the Right Method
The best birth control method for you depends on a variety of factors:
- Are you looking for long-term or short-term protection?
- Do you want to avoid hormones?
- Is STI prevention a priority?
- Do you plan to get pregnant soon?
- Can you commit to daily or scheduled use?
Talking with a provider can help you balance these considerations with your health history and lifestyle.

FAQ: How Effective Is Birth Control?
Q: Is any birth control method 100% effective?
Only abstinence is 100% effective. However, methods like IUDs and implants are over 99% effective with typical use.
Q: What’s the most effective birth control for teens or young adults?
LARCs (Long-Acting Reversible Contraceptives) like IUDs and implants are often recommended due to low maintenance and high success rates.
Q: Do condoms protect against pregnancy and STIs?
Yes. Male and female condoms are the only methods that protect against both.
Q: Can I get pregnant if I miss one birth control pill?
It’s possible, especially if it’s early or late in your cycle. Take the missed pill as soon as you remember and use backup protection.
Q: Is it okay to use two birth control methods at once?
Yes, especially if combining a barrier method like condoms with hormonal birth control for added protection and STI prevention.
