Birth control methods compared

By the anquanqi editorial team Updated June 11, 2026

Quick answer

The most reliable birth control methods are long-acting ones — the implant and the IUD — with under 1% failure per year. The pill and condoms work well when used correctly, while calendar-based “safe days” fail for 12–24 in 100 people per year.

Typical-use failure per year

Implant 0.05%; hormonal IUD 0.2%; copper IUD 0.8%; combined pill 9%; male condom 18%; withdrawal 22%; calendar/safe days 12–24%. “Typical use” includes everyday slips — the number that matters in real life.

How to choose

For the most protection with the least upkeep, the implant or IUD are most reliable. Condoms also protect against STIs. The right choice depends on your health and preferences — talk to a doctor.
