USAID currently has long-term agreements with suppliers who package their POPs in packets of 35 pills and does not provide any POPs in 28-day packs. *CYP is based on COCs being packaged in packs of 28 pills.

CYP was updated in 2000 by the EVALUATION Project in 2011 by the RESPOND Project and most recently in 2022 by FHI 360, Avenir Health, and USAID. USAID issued a slightly modified set of conversion factors, which the Agency used since 1997. The EVALUATION Project undertook an extensive review of the literature and empirical data on a number of the variables that form the underlying assumptions for the calculation of CYP. The CYPs for each method are then summed over all methods to obtain a total CYP figure.įor some methods like condoms, coital frequency and effectiveness are the most important inputs for the CYP calculation while for methods like intrauterine devices (IUDs) and implants, labelled duration of use and continuation rates are used in the calculation. The CYP for each contraceptive method is calculated by multiplying the number of units distributed (for sale or for free) to clients over a defined period, usually 12 months (could be a calendar year or fiscal year) by a conversion factor that quantifies the duration of contraceptive protection provided per unit distributed and per procedure. This includes permanent methods, such as sterilization, and the lactational amenorrhea method (LAM). The estimated protection provided by family planning (FP) methods during a one-year period, based upon the volume of all contraceptives sold or distributed free of charge to clients during that period.
