Reminder: Calculating Effort on the Key Person Tab

As a reminder, the percent effort listed within Coeus’ Key Person tab should be calculated based on the appropriate person months category for the individual’s appointment type: calendar year (CY), academic year (AY), and/or summer term (SM). For example, while VUMC personnel’s effort is calculated using the calendar year (twelve months), external collaborators may use either academic year or summer term methodologies. OSP recommends verifying the listed values and conversions prior to routing in Coeus. To convert percent effort to person months, multiply the percentage of effort associated with the project by the number of months that correspond to the appointment type: 25% of a nine-month academic year appointment equals 2.25 (AY) person months (0.25 x 9 = 2.25) Conversely, to convert person months to percent effort, divide person months by the number of months that correspond to the appointment type: 2.25 person months of a nine-month academic year appointment equals 25% effort (2.25 / 9 = .25) Please note

Resource Toolkit: Converting Percent Effort to Person Months

Person months represent the effort or amount of time PIs, faculty, and other senior personnel dedicate to a specific project. Effort corresponds to the type of appointment: calendar year (CY), academic year (AY), and/or summer term (SM). While VUMC faculty utilize calendar year methodology, please note that collaborators may use either academic year or summer term methodologies. To convert percent effort to person months, multiply the percentage of effort associated with the project by the number of months. For example: 25% of a 9-month academic year appointment equals 2.25 (AY) person months (9 x 0.25 = 2.25) For SF424 (R&R) budgets for competing applications, applicants can include up to two decimal places to represent partial months. For Research Performance Progress Reports (RPPRs), investigators should list person months with whole numbers rounded to the nearest whole person month. NIH has compiled a frequently asked questions page for reference. For more general information, please visit NIH’s website. As always, please reach out to your
