Measuring Effort in Person Months

Many funding agencies measure project personnel effort in person or calendar months rather than percentage (%). The National Institutes of Health (NIH) define person months as:

The metric for expressing the effort (amount of time) PD/PI(s), faculty and other senior/key personnel devote to a specific project. The effort is based on the type of appointment of the individual with the organization; e.g., calendar year, academic year, and/or summer term; and the organization's definition of such. For instance, some institutions define the academic year as a 9-month appointment while others define it as a 10-month appointment.

Example: A faculty member with a 12-month appointment committing 10% effort would be reflected as 1.2 person months in a proposal budget.
