N2 - We describe in some detail the derivation of a power counting formula for the soft-collinear effective theory (SCET). This formula constrains which operators are required to correctly describe the infrared at any order in the (Formula presented) expansion (Formula presented) expansion). The result assigns a unique (Formula presented) dimension to SCET graphs solely from vertices, is gauge independent, and can be applied independent of the process. For processes with an OPE the (Formula presented) dimension has a correspondence with a dynamical twist.
