What affects the cost of GFCI outlet installation?
Number of locations
Doing several GFCIs in one visit is much cheaper each than a single receptacle.

A missing ground, back-stabbed connections or an overfilled box adds time and may change how the device is installed.
Line vs. load wiring
Wiring the GFCI to protect downstream outlets requires identifying line and load, which takes testing.
