The best rule of thumb is about 2cm/day ~ 1 inch per day for very cold days (`-25 C, -13F) and 15" ice thickness. Less if the ice is thick; more if the air temperature is colder; less with snow on the ice; more if you're on fresh water rather than sea water.

Go to the last 2 pages of this article to see some graphs (produced by NOAA) at various temperatures, ice thickness, and snow cover for sea water.
