Your calculations are way off. First there is the length of the house
wiring from the service entrance to wherever you plug in the extension
cord.

A non-issue. The wiring from service entrance to outlets
exceeds NEC ampacity requirements. Rest assured that the outlet
in question is capable of 15 A at less than 500 mV drop, 24/7/365.

Then there is the cord itself and loss at connections which are
rarely perfect. If the combined total length of the house wiring and
the extension is more than 50 feet, you need to get a MUCH heavier
extension cord. 14AWG is not going to cut it.

Good catch, Thanks!
Any of these 14 AWG 15 A 50 foot cords will do nicely:
