I left an on-site job for a fully remote job, taking about a 35% cut to do so. Literally every aspect of my life improved, including financially.

The financial savings come from 3 things: downsizing to one car and elimination of transport costs; dramatically reduced lunch and coffee expenses; not buying a bunch of stuff to cope with the emotional toll (by far the biggest component).

The savings are even more dramatic if I factor in the opportunity costs of commute time. After accounting for the two way commute time, gas station line time, and vehicle maintenance time, my effective hourly rate working in-office was probably lower than working remote.
