$6,400 per year at 20K miles/year and $4.50 per gallon translates to 14MPG. Maybe for a big SUV, or maybe you drive even more than 20K miles per year.
As for the cost of charging, I have unlimited FUSC but 40% of my charging is still at home due to the convenience. I have solar panels and a municipal utility so that is costing me 5.6 cents/mile. If you're with PG&E your home charging will cost a lot more, especially if you don't have solar panels.
I'm with Sonus. You would need very unusual driving circumstances to get $20K of savings in 3 years. I just hit the $10K in savings mark vs. gas, and I'm 1 month short of 4 years with 61K miles on the 2019 Model S. Only $3,700 of that $10K is attributable to the supercharging being free. About $4K of the $10K is attributable to the home charging being 5.6 cents/mile vs. over 20 cents/mile for gas.
The free supercharging is becoming more valuable over time. In 2019 and 2020 paid supercharging was around 28 cents/kWh. Now it averages 44 cents, and in urban areas with time of use rates it can be 58 cents during peak hours in the range of noon to 9PM.
Yes, large SUV w. V8 -->$6400 was my actual gas spend during 2022 as (premium) here in NorCal was well over $6+ all of last year and as high as $7.09 last June. $20k might be rounding up a bit but I'm coming up with $6000 at 17 mpg x 18k mi. x $6.00/gal. The point stands though, conservatively, I'll be saving $5k in gas expense vs FUSC even with gas now down below $5.50.
