How much does it cost to charge up 120 miles worth of electricity? ![]() How about some math? Compared 300 miles per gallon with 30 miles per gallon. 3 dollars to go 30 miles 3 dollars to go 300 miles If you commute 100 miles per day 5 days a week for 10 years? 5 times 52 equals days per year times 10 years: 2600 miles Now divide that total for 10 years commute by 30 to get how many gallons of gas will be purchased and times that by 3 dollars. OOOOPs I forgot to add 100 miles per day. I need to do that one step at a time (I'm stupid). 5 times 100 equals miles per week: 500 miles per week times 52 weeks in one year: 500 X 52 = 2600 26,000 miles per year times 10 years equals total miles for 10 years commute 260,000 miles (just add one zero) Now divide by 30 (miles per gallon) to get total gallons used in 10 years commute: 8666.67 gallons for 10 years commute. Times that by 3 dollars to get total cost for 10 years with 100 miles per day and 5 days a week commute with a 30 miles per gallon car. 26,000.00 dollars. Check that with a daily cost? 100 miles per day. 100 divided by 30 equals gallons per day: 3.333333 Times 3.33 gallons by $3.00 9.99 or 10 dollars per day. 50 dollars per week 50 times 52 per year is: 2,600 per year 10 years is 26,000 So... 30 compares to 300 with one zero subtracted. 260 dollars per year commute 100 miles and 2,600 dollars per year for the 100 mile per day commute for 10 years. Savings is 26,000 minus 2,600 equals: 23,000 Note: If you pug the thing in at night you can commute 100 miles without buying any gas. How much does it cost to charge the thing up?
