Read Replies (1) | Respond to Tom i asked for ChatGPT AI for one more calculation===>>payback period in miles and energy cost savings when comparing a $30,000 gas car vs. a $65,000 EV .1. Formula for Payback in Miles The break-even mileage is the point where the total cost savings from fuel/energy offset the extra upfront cost of the EV.EV Cost = $65,000Gas Car Cost = $30,000MPG = Fuel efficiency of the gas car (e.g., 30 MPG )Gas Price = Cost per gallon (e.g., $3.50/gallon )Miles per kWh = Efficiency of the EV (e.g., 4 miles per kWh )Electricity Price = Cost per kWh (e.g., $0.15/kWh )2. Example Calculation Step 1: Cost per mile Gas Car Cost per Mile EV Cost per Mile Savings per mile Step 2: Break-even Mileage 65,000-30,0000.0792=35,0000.0792=442,929 miles\frac{65,000 - 30,000}{0.0792} = \frac{35,000}{0.0792} = 442,929 \text{ miles}0.079265,000-30,000?=0.079235,000?=442,929 miles3. Conclusion The EV would only break even after 442,929 miles, which is extremely high and not practical for most drivers. EVs still have lower maintenance costs and potential tax incentives, but fuel savings alone take too long to justify the extra $35,000 upfront. Gas car might be the better financial choice unless there are incentives, high gas prices, or very high mileage usage.
