I think these calculations are correct, but insufficient. To properly compare the two cars one must consider a cash purchase of each, then the cost of that money (interest NOT earned from whatever resource one uses - bank, etc.).
Then, consider the probable period of ownership, and the likely percentage of original price to be recovered at that time.
Then, assign a "failure rate" number for the period of ownership and an "average cost of repair" number to each vehicle.
Then, determine the required maintenance cost during that period.
Eventually, you can determine cost per unit of time, or cost per unit of travel - per vehicle. It's worth the calculation in such major purchases as a car, and the differences may surprise you!
You should also talk with (or read posts by) people driving the two cars to get their opinions and gather their experiences. Consider the dealers in the vicinity and the quality of their support. Read the technical reviews and recalls to see whether problems have arisen. Check crash ratings. See how long tires last and what it costs to repair them. Note brake repair costs on the Fit, and the fact that a Prius probably will never need new brakes.
And once the spreadsheet was finished, the discussions were over, the interviews had been conducted, and all calculations were in, my daughter picked the copper-colored one...
