Everybody loves Calvin & Hobbes, the comic strip created by Bill Watterson that ran from 1985 to 1995. Matt J. Michel of the fictional Proceedings of the National Institute of Science has calculated just how much monetary damage the six-year old Calvin caused to his parents' home over that decade.

Michel used the Complete Calvin & Hobbes Collection to note every instance of damage in the comic. Although Calvin spends a lot of time in imaginary worlds, the report only documents destruction he actually caused to his family home and property.

Michel used Amazon to find the cost of broken items and guessed the mother would probably shop somewhere like J. Crew. For home damage he used the site homewyse to estimate costs.

So, in total, Calvin caused $15,955.50 worth of damage over ten years. Which seems surprisingly low given his reputation, actually.

The most expensive damage he caused over the years was water damage. When he flooded the house in his first year he would have cost his parents almost five thousand dollars.

Interestingly, he caused the most damage in that first year of publication and then became less destructive over time. The longest duration in which no damage was caused was 550 days from 1987 to mid-1988.

In 1989 Calvin pushed the family car out of the garage and into a ditch. Michel estimated no damage was caused to the car but the tow cost would be $95.

Thanks to Matt J. Michel for calculating all this for our enjoyment.
