Click on column labels to sort by that column. 7 is the average result for a throw of two dice, and so it is assumed utilities will always recieve £70 each, should both be owned.

n
Number of properties in the group.
r (return)
The total rent collected over all the properties in the group, assuming maximum hotels. (i.e. the cost if someone landed on Mayfair and Park Lane, in the same turn, when both have hotels.)
c (cost)
Total building cost for purchasing, at standard rate, and buying hotels.
P
Probability of someone landing on the group
Ac
Average cost. This is the total cost for the group, divided by the number of properties in the group.
Ar
Average return. This is the total return/rent for the group (see r), divided by the number of properties in the group.
Ar/turn
Probability of landing on the group, multiplied by the total return for the group; this represents (assuming that over the course of a game, everyone lands on every square an average number of times) the revenue per turn from this group on average.
ROI 1
A measure of return on investment, calculated as the ratio c:r (to three significant figures). The higher the figure, the better.
ROI 2
A different measure of return on investment, calculated as the ratio between Ac:Ar/turn (to three significant figures). This represents a measure of how the average rent per turn of one of the properties compares to the cost of building up that property, and is probably a more useful measure than ROI 1. The higher the figure, the better.
