The Dollar Rule Ratio

We're going to do a little math now. But I promise it'll be simple. This is probably as mathematical as we're going to get with the Dollar Rule.

Because every purchase involves different prices and time of use, the break-even point varies a lot from item to item. It's hard to compare the break-even point of a toaster to a video game, or lawn service to basketball tickets.
