I am new to BiggerPockets and trying to find out is there a simple calculation sheet on BiggerPockets  already with formulas for figuring the cost for an A to B and B to C transaction.

I am reading the book "Millionaire Next Door" which had been rec'd by a few podcast guests if I recall.They discuss the following formula as a guide to what your net worth should be:Multiply your age times your realized pretax annual household income from all sources except inheritances.

But I'm a different sort of person and could see the formula working.

Is there an easy formula to quickly calculate ROI?
