Step 1: Enter the Purchase Price
of the coin. Reset field first, if
needed. 
Step 2: Enter the Selling Price of
the coin (or best
estimate of what the coin is worth). 
Step 3: Enter the number of Years
Held. Count the year purchased as Year 1. You may use entries such as
4.75 (for 4
years, 9 mos.) to fine tune your result. 
Step 4: Then, click on the
"Calculate Coin Annual % ROR" button to view the coin's compounded
annual rate of return percentage. 
This calculator does not compute negative
rates of return. Therefore, the entered Purchase Price must always be
less than the Selling Price. The number of Years Held must be 1 or more.
