The Dollar Gain is rounded to the nearest cent and the Percentage Gain is rounded up to two decimals. The formula to calculate Percentage Gain is as follows:

((NP-OP)/OP)*100 = PG
OP = Old Price
NP = New Price
PG = Percentage Gain

Example: Bought Apple stock at $280 and new price is $340. You enter 280 in the Old Stock Price box and 340 in the New Stock Price box. The result is a 21.43 percent gain.
