In the help FAG this formula is given for the calculating the an
individual game rating;

K is a constant (32 for 0-2099, 24 for 2100-2399, 16 for 2400 and
above)

Win Expectancy = 1 / (10^((OpponentRating-YourRating)/400)+1)
New Rating = Old Rating + K * (1 - Win Expectancy)

Where is this formula do you place the variable for whether the game
resulted in a win, lose or draw?

Yes, this is not a very good description. The "1" in (1 - Win
Expectancy) should read 1, 0 or 1/2 depending on whether it is a win,
loss or draw. I think.
