QUESTION: Implied Odds

[imashyboi]

Hi users, I just have a quick question regarding the proper use of implied odds. I understand the concept of implied odds, my problem is whether I am calculating them correctly. Ok, let me write a situation down so people can help me out.

Say your in the CO with 3 players who limped. You are holding AQo and raised(not sure if this is the right play but lets assume that I made the correct move by raising). Both blinds call including the other 3 players. Total of 6 players to the Flop with the pot being 12SBs. Flop comes:

KT9r

SB checks, BB bets out, 2 folds and the last limper check raises. You have 4 solid outs with 15SBs in the pot.

Now, lets say SB folds. Is my implied odds 18SBs = 9BBs. The reason how I got this number is, BB might call the raise since he is already in making the pot 16SBs. The person who raised is probably going to bet again on the Turn putting in another 2SBs on the Turn making the total pot size on the Turn 18SBs. Am I thinking this correctly?

Once all the betting are done on the Flop, do I recount the bets on the Turn to calculate my implied odds on the River? I'm a little confused about this part because some books doesn't include the bets you put in on the Flop to adjust your implied odds on the River.

Let me know if I am thinking this correctly. Thanks
