The exact definition of implied odds

I've read that the definition of implied odds is the total expected win divided by the current call size.

Surely it also includes any money you've already put in the pot? E.g. if you're in big blind ($20), someone in front of you bets $70, the call size is $70, not $50?

Erm, your call size is 50, the pot is currently 90 (lets say he is SB), will be 140 after your call.

Implied odds take future action into account, for example you have position on SB so if you flop a good hand you will most likely get a cbet from him and maybe one more bet (lets say you X turn to fake weakness and he XC your value bet on river). You can count on this when you are deciding on the preflop call.

To me implied odds are not something you can really figure out to an exact number.(at least i cant) To me i usually think more about implied odds when im behind in a hand with a strong draw.Or if my opponent thinks im behind. Or preflop if i have a smaller pair and someone raises .What will i win if i trip up against what is this pre flop raise costing me.I may be way off (dont think so).But if i am some one let me know.

But LD1977 you've paid $20 already so if you pay another $50 surely your investment is $70 and it is this that you divide the total win by?

Total won / total investment = implied odds
Total pot / call size = current pot odds

What I'm trying to get my head round is, let's say you have pocket pair preflop and your odds of flopping a set are 8:1. Current investment preflop is $50, so the total ROI, as I understand it, for it to be worth a call/raise preflop despite low odds, has to be $400 at least.

The flop comes and you make a set. Do we now disregard the implied odds (at least more so) because we have our draw? Is it now a case of making the ROI (not the pot, the ROI) at least $400 to cater for the times we don't flop a set?

That sounds right to me...

I believe the thinking goes that money you have already put into the pot is no longer yours, it's dead money to you. That's why you only use any extra that you will have to bet to calculate your odds from this point.

Ah yes, that makes sense.
