How much is position worth in terms of equity?

This was just a random question popping up in my mind lately. For example, you have a very LAGGY opponent who 3bets you from the BU and you sit with AK in the CO in a 6max cashgame 100 bb effective stacks. His 3bet-range vs you is say 30 percent, so your hand is ofc an easy defend. Lets assume he only 5bets AK, QQ+ and he has a HUGEEE fold to 4bet meaning you might consider flatting oop as a viable option ( Im just trying to get an example in which flatting a 3bet oop is the best option ev-wise).

Now, when you miss the flop and your opponent shows a lot of aggresion youre in a ****ty spot. And the number of situations in which you are oop in poker are ofc. endless. So my question:

How much would playing out of position be worth in terms of absolute equity?

Is there any way to calculate this at all lol? Would be damn useful I think
