N0 is calculated as variance / (ev^2) or (standard deviation / ev) ^ 2 [where ^2 means squared]

For more complex cases, like blackjack (which I might infer is the case here based on your stated 0.5% disadvantage), we obtain the ev (edge) and standard deviation by simulating the game. However in that case, the simulator can also calculate N0 for you.

I'm just now noting that you are trying to demonstrate a 0.5% disadvantage. In that case, the probabilities I quoted above are those for being at or below expectation. Forgive me, we're mostly concerned with working with advantage situations here.

The results of the simulation will tell you the advantage (or lack thereof) for using your strategy and other useful things, like how much you should be betting, risk of ruin, variance, N0, bankroll requirements etc. for what you are betting.

Blackjack strategies are too complex for simple calculations. You really need to simulate your strategy.

I see that you're new here, so let me say that, if it's some kind of progression or money management strategy, then forget about it. Those can not overcome the house edge.
