Martingale stake formula

I've spent a few posts now showing why employing Martingale against fair odds (or in the case of red or black in roulette less than fair odds), that you're always gonna lose.  If you want to read a bit more about it read my post on martingale in roulette begin very bad.

If you've forgotten what martingale is, it basically means everytime you lose, double up your previous bet

Calculating your martingale stake

In one of my earlier posts, i showed you this table, where for a losing streak, how much you'll have to bet to recover

I thought it might be useful to provide a formula that calculate the stake required to cover your losses during a martingale

And that is S = I * (2^(n+1))

I = Initial Stake
n = length of streak
S = Stake Required

Which means Initial Stake * (2 to the Power of the current length of the streak)

So in the scenario where our initial stake is £10 and we've lost 10 times and we need to make our eleventh bet.  Our new stake would be:

£10 * (2 to the power of 10) = £10 * 1024 = £10,240

Obviously you'd be better throwing your money down the toilet but there ya go.  But if you want to calculate it, that's how you do it.

And if you wanna do it in Excel

To do this in Excel with a table like the following

In the cell B4 (stake column row 4) just enter

=POWER(2,A3-1)*$B$3

Obviously you can also calculate it in excel, you can just double up the previous stake.  but the point is to show you how to do when you just know the initial stake and the bet number.

Please don't do martingale with roulette kids, not worth it.
