good with numbers/formulas? Please assist

[SlaytheBook]

Hey forum,
I'm looking for the formula that tells you what % you need to win a game at a certain line to stay profitable. I sometimes buy points or play ML favs so just trying to be more calculated with my approach.

What % of games need to win to be profitable at:
-110
-125
-150
-200
and so on.

but really just looking for the formula. And any input from experience and/or links to good articles/insights around this topic would also be appreciated.

Thanks and let's continue to...

Not sure this will help you but might be a start, but I have to admit, damn good/interesting question: https://en.wikipedia.org/wiki/Odds

Here's a quick breakdown. For dogs, it's 1/(1+what you would win). Say it is +120. breakeven is 1/(1.1.2) or 45%. For favs, it is what you risk plus 1. So for -120, it is 1.2(1+1.2), or 55%.Odds Breakeven150 40%145 41%140 42%135 43%130 43%125 44%120 45%115 47%110 48%105 49%even money 50%-105 51%-110 52%-115 53%-120 55%-125 56%-130 57%-135 57%-140 58%-150 60%

To figure out your exact break even % on favorites, use this formula.

-110
110/(110+100)

-200
200/(200+100)

This will give the exact % for breakeven.

I believe that is what DT32 is saying also, maybe just phrasing it slightly different.

For dogs you just move the 100 out of the () and put the price in, plus 100.

+110 (for example)

100/(100+110)

DT32 and JackStraw420 - thanks for the responses and deets, just what I was looking for.

just another reason why the RX is one of the best sports forums out there.
