Ok so here my question

What Percentage of wagers need to be won to profit from Odds say +200 thru -200

So my chart would look as follows

+200
+190
+180
+170
+160
+150
+140
+130
+120
+110
100
-110
-120
-130
-140
-150
-160
-170
-180
-190
-200

I googled it and remembered seeing on a forum once but can't find it anywhere

Thanks groovey :)

-xxx means bet xxx to win 100. So you need to win xxx/(xxx+100). Eg, at -200, you need to win 200/300 = 2/3 to break even.

+xxx means bet 100 to win xxx. So you need to win 100/(xxx+100). Eg, at +150, you need to win 100/250 = 2/5 to break even.

Axiom,

That is so nicely explained; thanks! That puts it in a way that helps me understand it better; hope it helped the OP as well.

this has been sitting around
same formula used

but if you know one say +200, you should know -200
700	12.5000%		-700	87.5000%
600 14.2857% -600 85.7143%
500 16.6667% -500 83.3333%
400 20.0000% -400 80.0000%
390 20.4082% -390 79.5918%
380 20.8333% -380 79.1667%
370 21.2766% -370 78.7234%

320 23.8095% -320 76.1905%
310 24.3902% -310 75.6098%
300 25.0000% -300 75.0000%
290 25.6410% -290 74.3590%
280 26.3158% -280 73.6842%
270 27.0270% -270 72.9730%
260 27.7778% -260 72.2222%
250 28.5714% -250 71.4286%
240 29.4118% -240 70.5882%
230 30.3030% -230 69.6970%
220 31.2500% -220 68.7500%
210 32.2581% -210 67.7419%
200 33.3333% -200 66.6667%
190 34.4828% -190 65.5172%
180 35.7143% -180 64.2857%
170 37.0370% -170 62.9630%
160 38.4615% -160 61.5385%
150 40.0000% -150 60.0000%
140 41.6667% -140 58.3333%
130 43.4783% -130 56.5217%
120 45.4545% -120 54.5455%
110 47.6190% -110 52.3810%
100 50.0000%
easy way to remember formula
you have some money $X and want to turn it into $Y (your bet + winnings or the total return)
X/Y

you have $100 and can win $115 (+115)
= 100/215 = 46.51%
so -115 = 1 - 46.51%
