Bubble Lay vs P to Lose

I want to compare the lay bet and the place to lose bets - per bet resolved when the vig charged on the lay is non standard. The bubble machines in Iowa screw the player by charging vig on the total of bet amount AND the win amount.
Example: lay 4 for $100 and when you win the vig is 5% of $150. Vig only charged on wins.

Note: I do have the percentages for the PL wagers
Thank You.

So that's the difference between a $2.50 vig and a $7.50 vig? You get paid $142.50 instead of $147.50 including the bet amount?

Just calculate the total vig you pay and divide it by the total amount you bet (not bet plus win, just bet).

ETA: saw you said it’s only on wins. So then multiply by % if time you win.

For a 4: $100 bet loses 1/3 and wins 2/3 You pay 5%*$150*2/3 = 5%

Corrected numbers above.

For a $100 lay bet on 4 as you describe, you have a 1/3 chance of collecting zero and a 2/3 chance of collecting $150 x .95.

2/3 * 150 * 0.95 / 100 = 95% return or 5% edge

Oops. I agree with this. Messed up that it’s a lay so win 2/3 not 1/3. Will correct my post above
