Why Win Rate Is a Terrible Metric for Serious Bettors
Educational overview of why win rate misleads.
The Flaw in Win Rate: A Serious Bettor's Guide
=====================================================
The Problem with Win Rate
---------------------------
Win rate is a flawed metric for serious bettors. It fails to account for breakeven win rates at -110, where a 50% win rate is required just to break even.
What Does This Mean?
------------------------
Imagine you have a system that wins 55% of the time. Sounds good? Not so fast! If you're paying -110 odds (a common vig), your actual win rate needs to be higher than 50% just to break even. The vig eats into your profits, making it harder to achieve a positive return.
The Math Behind It
----------------------
Let's look at an example:
| Win Rate | Actual Win Rate (breakeven) |
| --- | --- |
| 50% | 50.0% |
| 52% | 51.1% |
| 55% | 54.5% |
As you can see, the actual win rate required to break even increases as the vig does.

Ask Signal (3 example questions)
---------------------------------
* Q: "I have a system that wins 60% of the time. Is it profitable to make money?"
A: No, not necessarily. You need to consider the vig and actual win rate required to break even.
* Q: "Why is CLV (Cash Loss Value) a better metric than win rate?"
A: Because CLV takes into account the vig and provides a more accurate picture of your performance.
* Q: "I'm using a system that has a 55% win rate. Is it working well?"
A: Not necessarily. You need to calculate the actual win rate required to break even, taking into account the vig.

FAQ
What is a breakeven win rate?
A breakeven win rate is the percentage of wins required to cover the vig (juice) charged by sportsbooks. At 50% win rate, your returns are exactly offset by the vig.
How does the vig affect my betting results?
The vig eats into your profits because it's built into the odds. A higher vig means you need a higher actual win rate to break even and achieve a positive return on investment.
Why isn’t a 55% win rate automatically profitable?
A 55% win rate is not automatically profitable because it doesn't account for the vig. To actually make money, you need an actual win rate that exceeds 50%, which requires more wins than losses to compensate for the sportsbook’s cut.
