How to use spread betting calculator
Using our betting spread calculator is relatively straightforward! Having settled on your match (what to bet on), you’ll need the points spread that the betting site you’re using has on offer. After that, you’ll need an alternative or substitute spread to compare against what you got.
You can get this substitute either at a different sportsbook (the point spread they’re offering) or the “fair” spread at your initial sportsbook—simply put, without the vig added.
With the two at hand, feed these to our free-to-use betting tool and hit the “Calculate” button. To be clear, here are all the fields/inputs you’ll find on our spread betting calculator.
The inputs
- Fair Spread:
This is the point spread that you’ll find at your betting site for the match you intend to bet on—what you believe is likely to be the game’s outcome.
- Alternate Spread:
This is another point spread sourced from a different sportsbook. Simply put, locate another spread you want to compare against. It could also be the “fair” no-vig spread at your initial sportsbook.
The outputs
- Probability of Winning:
With the fair and alternate spread selected, our calculator will show/estimate the chances of winning with the point spread. In other words, it will give you an idea of how likely that outcome is in percentage (%) terms.
- Fair Lines:
This will show you the true (fair) odds with no vig added. Basically, the true odds of that outcome happening without the sportsbook’s margin.
With all fields covered in great detail here’s an overview (steps) on how to use our spread bet calculator:
- Scout point spreads for your chosen match on one or more betting sites
- Navigate to our calculator
- Key in the points spread offered by your sportsbook
- Enter the alternate spread
- Hit the “Calculate” button to see the results

Example
With the groundwork covered, here’s a real-life example to better illustrate how our betting spread calculator works and gather more insights on the inputs.
Suppose you’re eyeing a WNBA game between New York Liberty and Connecticut Sun and find two (negligibly) different spreads on the same game at various betting sites:
BetRivers
FanDuel
So first, we use our calculator to compute the spreads, with BetRivers being the sportsbook with the fair spread while FanDuel is the alternate for Liberty, which is (-3/-3.5):
| Fair Spread | -3 |
| Alternate Spread | -3.5 |
| Probability of winning | 45.16% |
| Fair lines | 121.44 |
Now, let’s say FanDuel has the fair spread while BetRivers is the alternative. The results will be:
| Fair Spread | -3.5 |
| Alternate Spread | -3 |
| Probability of winning | 54.84% |
| Fair lines | 121.44 |
From the results provided, courtesy of our spread betting calculator, it is clear that you get a better probability of winning for the spread of -3.5 on FanDuel.
Spread betting explained
As dissected in this extensive
spread betting explained
reading, this bet type focuses on the margin of victory rather than the outcome of a game. When dealing with point spreads, you’d be lucky enough to spot chances that can help you place value bets.
So, instead of doing endless calculations, we offer you our spread bet calculator, which you can use to identify the sportsbook whose spreads have the highest probability of winning. If you take the example of Liberty vs Sun on FanDuel, Liberty is the favorite with a spread of -3.5. Therefore, if you bet on the WNBA team, they have to win by 4 or more points for your bet to pay out.
On the other hand, Sun is the underdog, so the bet will still pay even if the Sun loses the game. However, they must keep the points below 3. But why do sportsbooks use half points while women’s basketball does not have halves? Half points are used to avoid pushes or ties, thus guaranteeing the occurrence of either of the two outcomes.

Why is this calculator useful
So, why use our spread betting calculator? The crux lies in identifying betting opportunities in spread bets, which in turn help you place informed bets.

With our betting tool, you can compare two betting sites based on the points spread discrepancy and identify the one that gives you more value for your bets.
