What are betting spreads?
Betting spreads, or point spreads, help level the playing field between two teams with different abilities. An oddsmaker sets a spread, which specifies how much a bet on a favorite team must win by for the bet to be successful. On the other side, betting on the underdog wins if that underdog loses by less than the spread or wins the game outright.
Common betting spreads bet types
To make sure you get all the information before taking advantage of betting calculators, here are the three bet types you should know:
| Bet type | Definition | Purpose |
|---|---|---|
| Moneyline | A bet on which team/player will win the game outright |
|
| Points spread | A bet on the margin of victory |
|
| Total (over/under) | A bet that involves the combined total score of both teams over or under that number |

What does using a bet spread calculator look like?
Let’s take a hypothetical NFL game where the New England Patriots are favored to beat the Miami Dolphins with a point spread of -7. In other words, a bet on the Patriots must win by more than 7 points to pay out, while a bet on the Dolphins would pay out if they win or lose by less than 7 points.
So, if you would want to bet $100 on the Patriots with the given spread, here’s what you would get:
| Bet type | Point spread |
| Team | New England Patriots |
| Spread | -7 |
| Odds (American) | -110 |
| Bet amount | $100 |
| Potential payout | $90.91 |
| Break-even % | 52.38% |
With a point spread bet for a -7 spread on the Patriots, you would need to bet $110 in order to win an even $100 with these odds. If the Patriots cover the spread with your $100, you’ll possibly win $90.91. The chances of breaking even in the long run are calculated as 52.38% for -110 odds. Keep in mind that this is just an example and that you might get different results when using a moneyline calculator or any other.
