Calculate teaser from your inputs, with a result breakdown and worked steps.
Teaser Formula and Method
Spread and under: add teaser points to the selected line
Select the type of line entered in the list. A spread moves in favor of the chosen team by adding points; an over total moves downward, while an under total moves upward. Each adjusted line is displayed separately. The chosen adjustment is a point amount rather than an odds change.
How to Use This Calculator
Select the result and any applicable method before entering the visible values. Check the selected record, unit and scoring conventions before calculating. Review the primary result and its breakdown, then open the calculation steps to see how the inputs were used.
Worked Example
With the example inputs in the table, the result is 91 USD. Use one line type per calculation and the actual quoted combination price.
Over: subtract teaser points from the selected total Profit = stake × (quoted decimal odds − 1)
Input and Example Guide
| Input or category | Example or weight | Entry guidance |
|---|---|---|
| Money unit | U.S. dollars (USD) | Choose the convention that applies to your record. |
| Cash stake (selected currency) | 100 | Use the stated unit; retain available precision. |
| Line type for this list | Team spread | Choose the convention that applies to your record. |
| Original spreads or totals (points) | -7, 3 | Use matching entries separated by commas or spaces. |
| Teaser adjustment (points) | 6 | Use the stated unit; retain available precision. |
| Quoted full teaser price (decimal odds) | 1.91 | Use the stated unit; retain available precision. |
Interpreting the Result
Enter the bookmaker’s quoted price for the complete teaser to calculate the winning return. A six-point adjustment alone does not determine that price. The calculator does not settle push combinations or mix line types in one list; those details depend on the sport, product and accepted ticket rules.
The line adjustment does not determine the payout price. Push, tie, minimum-leg and sport-specific settlement rules must be checked separately; mixed line types require separate line calculations.
Assumptions and Common Input Errors
Use one line type per calculation and the actual quoted combination price. Keep the same currency and settlement conditions throughout a scenario. Displayed currency amounts are rounded to two decimals; calculations retain precision unless cent allocation is explicitly described.
Saving and Revising a Scenario
