Calculate a teaser bet payout: enter your stake, the original spreads or totals, the teaser points and the quoted odds to see adjusted lines and profit.
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
Enter the cash stake and choose one line type for the list. Enter 1–12 original lines, the point adjustment (6 by default) and the quoted price for the complete teaser in American or decimal odds. Commas, spaces, new lines or semicolons separate lines; do not use thousands separators inside the list. Review the winning net profit, stake-inclusive return and adjusted lines, then open Calculation details.
Dated Teaser Price Presets
The optional DraftKings price reference uses the published table checked November 4, 2026. Choose NFL 6, 6.5 or 7 points, or basketball 4, 4.5 or 5 points, and enter 2–6 lines, one per leg. The number of lines selects the combined price; the result shows that American price and its decimal equivalent. These are named, dated examples, not universal odds or live offers. A combination containing NFL selections uses the NFL table. Use the default custom quoted-price mode for the actual price accepted on your ticket.
For example, the published two-leg, six-point NFL price is −135. A 100 stake gives 74.07 winning net profit and 174.07 total return. The break-even ticket win rate is 1 / decimal odds. Under the additional assumptions of independent legs with equal win probabilities, the per-leg threshold is (1 / decimal odds)1/n, where n is the number of legs. This threshold is not an estimated chance of winning; correlated legs, pushes, voids or unequal probabilities require a different analysis.
Worked Example
With a 100 USD cash stake and a quoted complete-teaser price of 1.91, winning net profit is 91.00 USD and total winning return is 191.00 USD, including the original stake. For team spreads −7 and +3 with a six-point adjustment, the adjusted lines are −1 and +9. Use the operator’s actual combined price; the point adjustment alone does not establish that price.
For an over total, subtract teaser points from the original total. For an under total or selected team spread, add teaser points. Winning net profit = stake × (quoted combined decimal odds − 1). Total winning return = stake × quoted combined decimal odds.
Input and Example Guide
| Input or category | Example or weight | Entry guidance |
|---|---|---|
| Cash stake | 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. |
| Teaser odds for the whole ticket (American or decimal) | −110 (≈ 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 and the actual quoted combined price. Keep the same accepted-ticket conditions throughout a scenario. The tool accepts 1–12 lines as arithmetic; the operator’s actual minimum legs and line eligibility must be checked separately. Exact decimal calculations precede half-up rounding to two money decimals. A positive profit that rounds to zero cents is shown as “Less than 0.01”, with exact and rounded values in the details. Fractional-cent stakes are retained, and independently rounded displays may not add to another rounded display.
Saving and Revising a Scenario
A successful calculation saves a structured input snapshot in this browser and recomputes it when restored. Editing an input retains the last answer as a Previous result until Calculate is selected again. Reset clears user-entered numbers, lines and saved data, and restores the default 6 teaser points, American odds and Team spread choices. Other scripts on this site may access browser storage.

Betfair: decimal odds and stake-inclusive returns; DraftKings: teaser line adjustments and product-specific rules. These sources support the arithmetic definitions and illustrate that settlement rules depend on the product; this calculator does not apply any operator’s settlement rules to a ticket.
