Teaser Calculator
A tool for evaluating multi-leg point teasers: calculate the payout, the breakeven win probability implied by your sportsbook's odds, and the expected value of the play given your own probability estimate.
What Is a Teaser?
A teaser lets you move the point spread or total on multiple games in your favor (e.g. turning a -7 favorite into a -1 favorite) in exchange for reduced payout odds compared to a straight parlay. All legs must win for the teaser to cash.
Common Teaser Sizes
- 6 points - standard NFL/NBA teaser
- 6.5 points - split-number variant to avoid pushing on common margins
- 7 points - wider move, lower payout
- 10 points - "special" teaser, usually limited to 2 legs, moves the number dramatically
How the Calculator Works
- Pick teaser points and number of legs. The calculator pre-fills a typical industry-average payout for that combination.
- Enter (or correct) your sportsbook's actual odds. Payout tables vary by book and by promotion, so the pre-filled number is a starting point, not a quote.
- Estimate each leg's win probability after the tease. This is your own handicapping input - the calculator does not source live lines or results.
- Read the output: potential profit/payout, the breakeven probability implied by the odds, your combined probability of winning all legs, the edge between the two, and the expected value of the play.
Formulas
Profit = odds > 0 ? stake * odds / 100 : stake * 100 / |odds|
Payout = Profit + Stake
Breakeven Probability = odds > 0 ? 100 / (odds + 100) : |odds| / (|odds| + 100)
Combined Win Probability = Leg1% * Leg2% * ... * LegN% (assumes independence)
Edge = Combined Win Probability - Breakeven Probability
Expected Value = (Combined Win Probability) * Profit - (1 - Combined Win Probability) * Stake
Typical Payout Reference (Editable)
| Legs | 6 pts | 6.5 pts | 7 pts | 10 pts |
|---|---|---|---|---|
| 2 | -120 | -130 | -140 | -200 |
| 3 | +160 | +140 | +120 | +80 |
| 4 | +260 | +230 | +200 | +150 |
| 5 | +400 | +350 | +300 | +240 |
| 6 | +550 | +500 | +450 | +350 |
| 7 | +700 | +650 | +600 | +475 |
| 8 | +900 | +800 | +750 | +600 |
These figures are broadly representative of standard sportsbook teaser cards, not a live feed from any specific book. Always confirm against the odds on your slip.
Key Caveat: Correlation
The combined win probability assumes each leg is independent. If two legs are correlated - for example, teasing both the spread and the total of the same game, or two games with a shared outcome driver - the true combined probability can differ meaningfully from the simple product. Treat the calculator's combined probability as an upper-bound estimate for correlated legs.
Why Longer Teasers Usually Have Worse Expected Value
Each additional leg multiplies your required win probability by another factor below 100%, while the payout grows more slowly than the probability shrinks (because the sportsbook prices in its edge on every leg). This is why disciplined teaser bettors tend to stick to 2-3 leg "big number" teasers (rounding to key numbers like 3 and 7 in football) rather than long-leg cards.
