How teaser math works

A teaser ticket wins only if every leg wins, so the ticket’s break-even probability is spread across all the legs.

Read our methodology →

FormulasD = decimal price, n = legs, pᵢ = leg win chance

ticket break-even = 1 ÷ D
each-leg break-even (equal, independent legs) = (1 ÷ D)^(1/n)
ticket win chance = p₁ × p₂ × … × pₙ (independent legs)
EV = ticket win chance × D − 1

Example: 2-team teaser at −120

Ticket break-even = 54.55%
Each leg, if equal: square root of that = 73.85%
Legs at 75% each: ticket wins 56.25%, EV 3.13% ($3.13 per $100)

The each-leg figure is usually an irrational root; slipmath rounds it with exact arithmetic, never floating point.

Example prices

Break-even by teaser price

Common price points for illustration — your sportsbook’s table will differ by sport, points and number of teams, so always use its actual price.

Each leg needs (equal legs)ticket break-even in brackets

2 teams at −120: 73.85% (54.55%)
2 teams at −110: 72.37% (52.38%)
3 teams at +160: 72.72% (38.46%)
3 teams at +180: 70.95% (35.71%)
4 teams at +250: 73.11% (28.57%)
4 teams at +300: 70.71% (25.00%)
5 teams at +400: 72.48% (20.00%)
6 teams at +600: 72.30% (14.29%)

Reading the table

A better price lowers the bar: −110 instead of −120 on a 2-team teaser drops the per-leg break-even from 73.85% to 72.37%
At a fixed price, every extra team raises the per-leg bar; sportsbooks offer longer prices for more teams, so the net effect depends on both the price and the team count — compare against straight parlays with the parlay calculator
Whether teased legs actually win that often is the whole question — the calculator takes your estimate, it does not supply one

What this calculator assumes

Teaser rules vary by sportsbook and teaser type. The math above holds only inside these limits.

Outside the model

Pushes: books may reduce the ticket to fewer teams, grade it as a loss, or void it
Legs from the same game, or otherwise related, are not independent — multiplying their chances can mislead
The value of the extra points depends on the sport and the line; enter your own leg estimates. Check any single price with the EV calculator

A positive EV is never a guarantee for one ticket. If betting stops being fun, see our responsible gambling page.

FAQ

Frequently asked questions

How does a teaser bet pay out?

A teaser is a parlay of point spreads or totals moved in your favour, paid at one fixed price for the whole ticket. A 2-team teaser at −110 pays like any −110 bet: $110 returns $210.00, a profit of $100.00. Every leg has to win. Prices depend on the sportsbook, the sport, the number of teams and the points — enter your book’s price.

What win rate does each teaser leg need?

If every leg has the same chance, a 2-team teaser at −120 breaks even when each leg wins 73.85% of the time (the ticket itself needs 54.55%). A 3-team teaser at +160 needs 72.72% per leg. That per-leg figure assumes equal, independent legs with no pushes or voids — it is a shared threshold, not a separate bar each leg must clear, and legs that tend to win or lose together need a different calculation.

Is a teaser a good bet?

Only if the teased legs win often enough. At −120 with two legs you estimate at 75% each, the ticket wins 56.25% of the time and the bet is 3.13% EV. At −110 with 72% legs it is −1.03% EV — small changes in your leg estimates flip the answer, and the calculator cannot know how much the extra points really help.

What happens if a teaser leg pushes?

House rules differ: many sportsbooks drop a pushed leg and pay the ticket as a teaser with one fewer team, some grade a 2-team teaser with a push as a loss, and others void it. This calculator does not model pushes or cancelled games — check your sportsbook’s teaser rules.

Can I tease two sides of the same game?

Many books restrict it, and even where allowed, legs from the same game are not independent. The expected value here multiplies leg probabilities, which assumes independent legs; for correlated legs the result can be badly off.
