Moneyline betting, plain

What is a moneyline bet?

A moneyline is the simplest bet on the board: pick which team or competitor wins, no points or runs added or subtracted. The favorite is priced with negative American odds (e.g. −150 means risk $150 to profit $100). The underdog is priced with positive American odds (e.g. +200 means risk $100 to profit $200).

Available on virtually every game in every sport — NFL, NBA, MLB, NHL, soccer, UFC, tennis, even individual matches in golf.

How big is a typical moneyline favorite or underdog?

Spread sports (NFL, NBA, college football, college basketball) have a wide range. A 3-point home favorite is usually around −150 to −170 on the moneyline. A 7-point favorite might be −280 to −320.

In baseball and hockey — sports without traditional spread bets — moneylines are tighter. Most MLB favorites land between −110 and −180. Underdog prices like +200 or +250 are common in MLB but rare in NFL or NBA.

Heavy moneyline favorites in major-league action — −500 or worse — usually appear in mismatched playoff games or marquee tennis matches with top-10 players against qualifiers.

Moneyline vs spread — when does each make sense?

The moneyline pays based on win probability; the spread is a coin-flip line where the favorite has to win by enough. Moneylines are usually better when you think a favorite wins outright but doesn't cover, or when you like a big underdog to pull off the upset. Spreads are usually better for picking close games where you have a small edge on the margin.

For combining moneylines into a parlay, see the parlay calculator or the round robin parlay calculator.
