What does -200 mean on a moneyline bet?
That's the favorite. A -200 line means you wager $200 to profit $100 — total payout $300. The implied win probability is roughly 67%. Short odds, modest returns. Check out how American moneyline odds actually work if you want the full breakdown on reading favorite and underdog prices.
How much do I win if I bet $100 on +150?
You profit $150 and collect $250 total (profit plus your original stake back). Positive odds always mean the profit is larger than the stake. Plug any amount into the moneyline bet calculator and it does the math instantly.
How do I calculate a moneyline payout by hand?
Two simple formulas. For underdogs (positive odds): (Odds ÷ 100) × Stake. For favorites (negative odds): (100 ÷ |Odds|) × Stake. Add the stake back to get total payout. Example: $50 at +180 = ($50 × 180) ÷ 100 = $90 profit, $140 total. See the moneyline payout formula guide for worked examples across bet sizes.
What is implied probability and why does it matter?
Implied probability is the win percentage the posted odds mathematically suggest. +150 implies roughly 40%; -200 implies roughly 67%. If your own assessment of a team's chances is higher than the implied number, you may have a value bet. Lower and you're paying for false confidence. Implied probability: what your moneyline odds really say goes deeper on how to use this number.
Do I owe taxes on winnings under $600?
Yes. Every dollar of gambling income is taxable, full stop. The $600 W-2G threshold only triggers a reporting form from the sportsbook — it doesn't create a minimum below which you're exempt. Even a $50 NFL win goes on Form 1040. IRS Topic 419 spells this out. For the new 2026 W-2G threshold change (rising to $2,000), read moneyline winnings and the 2026 W-2G rule change explained.
What is a pick 'em (PK) moneyline?
When both teams are considered evenly matched, the book sets odds near +100/−100 — sometimes shaded to -105 or -110 to build in the vig. Neither side is a true favorite. The vig guide explains why the combined implied probabilities always exceed 100% regardless of the line.
How does a moneyline parlay payout work?
Every leg must win. One loss and the entire parlay loses, regardless of how many other picks were correct. Payouts grow quickly with each added leg, but so does the variance. The moneyline parlay calculator shows multi-leg payouts in seconds.
Which sportsbook has the best moneyline odds?
No single book is always best. FanDuel, DraftKings, BetMGM, Caesars, bet365, and BetRivers each post different numbers on the same game, sometimes varying by a full point or more. Line shopping across books before placing a bet is the simplest edge available to any bettor. More on that at line shopping for moneyline odds across major sportsbooks.

What is the heavy-favorite trap?
Risking $300 to profit $100 at -300 feels safe until the upset hits. The return is so small relative to risk that even a modest losing streak wipes out weeks of wins. Heavy-favorite moneyline bets and why -300 payouts disappoint covers the math behind this common mistake.
What happens if I enter the wrong sign in the calculator?
Big problem. Typing 200 instead of -200 treats a heavy favorite as a massive underdog — the output is completely wrong. Always double-check that negative odds include the minus sign before reading the result. How to use this calculator in under 60 seconds runs through correct input steps.
