Break-even win rate at +200

The implied probability of +200 is about 33.33% (1 ÷ the exact decimal odds, shown rounded). That is the break-even win rate: if you bet this price many times on win-or-lose bets, you need to win more often than that to come out ahead. Whether a +200 bet is good value depends only on whether your honest estimate of the chance beats that number — the EV calculator does the comparison.

+200 in a parlay

Two +200 legs parlayed combine to decimal odds of 9.00 (+800): a $100 two-leg parlay pays $900.00 if both win. Three legs: decimal 27.00 (+2600), paying $2,700.00 on $100. For independent selections from different events, those prices imply a break-even chance of about 3.70% for all three winning — an implied figure that includes each price’s margin, not a forecast; bookmakers may refuse or reprice related selections. Payouts use the exact, unrounded combined odds. Build your own with the parlay calculator.

Does +200 mean underdog?

Usually, but not by definition. +200 is odds-against: the profit is more than the stake and the price implies under 50%. Who is the favorite depends on the other prices in the market — in a three-way soccer market (home, draw, away) the favorite can be priced odds-against too.
