Break-even win rate calculator
Minimum win % needed to be profitable at given odds
Calculate the minimum win percentage you need at given odds to break even — and what win rate you need to actually profit.
What is break-even win rate?
Every odds price has a break-even win rate — the percentage of bets you need to win just to recoup your stakes. At 2.00 odds you need 50%. At 1.91 (the classic -110 American line) you need 52.4%. At 1.50 you need 66.7%. Most amateur bettors don't realize how high this bar is — that's why they lose. Use Value Bet finder to identify markets where the bookmaker's break-even is lower than your true win rate, and No-vig calculator to see what 'fair' break-even would be without margin.

How to use
- 1Enter the average odds you bet at.
- 2Optionally enter your actual win rate to see your edge or deficit.
- 3See the breakeven percentage and the win rate needed for 5%, 10% and 20% ROI.
Example: -110 American (1.91 decimal)
At 1.91 odds, break-even = 100/1.91 = 52.4%. If you hit 53%: tiny profit. If you hit 55%: a strong ~5% ROI. If you hit 60%: rare and elite ~15% ROI. Most published tipsters average 53-55%, despite claims of 60%+ — track CLV via our CLV calculator instead of raw win rate.
When to use
- Reality-check tipster claims (60%+ at short odds is statistically rare)
- Set realistic personal targets
- Compare required hit rates across different odds ranges
