Bonus Summary
How This Calculator Works
Monte Carlo Simulation
We simulate 50,000 complete bonus sessions, each starting with your deposit + bonus and placing bets until either the wagering requirement is met or you go bust. The results show what happens on average.
Why Wagering Matters
A ₹1,000 bonus with 10x wagering requires ₹10,000 in total bets. With accumulator requirements, your effective win rate drops significantly.
Singles vs Accumulators
Singles are easier to clear - you win ~50% of bets at fair odds. Accumulators with 3+ legs at 1.40 odds each have only ~35% win rate - much harder to profit.
Time Limits & Win Caps
Strict time limits (like Parimatch's 3 days) can cause you to forfeit the bonus. Win caps limit your upside even if you get lucky. Both significantly reduce expected value.
Frequently Asked Questions
Frequently Asked Questions
What is a wagering requirement?
A wagering requirement (also called rollover) is how many times you must bet the bonus before withdrawal. Example: ₹1,000 bonus with 10x wagering = ₹10,000 in total bets required.
How does the Monte Carlo simulation work?
We run 50,000 simulated sessions. Each starts with deposit + bonus, places bets until wagering is complete or bust. The Expected Value is the average profit/loss across all runs.
Why are accumulator bonuses harder to clear?
Accumulators require all legs to win. A 3-leg acca at 1.50 odds has only ~30% win rate, compared to ~67% for singles. This increases bust rate dramatically.
What does 'bust rate' mean?
Bust rate = percentage of simulations where you lost everything before completing wagering. A 40% bust rate means 4 out of 10 players lose their entire bankroll.
Should I always take a bonus with positive EV?
Not always. Consider bust rate and time required. A +₹200 EV bonus with 60% bust rate and 30 hours wagering may not be worth it. Check if you can withdraw your deposit without the bonus.
Why do sports bonuses have lower wagering than casino?
Sports has ~5% house edge vs slots at ~4% (but higher variance). Bookmakers compensate with min odds requirements (1.40+), accumulator-only rules, and strict time limits.
