Is a blackjack tournament worth the entry fee? Type in what the flyer says and what the tournament desk tells you. You get the expected value of one entry, whether the casino is adding money (an overlay) or keeping some, and how good you have to be to come out ahead.

If the entrants play about equally well, every seat has the same chance at every prize, so each seat’s expected share is prize pool ÷ entrants. That is true however the prizes are split: winner-take-all and a flat payout to the top ten have the same average. The split changes how often you cash and how big the cash is, which is the last two rows.
The default numbers are a $10,000 guaranteed pool, 40 entrants, $200 entry. Each seat is worth $250, so an average player is $50 ahead before the first hand. The break-even field is pool ÷ cost, 50 entrants. At 60 entrants the seat is worth $167, the same player is $33 behind, and they need to win 1.2× an average share to get the fee back.
Many tournaments pay back a percentage of what comes in instead of a fixed guarantee. Then the pool grows with the field, and the average seat is worth exactly that percentage of what you paid. At 100% the average player breaks even at any field size. At 80% the casino keeps $20 of every $100, and you need a 1.25× edge just to get even. If a flyer has both, a guarantee and a percentage, the pool is whichever is bigger, and that is what the calculator uses.
A rebuy adds money to the pool and to your cost at the same time. The calculator assumes you rebuy as often as the average entrant. If rebuys are paid back 100%, they don’t change the average player’s EV. Where a guarantee is doing the work, they make it worse: a $10,000 guarantee with 40 entrants and one $100 rebuy each costs you $300 for the same $250 seat. A rebuy can only raise an average player’s EV if more than 100% of it goes into the pool.
1 means you win the average share. 1.5 means you win half again as much, over many tournaments. Nobody knows their number exactly. The useful row is edge you need to break even: if it says 1.25, ask whether you really outplay three out of four people at the table. Skill in blackjack tournaments is concentrated in the last few hands, which is what Final Hand drills and the bet sizer calculates. The strategy guide explains why.
The average share is exact for a field of equal players. Taxes on large prizes, tipping the dealers, and travel are left out. Count anything else you get with the entry at what you would actually pay for it, not the posted room rate. Strategy and education only. Nothing here guarantees a win.
