A “100% bonus up to 1,000 USDT” sounds like free money. It isn’t: before you can withdraw a bonus, or anything you win with it, you have to bet a multiple of it, and every bet costs you the house edge on average. This guide explains wagering requirements in plain terms, and the calculator shows what a bonus is likely to cost you to clear.
Bonus wagering calculator
Enter the bonus terms. The calculator works out how much you’d have to bet and the average loss along the way, based on the game’s return to player (RTP).
Expected loss is the average over many sessions: total bets × house edge (100% − RTP). Any single session can end far above or below it. It ignores bonus caps, maximum bet rules and winnings limits.
With the default numbers, a $100 bonus at 40× wagering means betting $4,000. At 96% RTP the house keeps 4% of that on average, about $160, which is more than the $100 bonus. That’s typical: at high wagering multiples, most bonuses are worth less than they cost to clear.
The terms that matter
Wagering multiple
How many times you must bet the bonus (or deposit plus bonus) before it becomes withdrawable. 30× to 40× is common at crypto casinos; BitStarz’s welcome package, for example, is 40×. Lower is better. “Wager-free” bonuses have no requirement at all: Winz.io’s welcome prizes are paid this way.
What the multiple applies to
“40× the bonus” and “40× the deposit plus bonus” are very different. On a $100 deposit with a $100 bonus, the first means $4,000 of bets and the second $8,000. Check which one the terms use.
Game contribution
Not every bet counts in full. Slots usually count 100%; table games, live casino and in-house games often count much less, or nothing. At BitStarz, table, live and instant games count 5%, so $1 bet on blackjack clears only 5 cents of wagering. At BetFury, in-house games count 0.2 and slots 1.0. Set the calculator’s “game counts” to see the effect.
Maximum bet
Most bonuses cap your bet size while the bonus is active, often around 4 or 5 USDT. Going over it, even once, can void the bonus and winnings.
Time limit
You may have as little as a day or as long as a few weeks to finish wagering. Short windows push you to bet more, faster.
Winnings caps
Some bonuses limit how much you can withdraw from them. BetFury, for example, caps the conversion of a deposit bonus to your real balance at 1.2 times the bonus.
Is your deposit locked?
Some casinos lock your own deposit until the bonus is wagered, so you can’t withdraw even the money you put in. Others use your real money first and the bonus only after it’s gone. The terms say which.
Sports bonuses usually have their own rules, such as minimum odds per bet; see USDT sports betting.
Rakeback and cashback
Many crypto casinos now offer rakeback (a share of the house edge on your bets returned to you) or cashback (a percentage of losses). These are often paid as real money with no wagering: Cloudbet’s welcome package, for example, is built on rakeback and cash drops. Because they return part of what you lose rather than asking you to bet more, they’re usually simpler to understand. They still reward playing more, so set a budget first.
A quick checklist before accepting
- What’s the multiple, and does it apply to the bonus or deposit plus bonus?
- Which games count, and by how much?
- What’s the maximum bet, and the time limit?
- Is there a cap on winnings or conversion?
- Is my deposit locked until wagering is done?
- Am I in a country excluded from the bonus? Several casinos exclude specific countries from promotions.
