Bonus Wagering Math: How to Calculate What a Welcome Offer Really Costs
A wagering requirement turns a headline bonus figure into a target you have to hit before any of it — or the winnings it generates — can be withdrawn. The number attached to it, usually written as a multiplier like "25x," means little on its own until you know exactly what it multiplies. Once you can run that calculation in your head, comparing two offers stops being guesswork.
Step One: Find the Base the Multiplier Applies To
Operators calculate wagering requirements against one of two bases, and the difference is significant. Bonus-only wagering multiplies just the bonus amount. Deposit-plus-bonus wagering multiplies the combined total of what you put in and what you were given. Take a $40 bonus at 25x: on a bonus-only basis, that's $1,000 in required wagers. If the same 25x applies to a $40 deposit plus the $40 bonus, the requirement jumps to $2,000 — double the play for what reads as an identical "25x" on the banner. The base is usually one sentence in the terms; find that sentence before doing anything else.
Step Two: Do the Multiplication
Once you know the base, the arithmetic is simple: base amount × wagering multiplier = total wagers required. A $60 bonus at 30x bonus-only wagering needs $1,800 in qualifying bets before a withdrawal is possible. Write that number down before comparing it to anything else, including the size of the bonus itself — a large bonus with an unrealistic wagering total is not automatically better than a smaller one you can actually clear.
Step Three: Check What Counts, and How Much
Not every wager counts equally toward the total. Slots commonly contribute 100% of each bet. Live dealer tables, table games and video poker frequently count for far less — a common range is 10% to 50%, and some titles are excluded from wagering entirely. If roulette counts at 10%, a $20 bet only clears $2 of the requirement, meaning a player planning to wager it off at the tables needs roughly ten times the raw bet volume that a slots-only calculation would suggest. This contribution table almost always sits on a separate page from the headline bonus terms, so check both.
Step Four: Note the Time Limit and Max-Bet Rule
Two more clauses decide whether the wagering total you calculated is realistic to hit at all. A time limit — typically 7 to 30 days — caps how long you have before the bonus and any related winnings expire. A maximum bet per spin or hand while a bonus is active, often in the $5–$10 CAD range, stops the requirement from being cleared in one large wager; exceeding it can void the bonus even if the total wagering figure was otherwise met. Build both into your plan before you start playing, not after the clock has already been running for a week.
A Five-Minute Pre-Claim Checklist
- Find the base: bonus-only, or deposit plus bonus
- Multiply the base by the wagering requirement for the total dollar figure
- Check the contribution percentage for the games you plan to play
- Note the time limit and the maximum bet allowed while the bonus is active
- Compare the final wagering total to your normal play volume — not to the size of the headline bonus
Applying the Math to Billybets' Welcome Package
Billybets advertises a welcome offer of 100% up to $750 plus 200 free spins, and — like most operators — does not publish the wagering multiplier on the homepage banner itself; that figure sits in the bonus terms rather than the promotional page. Before running the calculation above on this specific offer, the Billybets bonus page is the place to find the actual base and multiplier, and our Billybets review covers the wider trust picture — licensing, payments and what else is or isn't disclosed upfront — worth reading alongside the terms.
When a Smaller Offer Wins
A large headline number is not automatically the better deal once the multiplication is done. A modest bonus with a low multiplier and full-value contribution on your preferred games can require far less total wagering than an eye-catching figure gated behind a high multiplier and reduced contribution rates. Run the numbers before comparing sizes — the arithmetic takes less time than most bonus banners take to load.
