Wagering Requirement Calculator

How this calculator works

The engine behind this tool is one short formula with a couple of guardrails. First it works out the total wager: that is the bonus amount multiplied by the wager multiplier, or, for a "deposit plus bonus" structure, the combined deposit and bonus multiplied by the multiplier. A 35x wager on a 100 EUR bonus-only offer is 3,500 EUR of turnover. The same multiplier on a 100 EUR deposit plus 100 EUR bonus is 7,000 EUR, which is why the deposit plus bonus clause often tells you more about the offer than the headline figure.

Next the tool adjusts for game contribution. The industry phrase sounds like it should shrink the number, but it does the opposite: if blackjack contributes 10 percent to wagering, every 10 EUR you bet only counts as 1 EUR toward the requirement. To clear the same 3,500 EUR wager at 10 percent contribution, you need 35,000 EUR of raw turnover, which is ten times more spins or hands.

The spin count and hour count are then driven by two realistic session numbers. Spins per hour is how fast you actually push the spin button, including waiting for autoplay animations and bonus rounds. Slots sit between 500 and 800 spins per hour, blackjack hands land between 60 and 100 per hour, live roulette rarely clears 40 spins per hour. Hours per day is just how long you will realistically sit down each session, and days to clear is the first number that tends to shock players.

Finally the expiry check compares the days to clear with the operator window. Most bonus expiries sit at 7, 14, 21 or 30 days from acceptance, and the pill flips red the moment your pace cannot catch up. This is the single most ignored field in bonus terms, and it is why so many bonuses expire with wagering half done.

Two notes on the maths. Spins per hour below one, bets below one cent, or a zero game contribution are treated as placeholders and the result cells show a hyphen rather than infinity. The formula also assumes you keep betting at the same average spin size throughout, which is usually a safe assumption inside the max-bet cap operators enforce during wagering.

One extra thing worth saying out loud. The hours figure is play time, not real time. Toilet breaks, dinner, a quick email check, all of it drops the real spin count. In practice a "two-hour session" is closer to 70 minutes of actual spin time, which means a 7-hour clear usually takes closer to 10 real hours spread over several evenings. Build that buffer into your expiry maths and the bonus either clears cleanly or you drop it before you deposit.

Worked examples

Three realistic scenarios, run through the same formula the live panel uses. Numbers are rounded for the table.

The pattern is consistent. Deposit plus bonus structures and anything below 50 percent contribution almost always need an expiry window longer than 7 days to actually clear.

Scenario 1 is the one most reviewers quote because it fits the format of a weekend session. Scenario 2 is what quietly happens to table-game regulars who assume a bonus is a bonus. Scenario 3 is the welcome-package maths that explains why so many first deposits end in a void: the headline number is 200 EUR, but the wager that actually needs clearing is 8,000 EUR of qualifying turnover, which jumps to 16,000 EUR of raw play once the 50 percent contribution is baked in.

A simple rule falls out of these numbers: if you cannot clear the bonus inside half the expiry window at your realistic pace, pick a smaller offer or move to a higher-contribution game. The headroom is what covers the days you miss, the sessions that run shorter than planned, and the bonus rounds that eat clock without eating wager.
