How we do the math

Bonus you get = min(deposit x match%, max cap). Total wagering = (bonus or bonus+deposit) x multiplier / game weighting. Expected house take = wagering x (1 - RTP). Net EV = bonus - expected house take.

Benchmarks: a bonus-only 25x or lower is excellent; 30-35x is market median; 40x+ is a flag. Add one notch of pain for deposit+bonus wagering. Live casino and roulette weightings turn almost any headline into a trap.

The clearing time estimate assumes 20 spins per minute at the max bet you entered. It is not advice; it is the math the terms imply.

Why we built this

The number on the banner is the headline. The number in the terms is the real deal. This calculator strips the marketing out of any bonus and tells you what you can actually expect to keep. If the result says "Avoid", we promise it is not a hint, it is math. If the result says "Excellent", you are looking at one of the roughly one-in-ten offers that pay back more than they cost.

How to use the Metareavr Bonus Calculator

Our bonus calculator is designed to answer the one question every player should be asking before claiming an offer: what is this bonus actually worth once the wagering rules are honoured? You do not need to memorise probability theory or build a spreadsheet. Enter six simple inputs and the tool returns a hard number and a verdict in under a second.

Step-by-step: the six inputs

  1. Your deposit. Enter the amount of real money you plan to transfer into the casino. Use the currency shown on the operator's cashier page. The calculator treats this as the cash that unlocks the bonus.
  2. Match percentage. The headline figure the casino advertises. A 100% match doubles your deposit; a 200% match triples it. Type the percentage shown in the promotion banner.
  3. Bonus cap. Almost every bonus is capped at a maximum payout. If the offer says "100% up to 500", enter 500 here. This prevents the calculator from inflating the figure beyond what the operator will actually credit.
  4. Wagering requirement. The multiplier you must wager before the balance converts to withdrawable cash. Common values are 30x, 35x, 40x. Some promotions apply the wagering to the bonus alone (B), others to deposit plus bonus (D+B). Select whichever the terms specify.
  5. Game RTP. The Return to Player percentage of the slot or table game you plan to clear the wagering on. Modern slots run between 92% and 98%. If you do not know the RTP, leave the default 96%, which matches the average catalogue.
  6. Max bet while wagering. Most bonus terms cap the stake you can place during the clearing period, typically between 5 and 10 per spin. Enter the exact figure from the terms so the calculator can estimate how long the wagering will take.

Reading the result

Once you press calculate, four numbers appear. The first is the expected value, which is the mathematical average of what the bonus returns net of wagering losses. A positive number means the offer pays more than it costs you in theoretical house edge; a negative number means the bonus is a slow drain on your deposit. The second is the total wagering amount in your currency, which is the volume of bets you need to place to clear the requirement. The third is the estimated clearing time, calculated from your max-bet cap and an industry-standard 500 spins per hour. The fourth is the Metareavr verdict label (Excellent, Decent, Marginal, or Avoid) that summarises the first three numbers in one word.

Why this calculator matters

Casino marketing teams design bonus banners to make an offer look generous. A "300% up to 3000" headline is impressive until you discover the 50x wagering, the 5 max bet cap and the 92% RTP slot list tied to it. On paper the promotion gifts you 3000 in play money. Mathematically, by the time you have met the wagering, the house has reclaimed most of it. The Metareavr calculator does the arithmetic the small print tries to hide and tells you the honest value in two seconds.

Benefits of using the Metareavr calculator

Practical tips for better results

Always enter the exact figures from the terms and conditions, not from the promotional banner. The banner shows the best case; the terms show reality. If a bonus applies wagering on deposit plus bonus (D+B), the requirement is double what a bonus-only (B) offer demands for the same multiplier, so select the right mode. If you plan to clear the bonus on blackjack or video poker rather than slots, remember most casinos count table games at only 10% or even 0% toward wagering; the calculator defaults to slots because that is where 90% of bonuses are actually played, but you should check the game contribution table before depositing. Finally, if the verdict comes back "Marginal" or "Avoid", it is almost always cheaper to deposit without the bonus and play with cash that has no wagering strings attached.

When the calculator cannot help

A few promotions sit outside the wagering-requirement model. Free spins with no wagering on winnings are a direct cash gift and do not need calculating. Cashback offers refund a percentage of losses rather than top up your balance; use the match-percentage input at 0% and add your refund rate as an informal boost. Tournament leaderboards and missions depend on your rank versus other players and cannot be reduced to a single figure. For every other bonus type, from classic welcome packs to high-roller reloads, the calculator gives you the honest number the fine print does not.
