Bonus Wagering & Value Calculator

A casino bonus can look generous on the banner and still cost you money once the wagering requirement is attached. This free calculator does the maths for you: enter the deposit, match percentage, maximum bonus and wagering multiple, pick the game you intend to play, and the simulation plays your scenario through to the end thousands of times.

The result is an honest read on expected value — whether, on average, claiming the bonus leaves you ahead or behind versus simply playing with your own cash. It also shows how often players in your exact position actually finish the wagering, because a bonus you almost never clear is worth far less than its face value suggests.

Three numbers matter most. The expected value (EV) is your average outcome across thousands of simulated runs — positive means the offer is, on balance, worth claiming; negative means it costs you more than it gives. The chance of clearing tells you how often the wagering is actually completed before the balance runs out, so an EV that depends on a 12% clearance is fragile. The range of outcomes shows the spread between a typical bad run and a typical good run — the wider it is, the more variance you are taking on, even when the average looks fine. Read all three together, never just the EV in isolation.

What the wagering requirement really costs

The wagering requirement is the number of times you must bet the bonus (and sometimes the deposit too) before any winnings can be withdrawn. A ₹5,000 bonus at 40x wagering means ₹2,00,000 of turnover. Every rupee of that turnover is exposed to the house edge, so the longer you have to play, the more the maths quietly erodes the bonus.

This is why a 200% match at 50x can be worth less than a 100% match at 20x. The headline percentage is marketing; the wagering multiple is the price. Our calculator collapses both into a single expected-value figure so you can compare offers fairly, the way you would compare two interest rates rather than two advertisements.

Always check whether wagering is on the bonus only or on deposit plus bonus — the latter roughly doubles the turnover and can turn a fair offer into a poor one. The advanced settings let you set this exactly as written in the terms and conditions.

Why the game you choose changes everything

Not every game counts equally toward wagering. Slots usually contribute 100%, while table games like blackjack and roulette often count for just 5–10%, or are excluded entirely. A low-edge game that only contributes 10% can take ten times as long to clear, exposing you to far more turnover and a worse expected value despite its friendlier RTP.

Volatility matters just as much as contribution. A high-volatility slot gives you a small chance of clearing the wagering in one big swing and a large chance of busting early — so the average can look acceptable while most individual sessions end badly. The calculator captures this by simulating thousands of full play-throughs rather than assuming a smooth, average game.

Use the game selector and the contribution field together. Set them to match the offer's terms precisely, and the EV you see will reflect the offer you are actually being given — not an idealised version of it.

How games count toward wagering

Casinos weight games differently when clearing a bonus — slots usually count fully, while lower-edge games count for little or nothing, as shown below.

Bonus types explained

• Cashable: Both the bonus and any winnings can be withdrawn once you have met the wagering requirement.
• Sticky: The bonus itself can never be withdrawn — only the winnings made with it — and it is removed from your balance when you cash out.
• Free spins: A set number of slot spins at a fixed value; the winnings are usually credited as bonus funds that carry their own wagering requirement.
• Cashback: A percentage of your net losses returned over a period, often with low or no wagering — generally the most player-friendly offer type.

A worked example: ₹2,000 deposit, 100% match, 35x

Suppose you deposit ₹2,000 and claim a 100% match up to ₹2,000, so you receive a ₹2,000 bonus and start with ₹4,000. The wagering is 35x the bonus, which is ₹2,000 × 35 = ₹70,000 of turnover, played on a slot with 96% RTP that contributes 100%.

Across ₹70,000 of turnover at a 4% house edge, the expected cost of clearing is roughly ₹2,800. Since the bonus itself is only ₹2,000, the simulation returns a negative expected value of about −₹600, and a chance of clearing near 41% — most runs bust before the turnover is met. The typical good run finishes around +₹1,500, the typical bad run around −₹2,000.

The verdict: borderline-to-poor value as written. Drop the wagering to 20x, or raise the RTP to 97%, and the same calculator flips the EV positive — which is exactly the kind of comparison it exists to make.

Glossary of key terms

RTP

Return to Player — the percentage of all staked money a game pays back on average over the very long run; a 96% RTP means ₹96 returned per ₹100 staked across millions of spins.

House edge

The mathematical advantage the casino holds, equal to 100% minus the RTP; it applies to your total turnover, which is why long sessions cost more on average.

Volatility

How widely a game's results swing around its average — high volatility means rare big wins and many losing rounds, low volatility means small, frequent payouts.

Wagering requirement

The number of times you must bet a bonus (and sometimes your deposit) before winnings can be withdrawn, written as a multiple such as 35x.

Expected value (EV)

Your average outcome across thousands of simulated runs; positive EV means a scenario favours you on balance, negative means it costs you over time — never a guarantee for one session.
