Bonus Wagering Calculator

Use this bonus wagering calculator to understand a requirement written in casino terms. Choose the wagering base, enter its multiplier, account for credited progress and apply the game’s contribution rate. The result separates required qualifying credit from the raw amount that would need to be wagered under the entered assumptions.

This is an educational terms calculator, using hypothetical Canadian-dollar examples. It does not list offers, provide codes or determine whether an account is eligible. A calculated zero remaining requirement is not the same as a confirmed withdrawable balance.

Calculate a wagering requirement

Copy the definitions from the actual terms. “Already credited wagering” means progress after any contribution adjustment, not a deposit, current balance or unweighted stake total. The maximum-stake field is optional; leaving it blank means no stake limit has been checked.

Read casino bonus terms for balance treatment, expiry, conversion and withdrawal conditions. This tool checks the arithmetic once the relevant definitions have been identified; it does not replace those definitions.

How to enter the terms correctly

Find the exact amount to which the multiplier applies.
Choose bonus only, deposit plus bonus, or a custom base.
Enter the multiplier as a number: a written 10× becomes 10.
Enter progress already credited by the account’s wagering counter, if any.
Enter the exact game’s contribution percentage.
Enter a stake for the whole-wager illustration and, if known, the applicable maximum.
Select Calculate wagering and keep the assumptions beside the result.

The form disables amount fields that do not belong to the selected base. A deposit entered under deposit-plus-bonus mode therefore does not silently affect bonus-only mode. Changing an input replaces the old answer with a recalculation reminder, while Reset calculator restores the same starting example each time.

Choose the amount being multiplied

Bonus only

The target is the bonus amount multiplied by the requirement. The deposit is not added merely because it appears in the account.

Deposit plus bonus

The target is the sum of the entered deposit and bonus, multiplied by the requirement. Both amounts belong to the defined base.

Custom base

Use an explicitly defined amount such as eligible credited winnings. Enter that amount itself rather than a spin count or an estimated prize.

For example, a hypothetical $50 base at 10× produces $500 of required credited wagering. If the terms instead define a $100 deposit plus that $50 amount as the base, the same multiplier produces $1,500. The difference is the base, even though the written multiplier is unchanged.

Do not infer the base from a short heading. Locate the definition in the full terms and check any document that takes priority. OLG’s general terms, for instance, distinguish their general conditions from promotion-specific terms. That illustrates why a calculator needs the actual definition rather than a label alone.

The calculation in four steps

Required credited wagering = defined base × multiplier. Next subtract the progress already credited, with the remaining amount capped at zero. Finally divide the remaining credit by the contribution rate expressed as a fraction to find the raw wagering needed under the model.

For a hypothetical $50 bonus-only base at 10×, the target is $500. If the account has already credited $100 of qualifying wagering, $400 remains. At a contribution of 20%, the raw wagering illustration is $400 ÷ 0.20 = $2,000.

Each $1 wager in that model adds twenty cents of credit, so 2,000 fully qualifying $1 wagers supply the remaining $400. The tool rounds the wager count up rather than pretending that part of a wager can be placed. This is a calculation of the stated conditions, not a probability of completing them.

Worked wagering examples

Hypothetical requirements with no operator offer attached
Base and multiplier	Already credited	Contribution	Remaining credit	Raw wagering
$50 bonus only × 10	$0	100%	$500	$500
($100 + $50) × 10	$0	100%	$1,500	$1,500
$50 bonus only × 10	$100	20%	$400	$2,000
$12.50 custom base × 8	$40	50%	$60	$120
$50 bonus only × 10	$500	0%	$0	$0 remains
$50 bonus only × 10	$100	0%	$400	No progress at this rate

Compare one column at a time. The two zero-contribution rows have different results because one target is already satisfied numerically and the other is not. Neither row establishes eligibility, a payout or permission to use a particular game.

Contribution is not RTP or house edge

A contribution percentage describes how much of a qualifying stake is credited toward a requirement. It is a term-defined progress weight. RTP describes a theoretical return under a game model, while house edge describes a mathematical disadvantage on a stated wager basis. These percentages answer different questions.

At 25% contribution, a hypothetical $4 qualifying wager adds $1 of progress before any account-specific rounding. A game with the same RTP could have a different contribution, and a game with a different RTP could share that contribution. Do not substitute a return percentage for the weighting in the form.

The House Edge Calculator uses its own stated blackjack profiles and original-wager basis. Its result should not be pasted into the contribution box. Our RTP guide explains the separate return measure.

Enter credited progress rather than raw stakes

If an account has recorded $200 of stakes on a game contributing 25%, the associated progress would be $50 under the simple fixed-rate model. Enter $50 as already credited wagering. Entering $200 would subtract four times as much progress as the example earned.

The reverse mistake is to take an already weighted $50 counter and apply the 25% adjustment again, reducing it to $12.50. The progress input is already on the credited basis. This tool applies contribution only when converting the remaining credited target into an illustration of future raw wagering.

Read the counter’s units before copying it. A screen labelled amount remaining may already show the figure you want to calculate. A screen labelled total wagered might describe unweighted stakes instead. If its definition is unclear, a calculation cannot resolve that missing account information.

When the account shows only an amount remaining

If the account clearly defines its counter as credited wagering still required, that figure already represents the result of subtracting completed progress. Do not treat it as the original bonus and multiply it by the original requirement again. First confirm whether it is credited progress remaining or raw wagering remaining.

For a hypothetical counter of $250 credited wagering remaining, custom mode can illustrate that known remainder by using a $250 custom amount, a multiplier of 1 and zero already credited. At 25% contribution the raw-wagering calculation is $250 ÷ 0.25 = $1,000. Label the saved note “remaining credited counter,” because this input is not the original award.

Using 10 as the multiplier on that already remaining $250 would create a new $2,500 credited target. It would answer a different question and exaggerate this example’s remainder tenfold. Likewise, entering an additional completed-progress amount would subtract progress a second time.

If the counter instead says $250 of raw wagering remains for a particular game, applying the contribution division again could also overstate the task. The same visible currency symbol can label different measures. Keep the counter’s definition, the selected game and the relevant rate together before attempting to reproduce it.

What zero contribution means

When a positive credited amount remains and the entered rate is 0%, the selected wager earns no progress in this model. There is no finite raw-wagering total that closes the remaining requirement at that rate. The calculator displays that result without dividing by zero.

Zero contribution does not tell you whether the game is permitted. A term can distinguish between an excluded game and an allowed game that earns no progress. The calculator has no eligibility list and does not treat a zero entered rate as permission to play.

If the entered progress already equals or exceeds the target, remaining wagering is zero even with contribution set to zero. That is simply subtraction. The output still states that the calculation does not confirm withdrawable funds, because the account can have other conditions.

Understand the whole-wager count

The count divides the remaining credited requirement by the credit supplied by one entered stake, then rounds up. It assumes the same stake, contribution and full eligibility on every counted wager. It does not model a sequence of wins and losses or whether the available balance can fund the sequence.

Suppose $5 of credit remains, contribution is 30% and each qualifying wager is $2. Each supplies $0.60 of credit. Eight wagers supply $4.80, which is insufficient; nine supply $5.40. The output therefore shows nine whole wagers, while the raw-wagering lower bound is $16.67 after rounding up to cents.

Nine $2 wagers total $18, so the count and the cent-rounded raw figure need not describe exactly the same amount. One is a lower bound at cent precision; the other respects the chosen whole stake. The difference is explained by rounding rather than an extra requirement.

The optional maximum-stake check

If you enter a maximum from the terms, the form compares the proposed stake with that number. A stake above the entered limit produces an error and clears the result. A stake equal to the entered limit passes this numerical check; it does not validate the rest of the terms.

For example, entering a $2 stake and a $1.50 maximum fails. Entering a $1.50 stake and $1.50 maximum does not exceed the stated amount. Leaving the maximum blank produces an explicit “not checked” message rather than assuming there is no restriction.

Check what the maximum applies to: a wager, a round, a transaction or a feature purchase can be different units. The tool checks the number supplied, not the interpretation of a game’s controls. Our game rules guide discusses the importance of using the correct game and transaction definitions.

Mixed games and changing contribution rates

If a record includes different rates, calculate each segment’s credited progress separately. In a hypothetical record, $100 of qualifying stakes at 100% adds $100 of credit, and $200 at 20% adds $40. Their combined credit is $140, not $300 and not a simple average of the percentages.

Enter $140 as already credited wagering, then use the applicable rate for the next fixed-rate illustration. This preserves what has already been earned without pretending the whole record used one game. It also avoids weighting the same historical progress twice.

Some systems distinguish between the cash-funded and restricted-funded portions of a wager. If only part of a stake is eligible for a particular counter, a game contribution percentage alone may not describe it. This form assumes fully qualifying stakes and cannot infer funding allocation from a combined balance.

Fractional multipliers and credit rounding

The inputs accept up to two decimal places for amounts, the multiplier and the contribution percentage. The calculator keeps the credit arithmetic in integer units small enough to represent these products exactly. It does not repeatedly round each intermediate multiplication to cents.

A hypothetical $0.01 base at 0.50× creates a $0.005 credited target. The output preserves that fraction rather than displaying it as a zero target. At 100% contribution, the raw amount rounds up to $0.01 because the form illustrates raw wagering in cents.

An operator may round progress after each transaction, apply a minimum qualifying stake or use another counter precision. Those rules can change an account’s displayed progress. The form states its no-per-wager-rounding assumption so its result can be compared with the account’s actual method.

Changing the base or weighting changes the workload

Hypothetical $50 base with no progress already credited
Multiplier	Required credit	At 100% contribution	At 50% contribution	At 10% contribution
2×	$100	$100 raw	$200 raw	$1,000 raw
5×	$250	$250 raw	$500 raw	$2,500 raw
10×	$500	$500 raw	$1,000 raw	$5,000 raw

The table illustrates multiplication and division, not an offer comparison or a suggestion to pursue a particular target. A smaller written multiplier cannot be interpreted in isolation from its base, contribution rules and other restrictions.

Zero remaining is not a withdrawal amount

When credited progress reaches the calculated target, the remaining figure becomes zero. It does not calculate the account balance, distinguish deposited money from restricted credit or determine how those balances convert. It also does not establish whether a previous transaction complied with the terms.

Any withdrawal question needs the applicable conversion treatment, remaining funds, account verification and cashier conditions. The withdrawals guide and account verification guide cover those separate account steps.

If entered progress is greater than the calculated target, the tool caps the remaining amount at zero and reports the excess. It does not create negative wagering, additional cash or an automatic refund. Check whether the counter and the base came from the same requirement before relying on the comparison.

Expiry and balance are outside the arithmetic

The form has no expiry clock because a deadline and a theoretical wager count do not establish that the requirement can or should be completed. Dates can involve activation, use, completion and conversion stages, sometimes with a stated time zone. Read each condition separately.

Likewise, a remaining balance is not a promise that the calculated raw wagering can be funded. Losses can end play before the counter reaches its target. The tool does not simulate that path, calculate a completion probability or tell you to add funds to continue.

Keep personal limits separate from the progress counter. A mathematical target is not a reason to increase a stake or continue after a planned stopping point. The site’s responsible gambling page covers limit-setting and relevant support information.

Do not turn wagering into a profit forecast

A $500 raw-wagering result does not mean a $500 loss, a $500 bankroll or a $500 withdrawal. It describes the sum of qualifying stakes under the selected contribution model. Money can be reused as wagers return, but the calculator does not track that changing balance.

Multiplying a bonus amount by a requirement is also not a calculation of its cash value. Net outcomes depend on the games, stakes, settlement sequence, restrictions and remaining balance. A simple subtraction of one expected cost from a headline amount would omit conditions this form does not model.

Use the session-balance calculator for a separate accounting record, and the odds and house-edge guide to distinguish expectation from a particular result. Neither measure substitutes for the terms governing restricted funds.

Check an unexpected result

Start with the base selector. A deposit-plus-bonus calculation will be larger than a bonus-only calculation when the entered deposit is positive. Then check the multiplier, ensuring that 10× was entered as 10 rather than 0.10 or 1,000.

Next check percentage notation. A 20% contribution belongs in the box as 20, not 0.20. In this form, 0.20 means one fifth of one percent and creates a very different raw-wagering illustration. The printed rate in the output helps reveal that mistake.

Finally check the progress units, the stake limit and whether the result was recalculated after changing a field. The model accepts zero amounts and a zero multiplier for arithmetic completeness, but a zero numeric target does not prove that an account has no other conditions.

Input limits and unsupported notation

Deposit, bonus, custom base, stake and optional maximum fields accept up to $1,000,000. Already credited wagering accepts up to $2,000,000,000 to cover the largest supported combined-base example. The multiplier accepts zero through 1,000, and contribution accepts zero through 100%.

Use ordinary decimal notation without a currency symbol, thousands separator or exponent. Enter fifty cents as 0.50, not .50. A stake must be positive, and an entered maximum must also be positive. These limits define the calculator’s arithmetic range; they do not describe an operator’s limits or make an entered requirement a currently available offer.

Keep a reproducible terms record

Save the exact base definition, the amount, multiplier, contribution rate, credited progress, stake unit and any maximum used. Also record the relevant term version and the date the account information was read. A bare note saying “10×” cannot reproduce the result.

For a screenshot, include the selected base and the output. For mixed-game histories, retain the segment calculations that produced the already credited amount. If an essential definition is unknown, identify it as unknown rather than choosing a convenient assumption.

Bonus wagering calculator questions

What is the difference between bonus-only and deposit-plus-bonus wagering?

The selected base determines which amount is multiplied. A hypothetical $50 bonus at 10× gives a $500 credited target. If the terms instead apply 10× to a $100 deposit plus that $50 bonus, the target is $1,500. The same multiplier can therefore describe different requirements.

What should I enter as already credited wagering?

Enter progress after contribution weighting, using the account counter’s definition. Under a simple 25% contribution model, $200 of qualifying stakes earns $50 of credit, so enter $50. Do not enter a deposit, account balance or unweighted stakes, and do not apply the weighting to an already credited counter again.

Is game contribution the same as RTP?

No. Contribution specifies how much of a qualifying wager counts toward the stated requirement. RTP describes theoretical game return. A hypothetical $4 wager at 25% contribution adds $1 of progress before any account-specific rounding. Neither that rate nor the remaining target predicts the outcome of the wager.

What happens when contribution is zero?

If a positive credited amount remains, 0% contribution earns no further progress and the calculator displays no finite completion amount at that rate. If entered progress already meets the target, the remaining amount is zero. A zero contribution entry does not establish whether the game is permitted by the terms.

Why can the whole-wager amount exceed the raw-wagering figure?

The raw figure rounds the minimum amount up to cents, while the count uses whole wagers of the entered size. With $5 of credit remaining, 30% contribution and a $2 stake, the raw figure is $16.67. Nine whole $2 wagers total $18 and supply $5.40 of credit under the model.

Can I use a remaining-wagering counter as the custom amount?

Only after confirming its units. For $250 of credited wagering remaining, enter a $250 custom amount, multiplier 1 and zero already credited. At 25% contribution that represents $1,000 raw wagering. A counter already expressed as raw wagering should not be divided by contribution a second time.

Does the maximum-stake check verify all the terms?

No. It compares the entered stake with an optional entered maximum. Above the maximum produces an error; equal to it passes that numerical check. A blank maximum means no limit was checked. Game eligibility, transaction definitions, balance restrictions and other conditions remain outside this comparison.

Does zero remaining wagering mean my balance can be withdrawn?

No. It means the entered credited progress meets the calculated numerical target. The calculator does not read the balance, check expiry or eligibility, confirm compliance, convert restricted funds or verify a withdrawal. Progress above the target is capped at zero remaining; it does not create extra money.

Does this calculator connect to a casino account?

No. It calculates in the page from the figures you enter. It cannot read a cashier, update a progress counter, accept an offer or place a wager. Its model uses a fixed contribution rate, fully qualifying stakes and no per-wager credit rounding. Changing an input requires a fresh calculation.
