300% Deposit Bonus
A three-hundred-pound bonus on a hundred-pound deposit looks like free money until you price the turnover behind it, which on a typical package at this end of the market runs to five figures before a penny of bonus winnings becomes cash.
The crown-column comparison on this page puts four offers of this sort side by side, each scored by our editors out of five crowns alongside a mark out of ten, with the terms that matter printed as short chips and a call to action in every column. Terms change often, so the operator’s own terms page remains the version to check before you deposit.

How a triple match works
A three hundred percent deposit bonus multiplies your deposit by four in total playing balance: the cash you put in plus three times that sum in bonus funds. Deposit fifty and you play with two hundred. Deposit a hundred and you play with four hundred. The headline sells the second number; the terms govern it. The bonus half of the balance is not yours in the way the deposited half is. It sits under a wagering requirement, a conversion cap and an expiry clock, and any of the three can reduce what you actually take out to a fraction of the advertised figure.
The structure matters as much as the size. Some packages credit the full three hundred percent in one go on a single qualifying deposit. Others split it across a first, second and third deposit, applying separate terms to each tier, and the tier with the largest percentage often carries the strictest multiplier or the smallest cap. Read each tier as its own offer with its own arithmetic. A package that gives one hundred percent on day one and three hundred percent by day three is three separate decisions, not one.
There is also the question of what the percentage applies to. The great majority of offers in this bracket match your deposit, so a three hundred percent deal on a twenty-pound deposit credits sixty pounds of bonus funds. A smaller number phrase the offer against a fixed maximum, for example three hundred percent up to a stated ceiling, and in those cases the match stops at the cap whatever you deposit. Both versions appear in this part of the market; the difference is visible only in the small print, never in the advert.
The turnover assumption
Where the arithmetic below needs a multiplier, the model takes forty times wagering as its working figure, since that is the multiplier this part of the market asks for most often. Offers of this sort print multipliers anywhere from thirty to fifty times, and a few apply the multiplier to the bonus plus the deposit combined, which roughly doubles the true turnover. Because offers at this end of the market revise their terms without notice, the page works from the stated assumption rather than from any one operator’s current print, and it flags where a different multiplier changes the answer.
The table below applies the model to a three hundred percent match at three deposit sizes, assuming the bonus is credited in full, slots contribute one hundred percent towards wagering, and the multiplier applies to bonus funds only. The right-hand column shows the figure where the terms apply the multiplier to the deposit as well, which is the single most expensive sentence hiding in any set of bonus terms.
| Deposit | Bonus credited | Turnover at 40x bonus | Turnover at 40x bonus plus deposit |
|---|---|---|---|
| £50 | £150 | £6,000 | £8,000 |
| £100 | £300 | £12,000 | £16,000 |
| £200 | £600 | £24,000 | £32,000 |
Figures in this table are modelled values, not quotes of any single promotion. They assume a 300% match credited in full, slots weighted at 100%, and the stated multiplier base.
Those sums are the volume of play the terms demand, not a prediction of what you will lose. A twelve-thousand-pound turnover at one-pound stakes is twelve thousand spins of the reels at full weighting. The honest question is whether your bankroll and your patience can carry that volume inside the expiry window, and the honest answer for most readers is that a deposit at the smaller end of the table is the only version worth attempting.
Caps and what the offer pays
The maximum conversion cap is the ceiling on how much bonus winnings can be withdrawn, whatever the account balance shows when wagering finishes. In this bracket caps run from a few hundred pounds to several thousand, and on a three hundred percent package the cap frequently sits below the bonus amount itself. When it does, the offer is a voucher in disguise: the headline promises three hundred pounds of bonus funds on a hundred-pound deposit, but the terms guarantee that no more than the cap can ever leave the account from the bonus side.
The useful comparison is not the headline against the deposit, it is the cap against the turnover. A package with a two-thousand-pound cap and a twelve-thousand-pound turnover asks you to risk volume equal to six times the ceiling, which is a worse ratio than a smaller match with a generous cap and a modest multiplier. This is why the largest percentage in a cashier is not automatically the most valuable. Ratio, not size, is the number that prices the offer.
Caps interact with expiry in a way the adverts never mention. A thirty-day window on a six-figure turnover is a schedule, and missing it forfeits the bonus winnings in full. Some operators void remaining bonus funds and winnings at expiry; others convert what is left at a penalty. The terms will say which, and the sentence is usually one line long.
Which games count
Game weighting decides how much of each stake contributes to the wagering total. Slots typically count at one hundred percent, table games at ten percent or less, and some titles are excluded altogether. On a package demanding twelve thousand pounds of turnover, playing a game weighted at ten percent multiplies the effective requirement tenfold on that game. The practical consequence is uniform across the bracket: readers clearing a triple match end up on the slots, and the terms page names the excluded or reduced titles in a list that is worth reading in full before the first spin.
Maximum bet rules add a second layer. Most offers in this part of the market cap the size of a single stake while wagering is active, commonly at a few pounds, and breach the cap and the operator may void the winnings. A triple match encourages larger deposits and therefore larger instincts, and the max-bet clause is where those instincts most often cost people their balance. Check the figure, set a stake below it, and leave room for the rule to be enforced unevenly, because at the offshore end of the market there is no adjudicator to appeal to when it is.
Against the other multipliers
A three hundred percent match belongs to the aggressive end of the deposit-bonus spectrum. At the modest end, a hundred percent match on a hundred-pound deposit produces a hundred-pound bonus and, at forty times, four thousand pounds of turnover. A triple match on the same deposit triples the bonus and triples the turnover, and the cap usually fails to keep pace. The pattern that emerges across the bracket is consistent: as the headline percentage climbs, the multiplier holds or rises, the cap rises more slowly, and the expiry shortens. The offers get bigger and no better.
That is not a case against large matches, only against reading them at face value. A reader with a small bankroll who wants a long, cheap session is usually better served by a smaller match with clean terms. A reader who intends to chase a large bonus with a disciplined stake plan may find the triple match worth the volume. The model on this page exists so the choice is made with the real figures in front of you rather than the advertised ones.

Using the calculator
The calculator models the terms you enter against the deposit you plan. The prefill uses a hundred-pound deposit at a hundred percent match with a forty-times multiplier and a five-hundred-pound cap; to price the offer this page covers, raise the percentage box to three hundred and the turnover updates to the bonus-side figure. It rounds to whole pounds and assumes the terms printed by the operator at the time you read the page, so check the operator’s own terms before you deposit.
Modelled at the prefilled entries: a £100 deposit at a 100% match credits a £100 bonus, forty times wagering on bonus funds asks £4,000 of turnover, and the £500 conversion cap sits within reach of that volume. At 300% the same deposit credits £300 of bonus and the turnover at forty times rises to £12,000, so the cap to turnover ratio decides whether the larger offer is the better one.
Questions and answers
What does a 300% deposit bonus actually give me?
It credits three times your deposit in bonus funds alongside your cash, so a £100 deposit produces £300 of bonus and £400 of total playing balance. The bonus half carries wagering terms, a conversion cap and an expiry clock, so the withdrawable value depends on those terms rather than on the headline.
Why is the turnover on these offers so large?
The multiplier applies to the whole bonus, and a triple match triples the bonus. At forty times, a £300 bonus asks for £12,000 of staking before bonus winnings convert to cash, assuming slots contribute in full and the multiplier applies to bonus funds only.
Do I have to deposit the maximum to get the full percentage?
Not always, but many packages credit the full percentage only above a stated trigger, which can sit above the cashier’s minimum. The terms name the qualifying deposit. Below it you may receive a scaled-down match or, on some packages, no bonus at all.
Can I withdraw my deposit before finishing wagering?
On most offers of this sort, requesting a withdrawal while wagering is active forfeits the bonus and any winnings attached to it. Some operators let you cancel the bonus instead and keep the cash balance. The terms state which applies, and the difference is worth more than most headline figures.
What is a conversion cap and why does it matter here?
It is the ceiling on how much bonus winnings can be withdrawn. On large percentage matches the cap often sits below the bonus value, which turns the offer into a fixed-value voucher. Compare the cap to the turnover before comparing anything else.
Are table games a sensible way to clear a triple match?
Usually not. Table games contribute ten percent or less towards wagering on most offers, which multiplies the effective requirement tenfold on those games. The slots list in the terms is where the full-weighting games are named.
Is a 300% offer better than a 100% offer?
Better on size, rarely better on value. The larger match triples both the bonus and the turnover, and the cap usually rises more slowly than the headline. A smaller match with a generous cap and a low multiplier frequently returns more per pound deposited.
Do winnings from these bonuses get taxed?
No. Gambling winnings are not taxable for players in the United Kingdom, whatever the operator’s licence. Tax duties on remote gambling fall on operators, not on players.
An honest note on licensing
The kind of offer described on this page runs under offshore licences rather than a Gambling Commission licence, and the gap is practical rather than technical. GAMSTOP self-exclusion does not reach operators in this bracket, so registering with the national scheme will not close an account holding one of these packages. A UK-approved adjudicator cannot take a complaint, the regulator has no power to act, and UK fund protection rules do not apply. Safer-gambling tools such as time-outs and loss limits exist only where the operator volunteers them. Joining such a site is not unlawful for a British player, because the legal burden sits on the operator, but the recourse you would have at a licensed site does not exist here, and a deposit should be sized to money whose loss would not hurt.
