Welcome Bonus: The Match and the Turnover

What a welcome bonus is worth in money

A welcome bonus is a price quote with two lines on it. The first line is the match: 100% on a first deposit is the standard headline in this bracket, so £20 paid in produces a £40 balance, half of it cash and half of it bonus money. The second line is the turnover: at 40x on the bonus funds, that £20 of bonus money must be staked £800 worth before anything it wins turns into withdrawable cash. Read together, the deal costs £20 at the cashier and prices its reward at £800 of play, under a £500 ceiling that commonly sits over what the bonus side can convert.

Everything else on this page is commentary on those two lines. Bonus money is not money yet. It is a staking float with conditions attached: it normally cannot be withdrawn directly, it usually plays at full value only on games that count fully toward the meter, and it typically carries a maximum bet of £2 to £5 a spin while the turnover runs. The deposit itself generally stays cash, though terms differ on whether cash can leave early without forfeiting the bonus and everything it has won. Where the terms keep a separate bonus wallet, the boundary is visible in the balance; where they blend the two, the turnover clause is the only place the line is drawn.

The gap between the headline and the withdrawable is where the arithmetic lives. Take the worked figure again. A £20 deposit at a 100% match creates a £20 bonus, and turnover of 40x on that bonus asks for £800 of staked play. Played on slots, where weighting normally runs at 100%, the meter fills at the rate of the stake itself: 400 spins at £2, or 160 at £5. Put a 96% return on the machine, a common published figure for online slots, and the expected cost of churning £800 through the reels is about £32, because the house edge is the complement of the published return. That figure describes the long run the return is measured over, not any single session, and it is a costing rather than a prediction.

The £500 ceiling belongs in the same sentence as the match. If the bonus play converts at all, the common terms in this bracket stop the conversion at £500, so the most a worked run can return is the deposit plus whatever the bonus side banks under the cap, and the least is the deposit eaten down by the expected cost of the churn. A reader who wants none of it can usually decline the bonus at the cashier and play their own money without a meter at all, which is the quiet option the headline percent exists to distract from. Both outcomes deserve the same reading time; the point of the arithmetic is to know which outcome the terms have priced before the deposit leaves the account.

The match percent: the headline half of the deal

The match percent answers a simple question: for every pound deposited, how many pounds of bonus balance appear beside it. At 100%, a £20 deposit brings £20 of bonus. At 150%, the same deposit brings £30; at 200%, £40. The deposit-match structure is the standard welcome mechanic on the licensed British market, which is why the percent is the number every comparison starts from. Very high headline percentages, and tiered packages spread across a first, second and third deposit, are characteristic of the offshore-facing part of the market rather than the licensed one. The percent is the easiest number to compare and the reason offer shopping starts there; the rest of this page exists because it is not the number that decides the price.

The percent is also the least decisive number in the quote, because it says nothing about what the bonus costs to free. Two offers can print the same 100% and differ by a factor of two in price: one counts turnover on the bonus alone, the other on deposit and bonus together, which doubles the required play at a stroke. The percent also ignores the ceiling over conversions, the weighting table behind the meter and the clock on the whole exercise. A small match with fair terms is regularly the cheaper product, and the market leads with the percent because it is the line that reads well rather than the line that pays.

"Up to" does quiet work in the headline as well. A 100% match up to £500 pays the full doubling only to a reader who deposits £500; a £20 deposit at the same terms produces £20 of bonus, exactly as the small print of the arithmetic describes. Where a package spreads the match over several deposits, the later tiers usually arrive with their own turnover, their own window and sometimes their own cap, so the headline percent of the package is a sum of smaller deals rather than one number, and each tier needs costing on its own terms. The arithmetic is unforgiving about this: a percent without its ceiling is half a quote.

There is a floor to watch on the other side. Payment method minimums sometimes set the smallest deposit that triggers a bonus rather than the operator's own limit, and a deposit below the promotional minimum usually claims no match at all. The workable habit is to decide the deposit first, read the percent as the size of the float it creates, and only then turn to the turnover basis, the weighting, the cap and the clock, which between them set what the float will cost to free. That order runs against the way the offers are advertised, which is precisely why it tends to save money.

Turnover: the price tag behind the percent

Turnover is the number that turns a headline into a price. A wagering requirement multiplies the amount received by a stated figure, and the result is the play that must be staked before withdrawal: £10 of bonus at 40x requires £400 staked, and £20 at 40x requires £800. For the worked example this page takes 40x, because that is what this bracket of the market commonly asks. The multiple sits on the bonus funds alone in the cleaner version of the terms and on deposit plus bonus in the dearer one, and the difference between those two bases is a full doubling of the price.

"Staked" means every spin or hand plays its full value into the meter, win or lose. A £2 spin counts £2 toward the turnover whether it returns nothing or returns £80, which is why the meter fills at the speed of the stake rather than the speed of the luck. At a £2 maximum bet, the sort of ceiling British terms place on bonus play, clearing £800 takes 400 spins; at £5 it takes 160. The cap on the bet is therefore also a cap on how fast the condition can be met, and it is the reason a large match cannot simply be churned through in an evening.

Expected cost rides on the same arithmetic. The house edge of a slot is the complement of its published return, so a game returning 96% keeps about four pence of every pound staked over the long run the figure describes. Clearing £800 of turnover through such a game carries an expected cost of roughly £32, and a lower-returning game raises it in proportion. None of this predicts a session: the return describes the long run, and a short run lands where it lands. It is a costing, not a forecast, and it is the only honest way to weigh a 30x deal against a 45x one.

This is where turnover earns its keep as a sorting tool. Halve the multiple and the expected cost halves with it; double the basis and it doubles. A 100% match at 20x on the bonus is a cheaper product than a 200% match at 45x on deposit and bonus together, by a wide margin, even though the second headline is twice the size. When the turnover is met, the bonus converts to cash under whatever ceiling the terms print, and play that continues past the conversion rules does so on the terms' conditions, not the reader's. Weighting sits behind both halves of that comparison, which is why the next section takes it apart before the cap and the clock get their turn. The percent draws the eye; the multiple, the basis and the weighting decide whether the eye was worth drawing.

Weighting and bet caps: the rules of the meter

Game weighting decides which play actually feeds the meter. On typical British terms, slots count 100% toward wagering, while table games and live dealer games count far less or not at all. The consequence is mechanical: chase the turnover on roulette at a 10% weighting and every £100 staked buys £10 of progress, so the worked example's £800 of clearing stretches into £8,000 of actual play. That is why welcome terms steer play toward the slot hall, and why the weighting table is the second thing to read after the turnover basis. Weighting is also where a hurried reader loses the most time, because the meter looks as though it is moving while barely doing so.

The bet cap is the second rule on the meter. While a bonus is live, the maximum bet is typically £2 to £5 a spin, and staking above it can void the bonus and anything it has won. The cap paces the clearing as well: at £2 a spin, the worked example needs 400 spins, which is an evening or two at a steady rhythm rather than a minute of it. It also protects the shape of the offer itself, since a single large bet at full weighting would otherwise turn a turnover condition into a coin flip.

Licensed British slots carry stake limits of their own: £2 a spin for players aged 18 to 24 and £5 for players 25 and over, in force on the licensed market since 2020. Sites outside the licence hold no such cap, and the absence belongs to the licence-gap comparison rather than the sales copy, because the limit exists as a protection. Free spin bundles run on their own version of the same rules, with wagering commonly attached to the winnings the spins produce rather than to the spin value itself, and no-wagering batches, where winnings land as cash, remain the minority of the market.

The games most often tied to spin promotions in this market are Book of Dead and Big Bass Bonanza, which is useful context when a welcome package quotes a spin batch beside its match. What matters for the arithmetic is not the game's name but its weighting and its return. A spin batch whose winnings carry 40x wagering is a turnover condition in fancy dress; a no-wagering batch is cash in all but name. Read the weighting line and the wagering line together and most of the marketing falls away, leaving the price. The price is what spends, and everything else in the quote is description.

Caps: the ceiling over the withdrawable

A conversion cap is the ceiling over what bonus play can turn into cash. On typical British terms, caps sit around £100 or near the bonus value itself; across offers of this sort, £500 is the figure that recurs, and it is the figure the worked example carries. The cap does not touch the deposit, which remains cash throughout, but it bounds everything the bonus side produces: once conversion reaches the ceiling, further winning play on bonus terms stops converting, and the meter keeps turning only if the reader chooses to keep it turning. A cap is also the term most often skipped by readers in a hurry, and the one that most often changes the verdict.

The cap changes the shape of the upside rather than the size of the work. Turnover of £800 is owed whether the ceiling reads £100 or £500, so a tight cap means paying the full price for a bounded prize. That is the quiet argument for reading the cap before the percent: a large match under a small ceiling is a subscription to churn, while a modest match under a generous one at least leaves the play room to pay for itself. Terms sometimes express the ceiling as a multiple of the bonus rather than a pound figure, which is the same arithmetic in different clothes.

Ceilings tighten as deposits disappear. No-deposit offers, which credit a small balance or a spin batch before any payment, carry tighter caps and shorter windows than their deposit-match cousins, because the operator underwrites the whole float. Where a figure is published at all on those terms it tends to sit well under £100, and some terms print no explicit ceiling and rely on the conversion rules to do the limiting, which is harder to read and worth costing twice. A cap that never prints a number is not the absence of a cap; it is a cap defined elsewhere in the terms.

For the worked example, the cap closes the loop. A £20 deposit, a 100% match and £800 of turnover produce a bonus side that can convert at most £500, so the range of outcomes runs from the deposit minus the expected cost of the churn to the deposit plus £500. The expected cost, about £32 at a 96% return on slots, sits near the bottom of that range, and the ceiling sits at the top; where a run lands between them is the session's business, not the terms'. The terms' job is to state the range plainly, and the reader's is to price it before playing rather than after.

The clock: clearing inside 30 days

Time limits on bonus completion run from 7 to 30 days across the market, and 30 days is the typical window on offers of this sort, which is the figure the worked example uses. When the window closes, the bonus and usually everything it has converted are forfeited, so the clock is not decoration; it is the deadline that turns a comfortable price into a rushed one. The window starts at credit rather than at first play, which matters for anyone who claims a bonus and returns to it later in the week.

Pacing puts the window in human terms. The worked example needs £800 of staked play inside 30 days, which is about £27 a day, or 13 spins a day at a £2 stake: a comfortable pace. Thirteen spins a day is a minute at the reels; 133 would be a shift. Scale the deposit up and the maths hardens: a £200 bonus at the same 40x asks for £8,000 of play, 4,000 spins at £2, which is 133 spins a day, every day, for a month. The clock is one reason the same multiple reads differently at different deposit sizes, and one reason a bigger match is not automatically a better-priced one.

Free spin batches carry their own clocks, sometimes shorter than the match's window, and the wagering on their winnings runs on the same principle. A package spread across several deposits usually gives each tier its own deadline rather than one shared clock, so a second or third deposit starts its window later but finishes no more generously. Where a bonus sits unused while its window runs, the meter does not pause; the countdown is the one term that never negotiates, and expiry takes the conversions with it.

The practical order of reading is the window first, then the turnover it has to hold. A reader with a £20 budget and an evening or two a week matches the worked example's pace with room to spare. A reader planning one long session should check whether the bet cap and the window even allow the plan, because 400 spins at £2 is a few hours at the reels rather than a few minutes, and a term that expires mid-session takes its conversions with it. Thirty days is a fair clock for a small bonus and a tight one for a large deposit, and the deposit decision sets which side of that line the reader stands on.

The bracket, priced side by side

The comparison table gathers the two ends of the market onto one page: a licensed British baseline and an offshore-facing set of rows, with the cells that actually set the price of a welcome. Ranges are category-typical rather than quotes of any single promotion, and they move. The cells that matter most for a welcome are the wagering band, the minimum deposit and the licence beside them; in the comparison table the licence cell is the one to read first, because it decides which protections stand behind everything else in the row, and the checked date beside it dates the pass the rest of the row inherits.

Ranges, not quotes, is the discipline the table keeps. Two offers of the same kind can sit a full multiple apart on wagering and a ceiling apart on conversions, so a band is the honest description and any single figure would flatter one side of it. Where a cell reads as a band, the low end is the term to plan around, since a budget built on the friendly end of a band breaks on the unfriendly one. The licence date matters for the same reason: terms drift, and a row is only as current as its check.

Read as a bracket, the licensed rows carry smaller headline matches, wagering that starts lower, £10 floors and PayPal in the cashier, with winnings back to debit cards in one to three banking days as the norm. The offshore rows carry the bigger percents, wagering in the 35 to 45 band, £20 floors and crypto rails where the licensed cashier has none, and none of the licensed baseline terms are claimable at those offers. The licence gap behind that split has its own section on this page; the price of it lives in the turnover and cap cells, which is where a welcome bonus is truly costed.

Cost a welcome bonus before claiming it

This calculator runs the worked example's arithmetic on any figures entered into it. The prefilled case is the one costed throughout the page: a £20 deposit, a 100% match, 40x turnover on the bonus funds and a £500 ceiling on what the bonus side can convert. Three further assumptions sit behind the numbers: all play goes through slots at 100% weighting, the maximum bet while wagering is held to £2 a spin, and the 30-day window typical of this bracket is the clearing allowance. Change any input and the price changes with it; the turnover basis, bonus only versus deposit plus bonus, moves the total more than any other line.

The output to carry away is the required turnover, because it is the one number a cashier never prints next to the percent. Against it, the expected cost of the churn reads at roughly 4% of turnover for a 96% return slot, and the pacing checks by dividing turnover by the days available and again by the capped stake. A result that needs more spins than the window can sensibly hold at the capped bet is a deal priced beyond the time it asks for, whatever the headline says. The same inputs answered at a £5 capped bet instead of £2 halve the spin count and double the pace, which is why the bet cap belongs in the model rather than in the footnotes.

The model is deliberately plain. It does not know the weighting table of a particular game, the volatility of a session or the shape of a run of luck, and it is not a prediction of what a bonus will return; it prices the conditions and nothing else. Used that way it does the one job worth doing before a claim, which is to turn a percent into a price and let the reader decide whether the price is worth paying.

What a UK licence adds to the same arithmetic

A UK licence would not change the match percent, but it would change everything the percent sits on. A Gambling Commission licence requires operators to offer account-level protections: deposit limits that take effect immediately, time-outs and reality checks on session length, with a 24-hour cooling-off option for any player who asks for a break. Those tools sit inside the same account the bonus is claimed from, which is what makes them usable in the moment rather than theoretical.

The licence also buys a complaints route and a net. A licensed operator must participate in alternative dispute resolution, so a disagreement over a converted bonus has somewhere independent to go, and GamStop covers licensed sites, so a self-exclusion applies across every GB-licensed operator at once for a chosen period of six months, a year or five years. Registration is free, and participation returns automatically when the chosen period lapses. None of that machinery reaches a site outside the licence, because the scheme is built on the permission the site does not hold.

Stake and payment rules ride on the licence too. Online slots on licensed British sites have been capped at £2 a spin for players aged 18 to 24 and £5 for players 25 and over since 2020, credit card deposits have been banned since April 2020, and PayPal appears on licensed British cashiers because the method requires the local licence before it can be offered in a market. Those are the visible edges of the protection package, and their absence elsewhere is part of the honest comparison rather than a detail of taste.

Two constants hold on both sides of the licence line. Winnings from gambling are not taxable for players in the United Kingdom, and the odds are the odds: a random number generator governs slot outcomes, and the published return describes the long run rather than any session. What differs is everything around the game: the limits, the cooling-off, the dispute route and the self-exclusion net. Licence claims made by offshore operators are theirs; this site has not verified them against a register and never repeats a licence number, and the public register is searchable by anyone who wants to check an operator before depositing.

That is the framing worth carrying back to the welcome offer: the percent prices the bonus, the licence prices the protections behind it, and a reader who values the protections can find them on the licensed rows of the comparison table and pay the smaller headline for them. The smaller headline is not a worse offer once the protections are priced in; it is the same offer with the guardrails included.
