100 percent deposit bonus: the straight match, fully costed

The baseline shape of an even match

A 100% deposit bonus is the ratio the rest of the welcome market measures itself against: money in, the same amount credited, pound for pound. Nothing in the ratio is clever, and that is the point. The 200%, 300% and 400% shapes that share this corner of the market take the same skeleton and multiply the credit, and each of them pays for the bigger number somewhere in the terms. The even match is where those trade-offs start from, which is why it deserves costing on its own terms rather than being waved through as the modest cousin.

The ratio also hides where the money actually sits. In most terms the deposit keeps its own character and the matched half is held as bonus funds, released as wagering clears or paid out at the end of it. A 100% deposit bonus therefore reads, at the moment of deposit, as half locked money, and the whole question of value moves off the percentage and onto the wagering multiple, the game weighting, the expiry window and the cashout cap. Two offers with identical headlines can sit far apart once those four dials are read.

The baseline also sets the comparison a reader should carry across the welcome family. Spins packages attach a fixed value to a fixed number of rounds, no deposit offers carry no stake from the player at all, and the even match asks for a real deposit and returns a real credit. Between the three, the even match is the honest middle: the player’s money stays visible in the deal, and so does the operator’s condition for releasing its share of it.

Where the typical band sits

Ask what a 100% deposit bonus usually looks like and the band is tighter than the marketing suggests. The minimum deposit that unlocks the match sits at £10 to £20 at most cashiers, with £5 appearing where a brand courts small stakes and £20 at the premium end. The match cap usually falls between £50 and £200, which means a £50 deposit normally buys the full even match and a larger deposit buys the cap, not a larger percentage of anything.

Wagering is the wide dial. Licensed cashiers commonly ask 20 to 35 times or 30 to 45 times the bonus; offers at this end of the market, offshore, more often ask 35 to 50 times. On a £50 bonus the gap is not academic: a 30 times requirement is £1,500 of turnover, 45 times is £2,250, and 50 times is £2,500, so the same credit can carry a thousand pounds of difference depending on where in the band the terms land.

The rest of the band runs through expiry windows, commonly seven to thirty days, through stake limits while the bonus is live, and through the cashout cap, which this page treats as the decisive figure. Where an offer sits on all four dials, not where its percentage sits, is what a deposit is actually buying. Assumptions are stated wherever the arithmetic needs one, because a model that hides its multiplier is worth less than none.

The model in four bars

The chart behind this section plots the model in four bars, and the shape of the bars is the argument of the page. The first two are equal: a £50 deposit and the £50 credited against it, the even match doing exactly what its name promises. The third bar is the expected cost of clearing the turnover, £70 at the assumptions set out in the next section, and it stands taller than either of the first two. The fourth is the cashout cap, £200, the tallest bar on the chart because it is a ceiling rather than an expectation.

Nothing in the model says the bonus reaches its cap. The cap only marks where the operator’s obligation stops, and the gap between the turnover bill and the cap is where the offer’s real value lives. Read the bars in that order and the 100% deposit bonus stops being a ratio and becomes a price: the credit is the first bar, the clearing cost is the third, and the space between them decides whether the deal was worth the deposit that opened it. A heavier match would redraw the same chart with taller credit and, in practice, a taller turnover bar; the cap rarely moves in proportion.
