Settlement at the boosted price
A boosted price is a settlement instruction. When the selection wins, the capped part of the stake is multiplied by the boosted price and the rest by the market price; when it loses, both parts return nothing. This page works both outcomes through on the samples.

On settlement the stake inside the cap is multiplied by the boosted price and any stake above the cap by the ordinary market price. If the selection loses, both parts return nothing, so the uplift simply never pays in the majority of outcomes.
The two parts of one stake
The settlement arithmetic is two multiplications and an addition. It is worth writing out because the offer usually states only the first multiplication.
Worked example / sample I, a 100.00 stake, cap 10.00, 2.50 to 3.00
- the capped part: 10.00 x 3.00 = 30.00
- the uncapped part: 90.00 x 2.50 = 225.00
- returned if the selection wins: 30.00 + 225.00 = 255.00
- returned if the selection loses: 0.00
- the same stake with no boost, if it wins: 100.00 x 2.50 = 250.00
- what the uplift added: 5.00
How the sampled offers actually settled
| Outcome | Offers | Share | What it means |
|---|---|---|---|
| whole stake boosted | 342 | 74.0% | the stake was inside the cap, so one multiplication applied |
| part of stake at market | 120 | 26.0% | the stake exceeded the cap, so two applied |
| won | 209 | 45.2% | the uplift was paid |
| lost | 253 | 54.8% | the uplift paid nothing, as it must |
The rows do not sum to 462 because they answer different questions: the first two describe how the stake was priced, the last two whether anything was paid at all. Both pairs are worth reading beside each other, because a boost that is paid on 45.2% of outcomes and that prices only a quarter of the stake above the cap is a small, real, often-invisible addition.
Two settlement details worth knowing
- Where the cap is expressed as a maximum return rather than a maximum stake, convert it before comparing: a maximum return of 100.00 at a price of 3.00 is a cap of about 33.33 of stake.
- Where the boosted price applies to a slip, the settlement multiplies the whole combined price rather than each leg, so the cap binds on the whole stake and not per selection.
- Where the selection is void rather than lost, the settlement follows the market void rules first and the boost terms second - see when the price goes back.
