What is the prize allocation method?

The number of prizes entered into each Monthly Free Prize Draw will vary from month to month. This will depend on the value of the Windfall Bond's Monthly Prize Fund, and how many prizes can therefore be allocated based on that amount.

Windfall Bond Prize Fund Value

The value of the Windfall Bond's Monthly Prize Fund will vary each month, in proportion with the value of Windfall Bonds entered into the previous month's free Prize Draw.

The Prize Fund Value will be calculated by taking the total value of Windfall Bond deposits entered into the previous month’s free Prize Draw, multiplied by 1%, and divided by 12.

As an example, the prize fund for February would be calculated as the total value of Windfall Bond deposits entered into January's prize draw, multiplied by 1% and divided by 12.

More information on how to calculate the Prize Fund value can be found in clause 9 in the Prize Draw Rules, which is also contained within the Product Features leaflet.

Prizes

The number of prizes are allocated into five levels:

Level A prize: £50,000
Level B prize : £10,000
Level C prize: £1,000
Level D prize: £500
Level E prize: £100

Prizes are allocated across the five levels A to E based on the following:

1. First, we calculate 60% of the total monthly prize fund value and divide this value into as many whole Level A prizes as possible. Where this value does not divide exactly into whole number multiples of the Level A prize value, the number of Level A prizes is rounded down to the nearest whole number.
2. Once the number of Level A prizes has been determined, the remaining unallocated monthly prize fund is then split into as many whole Level B prizes as possible. We calculate 50% of the remaining unallocated monthly prize fund and divide this value into Level B prizes. Where this value does not divide exactly into whole number multiples of the Level B prize value, the number of Level B prizes is rounded down to the nearest whole number.
3. Once the number of Level B prizes has been determined, the remaining unallocated monthly prize fund is then split into as many whole Level C prizes as possible. We calculate 50% of the remaining unallocated monthly prize fund and divide this value into Level C prizes. Where this value does not divide exactly into whole number multiples of the Level C prize value, the number of Level C prizes is rounded down to the nearest whole number.
4. Once the number of Level C prizes has been determined, the remaining unallocated monthly prize fund is then split into as many whole Level D prizes as possible. We calculate 50% of the remaining unallocated monthly prize fund and divide this value into Level D prizes. Where this value does not divide exactly into whole number multiples of the Level D prize value, the number of Level D prizes is rounded down to the nearest whole number.
5. Once the number of Level D prizes has been determined, any remaining unallocated monthly prize fund is then split into Level E prizes.

At the end of this process the total monthly prize fund will be allocated in full amongst the five prize levels.

As an illustrative example, based on 12,000 qualifying entries, the number of prizes would be allocated as follows:

This equates to 108 prizes from a total Prize Fund worth £100,000.
