Prize Draw Odds Calculator
Work out your real chance of winning a UK prize competition before you buy. Enter the maximum number of tickets, the ticket price and how many you want, and the calculator shows your odds if the draw sells out, what you'll spend and how much prize value you get for every £1.
Enter the total tickets, ticket price and how many you'll buy to see your odds. Tickets you buy can't be more than the total tickets.
How the calculator works
Every UK prize draw has a maximum number of tickets. Your odds if the draw sells out are the total tickets divided by the number you hold. If a draw has 5,000 tickets and you buy 5, your odds are 1 in 1,000.
If fewer tickets sell, your odds improve, because the draw goes ahead with fewer entries. That is why the calculator shows a best case based on tickets sold so far. Most draws keep selling until they close, so treat the sold-out figure as your guaranteed worst case.
Comparing two competitions
Odds alone don't tell you which draw is better value. A £10 ticket with 1 in 500 odds and a £1 ticket with 1 in 5,000 odds give you the same chance per pound. The prize value per £1 figure shows which draw gives you more prize for your money if both sell out.
