Pay What You Pull Raffle Revenue

Select Pay what you pull for a complete set of tickets numbered 1 through N, where each ticket costs its number multiplied by a dollar step. Enter N and the dollars per number, then optionally enter prize costs and other expenses. The result shows revenue if every numbered ticket sells once, average ticket price and net proceeds after those costs.

Gross revenue = step × N × (N + 1) ÷ 2. Average ticket price = step × (N + 1) ÷ 2. Net proceeds = gross revenue − prize costs − other expenses. These are sellout totals, not a sales forecast. If tickets remain unsold, add the actual prices paid for the tickets sold; multiplying the sellout total by the fraction sold can give the wrong actual revenue.

For example, 100 tickets numbered 1 through 100 at $1 per number bring in $5,050 if all sell once. The average ticket price is $50.50. With $750 in prize costs and $50 in other expenses, net proceeds are $4,250. A different starting number, repeated numbers or discounts changes the sum.

Raffle Ticket Winning Chance Formula

The following formula is used to calculate the chance of winning when exactly one winning ticket is drawn (a single-prize / single-winner raffle).

Chance of Winning (%) = ((Tickets Purchased) / (Total Tickets)) × 100

Variables:

  • Total Tickets is the total number of tickets in the drawing (typically the total number of tickets sold/issued).
  • Tickets Purchased is the number of tickets you have bought (the number you own).

To calculate your chance of winning a single-prize raffle, divide the number of tickets you own by the total number of tickets in the drawing and then multiply by 100 to get a percentage. If multiple prizes are drawn, the chance of winning at least one prize depends on how many winning tickets are drawn and whether winning tickets are removed; select Chance of at least one prize in the calculator above, then enter the prize draws and ticket-handling rule.

What is a Raffle?

A raffle is a type of contest where people purchase numbered tickets, and one or more winning ticket numbers are drawn at random. The holder(s) of the winning ticket(s) receive the prize(s).

How to Calculate Your Chance of Winning a Raffle?

The following steps outline how to calculate your chance of winning in a raffle.

  1. First, determine the total number of tickets in the drawing (typically the number sold/issued).
  2. Next, determine the number of tickets you own.
  3. If there is exactly one winning ticket (one prize), use the formula: (Tickets Purchased / Total Tickets) * 100.
  4. If there are multiple prizes/winners, select Chance of at least one prize in the calculator above, then enter the prize draws and ticket-handling rule (the probability is not simply Tickets Purchased / Total Tickets).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Total Tickets Available = 500

Tickets Purchased = 5. For exactly one prize, the chance is 5 / 500 × 100 = 1%.
