How raffle odds are calculated
TL;DR summary
Raffle odds = Your Tickets / Total Tickets for a single winner. With 5 tickets out of 500 total, you have a 1% (1 in 100) chance of winning. For multiple winners, the calculation becomes more complex but generally your odds improve. Unlike lotteries, raffle odds are fixed and known - you can calculate exactly how many tickets to buy for your desired probability.

Common raffle questions
For a single winner: divide your tickets by total tickets. With 10 tickets out of 1,000 total, you have 10/1,000 = 1% or 1 in 100 chance. For multiple winners, the math is more complex but your odds of winning at least one prize generally improve.
It depends on your budget and desired odds. For a 5% chance with 1,000 tickets sold, you need 50 tickets. Calculate: Desired Probability × Total Tickets = Tickets Needed. Consider the prize value vs ticket cost for expected value.
