For every dollar we spend getting a TOTO ticket, we are risking it by subjecting ourselves to the probability of winning something.

How much do I need to spend to at least win something?

To calculate the probability of winning at least some money, we sum up all the above-mentioned probability to derive at 0.0186. Which works out to be about 1 in 53.76.

This means that one needs to at least fork out $53.76, about 54 TOTO tickets to at least win some money.

Editor’s note: You can use this fraction calculator here.

Sounds good? Think again.

  • For Group 5, Group 6 and Group 7, the payout is $50, $25 and $10 respectively.
  • Hence, winning any of the group will result in you losing money given that the cost price is at $53.76.
  • Only by winning at least a Group 4 will the “investment” makes economic sense.

How much to win at least a Group 4 then?

  • Assuming we use the same data of the Hong Bao Draw in the year 2017, there are 2,516 Group 4 winners bagging $346 each.
  • We now turn a blind eye to anything Group 5 and below, we calculate to see how much we need to put in to win a Group 4 at least.
  • The odds of winning a Group 4 at least turns out to be 1 in 3,932.51.
  • This means that we need to put in at least $3,932.51 for a chance to win at least $346, which again, is not worth it.

The ultimate chart you need to illustrate the never-ending pursuit of quick wealth (based on 2017’s result):

GroupHow much you need to buy?How much you win?
(based on 2017's Draw)
$13,983,816$3,000,413 - $10,983,403
2$1,997,688$89,083 or more- $1,908,605 or less
3$53,991.25$1,514 or more-$52,477.24 or less
4$3,932.51$346 or more- $3,586.51 or less
5$849.12$50 or more- $799.12 or less
6$415.07$25 or more- $290.07 or less
7$53.76$10 or more- $43.76 or less

The above chart shows that in order for a sure win, one needs to put in so much more money to compensate the risks and the odds.

  • In order for one to win at least a Group 2, he needs to put in close to $2 million. The returns? A possible change of winning $89,083 or maybe, $3 million.
