How to use this tool

1
Enter the game format

How many numbers a ticket picks, and how many numbers are in the pool — 6 from 49 is the classic example.

2
Add a bonus ball if there is one

In Advanced, enter how many bonus balls must also match; the jackpot odds multiply accordingly.

3
Read jackpot and match odds

Jackpot odds sit at the top, with match-3, match-4 and match-5 odds beneath.

4
Check the expected value

Enter the jackpot and ticket price to see what a ticket is worth on average — almost always less than its price.

Formula & worked example

Combinations C(n, k) = n! ÷ (k! × (n − k)!). Jackpot probability = 1 ÷ C(pool, picks), multiplied by the bonus-ball factor when one applies. Matching exactly k numbers is hypergeometric: C(picks, k) × C(pool − picks, picks − k) ÷ C(pool, picks). Expected value = jackpot × jackpot probability − ticket price.

6 from 49: C(49, 6) = 13,983,816 combinations, so the jackpot is 1 in 13,983,816. Matching exactly 3 numbers is 246,820 ÷ 13,983,816, about 1 in 56.66. A $10 million jackpot makes a $2 ticket worth about $0.72 on jackpot value alone.

Limitations — read this before you rely on it

Expected value here covers the jackpot only, not smaller prizes, taxes, or the chance of splitting a jackpot with other winners — all of which lower what you actually take home. Odds assume one random draw with no repeated numbers on a ticket.

Frequently asked questions

For 6 numbers from 49 it is 1 in 13,983,816. Every game format is different — enter your game's picks and pool to get its exact odds.

No. Every combination is equally likely in a fair draw, and past draws do not influence future ones.

Jackpot × jackpot probability, minus the ticket price. It is almost always negative, which is how lotteries fund their prizes.

With the hypergeometric formula: ways to match 3 of your numbers times ways to miss the other 3, divided by all combinations — about 1 in 56.66 for 6 from 49.

Yes — the jackpot must then also match the bonus draw, so the jackpot combinations multiply by the number of bonus balls.
