How many Powerball combinations are possible?
Number selection
5 main numbers from 1 to 69 + 1 Powerball from 1 to 26.
Combination formula
C(69,5) × 26
Total full combinations
292,201,338
Powerball uses 5 main numbers from 1 to 69 and 1 Powerball from 1 to 26. The Powerball is selected separately, giving 292,201,338 possible full top-prize combinations.
Powerball top-prize chance by unique lines
The table assumes every line is different in the same draw. Repeating a line does not cover another possible combination.
| Lines covered | Estimated ticket cost | Approximate chance | Equivalent odds |
|---|---|---|---|
| 1 unique line | £4.00 | 0.000000342% | 1 in 292,201,338 |
| 7 unique lines | £28.00 | 0.000002396% | 1 in 41,743,048 |
| 14 unique lines | £56.00 | 0.000004791% | 1 in 20,871,524 |
| 21 unique lines | £84.00 | 0.000007187% | 1 in 13,914,349 |
How the calculation works
For one unique line, the chance is:
1 ÷ 292,201,338 × 100
For several unique lines, the chance is:
number of unique lines ÷ 292,201,338 × 100
Example: with 7 unique Powerball lines, the top-prize chance is 7 ÷ 292,201,338 × 100 = approximately 0.000002396%.
Calculate your chance by number of unique lines
Enter any number of unique 5-number + Powerball lines from 1 to 292,201,338 to calculate the approximate top-prize chance and estimated ticket cost.
This calculator assumes every line is unique. Repeated lines do not cover another possible combination. It shows the chance of matching all 5 main numbers plus the Powerball only, not the chance of winning any smaller prize. Cost is an estimate using £4 per Powerball line; official channels and prices always prevail.
When do UK Powerball sales close?
You need to play by 11:55pm on Monday, Wednesday and Saturday for the draw taking place early the next morning. Lottery-Checker resets the shared Powerball board at that UK sales cutoff.
Why unique Powerball lines matter
If several Powerball players use favourite numbers, repeats can happen. Checking the shared board first helps the group cover different full combinations.
Lottery-Checker cannot improve the official odds of any individual line. The practical benefit is organisation: if a line is already marked as used here, another player can choose a different line and cover a different combination instead of repeating the same one.
Check Powerball results and plan new lines
The Powerball results checker compares lines saved on this browser, or 1-7 lines you type for a one-off check, with the latest published draw. After checking the result, use the shared board to plan new 5-number + Powerball combinations and avoid lines already marked here.

Frequently asked questions
Are these the chances of winning any prize?
No. They show the chance of matching the full top-prize combination only. Smaller prize tiers have different odds.
Does avoiding duplicate lines improve my odds?
It does not improve the odds of one individual line. It can help a group avoid repeating the same planned combination and cover more unique combinations.
Does marking a line buy a ticket?
No. Marking a line on Lottery-Checker is only a planning action. It does not buy a ticket or enter anyone into a draw.
When is the Powerball sales cutoff in the UK?
UK sales close at 11:55pm on Monday, Wednesday and Saturday for the draw taking place early the following morning.
