Formula and how it works
Example with real numbers
Here is the Powerball Calculator using the default values shown in the calculator above:
Inputs
| Advertised jackpot ($) | 400,000,000 |
|---|---|
| Tickets bought | 10 |
| Cash value (%) | 48 |
| Federal tax (%) | 37 |
Results
| Odds of winning | 29,220,134 |
|---|---|
| Cash value | $192,000,000.00 |
| After federal tax | $120,960,000.00 |
With these inputs the calculator returns Odds of winning: 29,220,134. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Advertised jackpot ($) from 400,000,000 to 480,000,000 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Odds of winning | 29,220,134 | 29,220,134 | 0% |
| Cash value | $192,000,000.00 | $230,400,000.00 | +20% |
| After federal tax | $120,960,000.00 | $145,152,000.00 | +20% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
