Winning the Mega Millions jackpot is a dream shared by millions. But when you hit the lucky numbers, you’re faced with a big decision: Do you take the full jackpot over 30 years (annuity), or do you go for the one-time cash option? The lump sum payout sounds appealing, but it comes with significant tax implications. To make the best decision, you need accurate calculations — and that’s where the Mega Millions Cash Option Calculator comes in.

What Is the Cash Option in Mega Millions?
When someone wins the Mega Millions jackpot, they have two payout options:
- Annuity: The full advertised jackpot paid in 30 increasing yearly installments.
- Cash Option (Lump Sum): A one-time payment that represents the current cash value of the jackpot.
The cash option is significantly lower than the advertised amount. For example, if the jackpot is $500 million, the lump sum might be around $290 million — and that’s before taxes.
Why Is the Cash Option Less Than the Jackpot?
The advertised jackpot assumes the total value paid out through annuity over 30 years, backed by U.S. government securities. The cash option reflects the current value of the prize if you were to receive it all at once.
This is called the present value — the amount of money that, if invested today, would grow (at interest) to equal the advertised jackpot over time.

Formula Used in the Mega Millions Cash Option Calculator
This calculator uses a simple structure to estimate your final payout, based on publicly available Mega Millions financial models.
Plain Text Formula:
- Cash Value Estimate:
Cash Option = Jackpot × Present Value Factor
(Present Value Factor is typically ~0.55 to 0.61) - Federal Taxes:
Federal Tax = Cash Option × Federal Tax Rate
(Federal rate is usually 24% to 37%) - State Taxes (if applicable):
State Tax = Cash Option × State Tax Rate - After-Tax Payout:
Lump Sum After Tax = Cash Option – Federal Tax – State Tax
Example Calculation
Let’s say you’ve won a $500 million jackpot.
- Cash Option Estimate:
$500M × 0.61 = $305 million - Federal Tax Deduction (24%):
$305M × 0.24 = $73.2 million - State Tax (e.g., 6%):
$305M × 0.06 = $18.3 million - Final Lump Sum:
$305M – $73.2M – $18.3M = $213.5 million
So while the advertised jackpot is $500 million, your actual take-home payout could be around $213 million if you choose the lump sum and live in a state with a 6% tax rate.

Some prefer the annuity for stability, while others want full control immediately — this calculator helps make that choice clear.
