Mega Million Annuity Calculator
What Is the Mega Millions Annuity Option?
Mega Millions offers winners two options for receiving their jackpot prize:
- Lump Sum (Cash Option) – One-time payment of the jackpot’s current cash value before taxes.
- Annuity Option – Paid out over 30 annual installments, with each installment increasing by approximately 5% annually.
The annuity option is the advertised jackpot amount, but few realize that this total includes investment returns over time. So, understanding how much you actually receive each year—and how taxes reduce your payout—is crucial.

Mega Millions Annuity Calculation Formula (Plain Text)
Here are the formulas behind the calculator:
1. Lump Sum Cash Value:
Cash Value = Jackpot Amount × Lump Sum Factor
(Typical Lump Sum Factor = ~0.60 for Mega Millions)
2. Federal Tax Deduction:
Federal Tax = Cash Value × Federal Tax Rate
(Federal Rate: 24% withholding by default; could be higher depending on total income)
3. State Tax Deduction:
State Tax = Cash Value × State Tax Rate
(Varies from 0% to 10% depending on the state)
4. Annual Annuity Payments:
The total annuity amount is divided into 30 increasing payments.
Year n Payment = Base Payment × (1.05)^(n-1)
(Each year increases by 5%)
To find the base payment (Year 1):
Let P = Total Jackpot
Let r = 5% (increase rate)
Let n = 30 years
Then:
Base Payment = P × (1 – r) / (1 – (1 + r)^–n)
After tax, each year is adjusted using:
Net Payment Year n = Payment × (1 – Federal Tax Rate – State Tax Rate)
Example Calculation
Let’s walk through an example:
Jackpot Amount: $100,000,000
Lump Sum Factor: 0.60
Federal Tax Rate: 24%
State Tax Rate: 6%
Lump Sum Option:
- Cash Value: $100,000,000 × 0.60 = $60,000,000
- Federal Tax: $60,000,000 × 0.24 = $14,400,000
- State Tax: $60,000,000 × 0.06 = $3,600,000
- Net Lump Sum: $60,000,000 – $14,400,000 – $3,600,000 = $42,000,000
Annuity Option:
- Total Jackpot (before tax): $100,000,000
- Year 1 Payment (base): approx. $1.5M
- Year 30 Payment: approx. $6M
- Total Pre-tax Payments: $100M over 30 years
- Total Taxes per year: varies but typically reduces each installment by 25–35%
- Net Annual Payments: range from ~$1.1M (Year 1) to ~$4.5M (Year 30)
