How To Use
1. Set Jackpot Rules
Enter the advertised jackpot and select your lottery game. The lump sum percentage and annuity duration auto-fill based on the game type. Powerball and Mega Millions typically offer 60% of the jackpot as the cash value option.
2. Apply Your Taxes
Enter your state tax rate. Use 0 for states with no income tax like Florida, Texas, Nevada, and Washington. The federal rate is always 37% for lottery winnings.
3. Predict 30-Year Returns
Enter your expected investment return rate if you plan to invest the lump sum. A conservative 7% annual return is used as the default based on historical balanced portfolio returns. Higher returns favor the lump sum option more strongly.

Frequently Asked Questions
Should I take the lottery lump sum or annuity?
For most financially disciplined winners, the lump sum wins decisively when invested wisely. Although the lump sum is only 60% of the advertised jackpot, the investment growth over 30 years at a conservative 7% annual return vastly exceeds the total annuity payments. A $500 million jackpot lump sum of $174 million net grows to over $1.3 billion in 30 years, compared to $290 million from the annuity. The annuity is safer for those who fear spending the lump sum immediately or lack investment knowledge.
What is the lump sum cash value of a lottery jackpot?
The lump sum (also called cash option or cash value) is typically 60% to 65% of the advertised jackpot for Powerball and Mega Millions. The advertised jackpot represents the total value of 30 annual annuity payments. The lottery authority has enough money on hand to pay the cash option immediately — the rest of the advertised amount represents future investment growth they expect to earn on the funds before making annuity payments.
How does the annuity actually work?
For Powerball and Mega Millions, the annuity consists of 30 payments made annually. The first payment is made immediately after claiming, and subsequent payments increase by 5% each year. This escalation is designed to help payments keep pace with inflation. Total annuity payments equal 100% of the advertised jackpot before taxes. Each payment is taxed as ordinary income in the year received at federal and state rates.
What happens to annuity payments if I die?
Annuity payments are typically transferable to your estate or heirs upon death. The remaining unpaid installments continue to be paid to your designated beneficiaries. However, the estate may face significant tax implications. Some states allow the estate to opt for a lump sum of remaining payments at that point. This is an important consideration for winners who are older — the lump sum eliminates uncertainty about future payment receipt.
At what investment return rate does the lump sum beat the annuity?
The crossover point depends on your tax rates and the annuity duration. At a 7% annual return, the invested lump sum typically surpasses the cumulative annuity value within 10 to 15 years and grows dramatically ahead thereafter. At very low investment returns of 2% to 3%, the annuity may actually be comparable or slightly better. The key insight is that historically the stock market has returned 7% to 10% annually, making the lump sum the superior financial choice for patient, disciplined investors.
