How It Works
Formula
Annual payment = jackpot / annuity years
Average monthly payout = annual payment / 12
Total payout = annual payment x annuity yearsThe equal-payment annuity model divides the full advertised jackpot by the number of years in the payout term. That produces one level annual payment before tax. The monthly figure is just that annual amount divided by 12, and the total payout stays equal to the advertised jackpot before tax.

Worked Examples
A 30-year 1 million dollar jackpot
Divide $1,000,000 by 30 to get $33,333.33 a year. Divide that by 12 to get an average monthly payout of $2,777.78.
A 25-year 5 million dollar jackpot
A $5,000,000 annuity spread evenly over 25 years pays $200,000 each year before tax. The monthly average is $16,666.67.
Common mistakes
- Comparing this pre-tax annuity result to an after-tax lump-sum offer
- Assuming the monthly figure is the actual payment schedule instead of a budgeting average
- Treating the advertised jackpot as cash in hand instead of the full annuity value
Limitations
This tool uses a simple equal-payment annuity model. Real lottery annuities can follow game-specific schedules, including payments that rise each year instead of staying flat. It does not account for federal or state tax, inflation, discount rates, present value, or what you might earn by investing a lump-sum option.
