What it means
Many lotteries build their jackpots by rolling the prize forward whenever nobody wins. As the prize grows, more people buy tickets, which in turn makes the next jackpot grow faster.
The headline figure that appears on posters can reach levels that attract worldwide attention. The advertised amount is often not the cash that a winner would receive.
It is commonly the total of a series of annual payments, which reflects what the lottery would pay if it invested the prize pool and paid it out over many years. A winner can usually choose between the annuity and a smaller lump sum paid immediately.
The lump sum is smaller because of the time value of money, the idea that a dollar today is worth more than a dollar in the future. A fair lump sum is roughly the present value of the future payments, calculated at an assumed interest rate.
The higher the rate used, the smaller the lump sum compared with the headline. Tax also applies.
Prizes are generally treated as taxable income, and the amount withheld at payment may not equal the final bill, so winners often need advice on tax and on managing a large sum. Rules vary by country and by region, and they change, so check the current position where you live.
From a financial planning point of view, the more useful figure is the expected value of a ticket, which is the prize multiplied by the chance of winning, added up across all prizes. For almost every lottery this is less than the ticket price, so playing is entertainment and not an investment.
Anyone who does win benefits from taking professional advice before making major decisions.
In practice
Real-world examples.
Example
An office syndicate of eight people wins a lottery prize. Before collecting, they agree in writing how the winnings will be split and ask an accountant to explain the tax consequences. They choose the lump sum and place most of it in low-risk investments.
Example
A small casino advertises a progressive jackpot that grows with every bet placed on a linked machine. The finance team treats the growing prize as a liability and sets aside funds to cover it. The accounting follows the rules for gaming operators.
Example
A charity runs a raffle with a cash jackpot to raise funds. The treasurer checks the local rules on charitable gaming and records the ticket sales, the prize and the costs. The net proceeds go to the charity's projects.
Formula
Calculation
Present value = payment 1 / (1 + r) + payment 2 / (1 + r)^2 + payment 3 / (1 + r)^3
Suppose a jackpot is advertised as $3,641,000, paid in three annual instalments of $1,100,000, $1,210,000 and $1,331,000. Using a discount rate r of 10%, the present values are 1,100,000 / 1.10 = $1,000,000, 1,210,000 / 1.21 = $1,000,000 and 1,331,000 / 1.331 = $1,000,000. Total present value = 1,000,000 + 1,000,000 + 1,000,000 = $3,000,000. The lump sum would therefore be about $3,000,000, which is less than the $3,641,000 headline by 3,641,000 - 3,000,000 = $641,000.Case study
Seen in the real world.
Winfield Foods is an illustrative, fictional company whose employees pooled money each month to play a lottery. One month their ticket matched the top prize, and the group had to decide what to do with the winnings.
A finance manager among them explained the difference between the annuity and the lump sum. She calculated the present value of the payments at a reasonable rate and showed that the lump sum was close to what the annuity was worth. The group chose the lump sum and set aside money for tax.
They also agreed to share the proceeds equally and to use a financial adviser. Each member signed a short agreement confirming the split, which prevented disputes later. The illustrative lesson is that a large windfall creates planning needs, from tax to governance of a group, that are as important as the prize itself.
Watch out
Common mistakes.
- Treating the advertised jackpot as the cash a winner receives, when the annuity total is larger than the lump sum.
- Ignoring tax, when the amount withheld may differ from the final bill.
- Viewing lottery tickets as an investment, when the expected value of a ticket is almost always below its price.
