How to use Lottery Annuity vs Cash Calculator
Defaults: advertised jackpot $400,000,000, cash option 51 percent, annuity years 30, tax 24 percent. Those four knobs are how US multi-state lotteries actually sell a jackpot: a giant nominal sum paid over decades, or a smaller lump that is the present value of that schedule. Enter the billboard number in Advertised Jackpot. Enter the published cash-option percentage (often printed as a dollar cash value; convert cash/advertised × 100 if you only have dollars). Annuity Years is 30 for Powerball and Mega Millions. Tax is a single blended withholding-style rate for illustration — not your true marginal rate.
Calculate. Cash Before Tax = advertised × cashPct = $400,000,000 × 0.51 = $204,000,000. Cash After Tax applies (1 − tax): $204,000,000 × 0.76 = $155,040,000. That highlighted cash-after-tax figure is the number most winners actually bank. Avg Annuity / Year is the naive advertised/years = $400,000,000 / 30 ≈ $13,333,333, which is not how MUSL actually pays (see the math block). Annuity / Year After Tax multiplies that average by 0.76 ≈ $10,133,333.
If your lottery publishes cash as a dollar amount instead of a percent, divide cash by advertised and put that percent in. A $400 million ad with $192 million cash is 48 percent, not 51. If you live in a state that taxes lottery winnings, raise Tax; if you live in a no-state-tax jurisdiction, you may still owe federal withholding and a year-end true-up. 24 percent is the US federal backup withholding rate on gambling, not the 37 percent top ordinary rate.
Compare the two paths with the same tax rate so you do not mix a pre-tax annuity headline with an after-tax lump. The calculator does not discount the annuity at a Treasury yield; it only splits the face. If 30 equal payments of $13.33 million were really on offer, their present value at 5 percent would be about $13.33m × 15.372 ≈ $205 million, which is why a 51 percent cash option is in the right ballpark for a flat schedule. Real Powerball payments escalate about 5 percent a year for 30 payments; the first cheque is much smaller than $13.33 million.
Most winners take cash. Use this page to see why: they prefer a known lump, they do not want 30 years of counterparty and political risk, and they can invest the lump themselves. The annuity can still win if you want a forced savings plan, you distrust your future self, or you would spend a lump destructively. Plug your real advertised and cash-option figures, not the defaults, before you call a lawyer.
About this calculator
US lotto jackpots are advertised as the undiscounted sum of a 30-payment annuity. That is legal marketing, not fraud, and it is the reason a “$400 million jackpot” is not $400 million in the bank. The Multi-State Lottery Association (Powerball) and the Mega Millions consortium both offer a cash option equal to the prize fund’s actual cash sitting in Treasuries and similar instruments — typically a bit under or around half the advertised face when long rates are in a mid-single-digit range. European operators more often pay a cash jackpot and skip the annuity theatre entirely.
History: 1980s and 1990s US lotteries leaned on annuity packaging because a $10 million cash prize invested in Treasuries funded a larger nominal stream, and because a 20- or 26-year payout reduced the chance a winner would immediately blow the principal. Powerball settled on 30 graduated payments. Winners were later given a cash election; empirically, the vast majority elect cash. Estate, divorce, and “friend who also wants a cut” complications are easier with a lump that can be structured through a trust than with a state-issued payment stream that may or may not be assignable.
The 24 percent default tax is US federal gambling withholding, not a tax advice figure. Large prizes are ordinary income. The winner’s true federal rate can reach the top bracket, plus state tax in many jurisdictions, plus the 3.8 percent Net Investment Income Tax does not apply to lottery prizes the way it applies to portfolio income — but state treatment varies. The UK National Lottery pays prizes tax-free to the winner (the operator has already remitted lottery duty). Canada taxes lottery prizes as windfalls not included in income. Do not export the 24 percent US default to those regimes.
This calculator is a first cut, not a financial plan. It ignores: the real MUSL 5 percent escalating schedule versus a flat 1/30 split; the option value of investing the cash lump in a portfolio that might beat or trail the implicit annuity rate; early-death risk (annuity usually pays an estate the remaining guaranteed payments, but read the booklet); assignment and factoring markets that buy annuity streams at a further discount; and charitable remainder structures. SorteCalc will not file your return.
Use it when a headline number is being used to sell tickets or to brag. Convert to cash, haircut tax, then decide. If the cash-after-tax number still changes your life, the annuity-versus-cash decision is about control and time preference, not about combinatorics. Pair with the tax calculator for a two-rate federal-plus-state split, and with the prize-split calculator if you shared the ticket.
Math under the hood
United States multi-state jackpots are advertised as the undiscounted sum of a thirty-payment annuity. That marketing identity is legal and it is the reason a four-hundred-million billboard is not four hundred million in the bank. The Multi-State Lottery Association and the Mega Millions consortium offer a cash option equal to the market value of the funded stream, typically near half the advertised face when long rates sit in the mid single digits. European operators more often pay cash and skip the theatre.
The default knobs are advertised jackpot 400,000,000 dollars, cash option 51 percent, 30 years, tax 24 percent. Cash before tax is advertised times the cash fraction: 400,000,000 times 0.51 equals 204,000,000. Cash after tax applies the flat haircut (1 minus 0.24): 204,000,000 times 0.76 equals 155,040,000. That after-tax lump is the figure most winners actually bank. Average annuity per year is the naive advertised divided by years, 400,000,000 / 30, about 13,333,333. After tax that average is multiplied by 0.76, about 10,133,333.
Notice what this page does not do. There is no net-present-value discounting of the annuity at a Treasury yield. The worksheet only splits the face and applies a flat tax. If thirty equal payments of 13.33 million were really on offer, their present value at 5 percent would be about 13.33 million times 15.372, near 205 million, which is why a 51 percent cash option is in the right ballpark for a flat schedule. Real Powerball instalments escalate about 5 percent a year; the first cheque is much smaller than one-thirtieth of the billboard. The printed yearly average therefore overstates early income and understates late income.
Tax is a single blended rate for illustration, not a true marginal schedule. Twenty-four percent is United States federal backup withholding on gambling, not the top ordinary rate of 37 percent and not a state tax. Spreading thirty instalments across thirty tax years can change the effective average if brackets are progressive; taking cash can spike one year. This arithmetic applies the same tau to both paths so you do not mix a pre-tax annuity headline with an after-tax lump.
Present-value intuition still belongs in the lecture even though the tool omits it. If your personal discount rate is 8 percent, the annuity’s present value sits below the cash cheque and cash dominates further. If your discount rate is 1 percent, the graduated stream can look attractive, still subject to political and longevity footnotes in the official rules. Most winners take cash because the cash option is already the present value of the promised stream, before tax timing.
Assumptions: advertised face is the undiscounted sum; cash percent is the published option, not a yield you invented; tax is flat; no estate overlay, no assignment market, no charitable remainder. Plug the real advertised and cash-option numbers from the claim form, not the teaching defaults, before you call a lawyer. Order of operations for a shared jackpot is convert to cash, split among tickets, then tax each share.
