Lottery Lump-Sum Buyout Calculator

Won a lottery annuity (Powerball, Mega Millions, or a state game) and considering selling it for a lump sum? See the present value, the typical buyer offer, federal + state tax, and whether the lump sum actually beats taking the annuity.

Estimate only. IRS mandatory federal withholding on lottery payouts is 24% — your final tax depends on your marginal bracket. This calc uses your marginal bracket directly. Consult a CPA before signing — trust structures, charitable offsets, and tax-rate elections materially change the math.

When this makes sense — and when it doesn't

When it makes sense

  • You have a documented high-ROI use — paying off high-interest debt (15%+ APR), an established business with proven margins, or a primary residence.
  • You're in a no-state-tax state where the lump-tax-hit is bearable.
  • The discount rate the buyer offers is below your break-even rate.
  • You expect federal tax rates to rise — locking in current bracket has real value.

When it doesn't

  • You don't have a clear, ROI-positive use for the cash — most lump-sum lottery winners are broke in 5–10 years.
  • You're in a high-tax state — the lump-tax-hit can wipe out the discount-rate advantage.
  • The buyer's discount rate is north of 15% — that's a steep premium for liquidity.
  • Your annuity grows (some do, 4–5%/yr) — growth dramatically tilts the math toward holding.

How the break-even works. The "break-even discount rate" is the rate at which the after-tax lump sum exactly equals the after-tax annuity total. If the buyer's offered rate is above break-even, you're getting a worse deal than just holding. If it's below break-even, the lump beats the annuity in nominal dollars — though that ignores investment opportunity, which is the real argument for taking it.
