Should you take the lump sum or the annuity payments? Compare a one-time payout against monthly or yearly payments and find your break-even return rate.
A lottery winner can take $500,000 today or $2,000 per month for 25 years (300 payments). Assuming a 6% annual return:
Lump Sum Future Value: $500,000 ร (1.06)ยฒโต = $2,145,935
Annuity Future Value: 300 monthly payments reinvested at 6% = $1,385,688
Total Cash Received from Annuity: $2,000 ร 300 = $600,000
Winner: Lump sum โ ahead by ~$760,247
Break-even Rate: only ~1.6%. If the winner can earn more than about 1.6% per year, the lump sum is the better choice.
The lump sum wins because the entire $500,000 compounds for the full 25 years, while annuity payments are invested gradually over time.
A settlement offers $100,000 today or $650 per month for 20 years (240 payments). Assuming a 4% annual return:
Total Cash Received from Annuity: $650 ร 240 = $156,000 (56% more than the lump sum)
Lump Sum Future Value: $100,000 ร (1.04)ยฒโฐ = $219,112
Annuity Future Value: 240 payments reinvested at 4% = $238,427
Winner: Annuity โ ahead by ~$19,315
Break-even Rate: about 5.1%. If the recipient can consistently earn more than 5.1% per year, the lump sum becomes the better choice.
At modest return rates, spreading payments out can actually beat investing a lump sum โ even though the annuity pays out only $156,000 in total cash.
A retiree is offered a $300,000 pension buyout or $1,500 per month for life (modeled here as 25 years). Assuming a 7% annual return:
Lump Sum Future Value: $300,000 ร (1.07)ยฒโต = $1,628,230
Annuity Future Value: 300 payments reinvested at 7% = $1,215,571
Total Cash Received from Annuity: $1,500 ร 300 = $450,000
Winner: Lump sum โ ahead by ~$412,659
Break-even Rate: about 3.8%. At the assumed 7% return, taking the buyout and investing it clearly wins.
With a pension, life expectancy matters: if you live much longer than 25 years, the monthly payments keep coming โ adjust the years in the calculator to model your own situation.
This calculator compares two ways of receiving the same windfall โ a lottery jackpot, insurance payout, structured settlement, or pension buyout. It projects how much each option would be worth at the end of the term if all money is invested at your expected annual return rate.
The break-even return rate is the annual return rate at which the lump sum and the annuity grow to exactly the same future value. It is found by solving:
Winners of large prizes, insurance payouts, structured settlements, and pension buyouts face the same choice: take a lump sum today, or receive a stream of annuity payments. Each option has a very different financial profile, and the "right" answer depends on your expected investment return, spending discipline, life expectancy, and tax situation.
This calculator compares both options fairly: the lump sum is invested at your expected annual return, and each annuity payment is also reinvested at the same rate. The option with the higher future value wins.
Many assume the lump sum is always better because "a dollar today is worth more than a dollar tomorrow." That is only true if you invest it and earn a decent return. If you would spend it quickly, or cannot beat the break-even rate, the annuity can be the smarter choice.
The single most useful number in this decision. If you expect to beat it, take the lump sum; if not, take the annuity.
A lump sum can be spent quickly; annuity payments impose a natural budget. If you doubt your ability to keep the lump sum invested, the annuity may be worth more in practice.
Both options are projected to a future value at the end of the term using the same annual return rate, so the comparison is apples to apples.
At a 0% return rate, the annuity future value is simply the sum of all payments and the lump sum stays flat. If years is 0, both options are worth $0. If the payment is 0, the annuity is worthless and the lump sum is the only choice.
The break-even rate is the annual return where both future values are equal, solved by bisection between 0% and 30% (tolerance 0.01%). If the lump sum wins even at 0%, break-even is 0%; if the annuity still wins at 30%, it is above 30%.
For example, a $500,000 lump sum versus $2,000 per month for 25 years breaks even at only about 1.6% โ most long-term investors beat that, making the lump sum the better choice. A $100,000 settlement versus $650 per month for 20 years breaks even at about 5.1%, a much harder target.
Beyond the pure math, several real-world factors should shape your decision. The calculator gives you a clear financial answer at your assumed return rate, but the final choice is personal.
A lump sum is typically taxed in the year you receive it, which can push you into a higher tax bracket. Annuity payments spread the tax over many years.
An annuity provides guaranteed income and removes investment risk. A lump sum gives you control but exposes you to market downturns.
