Compare a lump-sum buyout with a structured payment stream by looking at present value, COLA growth, payment timing, and purchasing power.
Introduction to structured settlement annuity and lump-sum analysis
A structured settlement decision becomes easier to evaluate when you translate the payment schedule into present value and compare it with the buyout on the table. This Structured Settlement Annuity Comparison Calculator takes the lump sum, periodic payment, payment frequency, growth assumption, discount rate, and inflation assumption, then places them in the same comparison frame.
That matters because structured settlements are often discussed in narrative terms: how the checks arrive, whether the stream rises over time, and how much flexibility the cash offer provides. The financial tradeoff, however, lives in the timing. A dollar paid years from now is not automatically equivalent to a dollar available today. This calculator makes that timing visible without deciding what personal tradeoff is right for you.
Use the explanation below to match the entries to the settlement contract, understand the present-value calculation, and test the assumptions most likely to move the result. The calculator is a comparison tool, not legal, tax, investment, or financial advice.
What this structured settlement annuity comparison helps you decide
For this structured settlement calculator, the central question is whether the scheduled payment stream is worth more or less than the immediate lump sum after discounting. An annuity can look generous when you add every future check together, yet compare differently once those future dollars are brought back to today’s value. The reverse can also be true when a long stream has a meaningful annual increase.
A practical decision usually includes more than the larger calculated number. You may value immediate liquidity, predictable income, protection against spending a large cash amount quickly, estate planning, or a specific need such as housing or debt repayment. The output does not choose among those priorities. It shows which option the math favors under the discount rate and inflation assumptions you select, so that the non-math considerations can be considered openly.
How to use the structured settlement annuity comparison calculator
Start by reading the settlement documents rather than estimating from memory. Enter the cash amount available today as the lump-sum offer. Then enter the amount of one scheduled payment, select whether that payment occurs monthly or annually, and enter the number of years the stream continues. If the contract raises payments over time, enter its stated annual increase or COLA. Finally, choose the annual discount rate you want to use and, if useful, an inflation assumption for a purchasing-power view.
- Enter the actual Lump sum offer ($) available today.
- Enter the first scheduled Payment amount ($), not the annual total unless the schedule is annual.
- Select the contract’s Payment frequency and enter the promised Number of years.
- Add any fixed Annual increase / COLA (%), then choose your annual Discount rate.
- Optionally enter inflation, click Compare, and keep the entered assumptions with the result.
When testing a revised quote, change one input at a time. That makes it clear whether a new result is driven by the offered cash, a payment increase, the term, or the rate used to value future money.
Structured settlement offer inputs and contract details to verify
The fields in this structured settlement annuity comparison calculator describe the cash offer, payment schedule, and economic assumptions used to turn future checks into today’s dollars. Most errors come from mixing monthly and annual values or from overlooking a scheduled increase. Check the contract’s payment calendar and any rider before relying on an output.
- Lump sum offer ($): the cash amount offered today in exchange for the future payment stream.
- Payment amount ($): one payment at the start of the schedule, before growth is applied.
- Payment frequency: monthly means twelve payment dates per year; annual means one payment date per year.
- Number of years: the length of the stream represented by the entered recurring payment.
- Annual increase / COLA (%): a fixed annual growth assumption. Enter zero if payments are level.
- Discount rate (annual %): the annual rate used to value later payments less heavily than earlier payments.
- Inflation assumption (annual %, optional): the annual loss of purchasing power used for the real-value calculation.
Use the same time basis throughout. For example, do not enter a monthly payment amount while treating it as an annual payment, and do not enter an annualized payment in the monthly setting. If the actual contract has irregular installments, a deferred start date, a life-contingent payment, a guaranteed period, fees, or index-linked increases, this level-payment model may not represent every term.
Formulas for discounting structured settlement payments
For this structured settlement comparison, each future payment is grown by the annual increase you enter, converted to the selected payment frequency, and then discounted back to today. The lump sum is already a present-day amount, so it serves as the cash benchmark against the structured stream.
Here, P is the first periodic payment, N is the number of payment periods, g is the per-period payment growth rate, and d is the per-period discount rate. The calculator converts the annual growth and discount percentages into per-period rates using the selected frequency. In other words, a monthly schedule is valued payment by payment rather than as one annual amount.
The nominal total adds all scheduled future payments without discounting them. The present value discounts the stream for timing. The inflation-adjusted present value first expresses each future payment in today’s purchasing power and then discounts it. That real-value figure is useful for understanding whether apparently growing checks keep pace with price changes under the inflation rate you entered.
Worked example: comparing a 20-year structured settlement quote
Suppose a settlement purchaser offers $500,000 today, while the existing settlement pays $40,000 annually for 20 years with no COLA. Enter $500,000 as the lump sum, $40,000 as the payment, select annual frequency, enter 20 years, set the annual increase to 0%, and use a 5% discount rate. The nominal payment total is $800,000, but that total does not mean the stream is worth $800,000 today because many payments arrive far in the future.
At a 5% discount rate, the calculator discounts the first $40,000 payment for one year, the second payment for two years, and so on through the twentieth payment. The resulting present value can then be compared directly with the $500,000 cash offer. Raising the discount rate makes distant payments count less; adding a genuine COLA makes later payments larger before they are discounted. If the same $40,000 figure were monthly instead, selecting monthly is essential because it represents a very different payment stream.
This example is a sanity check, not a recommendation to accept or reject an offer. Review whether payments are guaranteed, whether there are future lump installments, and whether the buyer’s quote includes deductions or fees before treating any simplified comparison as complete.
How structured settlement assumptions move the comparison
The direction of a result usually follows a few understandable patterns. A lower lump-sum offer generally makes the structured stream look stronger. A higher discount rate generally lowers the present value of the structured payments, especially when the schedule lasts many years. A larger COLA tends to improve the stream’s value, while higher inflation reduces its purchasing power.
| Scenario |
What changes |

What to verify |
| Lower lump-sum offer |
The cash buyout falls while the schedule is unchanged. |
The structured annuity usually looks stronger on present value. |
Confirm the buyer is purchasing the same payments and applying the same terms. |
| Higher discount rate |
Future payments are discounted more aggressively. |
The present value of the structured stream usually falls relative to cash. |
Use a rate that reflects your own opportunity cost and risk view. |
| Higher COLA |
Later scheduled payments grow more quickly. |
The structured side usually gains value. |
Verify whether the increase is fixed, capped, or linked to an index. |
| Higher inflation |
Future dollars have less purchasing power. |
The real present value of the stream falls. |
Distinguish the inflation assumption from the discount rate. |
These are directional checks rather than guaranteed outcomes. The exact answer depends on the complete schedule, term, and rates you enter. Use the table to identify why an output changed, then return to the settlement documents to verify the relevant term.
How to interpret the structured settlement comparison result
The results panel compares the structured stream’s present value with the lump sum. If the structured PV is higher, the payment stream is mathematically stronger under your selected discount rate. If the lump sum is higher, the immediate cash offer is stronger on present value alone. A result that is close may mean that liquidity, spending discipline, creditor protection, benefits, family needs, and other personal circumstances deserve as much attention as the dollar difference.
The nominal total is useful for understanding the promised total checks, but it is not a today-value comparison. The inflation-adjusted PV helps show how much purchasing power the future stream may represent after inflation. A large gap between nominal and real PV is a reminder that future dollars can buy less even if the payment amount never changes.
A positive displayed difference means the structured payment stream is higher by that amount; a negative difference means the lump sum is higher. Save the frequency, term, COLA, discount rate, and inflation assumptions with any result so the comparison can be reproduced if the offer or your assumptions change.
Limitations and assumptions in structured settlement annuity comparisons
No structured settlement annuity comparison calculator can capture every detail of a real offer. This tool assumes regular end-of-period payments, a steady discount rate, a steady inflation rate, and a fixed growth rate when one is entered. It does not model taxes, legal approval requirements, assignment restrictions, insurer credit risk, fees, changing interest rates, public-benefit effects, survivor rights, or a schedule with irregular lump payments.
Read settlement paperwork literally. A life-contingent annuity, a guaranteed-certain period, a cost-of-living adjustment tied to an index, or a partial sale can require a more detailed cash-flow analysis. For a consequential decision, discuss the contract and any sale proposal with a qualified attorney, tax professional, fiduciary adviser, or other professional appropriate to your circumstances. The calculator’s value is making the assumptions explicit so you can ask informed questions.
