About this calculator
The present value of a structured settlement is the lump sum that is worth the same, today, as the stream of future monthly payments. This calculator assumes the payments rise each year with your expected inflation rate (as cost-of-living-adjusted settlements do), so it discounts them at the real rate — the discount rate minus inflation. The formula is: PV = monthlyPayment × [1 − (1 + r)^(−n)] / r, where r = (discountRate − inflationRate) / 100 / 12 is the monthly real rate and n = paymentYears × 12 is the number of payments (when r = 0 the PV is simply monthlyPayment × n). The discount rate represents the return you could earn on invested money of similar risk. A higher net discount rate makes future payments worth less today. Compare the result with the lump sum offer: if the PV of the payments is higher than the offer, the payment stream is worth more, all else equal. If your payments are fixed and do not rise with inflation, enter 0 for inflation so they are discounted at the full nominal rate.
How to use
Assume monthly payments of $2,000 for 20 years, a 6% discount rate, 2% inflation, and a lump sum offer of $300,000. Step 1 — Net (real) rate r = (6 − 2) / 100 = 0.04 a year, or 0.003333 a month. Step 2 — Number of payments n = 20 × 12 = 240. Step 3 — Annuity factor = [1 − (1.003333)^(−240)] / 0.003333 ≈ 165.02. Step 4 — PV = $2,000 × 165.02 ≈ $330,044. The payment stream is worth about $30,000 more than the $300,000 lump sum offer, so on these assumptions the structured payments are the better deal. If the payments were fixed (enter 0% inflation), the PV at 6% would be about $279,161, and the lump sum would win.
Frequently asked questions
How does the inflation rate affect the present value of a structured settlement?
Inflation erodes the purchasing power of future payments, so it is subtracted from the nominal discount rate to produce a real (inflation-adjusted) net rate. This calculator assumes the payments rise with inflation, so a higher inflation rate lowers the net discount rate and increases the present value. If your payments are fixed in dollars, inflation erodes them instead — enter 0 for inflation to value fixed payments at the nominal discount rate. Conversely, very low inflation combined with a high discount rate produces a lower PV, making the lump sum relatively more attractive. Using a realistic, long-run inflation estimate — often 2–3% — is critical for an accurate comparison.
When should I accept a lump sum instead of structured insurance settlement payments?
A lump sum is typically preferable when the offered amount exceeds the calculated present value of future payments, meaning the insurer is effectively paying you more than the stream is worth. It also makes sense if you have high-return investment opportunities, immediate large expenses like medical bills or debt payoff, or concerns about the insurer's long-term solvency. On the other hand, structured payments provide income certainty and protection against spending the money too quickly, which may be valuable for individuals without strong financial discipline.
What discount rate should I use for evaluating an insurance settlement present value?
The discount rate should reflect the return you could reasonably earn by investing a lump sum over the same period at comparable risk. Common benchmarks include long-term Treasury bond yields (currently around 4–5%), high-grade corporate bond yields, or a conservative blended portfolio return. Avoid using aggressive stock market return assumptions (e.g., 10%) because that introduces equity risk the structured settlement does not carry. Many financial and legal experts recommend using a rate between 4% and 6% for structured settlement analysis to reflect low-to-moderate risk alternatives.
