Introduction
A $500,000 structured settlement over 20 years is not worth $500,000 today. The present value at a 4% discount rate is approximately $340,000 -- meaning a claimant who accepts structured payments in lieu of a lump sum is effectively receiving 32% less in real purchasing power. Yet structured settlements provide tax-free income, guaranteed payments regardless of market performance, and protection against spending a lump sum too quickly. The National Structured Settlements Trade Association reports that structured settlements fund over $6 billion in annual payments to injured claimants in the US. Understanding the lump-sum equivalent value versus the structured stream is the core financial decision in any settlement negotiation. This calculator runs both sides of that math -- what is the settlement worth today, and what does each option pay after attorney fees, costs, and taxes.
What This Calculator Does
This settlement payout calculator computes net-to-plaintiff for both lump-sum and structured settlement options. For lump sums, it deducts attorney fees, case costs, and medical liens to produce the net cash amount. For structured settlements, it calculates the present value of the payment stream at a user-specified discount rate and shows the after-fee net of the present value. It also projects the future value of a lump sum invested conservatively for comparison.
The Formula
For a lump sum, the net is straightforward: gross settlement minus all deductions. For a structured settlement, the present value discounts each future payment back to today's dollars using the discount rate r, where n is the number of periods until that payment. The discount rate typically reflects a conservative investment return (3% to 5%) or the annuity rate used by the structured settlement company. Net structured value applies attorney fees to the present value equivalent, not the total future payment stream.
Step-by-Step Example
Enter the lump sum offer details
Gross lump sum offer: $320,000. Attorney fee at 33.33%: $106,667. Case costs: $14,500. Medical liens (negotiated): $28,000. Net lump sum: $320,000 - $106,667 - $14,500 - $28,000 = $170,833.
Enter the structured settlement terms
Structured offer: $2,500/month for 20 years = $600,000 total. Discount rate: 4%. Present value of payment stream: $412,800. Attorney fee on PV: $137,600. Net structured PV after fee, costs, liens: $412,800 - $137,600 - $14,500 - $28,000 = $232,700.
Compare the options
Net lump sum: $170,833 available immediately. Net structured PV: $232,700 equivalent over 20 years. The structured settlement provides $61,867 more in present value terms, but the claimant must wait up to 20 years to realize it and cannot access the capital if needs change.
Model the lump sum investment alternative
If the $170,833 net lump sum is invested at a 5% annual return, it grows to $453,400 over 20 years -- significantly more than the structured settlement total of $600,000 in nominal terms but comparable in present value terms. The choice depends on the claimant's financial discipline and investment access.
Real-World Use Cases
Plaintiff Attorney Client Counseling
Before presenting a settlement offer to a client, the attorney runs both lump-sum and structured scenarios showing net-to-client in present value terms. A client who initially rejects a $275,000 lump sum as too low may reconsider when the structured alternative's present value net is shown to be only $14,000 higher after 20 years of payments.
Mass Tort Allocation Planning
In a mass tort settlement with tiered payouts, each plaintiff's net payout at their specific injury tier, attorney fee percentage, and medical lien amount needs individual calculation. Running the calculator for each tier level shows the distribution of net-to-client amounts across the plaintiff class.
Medicare Set-Aside Planning
For settlements involving Medicare beneficiaries, a Medicare Set-Aside (MSA) allocation must be included in the settlement structure when future medical care for the injury is reasonably anticipated. The calculator models how an MSA amount reduces the net payout and whether the remaining recovery still meets the client's minimum acceptable threshold.
Comparison
| Factor | Lump Sum | Structured Settlement | Consideration |
|---|---|---|---|
| Tax treatment | May be taxable (depends on case type) | Generally tax-free under IRC 104(a)(2) | Structured has tax advantage for large amounts |
| Immediate access | Full amount immediately | Periodic payments only | Lump sum advantage if capital needed |
| Spending risk | High -- no guardrails | Low -- forced savings | Structured protects impulsive spenders |
| Investment upside | Yes -- claimant keeps gains | No -- locked rate | Lump sum advantage in high-return environments |
| Creditor protection | State-dependent | Strong in most states | Structured provides stronger protection |
| Flexibility | Full -- no restrictions | Very limited after signing | Lump sum advantage for life changes |
Common Mistakes to Avoid
Comparing lump sum and structured settlement on gross amounts rather than present values. A $600,000 structured settlement over 20 years is not worth $600,000 today. Comparing it to a $350,000 lump sum on face value misleads the client.
Forgetting that attorney fees on structured settlements are often calculated on the present value, not the total future payments. An attorney taking 40% of a 20-year $600,000 structured settlement should take 40% of the present value (approximately $165,000), not $240,000. Some fee agreements are unclear on this point.
Not accounting for Medicare Set-Aside requirements. Settlements above $25,000 where Medicare is a secondary payer may require a formal MSA evaluation and CMS submission. Ignoring this can expose the claimant to Medicare benefit suspension for future injury-related treatment.
Assuming the structured settlement annuity rate is equivalent to a guaranteed investment return. Structured settlement annuity rates (typically 3% to 4.5% in 2026) reflect insurance company pricing, not market returns. In high-rate environments, a lump sum may outperform the annuity if invested conservatively.
Frequently Asked Questions
Accuracy and Disclaimer
Settlement calculations are estimates based on user-provided terms and assumptions. Tax treatment of settlements depends on case type, applicable law, and individual circumstances. Present value calculations use discount rates that may not reflect actual investment returns. Medicare Set-Aside requirements depend on CMS thresholds and individual claimant Medicare status.

Consult a licensed attorney, tax advisor, and settlement consultant for case-specific guidance.
Conclusion
Settlement math is rarely as straightforward as the gross number on the check. Use our Contingency Fee Calculator to model the attorney fee component precisely before running payout scenarios, and consider pairing this with our Case Value Estimator if you are still in the negotiation phase and need to evaluate whether the current offer reflects the likely case value range.
