Attorney Fee Split Calculator

Introduction: What This Calculator Estimates

This attorney fee split calculator estimates how a legal settlement may be distributed when a lawyer is paid by contingency fee. It separates the gross settlement into an attorney fee, reimbursed case costs, liens or other deductions, and the client's estimated net amount. That makes it easier to read a proposed settlement statement, compare fee agreement language, and test how much each cost item changes the final disbursement.

The most important detail is the fee base. Some contingency agreements apply the attorney's percentage to the full gross recovery before expenses are reimbursed. Others reimburse approved case costs first and then apply the fee percentage to the remaining amount. Those two methods can produce different client shares, especially when expert fees, filing costs, deposition transcripts, travel, medical records, or trial-preparation expenses are large. The calculator supports both methods so you can match the written agreement instead of relying on a one-size-fits-all shortcut.

How to Use the Calculator

Start with the gross settlement or judgment amount before attorney fees, costs, liens, taxes, or other deductions. Enter the contingency fee percentage from the fee agreement, such as 33.33 percent, 35 percent, or 40 percent. Then enter case costs that must be reimbursed from the recovery. These are usually litigation expenses advanced by the lawyer or paid from the client's portion, not the attorney's percentage itself.

Use the liens and other deductions field for amounts that reduce the client's disbursement after the attorney fee and case costs are accounted for. Common examples include medical liens, workers' compensation reimbursement claims, health insurer subrogation, child support liens, litigation funding repayment, or negotiated provider balances. If you are only comparing attorney fee structures and do not know lien amounts yet, leave this field at zero and treat the result as a pre-lien estimate.

Finally, choose the fee base shown in the fee agreement. Use gross settlement when the attorney's percentage is applied before reimbursing costs. Use settlement after costs when costs are subtracted first and the percentage applies to the reduced amount. The result panel reports the fee base, attorney fee, case costs, other deductions, client net, and the percentage of the gross settlement that remains for the client.

Formula and Method

Let S be the gross settlement, p the contingency percentage as a decimal, K the reimbursed case costs, and L the liens or other deductions entered by the user. When the fee is based on the gross settlement, the calculator uses:

Attorney fee = S x p

Client net = S - attorney fee - K - L

When the fee is based on the amount remaining after reimbursed costs, the calculator uses:

Fee base = max(S - K, 0)

Attorney fee = fee base x p

Client net = S - K - attorney fee - L

The max function prevents a negative fee base when case costs exceed the settlement. The client net can still be negative, which signals that the entered costs and deductions are larger than the recovery. That does not mean the client automatically owes the difference; fee agreements, lien reductions, litigation funding contracts, local rules, and attorney discretion may change the real-world outcome. It is a warning to review the settlement statement carefully.

Worked Example

Suppose a case settles for $100,000, the contingency fee is 33.33 percent, reimbursed case costs are $6,000, and medical liens are $12,000. If the fee applies to the gross settlement, the attorney fee is about $33,330. The estimated client net is $100,000 - $33,330 - $6,000 - $12,000, or $48,670. The client keeps about 48.7 percent of the gross settlement before taxes or personal obligations not entered in the calculator.

If the same agreement applies the fee only after reimbursing costs, the fee base is $94,000. The attorney fee becomes about $31,330, and the estimated client net rises to $50,670. The difference is about $2,000 because the contingency percentage was not applied to the reimbursed cost amount. This is why the fee-base wording matters and why a settlement statement should show the order of deductions, not just the final check amount.

Interpreting the Result

A higher client net is not automatically proof that one fee agreement is better. A higher contingency rate may accompany a more difficult case, a longer litigation timeline, a greater risk of no recovery, or a lawyer advancing substantial expenses. A lower rate may still produce a lower client check if costs, liens, or funding repayments are large. The calculator is most useful when you run several scenarios: early settlement versus trial, 33.33 percent versus 40 percent, gross-fee base versus net-of-costs fee base, or lien reduction versus no lien reduction.

Pay attention to the client share percentage. It translates the final client amount into a share of the gross settlement, making it easier to compare cases of different sizes. If the client share looks unexpectedly low, review whether costs were double-counted, whether liens have been negotiated, whether litigation funding fees are included, and whether the attorney fee percentage changes at different stages of the case.

Assumptions and Limitations

This calculator does not create an attorney-client relationship and does not provide legal, tax, or financial advice. It assumes the entered settlement is already known and does not evaluate liability, damages, settlement probability, comparative fault, statutory fee caps, court approval requirements, minors' compromise rules, probate approvals, or class-action distribution rules. It also does not decide whether a fee is reasonable under professional conduct rules.

The calculator treats liens and other deductions as user-entered amounts. In practice, medical providers, insurers, government benefit programs, litigation funders, and other lienholders may negotiate or assert different balances. Tax treatment also varies. Many physical-injury recoveries are treated differently from punitive damages, interest, wage claims, emotional-distress claims without physical injury, or fee-shifting employment cases.
