Before you hire an attorney, you probably want to know what the legal help could cost and what you may actually receive if your claim succeeds.
That’s what this calculator helps you work out. Add what the injury has cost you so far and a few details about your case to see an estimated settlement range, what may go toward attorney fees and case costs, and what could ultimately reach you.
Calculate My Attorney Fees
How to Use This Calculator
The calculator takes you through two short steps to build your estimate.
Step 1: Enter Your Damages
Start with your financial losses from the injury, and select the severity that best matches your condition:
- Total medical bills: Enter what you have spent on emergency care, hospital stays, surgery, therapy, medication, and other treatment. Include expected future treatment if you have an estimate.
- Lost wages and income: Add the income you missed because your injury kept you from working. You can leave this at zero if you did not lose income.
- Property and vehicle damage: Enter the cost of repairing or replacing damaged property, such as your vehicle. Skip this field if your claim does not involve property damage.
- Injury severity: Choose minor, moderate, or severe based on the description that best matches your injuries. Your selection helps determine the pain and suffering multiplier used in the estimate.
You can use approximate amounts if you do not have final bills or exact totals yet.
Step 2: Add Your Case Details
Next, answer a few questions that affect how the estimated recovery and attorney fee are calculated:
- Where you expect the case to resolve: Choose whether you expect the claim to settle before a lawsuit, after a lawsuit is filed, or after going to trial. The calculator applies the corresponding contingency percentage shown with each option.
- Who was at fault: Select whether the other party was fully responsible or you shared some fault. If you select shared fault, the calculator adjusts the estimate to account for your portion of responsibility.
- How case costs are deducted: Choose whether costs are taken out before or after the attorney fee is calculated. This can change both the estimated attorney fee and the amount remaining for you.
Once you complete both steps, you’ll see your estimated economic damages, pain and suffering range, gross settlement, attorney fee, and potential take-home amount.
Note: This calculator is designed for personal injury claims handled on a contingency fee. Other types of legal matters may use a different fee structure.
How Attorney Fees Work in Oklahoma
How you pay depends largely on the type of legal matter, the work involved, and the fee arrangement you agree to with your lawyer.
The Oklahoma Bar Association identifies hourly fees, flat fees, and contingency fees among the common ways attorneys can charge for their services. A lawyer may also require an advance payment or retainer, depending on the arrangement.
Here’s a brief breakdown:
| Fee Structure | What It Means for You | Common For |
|---|---|---|
| Hourly rate | You pay for each hour the attorney works, billed against an upfront retainer. | Family law, business disputes, contested litigation |
| Flat fee | You pay one agreed price for a defined service, so you know the total before you start. | Expungements, uncontested divorces, wills, simple immigration filings |
| Contingency fee | You pay nothing up front, and the attorney is paid an agreed percentage only if you recover money. | Personal injury cases |
| Retainer | You deposit funds up front, and the attorney draws from them as work is completed. | Ongoing criminal defense and hourly matters |
For contingency cases, Oklahoma requires the fee agreement to be in writing and signed by the client. It must explain how the fee is calculated, including applicable percentages, what litigation expenses will be deducted, and whether those expenses come out before or after the contingency fee is calculated.
According to the Oklahoma Bar Association, the contingent fees commonly range from 25% to 50% of the recovery, although the actual percentage depends on the agreement between the client and attorney.
What Affects the Cost of a Lawyer
Two people can hire attorneys for similar legal matters and end up with very different costs. Your legal services cost can depend on how much work the case requires and how the attorney charges for that work.
Factors that may affect your attorney fees include:
- Type of case: Attorney fees can vary depending on the type of legal matter and the amount of work it typically requires.
- Complexity: More complicated cases may cost more because they can require additional research, investigation, document review, or preparation.
- Time involved: Legal matters that require more attorney time can lead to higher fees, particularly when the attorney charges by the hour.
- How far the case progresses: Fees may increase when a case continues into litigation or trial because more legal work is required as the case moves forward.
- Attorney experience: Hourly rates and other fees can vary based on an attorney’s experience and the legal services involved.
- Case expenses: Your overall legal costs may be higher when the case requires expenses such as filing fees, expert witnesses, investigators, medical reports, or service fees.
The Oklahoma Bar Association recommends discussing both fees and costs before hiring an attorney so you understand what you will be responsible for paying.
Compare Costs by Practice Area
The type of case often determines both how an attorney charges and how much the legal work may cost.
The figures below are industry averages:
| Practice Area | Typical Fee Structure | Estimated Cost Range |
|---|---|---|
| Criminal defense | Flat fee or retainer | $1,500 to $10,000+, depending on the charge and case complexity |
| Family law (divorce, custody) | Hourly with retainer, flat fee if uncontested | $1,500 for uncontested matters to $10,000+ for contested cases |
| Immigration | Flat fee per filing | $1,000 to $8,000+ by visa or green card type |
| Personal injury | Contingency, no upfront cost | Typically 33% to 40% of the recovery |
| Probate and trust administration | Hourly or percentage of the estate | $2,500 to $8,000+ depending on the estate size |
| Estate planning | Flat fee | $300 to $3,000+, depending on the documents and planning required |
These figures can help with initial planning, but you need a fee agreement to tell you what a particular attorney will charge and what services that amount covers.
How to Interpret Your Estimate
Use the estimate to understand how the details of your case, attorney fees, and case costs factor into the amount you may receive.
Keep the following in mind:
- Economic damages: This is the portion of your estimate tied to financial losses, such as medical bills, lost wages, and property damage. It helps you see how much of the estimated claim value comes from expenses and income losses that can be assigned a dollar amount.
- Pain and suffering: This represents the part of the estimate related to the injury’s physical and personal impact. The calculator shows a range because this amount is based on the injury severity and corresponding multiplier rather than a fixed expense.
- Estimated gross settlement: This is the overall settlement range produced by the calculator before anything is deducted. It gives you the figure to compare against the attorney fee, case expenses, and take-home amount that follow.
- Attorney fee: This shows how much of the estimated settlement may be paid to the attorney under the contingency percentage shown in your results. It shows the difference between the total estimated settlement and the portion that may go toward legal fees.
- Case expenses: This shows additional costs that may be taken from the settlement to handle the case. Because these expenses are separate from the attorney fee, they further reduce the amount that may remain for you.
- Estimated take-home: This shows what is left from the estimated settlement after the attorney fee and case expenses are deducted. In other words, it is the estimated amount you would receive from the settlement.
The report is meant to be read as a calculation from the estimated gross settlement down to the estimated take-home amount. Changes to the values higher in the breakdown can carry through to the attorney fee and the final amount shown at the bottom.
Frequently Asked Questions (FAQs)
Here are a few common questions about attorney fees and legal costs:
How Accurate Is the Attorney Fee Calculator?
The calculator provides an estimate based on the numbers and options you select. It can show how a contingency fee and case costs may affect a potential recovery, but it cannot predict the actual outcome of your claim.
The fee percentage and treatment of expenses should always be confirmed in your written fee agreement.
How Does an Attorney Retainer Work?
A retainer can refer to different types of advance fee arrangements, so it is important to read the agreement carefully.
For hourly legal work, a client may deposit money in advance, and the attorney may draw from those funds as fees are earned. Under Oklahoma ethics guidance, an attorney generally must return the unearned portion of an advance payment when representation ends.
Are Court Costs Included in Attorney Fees?
Not necessarily. Attorney fees pay for the lawyer’s legal services, while case costs can include filing fees, expert testimony, service fees, investigators, medical reports, and other expenses.
The Oklahoma Bar Association notes that costs and expenses are generally billed separately, although the exact arrangement depends on your agreement.
Can Attorney Fees Change During a Case?
They can, depending on the fee agreement. In a contingency case, the fee may increase if the case moves from settlement negotiations into a lawsuit or trial, where more legal work and preparation are required.
Oklahoma contingency agreements must state how the fee will be determined, including the applicable percentages.
Are Attorney Fees Negotiable?
Attorney fees may be negotiable, depending on the lawyer, the type of case, and the fee arrangement.
Before you sign the fee agreement, ask about the rate or percentage, how case expenses are handled, and whether the terms are flexible.
