Legal Fee Calculator
Legal matters can be expensive. This calculator helps you estimate the total cost of legal representation by combining attorney time charges with retainers, court filing fees, and other out-of-pocket disbursements. Enter your attorney's hourly rate, the estimated number of hours, any retainer already paid, court filing fees, and other costs. The calculator outputs the total billed hours, balance after retainer, and an overall cost estimate. All figures are estimates and actual costs will depend on your specific matter and jurisdiction.
Legal fee formula
Attorney Fees = Hourly Rate * Hours
Total Disbursements = Filing Fees + Other Disbursements
Total Cost = Attorney Fees + Total Disbursements
Balance After Retainer = Total Cost - Retainer Paid
The balance after retainer is the amount still owed to the attorney after applying the retainer. If the retainer exceeds the total cost, the attorney should refund the difference. This calculator does not account for contingency arrangements or flat-fee billing models.
Understanding legal billing
- Most attorneys bill in minimum increments, commonly 6-minute (0.10 hour) or 15-minute (0.25 hour) units.
- Retainers are held in a trust account and applied against billed time as work progresses.
- Court filing fees are set by the court and are non-negotiable (e.g., federal district court civil case filing fee is $405 as of 2024).
- Request monthly itemised statements so you can track charges and question unexpected items promptly.
- Some matters may qualify for limited scope representation, where the attorney handles only part of your case to reduce cost.
Legal fee calculator: frequently asked questions
What is a legal retainer fee?
A retainer is an upfront payment made to an attorney to secure their services. It is typically deposited into a trust account and drawn down as the attorney bills for their time. If the retainer is exhausted before the matter is resolved, the client must replenish it.
What is an attorney's hourly rate?
An hourly rate is the amount an attorney charges for each hour of work. Rates vary widely by practice area, seniority, and geographic location. According to the U.S. Bureau of Labor Statistics, the median hourly wage for lawyers was around $78 in 2023, but billing rates for experienced attorneys in major markets can exceed $500 per hour.
What are legal disbursements?
Disbursements are out-of-pocket expenses an attorney incurs on a client's behalf and then bills back. Common examples include court filing fees, process server fees, copying costs, expert witness fees, travel, and postage.
What is a contingency fee?
In a contingency fee arrangement, the attorney receives a percentage of any financial recovery rather than an hourly rate. Common in personal injury cases, the contingency percentage is typically 25% to 40% of the settlement or judgment. If the client does not recover anything, the attorney receives no fee (though disbursements may still be owed).
How can I reduce my legal fees?
Request itemised billing so you can review each charge, ask about a flat-fee arrangement for routine matters, prepare thoroughly before each meeting to reduce billable time, handle administrative tasks yourself where possible, and consider unbundled legal services where the attorney handles only specific parts of your matter.
