Attorney Hourly Cost Calculator
Attorney billing is based on time tracked in minimum increments, typically 6 or 15 minutes. This calculator estimates the total billable amount by rounding actual time to the nearest increment, then applying the hourly rate and an optional overhead or soft-cost percentage. Use it to project costs for a legal matter based on time estimates for each task, or to verify a bill you have received. All figures are estimates and do not constitute legal or financial advice.
Attorney billing formula
Billed Increments = ceil(Actual Minutes / Increment Minutes)
Billed Hours = Billed Increments * (Increment Minutes / 60)
Attorney Fees = Billed Hours * Hourly Rate
Overhead = Attorney Fees * (Overhead % / 100)
Total Bill = Attorney Fees + Overhead
The ceiling function rounds up to the next full increment. For example, 245 actual minutes with a 6-minute increment: 245 / 6 = 40.83, rounded up to 41 increments. 41 * 6 = 246 minutes = 4.10 hours billed. At $400/hour: $1,640.00 in fees, plus 5% overhead ($82.00) = $1,722.00 total.
How to review an attorney bill
- Request itemised billing statements listing each task, date, attorney, time spent, and rate.
- Check that each time entry uses the billing increment specified in your engagement letter.
- Review for duplicate entries or tasks billed twice in different line items.
- Question vague entries such as "review file" or "telephone call" without specifics.
- Confirm that paralegal rates (lower than attorney rates) are applied to tasks appropriate for paralegals.
- Ask for an explanation of any overhead or soft-cost surcharge line items.
Attorney hourly cost calculator: frequently asked questions
How do attorneys bill for their time?
Most attorneys bill in minimum time increments, most commonly 0.10 hours (6 minutes) or 0.25 hours (15 minutes). Any task that takes less than the minimum increment is still billed at the full increment. For example, a 3-minute phone call at a 0.10-hour minimum is billed as 0.10 hours.
What is a typical attorney billing rate?
According to the U.S. Bureau of Labor Statistics, the median hourly wage for lawyers was approximately $78 in 2023. However, attorney billing rates (what is charged to clients) are higher than wages, and they vary enormously by practice area, seniority, and market. Rates range from under $150/hour for solo practitioners in smaller markets to over $1,000/hour for senior partners at large law firms in major cities.
What is the blended billing rate?
In matters involving multiple attorneys and staff (partners, associates, paralegals), a blended rate is a single average hourly rate that reflects the mix of staff working on the matter. Blended rates simplify billing and are often negotiated for large corporate clients. They are typically lower than a senior partner's individual rate.
What are soft costs vs hard costs in legal billing?
Hard costs (disbursements) are actual out-of-pocket expenses like court filing fees, expert witness fees, and travel. Soft costs are administrative overhead items such as photocopying, postage, and telephone charges. Some firms charge a flat overhead percentage (5% to 10% of fees) to cover soft costs; others itemise them separately.
How can I control attorney billing costs?
Negotiate a fixed fee or capped fee for predictable tasks, ask for a detailed budget before work begins, request monthly itemised bills to catch discrepancies early, prepare thoroughly for all meetings and calls, delegate routine tasks to paralegals where possible, and consider alternative fee arrangements such as phased billing or milestone payments.
