Calculate billed time and cost using standard legal billing increments (6, 10, or 15 minutes). See how rounding affects your legal bill.
Most law firms bill time in increments, typically 6 minutes (1/10 of an hour). This means a 2-minute phone call is billed as 6 minutes, and a 7-minute email is billed as 12 minutes. This rounding can significantly increase the effective cost of legal services.
This calculator shows how legal billing increments affect the actual billed time and cost. Enter the actual time spent and the billing increment to see the billed amount, the rounding overhead, and the effective hourly cost you are actually paying.
Understanding billing increments helps clients review invoices more critically, question excessive entries, and negotiate better billing terms with their attorneys.

Billed Increments = ceil(Actual Minutes / Increment) Billed Minutes = Billed Increments × Increment Cost = (Billed Minutes / 60) × Hourly Rate
Result: $80.00 billed for 8 actual minutes
Actual: 8 minutes. Rounded up: ceil(8/6) = 2 increments = 12 minutes. Cost: (12/60) × $400 = $80. You paid $80 for 8 minutes of work — an effective rate of $600/hour.
Consider an attorney who makes ten 3-minute phone calls in a day at $400/hour with 6-minute increments. Actual time: 30 minutes ($200). Billed time: 60 minutes ($400). The rounding doubles the cost.
Batch communications, request itemized invoices with task-level detail, ask about billing increments upfront, and periodically audit invoices against your own records of interactions.
The ABA Model Rules require attorneys to charge reasonable fees. Excessive rounding or padding of time entries can constitute an ethical violation. Clients who suspect overbilling should address concerns with the attorney or file a complaint with the state bar.
The most common increment is 6 minutes (0.1 hours). Some firms use 10-minute or 15-minute increments. A few modern firms bill in 1-minute increments. The larger the increment, the more you pay in rounding.
Studies show billing increments add 10–25% to total legal costs. The impact is greatest for short tasks like phone calls and emails, where a 2-minute call becomes a 6-minute charge.
Yes. More firms are adopting 1-minute billing, especially for routine communications. Negotiate the increment when you engage the attorney. Even moving from 15 to 6-minute increments can save significantly.
Attorneys often bill in tenths of an hour. Each tenth is 6 minutes. A 0.1 entry means 6 minutes (minimum), 0.2 means 12 minutes, 0.3 means 18 minutes, and so on. One full hour is 1.0.
Yes. If you see many 0.1 (6-minute) entries for tasks that likely took 1–2 minutes, discuss this with your attorney. Ethical rules require attorneys to bill for time actually spent, not to pad entries.
Block billing is when an attorney groups multiple tasks into a single time entry (e.g., "Research, drafted motion, made calls — 3.5 hours"). This makes it hard to evaluate whether the time was reasonable.
