Attorney billing math

What this calculation answers

An attorney billing total answers a direct question: how much client-facing legal time is chargeable under the fee agreement. The core inputs are billable hours, the applicable hourly rate, and any billing increment used by the firm. For U.S. legal work, amounts are normally stated in U.S. dollars because U.S. coins and currency, including Federal Reserve notes, are legal tender for debts, public charges, taxes, and dues.

The calculation also separates billable time from billed time. Billable time is the time eligible to charge. Billed time is the amount that remains after attorney review, write-downs, non-billable task exclusions, and invoice edits. That distinction matters when a partner reduces a draft bill for client relationship reasons or when a contract excludes internal meetings, training, or administrative work from client charges.

Apply rates before adjustments

Start with the timekeeper or matter rate that the client accepted. For U.S. lawyers, ABA Model Rule 1.5 requires the scope of representation and the basis or rate of fees and expenses to be communicated in writing for new client-lawyer relationships, subject to the rule's limited low-cost exception. Use that written basis before applying discounts, caps, taxes, or payment terms.

For example, a matter includes 16 partner hours at $340 per hour and 12 associate hours at $195 per hour. The partner amount is $5,440.00, and the associate amount is $2,340.00, so the pre-adjustment attorney billing total is $7,780.00. If the supervising attorney writes down $480.00 before invoicing, the billed fee amount becomes $7,300.00 before any jurisdiction-specific tax or reimbursable expense treatment.

Check tax and timing separately

The United States has no federal VAT/GST or national sales-tax rate for billed professional time. Sales tax treatment is state and local, with different percentages on different goods or services, and some services are not taxed. A U.S. attorney billing calculation therefore needs a jurisdiction-specific tax input only when the legal service is taxable under the applicable state or local rule.

Payment timing is a separate issue from fee calculation. For federal-agency vendor invoices, Prompt Payment rules generally use the contract date, accepted discount terms, an accelerated-payment rule, or 30 calendar days after receipt of a proper invoice. For invoices paid less than 31 days late, Treasury calculates simple daily interest as principal times the annual Prompt Payment rate divided by 360 times days late.

Know when calculation is enough

A one-off calculation is enough when you have a short matter, one rate, approved hours, no write-downs, and no taxable service input to apply. It gives a quick draft invoice total and helps you spot obvious errors, such as using the wrong rate or including time marked internal, administrative, or otherwise non-billable under the client agreement.

A managed workflow is better when several timekeepers, matter rates, approvals, write-downs, and invoice handoffs are involved. Everhour Reporting can group logged time by member, task, project, client, billable status, and date range, then export reports in CSV, Excel/XLSX, or PDF. That creates a reviewable record before billing instead of rebuilding the calculation from scattered notes.

Frequently Asked Questions

What entries belong in an attorney billing total?

Include approved legal work that the fee agreement treats as billable, priced at the written hourly rate or other agreed basis. Exclude non-billable administration, training, internal review that the client agreement excludes, and any time the reviewing attorney writes off before billing. Keep reimbursable expenses separate unless the invoice format combines fees and expenses.

Should a legal bill use a partner rate or an associate rate?

Use the rate assigned to the person who performed the work unless the engagement letter or client billing policy states a different method. A blended matter rate is valid only when the client agreement supports it. Do not average partner and associate rates after the fact if the written fee basis names separate timekeeper rates.

Where do sales tax or gross receipts tax inputs fit?

Apply a state or local tax input after calculating the fee amount only when the applicable jurisdiction taxes that service. The United States has no federal VAT/GST or single national sales-tax rate for billed professional time. Some jurisdictions tax services differently, so a U.S. attorney billing total should keep the tax field separate from the fee subtotal.

What billing mistake changes the total fastest?

The fastest error is applying the wrong rate to the right hours. For example, pricing associate work at a partner rate overstates the invoice even if every time entry is accurate. The second common error is treating draft billable time as final billed time before partner review, write-downs, and client billing rules have been applied.

How should federal-agency payment timing be handled?

For federal-agency vendor invoices, the Prompt Payment due date is based on the contract date, accepted discount terms, an accelerated-payment rule, or 30 calendar days after receipt of a proper invoice. If a qualifying invoice is paid late, interest is calculated separately from the attorney billing total, using the applicable Prompt Payment rate and days late.

How does Everhour Reporting support attorney billing review?
