Monthly Legal Budget Calculator
Set a monthly legal budget from annual revenue and a selected percentage.
How this tool works
Annual budget = revenue × selected percentage; monthly budget = annual budget ÷ 12.
What the result does not tell you
The result is a mathematical planning estimate based only on the values you enter. It does not predict a legal outcome, establish a reasonable attorney fee, determine eligibility, or interpret a contract, court rule or statute.
Before hiring a lawyer
- Ask what services are included in the quoted fee.
- Confirm whether filing fees, experts, travel or other costs are separate.
- Request the fee arrangement in writing.
- Ask who will perform the work and how communication is billed.
Use the estimate as a planning range, not a quote
A calculator can make the arithmetic transparent, but legal billing depends on the engagement agreement and the amount of work actually required. Use the result to prepare questions for counsel: what assumptions are included, which expenses are separate, when fees are earned, and which events could change the budget.
Three scenarios worth testing
Questions to take to the fee discussion
- Is the number I entered an attorney fee, a court cost, or a third-party expense?
- Can the scope change without a new written agreement?
- How often will I receive billing or budget updates?
- What happens to unused retainer funds, if any?
- Which costs are likely but not included in this estimate?
Save the assumptions you used. If a lawyer gives you a different estimate, compare the underlying scope rather than only the total amount.
Use the result as a planning range
The Monthly Legal Budget Calculator is designed to make a fee or cost structure easier to understand before you compare engagement terms. Change the inputs to test different scenarios rather than treating one output as a quoted legal price.
Worked-example checklist
| Check | Why it matters |
|---|---|
| Fee basis | Confirm whether the lawyer charges hourly, flat, retainer or contingency fees. |
| Included services | Clarify which calls, meetings, drafting and court appearances are included. |
| External costs | Filing fees, experts, service, travel or records may be additional. |
| Scope changes | Ask what happens to the budget if the matter becomes contested. |

FAQ
Is the calculator a legal fee quote?
No. It performs arithmetic using your inputs and cannot know the lawyer's engagement terms, jurisdiction, case complexity or future work.
Why can actual legal costs differ so much?
Legal work is fact-specific. Disputes, hearings, discovery, expert work, urgent deadlines and additional parties can materially change the amount of attorney time required.
How to use the estimate responsibly
A calculator is most useful when the inputs come from a real engagement letter, quote, court notice or planning assumption that you understand. Run more than one scenario rather than treating one result as a prediction. For example, test a higher number of attorney hours, additional case expenses or a different fee percentage to see which inputs have the greatest effect on the total.
The result should be used to prepare questions for counsel. Ask which assumptions are realistic, which costs are outside the lawyer's control and what events could cause the scope of work to change. A transparent estimate is a starting point for budgeting, not a substitute for a written fee agreement.
Questions to confirm with counsel
- Which services are included in the stated fee?
- Are calls, emails, paralegal time or document review billed separately?
- Which court, filing, expert or administrative costs are additional?
- Will I receive periodic billing or budget updates?
- What happens to unused retainer funds, if applicable?
Legal rules vary by jurisdiction. We use primary or authoritative sources for material procedural and regulatory statements and recommend checking the current rule that applies to your location.
