Client Fee Estimate Calculator

Clients rarely object to a fee because it is large. They object because it arrived without explanation, or because it did not match what they were told. Both are presentation problems, and both are solved by showing the construction.

This calculator produces an estimate broken down by who does the work, with expenses separate and the allowance for undefined scope stated rather than hidden. It is the version worth putting in front of a client.

This tool performs arithmetic on the values you enter. It does not provide legal advice and does not create an attorney-client relationship.

The blended rate is the single number clients remember. Shifting work to the right timekeeper level moves it more than any rate change.

A contingency allowance covers scope that is likely but not yet defined. State it separately in the estimate so the client can see what it is for.

Showing a client the effect of a staffing choice on the price.
Comparing an hourly estimate against a proposed fixed fee.
Answering a client who has asked why a matter costs what it does.

Worked examples

Every figure below is produced by running this calculator against the example inputs, so the numbers always match the tool.

A defined matter

10 partner hours at $600, 35 associate hours at $320, 25 paralegal hours at $150, $1,800 of expenses, 12% allowance.

Total estimate: $25,264
Blended rate: $299.29
Contingency allowance: $2,514

The same matter, leaner staffing

Partner involvement halved with the work moved down a level.

Total estimate: $21,792
Blended rate: $255.00
Partner share: 16.81%

Transparency is cheaper than explanation

An estimate that shows hours by level, expenses separately and an explicit allowance answers most of the questions a client would otherwise ask. It also makes any later variance a conversation about a specific line rather than about the total.

The blended rate is the figure clients actually compare between firms, and it is decided by staffing rather than by the rate card. Showing it puts you in control of that comparison instead of leaving it to inference.

An allowance is not padding

Hiding uncertainty by inflating the hours makes the estimate look expensive and makes any later conversation harder, because there is nothing specific to point at.

Stating an allowance does the opposite. It signals that the estimate has been thought about honestly, gives the client a number they can question, and gives you a defined thing to draw on when the scope moves.

Methodology and assumptions

What this calculator does, and what it deliberately does not do.

Professional fees are hours × rate at each timekeeper level. The contingency allowance applies to fees only.
Tax applies to fees, allowance and expenses combined; which components are taxable differs by jurisdiction.
The blended rate divides professional fees by total hours.
The tool performs arithmetic or date counting on the values you enter. It does not interpret a rule, a statute or a contract.
Nothing you type is transmitted or stored - the calculation runs entirely inside your browser.

This website provides general informational and productivity tools and does not provide legal advice or create an attorney-client relationship.

The date and deadline tools count days exactly as you instruct them. They do not interpret court rules, statutes of limitation, filing requirements or any other legal authority, and they do not know the rules of your jurisdiction.

Always verify any date, fee, or calculation against the governing rule, the court calendar and your own professional judgement. If you need legal advice, consult a lawyer licensed in your jurisdiction.

Frequently asked questions

Should the client see the timekeeper breakdown?

Usually yes. It explains the price and makes any staffing change visible and discussable rather than a surprise on an invoice.

What if the estimate is more than the client expected?

That is a scope conversation, not a pricing one. Reducing the estimate without reducing the work simply moves the difference onto the invoice.

Is an estimate binding?

Generally not, though some jurisdictions require notice when an estimate is going to be exceeded. Check the rules where you practise and state the position in the engagement letter.

Should expenses be included in the headline number?

Either way works if the engagement letter is explicit. Keeping disbursements separate avoids the fee estimate moving with third-party costs you do not control.
