Law Firm Fee Calculator

The form your customers fill out

A live calculator, not a static quote request. Your customer enters their details and watches the number update on the spot, which is what turns a browser into a booked job.

What it calculates

Potential clients see a live fee range as they describe the matter, so more of them book the consult
Keeps your real fee schedule: flat fees by matter type, complexity multipliers, and court-cost add-ons
Handles practice areas on separate tabs, from estate planning to immigration to business formation
Adjust flat fees or add a practice area later by asking Claude, no rebuild
Backtest against closed matters so the estimate reflects what your firm actually billed

Why it closes more deals

⚡

A live number closes deals

Customers who see a real estimate the second they enter their details are far likelier to book than ones told to call for a quote. The number is the hook.

📊

Runs your most complex spreadsheet

Multi-tab workbooks, lookup tables, tiered rates, conditional line items, the lot. If the math runs in Excel, CalcForms runs it behind a clean form.

🔁

Update it by chatting

Prices move. Ask Claude to change a rate, add an option, or insert a step and the live form updates in seconds. No developer, no redeploy.

🎯

Backtest before you publish

Run your last 20 real jobs through it and tune the formula until the live estimate matches what you actually charge. Ship it once it lines up.

How this form was built

No template builder and no code. One message to Claude with the CalcForms connector switched on:

✦ Claude with the CalcForms connector

Here is my firm's flat-fee schedule. Each matter type has a base flat fee, complexity applies a multiplier, and some matters add state filing fees from a lookup table. Build a fee estimator that shows prospective clients a low-to-high range and collects their contact info.

Done. I built Law Firm Fee Calculator with your pricing and deployed it to forms.badabingapp.cc. The math runs server-side and every submission is saved with the inputs and email. Want to add a field or change a rate? Just tell me.

Example run: A founder selects business formation, standard complexity, California, 2 members, filing fees included. The calculator returns an estimated $1,500 to $2,100 range and sends the firm a qualified intake with the matter details.

Formulas it supports

Base fee = VLOOKUP(matter_type, fee_schedule, 2, FALSE)
Complexity factor = IF(complexity="Complex", 1.5, IF(complexity="Standard", 1.0, 0.8))
Filing cost = IF(include_fees="Yes", VLOOKUP(state, filing_table, 2, FALSE), 0)
Low estimate = Base * Complexity_factor + Filing_cost
High estimate = Low_estimate * 1.4

FAQ

Can it show a fee range instead of one exact number?

Yes. Most firms prefer a low-to-high range for ethics and expectation-setting, and the calculator computes both from your base fee and complexity factor.

Does it handle different practice areas?

It does. Each practice area can live on its own tab with its own fee schedule, and the matter type drives which logic runs.

Can I add state filing fees automatically?

Yes. A lookup table maps jurisdiction to filing cost, and you can toggle whether those costs are included in the estimate.

How do I keep fees current as I change my schedule?

Tell Claude the new flat fees or multipliers in chat. The live estimator updates without any rebuild.
