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:

Build a law firm fee calculator for clients. Inputs: type of matter, how involved it is, and the client state.

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.

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.
