Freelance Rate 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

Clients get a live project quote as they pick scope and turnaround, so more of them book you
Keeps your real pricing logic: deliverable tiers, revision rounds, and rush surcharges
Prices different service types on separate tabs, from design to copy to development
Raise your day rate or add a package later by asking Claude, no rebuild
Backtest against past projects so quotes reflect what you actually charged

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 freelance pricing spreadsheet. Each project type has a base rate by size tier, extra deliverables add a per-unit fee, revisions beyond two are billed per round, and rush jobs add 40%. Build a calculator that shows clients an instant project quote.

Done. I built Freelance Rate 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.

Build this exact form

CalcForms is a connector you add to Claude once. After that you build and edit forms just by chatting.

Add CalcForms to Claude. Open the Add custom connector dialog, name it Calcforms, and paste https://forms.badabingapp.cc. One time, about 60 seconds.
Paste the prompt below. Claude builds the form, wires in your math, and hands you a live URL.
Share it, then tweak by chatting. Put it on your site or send the link. Change a rate or add a field later just by asking.

Copy this prompt into Claude

"Here is my freelance pricing spreadsheet. Each project type has a base rate by size tier, extra deliverables add a per-unit fee, revisions beyond two are billed per round, and rush jobs add 40%. Build a calculator that shows clients an instant project quote."

Example run: A startup picks website design, medium size, 4 deliverables, 2 revisions, rush turnaround. The calculator returns about $5,200 and sends the freelancer a lead with the brief already captured.

New to connectors? A connector (an MCP server) is a secure link between Claude and an app. The CalcForms connector lets Claude build, deploy, and update real calculator forms for you, all from the chat window.

Formulas it supports

Base = INDEX(rate_grid, MATCH(project_type, types, 0), MATCH(size, sizes, 0))
Deliverable fee = MAX(0, deliverables - included) * per_deliverable
Revision fee = MAX(0, revisions - 2) * per_round
Subtotal = Base + Deliverable_fee + Revision_fee
Quote = IF(turnaround="Rush", Subtotal * 1.40, Subtotal)

FAQ

Can it price different services with different rates?

Yes. An INDEX/MATCH grid maps project type and size to the right base rate, so design and development each price correctly.

Does it charge for extra revision rounds?

It does. Anything beyond your included rounds adds a per-round fee, so unlimited-revision scope creep does not eat your margin.

Can I switch from hourly thinking to project pricing?

Yes. Build the calculator around scope tiers and deliverables, and clients see a clean project quote instead of an hourly guess.

How do I update my rates as I get more experienced?
