Your time is worth

$/hr

Overhead per unit

Share of rent, tools, ops spread across each sale. Optional.

Your target

This whole tool is about 200 lines of code and zero AI calls — it's pure math. That's the point: most tools you reach for are simpler than they look. Once you can see the logic, you can build it. Here's the exact recipe.

See the one formula that runs everything

The entire tool hangs on a single line of math. Price isn't cost plus a markup — it's cost divided by what's left after your margin. Internalize this and the rest is just inputs and display.

the core formula

// true cost = everything it takes to deliver one
trueCost = directCost + (hours × rate) + overhead

// price that clears your target margin
price = trueCost / (1 - margin/100)

// e.g. $40 cost at 50% margin → $40 / 0.5 = $80

Have AI scaffold the page for you

Don't hand-write the HTML. Paste this prompt into Claude or any builder. It hands you the whole working file — then you tweak. This is "thinking in AI": you bring the logic, AI brings the labor.

paste this prompt

Build me a single-file HTML pricing calculator.

Inputs: product name, sales model (per-unit / hourly /
subscription), direct cost, hours, hourly rate, overhead,
target margin %, and expected monthly volume.

Logic:
  trueCost = directCost + hours*rate + overhead
  price    = trueCost / (1 - margin/100)
  show profit per sale, % markup, breakeven count,
  and projected monthly + annual profit.

Also output an optional 3-tier version: Lite at 0.7x,
Core at 1x (the anchor), Premium at 1.6x.

Style: warm ivory background, black text, burnt-orange
accents, serif headers, monospace labels. Clean + editorial.
No backend, no API calls. Pure JavaScript math.

Make it yours

Swap the tier multipliers to match how you actually sell. Change the margin guidance for your industry. Add a field you wish it had. The version you bend to fit your own business is the one that proves you can build.

From one tool to the reflex

One tool is a trick.
The reflex is the moat.

You just built a pricing calculator. Cool. But the real unlock is the moment a problem shows up and your brain goes "I could build something for that" instead of "ugh." That reflex doesn't come from one build — it comes from doing it over and over until it's automatic. That's the whole course.
