An estimate calculator that does the math

The move · Give-the-rules, get-a-tool

If your pricing follows a rule, the AI can build a little calculator that does the math for you. You give it your numbers; it gives you a working tool.

You are building a price calculator for my [trade] business. My pricing works like this: [explain your rule — e.g. $X per room, plus $Y for stairs, minimum $Z]. Build a simple calculator where someone picks or types their options and sees the estimated price. Use only the numbers I gave you. Give me the complete tool as one file I can copy, paste, and use.

See the grounding line? That's the pro move: it pins the AI to your facts, and every good prompt carries one.

Your turn

You're a painter who charges by the room plus extra for high ceilings and a fixed trip fee. Write a prompt that turns those rules into a calculator where you enter the room count and get a price on the spot.

Remember: the AI sees only your prompt — not this page. If the situation isn't in your prompt, it doesn't exist.
