Get a Calculator for Your Website

Your customers type things like "how much does a plumber cost" into Google every day. A little calculator on your site answers that question, and gets you found on Google. Here's how to add one in 10 minutes. No tech skills needed.

First: what's a "calculator page"?

It's a little interactive tool on your website. The customer types in a few things (the size of their job, their budget, their zip code) and it gives them an answer. A price estimate, a quote, a timeline, or a comparison.

Think of a tradie site with an "emergency callout cost calculator," a mortgage broker with a "repayments calculator," a gym with a "personal training cost calculator." Simple. Useful. Takes 2 minutes to use.

Why bother putting one on your site?

📈
Google traffic People search "how much does X cost" every day. Calculator pages rank for those searches and bring you free traffic.
📞
More enquiries Once someone sees a rough number, they're far more likely to pick up the phone or fill in your form.
🤝
Trust & authority Showing real numbers makes you look like the expert. Customers pick the business that's clear and upfront.

3. Build it automatically (advanced)

Pro

Skip the copy-paste. Add your Anthropic API key and this tool builds the calculator for you. It generates the file, lets you preview it, and downloads it ready to upload. Your key never leaves your browser. Costs ~$0.05 to $0.15 per build on your own account.

New to API keys? Read this first (2 min)

What's an API key? Think of it as a personal access code for Claude's "engine." It lets this tool generate code on your behalf using your own Anthropic account — different from the chatgpt.com / claude.ai chat interface.

How to get one (5 min):

  1. Go to console.anthropic.com and sign up.
  2. Add $5 credit (Settings → Billing).
  3. Settings → API Keys → Create Key. Copy the key (starts with sk-ant-) and paste below.

Don't want to mess with API keys? Use the free downloadable Claude skill instead — paste it into a Claude Project and run there.

🔒 Your key never leaves your browser. Stored locally only (if you tick the box) and used to call Anthropic directly from your device.
