Put calculators where they're most relevant:
- Mortgage calculator on home buying articles

2. Add Context
Don't just drop in a calculator. Add helpful text:
- Explain what the calculator does

Our calculators are mobile-friendly, but check:
- Use max-width: 100%
in the iframe style - Test on multiple devices

4. Loading Performance
Our calculators load asynchronously with loading="lazy", so they won't slow down your page. The script loads only when the user scrolls to the calculator.
