Pick a calculator, choose a currency and theme, then copy the snippet. Paste it where you want the calculator to appear. The iframe resizes itself as readers change inputs, so nothing gets clipped.
The embed sets no cookies unless the visitor consents and records no sessions, so it drops into EU sites without adding a cookie banner of its own.

The Fire Planner runs month-by-month simulations, Monte Carlo, and backtesting. It is a full application, so it is not available as an embed. Link readers to it directly instead.
