How does the Isotope Decay Calculator work?

Input isotope, half-life, and time elapsed Then: Calculate remaining nuclei and activity Then: Show decay curve.

Can you give an example of how to use the Isotope Decay Calculator?

Example: Input ¹⁴C: t₁/₂ = 5730 years, after 11,460 years → 25% remains gives a result of After 3 half-lives: 12.5% remains.

Is the Isotope Decay Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.

How accurate is the Isotope Decay Calculator?

Our Isotope Decay Calculator uses verified mathematical formulas and is accurate to multiple decimal places. Results are calculated in real-time using the same methods used by professionals.
