Advanced Transformer Calculator - Voltage, Turns Ratio & Efficiency Tool

Use our free Advanced Transformer Calculator to quickly compute turns ratio, voltage conversion, impedance matching, and transformer efficiency. Perfect for electrical engineers, students, and DIY enthusiasts. Mobile-friendly, accurate, and easy to use!

The Advanced Transformer Calculator is a powerful, user-friendly tool designed for electrical engineers, technicians, students, and hobbyists. It helps you quickly compute key transformer parameters such as turns ratio, voltage conversion, impedance matching, power efficiency, and more—all in one place. Whether you’re designing circuits, troubleshooting transformers, or learning electrical theory, this tool provides fast, accurate calculations with a clean, intuitive interface.

  • Calculate turns ratio (primary to secondary windings)

  • Determine voltage conversion (step-up or step-down transformers)

  • Find current & power values (input/output calculations)

  • Compute impedance matching (for optimal power transfer)

  • Measure efficiency & losses (core loss, copper loss, total efficiency)

Simply enter your known values, and the calculator instantly provides results with precise formulas displayed for reference.

✔ Multiple calculation modes (Basic, Turns Ratio, Impedance, Efficiency)
✔ Interactive tooltips explain each parameter for beginners
✔ Auto-compute missing values (e.g., find secondary current if primary current is known)
✔ Real-time results with clear, formatted outputs
✔ Formula display for educational & verification purposes

For faster navigation:
