# Transformer loss and payback calculator

Compare energy losses, annual operating cost and optional simple payback for two transformer designs.

## Inputs

Verified no-load P0 and load Pk losses (W), loading, operating hours, electricity price and optional investment difference.

## Results

Energy and cost differences, CO₂ estimate and simple payback when the inputs support it.

## Interpretation and limits

Load loss scales with the square of loading. Use comparable ratings and test conditions. Simple payback is not discounted cash flow; energy price and utilization assumptions control the result.
