Frequently Asked Questions

What is a progressive electricity rate?

A progressive rate means the unit price increases as usage rises. Residential electricity in Korea has 3 tiers: 0–200 kWh, 201–400 kWh, and over 400 kWh.

Are summer and winter electricity rates different?

Yes. Summer (Jul–Aug) and winter (Dec–Feb) have higher energy demand and may carry seasonal surcharges. Check your KEPCO bill for details.

Can the calculated amount differ from my actual bill?

Yes. This calculator uses the basic progressive rate structure. Welfare discounts, seasonal charges, and fuel cost adjustments are not included, so the actual bill may differ.
