FAQ
Does it include progressive rates?
No—it multiplies your flat rate. Korean residential tariffs are progressive (~120–307 KRW/kWh) plus base fees, so enter a higher-tier rate for a conservative estimate.
Where do I find the wattage?
On the nameplate or energy label. Compressor appliances (AC, fridge) often average below their rated wattage.
Why 210 KRW/kWh by default?
A rough mid-tier residential figure. Divide your bill's usage charge by kWh used for your own effective rate.
