Enter an appliance's wattage, daily usage hours, and your current progressive tariff tier to estimate its power usage and the cost it adds to your monthly bill.
Enter the details above to estimate power usage and cost.
Estimated using South Korea's KEPCO (Korea Electric Power Corporation) residential low-voltage progressive tariff (reference rates, 2021 revision), so amounts are shown in Korean won (₩) regardless of site language. Actual bills vary with seasonal summer tiers, the minimum-usage discount, welfare discounts, and total household usage across all appliances — treat this as a rough reference, not an actual bill.
South Korean residential electricity uses a progressive (tiered) pricing structure — the more you use in a billing period, the higher the per-kWh rate on the additional usage, unlike a flat per-unit price. This tool estimates your daily and monthly power usage from an appliance's wattage and usage time, then estimates the monthly bill range using KEPCO's (Korea Electric Power Corporation) residential low-voltage progressive rate table.
Daily and monthly kWh usage is computed from wattage × hours used, converted to kilowatt-hours. The bill estimate applies KEPCO's tiered rate table, where usage above each tier threshold is billed at that tier's higher per-kWh rate — the tool shows a range because the minimum reflects only the energy charge, while the maximum adds the basic monthly fee, VAT, and the electricity industry fund typically included on an actual bill.
