Korea Electricity Bill Calculator

Korean electricity is billed on KEPCO's progressive rate system, where each kilowatt-hour gets more expensive the more you use. That makes the final amount hard to predict, and it often arrives as an unpleasant surprise at the end of the month. This app turns an energy meter you already have into a live electricity-bill tracker. It reads your ongoing consumption and, following your meter-reading day and the seasonal progressive rates, continuously estimates what the current billing period will cost. You always know how much you have spent so far, how much today alone has added, what to expect by the end of the period, and when you are about to cross into a pricier tier, so you can adjust your usage in time and avoid bill shock. Beyond residential progressive rates (low and high voltage), it also supports general, educational, industrial, agricultural and off-peak contract types including time-of-use pricing with KEPCO's Saturday and holiday metering rule, and applies large-family, newborn-household and welfare (e.g. national-merit) discounts.
