How Korean Water Bills Are Calculated
Water bills in Korea consist of a water supply charge and a sewer charge. The supply charge applies a tiered (progressive) rate: higher consumption tiers carry a higher per-unit price. The sewer charge is calculated separately based on supply usage. VAT (10%) is added to the supply portion.
This calculator uses average residential rates from major Korean cities (Seoul base rates). Actual charges vary by region and utility provider. Use this as an estimate for budgeting purposes.
Water Conservation Tips
- Use a cup when brushing teeth — saves up to 80% vs. running tap
- Shorten showers by 1 minute — saves approximately 10–12 liters
- Run full laundry loads instead of small, frequent cycles
- Fix leaks promptly — a dripping faucet can waste hundreds of liters per day
Frequently Asked Questions
In most Korean regions, water bills are issued every two months. Some areas issue monthly bills. Check with your local utility provider.
Turn off all water usage inside your home and watch the meter for movement. If the meter is still moving, you likely have a leak in the pipes. Contact your building manager or a plumber.
