1. Utility Bill Savings (Electricity & Gas)
Utility bills are among the largest recurring household expenses. Korea's residential electricity uses a progressive rate system — the more you use, the higher the per-unit cost climbs.
Understanding Progressive Electricity Rates
| Tier | Usage (kWh) | Base Fee (KRW) | Rate (KRW/kWh) |
|---|---|---|---|
| Tier 1 | 0 – 200 | 910 | 120.0 |
| Tier 2 | 201 – 400 | 1,600 | 214.6 |
| Tier 3 | 401 – 1,000 | 7,300 | 307.3 |
| Over | 1,000+ | 7,300 | 709.5 |
A 70kWh difference (350 vs 420 kWh) can mean over 35,000 KRW more on your bill due to tier jumps.

Heating gas costs spike during winter (Nov–Mar). Lowering your thermostat by just 1°C saves about 7% on heating bills. Use away-mode instead of turning off the boiler completely.

Is that "sale" really a good deal? Always compare unit prices (per gram or per ml) rather than just looking at the sticker price. Bulk isn't always cheaper.
