Electricity Bill Calculator for Sri Lanka

Calculating your electricity bill in Sri Lanka requires understanding the latest tariff structure implemented by the Ceylon Electricity Board (CEB) and Lanka Electricity Company (LECO). As of 2025, Sri Lanka uses a progressive tariff system where the unit price increases with higher consumption. The first 30 units (kWh) are charged at the lowest rate, with subsequent blocks (31-60, 61-90, 91-120, 121-180, and above 180) having progressively higher rates. Additional charges include a fixed monthly service fee, fuel adjustment charge (which varies monthly), and taxes. Our calculator simplifies this complex calculation by automatically applying the current rates and additional charges based on your monthly consumption.

The electricity rates differ slightly between CEB and LECO customers, and there are special tariffs for religious institutions and small businesses. With frequent adjustments to the fuel surcharge and occasional revisions to the base tariff, manually calculating bills has become increasingly difficult. Our calculator stays updated with the latest rates and includes all applicable charges to give you the most accurate estimate. Understanding your bill breakdown can help identify opportunities to reduce consumption during peak rate periods or consider alternative energy options like solar power for high-consumption households.
