ℹ️ Calculation Methodology
- Consumption blocks are adjusted according to the billing period where the applicable tariff uses 30-day consumption blocks.
- Fixed monthly charges are not prorated.
- For meter-reading mode, Units = Current Reading − Previous Reading.
- For ToU tariffs, Peak, Day and Off-Peak consumption are calculated separately.
- Applicable maximum-demand charges are calculated using the entered kVA demand.
- SSCL is calculated as: Subtotal × 2.5 ÷ 97.5.
- Final Bill = Subtotal + SSCL.
Tariff basis: PUCSL approved tariff table effective
from 11 May 2026. This calculator is an estimate and
may differ from an actual CEB/LECO bill because of
billing adjustments, rounding, meter conditions and
other applicable charges.
