Source: PUCSL approved tariff table for a 30 day billing cycle, effective from 2026-04-01. The previous comparison tariff used here is the table effective until 2026-03-31. CEB category coverage mirrors the official CEB calculator list, and LECO mode follows the five categories shown on the revised LECO bill calculator page. This version treats the calculated charge as VAT-inclusive and adds SSCL at 2.5% on top. Fuel adjustment and agreement-specific rooftop-solar export tariffs are not included here.

FAQ

How do I calculate an electricity bill in Sri Lanka?

Choose the tariff category, enter the relevant units or meter-reading inputs, and the calculator applies the matching tariff logic plus the taxes modeled on this page.

Does this calculator support both CEB and LECO bills?

Yes. You can switch between CEB and LECO categories and estimate the bill using the supported tariff paths shown in the tool.

Does the electricity bill calculator use the new April 2026 tariff?

Yes. The estimate uses the approved tariff effective from April 1, 2026 and compares it against the tariff used until March 31, 2026. As of 2026-05-10, the later PUCSL extraordinary review is still treated here as a consultation-stage item rather than a newer approved tariff.

Can I estimate solar billing impact here?

Yes. For supported unit-based categories in both CEB and LECO mode, you can turn on a solar scheme and estimate the bill effect of import units, export units, carry-forward units, and export-credit rate assumptions.
