Meralco Bill Estimator (August 2026 rates)

Estimate your Meralco monthly residential bill using the August 2026 schedule of rates. Headline rate: ₱14.7833 / kWh all-in for the typical 200-kWh household — the same figure Meralco publishes, reproduced here from their own sample-bill table.

August 2026 effective: Typical household (200 kWh band) total fell from ₱14.8261/kWh to ₱14.7833/kWh (₱2,956.65 for the month), a drop of about ₱9. A new ₱9.5-billion AWAT refund (₱0.5861/kWh) is layered on top of the existing refund (₱0.4278/kWh), partly offset by higher transmission/ancillary and tax charges. Distribution charge for residential customers has been frozen since August 2022.

From your latest bill: kWh used this billing month.
For General Service A/B and commercial customers, rates differ and are not modeled here. Lifeline customers are not modeled.

RPT charge and VAT are shown as published per-kWh equivalents at each consumption level (they amortize fixed charges, so they drift slightly with usage). Local Franchise Tax assumed at the published average; it varies per LGU.

Disclaimer: This estimator reproduces Meralco's published August 2026 residential sample-bill table (50–5,000 kWh). Verify against your actual bill line items — Local Franchise Tax varies per city, and passthrough under-recoveries can briefly inflate some months. Visayas and Mindanao electric cooperatives are not modeled here.

How we compute this

  1. Pick the distribution band for your kWh consumption (≤200 / 201–300 / 301–400 / >400).
  2. Sum the per-kWh pass-through components (generation, transmission, ancillary, system loss, lifeline rate adjustment, SC subsidy, AWAT refunds, regulatory fees, universal charges, UC-EC, FIT-All, power factor adj.) plus the band-specific distribution charge.
  3. Add fixed monthly supply (₱16.38) + metering (₱5.00) charges, the RPT charge, and the local energy tax (first 650 kWh free).
  4. Apply the senior citizen discount if applicable (5%, pre-VAT, ≤100 kWh per ERC rules).
  5. Add VAT as published per-kWh equivalents for your consumption level.

Frequently Asked Questions

Why is my actual bill different from this estimate?

This tool reproduces Meralco's published August 2026 residential sample bills (200 kWh → ₱2,956.65). Your actual bill can still differ due to local franchise tax varying by city, generation passthrough adjustments specific to your billing month, senior/lifeline discounts you claim, or metering-period misalignment.

What are the two AWAT Refund/Collect lines on my bill?

These are Meralco refunds back to consumers because the Energy Regulatory Commission (ERC) approved a refund in the difference between Meralco's Actual Weighted Average Tariff (AWAT) and its approved distribution tariff. Refund/Collect 1 (₱0.4278/kWh) is the older ongoing refund; Refund/Collect 2 (₱0.5861/kWh) is a new ₱9.5 billion refund split across 6 months starting August 2026. Both run on the bill each month until the recovery period ends.

When do AWAT refunds end?

Refund/Collect 1 has been ongoing; the ERC decides the cessation based on whether the AWAT vs. approved rate gap closes. Refund/Collect 2 expires around early 2027 once the ₱9.5B total is recovered. After that, your bill will rise by roughly ₱1.01/kWh combined.
