Meralco Bill Estimator (September 2026 rates)

Estimate your Meralco monthly residential bill using the September 2026 schedule of rates. Headline rate: ₱14.7424 / kWh all-in for the typical 200-kWh household (a ₱2,948.48 bill). Per-band rates change at higher or lower kWh totals due to distribution tiering.

September 2026 effective: Typical household (200 kWh band) total rate fell from ₱14.7833/kWh to ₱14.7424/kWh all-in (₱2,948.48 for 200 kWh), a ₱0.0409/kWh drop. A new ₱9.5-billion AWAT refund (₱0.5861/kWh) is now layered on top of the existing refund (₱0.4278/kWh). Distribution charge for residential customers has been frozen since August 2022.

From your latest bill: kWh used this billing month. Meralco bills monthly; use your most recent 200–500 kWh reading as a starting point.

For General Service A/B and commercial customers, rates differ and are not modeled here.

Disclaimer: All component rates above are VAT-EXCLUSIVE pass-throughs on the source schedule; the headline 14.7424/kWh figure in Meralco publicity already includes VAT. The calcBill() function in src/lib/meralco.ts interpolates the RPT charge and VAT across Meralco's 15 published sample kWh points so the total reproduces the printed sample-bill amounts to the centavo (₱2948.48 at 200 kWh). Local Franchise Tax (LFT) varies per city, and historic pass-through under-recoveries can briefly inflate the bill in some months. Visayas and Mindanao electric cooperatives are not modeled here.

How we compute this

  1. Pick the distribution band for your kWh consumption.
  2. Sum the 17 per-kWh pass-through components (generation + transmission + ancillary + system loss + LRA + SCS + AWAT refunds + UCs + RPT adj + LFT adj + UC-EC + FIT-All + PF adj + others).
  3. Multiply by kWh. Add fixed monthly supply + metering charges and the local energy tax.
  4. Add interpolated RPT amount and interpolated VAT — both piecewise-linear across Meralco's published sample bills.
  5. Apply the senior citizen discount if applicable (5%, ≤100 kWh, pre-VAT).

Frequently Asked Questions

Why is my actual bill ₱ higher than this estimate?

This tool uses the September 2026 residential rates. Your bill includes (a) any generation passthroughs Meralco recovered prior to the month, (b) VAT, (c) universal charges from NGCP and other generators, and (d) taxes that vary by city (Local Franchise Tax). If you have a non-residential service (General Service A/B or General Power), the calculator does not apply — the rates differ. See the bill line items labeled "LFT Adj" and look for any retroactive AWAT adjustments.

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 distribution charge will rise by the same amounts the refunds were subtracting.
