Electricity Calculators for MEPCO Consumers
Pick a job below and follow the suggested sequence. Every result is an estimate from inputs you provide and published NEPRA tariff concepts — not a live official bill and not affiliated with MEPCO.
Understand your bill
Turn meter readings into units, then estimate slab or ToU cost before the printed invoice.
Suggested path: Meter reading → Bill calculator (or Peak/off-peak) → Budget planner
Meter Reading Calculator
Find consumed units from previous and current readings, plus a daily average.
Open toolBill Calculator
Estimate domestic slab energy cost, fixed charges, FPA, QTA and GST from units you enter.
Open toolPeak / Off-Peak Calculator
Separate peak and off-peak kWh to approximate a Time-of-Use bill.
Open toolEnergy Budget Planner
Turn a rupee budget into a daily unit limit using your assumed blended rate.
Open toolReduce usage
See which appliances drive units, convert energy quantities, then set a daily ceiling.
Suggested path: Appliance cost → Unit converter → Budget planner
Solar & backup
Size a rough array, estimate inverter runtime, and check conversion losses for hybrid setups.
Suggested path: Solar size → UPS backup → AC↔DC → Wire size
Solar Size Calculator
Convert monthly units into a planned inverter kW and panel count with a loss buffer.
Open toolUPS Backup Calculator
Approximate inverter runtime from battery Ah, voltage, DoD and load watts.
Open toolAC ↔ DC Calculator
Estimate usable power after inverter or charger conversion losses.
Open toolWire Size Calculator
Suggest copper wire mm² / AWG from amps, voltage, length and voltage-drop limit.
Open toolElectrical formulas
Convert power ↔ current and plan conductor size. Planning estimates only — use a licensed electrician for installation.
Suggested path: Watts↔amps → Wire size → AC↔DC
Watts to Amps
Convert power to current for DC, single-phase AC and three-phase circuits.
Open toolAmps to Watts
Convert current to watts for load planning and appliance checks.
Open toolWire Size Calculator
Voltage-drop limited mm² / AWG estimate for copper or aluminum runs.
Open toolAC ↔ DC Calculator
Account for efficiency and power-factor losses in conversion.
Open toolHonest positioning
- MEPCODBill is a privately run educational site. It is not the official MEPCO website and does not fetch live official bill data into these calculators.
- Tariff figures on tool pages are planning assumptions. Always verify against your printed bill and NEPRA tariff schedules. Estimates differ due to FPA, QTA, arrears, ToU splits and fixed charges.
- Electrical sizing tools are planning estimates only — have a licensed electrician confirm installation and local code compliance.
- Need the official invoice? Use our reference-number lookup, which forwards you to the PITC portal.
Experience
Built around the real consumer path: reference number → PITC portal, plus planning calculators you can run before the paper bill arrives.
Expertise
Guides explain FPA, QTA, GST, ToU and metering in plain language, with formulas documented on each tool page.
Authoritativeness
We cite NEPRA schedules and the PITC bill portal — and we never pretend to be MEPCO.
Trust
No fake bill PDFs, no fabricated live fetch, clear ads/cookie disclosure, and a published corrections path.
