Electricity calculators for Bangladesh
Free, tariff-aware calculators for everyday electricity questions in Bangladesh — what an appliance costs to run, whether solar pays back, how to convert watts to units, and what load shedding really costs.
Monthly bill calculator
The flagship calculator on the home page. Enter your meter category and units to get a full bill breakdown.
Compare electricity worldwide
What would the same electricity use cost elsewhere? Enter your monthly kWh and compare household benchmarks across 12 countries, with Bangladesh selected to get you started.
Appliance cost calculator
Enter wattage and daily run-hours for any appliance to see exact cost per day and per month at the current Bangladesh tariff. Covers single appliances and full-home loads.
Solar savings calculator
Estimate how much you save per month with a rooftop solar installation under the net-metering policy, including payback period and 25-year return.
Watt → unit converter
Quickly convert watts × hours of use into electricity units (kWh) per day or month, then into Taka at the rate that applies to your meter.
kWh ↔ unit
1 unit = 1 kWh = 1,000 watt-hours. They are the same quantity under two names, so there is nothing to convert — here is the arithmetic, what it costs in taka, and why watts are a different measure entirely.
Load shedding cost
Compare what an hour of load shedding actually costs when you switch to a diesel or petrol generator, versus what the same units would have cost on the grid.
Prepaid vs postpaid savings
Enter your monthly energy charge to see what the prepaid rebate actually saves you over a year and a decade, and weigh the indirect pros and cons against a postpaid meter.
Bill → units (reverse)
Know the amount but not the units? Enter what you were charged — a single figure, or the peak and off-peak split — pick your meter category, and see how many units that buys and the real price per unit.
New connection cost
Pick your category, phase and sanctioned load to get an itemised estimate of what a new connection costs upfront — deposit, application fee and meter charge — plus the recurring meter rent.
Prepaid recharge calculator
Enter what you recharge and your load to see how much reaches the meter as energy, and why the first recharge of the month always buys less.
Why a separate calculator for each problem?
The Bangladesh electricity tariff is not a single number. It has slabs that change with monthly units, demand charges that scale with sanctioned load, separate schedules for residential, commercial, agricultural and industrial use, and a 5% VAT applied on top of everything. A single “bill calculator” can answer the question “what will my next bill be?” but it cannot easily answer questions like “does running my AC for two extra hours actually move my bill?” or “if I install 5 kW of rooftop solar, how many years until I break even?”
Each calculator focuses on a specific question. Bangladesh tools use our shared tariff data. The worldwide comparison uses separately sourced household benchmarks, with their dates and coverage shown on the page.
How accurate are these numbers?
Bangladesh tariff rates come from the BERC tariff order; international benchmarks link to their own official sources. Check each calculator's assumptions and data period. Outputs are for planning and comparison; your distributor's issued bill is the official figure.
