More electricity calculators

Each one answers a single question in a few seconds — from "how many units will ৳1,000 buy?" to whether rooftop solar pays back.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

These are concrete, locally-tested ways to reduce your monthly bill — ordered by how much each typically saves.

• Set your AC to 24–26°C, not 18°C

  ~৳400–৳1,200 / month for a 1.5-ton AC

  Every degree below 24°C increases AC consumption by roughly 6–8%. Most rooms in Bangladesh cool comfortably at 25°C with a ceiling fan on low. Combined with closed curtains during peak sun hours, this single change can shave 15–25% off a summer bill.

• Keep your fridge at 3–5°C and the freezer at −18°C

  ~5–10% on total household consumption

  Refrigerators are the single largest always-on appliance in most homes. Setting the fridge colder than 3°C or the freezer below −18°C makes the compressor run continuously without preserving food any better. Clean the back coils once a year and leave 5cm of breathing space behind the unit.

• Replace every CFL and incandescent bulb with LED

  ~৳50–৳150 / month per bulb replaced

  A 9W LED produces the same brightness as a 60W incandescent and lasts 15× longer. Bangladesh-imported LED bulbs cost ৳150–৳300 and pay for themselves in 4–6 months on a normal usage pattern. Prefer 4000K (neutral white) for living areas and 3000K (warm) for bedrooms.

• Unplug chargers, set-top boxes and old TVs when not in use

  ~৳100–৳300 / month

  Phantom load — devices drawing power while "off" — typically accounts for 5–10% of a residential bill in Bangladesh. The worst offenders are CRT-era TVs, satellite receivers left in standby, and old desktop computers. A simple multi-plug with a master switch fixes this in seconds.

  Why bills run high →

• Shift heavy appliances to off-peak hours if you are on a TOU meter

  30–40% on shifted units

  If your meter supports Time-of-Use tariff, running the washing machine, iron, or water pump after 11 PM (off-peak) instead of 5–11 PM (peak) can cut those units' cost by 30–40%. Check your bill — the peak/off-peak label is printed on every TOU statement.

• Lower geyser temperature and switch off when not needed

  ~৳600–৳1,500 / month

  Most electric water heaters are factory-set to 70°C — far hotter than anyone bathes. Drop the thermostat to 55°C and switch the heater off at the wall when you leave for work. A 2000W geyser left on all day silently adds 200+ units a month.

• Small household? Mind the 50-unit lifeline line

  ~৳39 for a single unit at the 50 → 51 line

  Slabs only reprice the units inside each step — going from 300 to 305 units adds 5 units at the next rate, not a higher rate on all 305. The one real cliff is the lifeline: at 50 units or less every unit costs ৳4.63, but at 51 the whole month moves to the stepped rates. If you usually land just above 50, trimming a few units in the last week of the billing cycle pays off.
