Appliance-by-appliance bill breakdown
Calculate consumption to allocate the estimated monthly bill across your appliances.

Rows allocate the rounded household bill in proportion to modeled kWh, so they add back to the displayed total. This is a nameplate estimate, not a meter reading.

Appliance Power Usage in Africa — Know Your Consumers
Air conditioners, electric geysers, and old refrigerators are typically the top three electricity consumers in an African home — often accounting for 70%+ of your bill. This calculator breaks down usage appliance-by-appliance so you know exactly where your money goes.
Disclaimer: Wattage figures are typical values. Check your appliance's nameplate for exact rated power.
Build an appliance bill breakdown you can verify
The main calculator now ranks every entered appliance and allocates the displayed household bill by modeled monthly kWh. The rows add back to the calculator's rounded monthly total.
- Start with labels: enter rated watts, quantity, active hours, and any known standby watts.
- Read cost as an allocation: cycling appliances may use less than nameplate power, so a row is a planning estimate rather than a utility charge.
- Verify the largest row first: use a suitable plug-in meter, submeter, or a timed meter-reading test before buying replacement equipment.
Private by default. Appliance entries and the bill breakdown stay in this browser unless you choose to copy the result.
Frequently Asked Questions
How are the per-appliance monthly costs calculated?
The calculator allocates its rounded household bill across appliances in proportion to each appliance's modeled monthly kWh. This keeps the appliance rows aligned with the displayed total bill.
Does the wattage field show actual appliance consumption?
Not necessarily. Nameplate wattage is a planning input; compressors, thermostats, voltage, age, and duty cycles change real consumption. Use a suitable plug-in meter or submeter where practical.
How does the calculator treat standby power?
Appliance rows apply standby watts during the hours remaining after active use. The separate standby-cost metric assumes 24 standby hours per day as a conservative upper bound; measure standby draw where practical.
Confirm appliance usage before sizing power systems
Break down appliance watts, hours, standby load, kWh, and cost so generator, inverter, and solar decisions start from real usage.
Local-first estimate. No live quote or official approval is performed.
What to check
- Methodology: multiply appliance watts by quantity, hours, days, and tariff to estimate daily, monthly, and annual energy use.
- Verify appliance nameplate ratings, duty cycles, standby draw, actual usage hours, voltage stability, and current tariff class.
- Use the output to identify high-consumption appliances before changing equipment or sizing backup power.
Limitations
- Disclaimer: planning estimate only, not a utility bill, metered audit, appliance certification, or installer quote.
- Real consumption varies by age, compressor cycles, thermostat settings, ambient heat, voltage, and user behavior.
- Source/reference note: verify against appliance labels, smart-plug readings, utility tariffs, and energy-efficiency references.
Privacy note: the calculator runs in your browser. Do not paste account numbers, installer contracts, or private customer data into notes you plan to share.
