AC Electricity Cost Calculator
Estimate AC electricity bill using capacity, star rating, and usage hours.
What is an AC Electricity Bill Calculator?
An AC Electricity Bill Calculator is an online tool that helps you estimate how much electricity your air conditioner consumes and how much it may cost you.
By inputting details such as AC capacity, star rating, type, technology, daily usage hours, and electricity rate, you can get a clear picture of your AC's energy consumption and associated costs.
This calculator works for both inverter ACs and non-inverter ACs and gives an approximate idea of your electricity expenses.
Inverter AC vs Non-Inverter AC Electricity Consumption
Inverter ACs are designed to be more energy-efficient compared to non-inverter ACs. They adjust their compressor speed based on the room temperature, leading to significant energy savings.
- Inverter AC adjusts compressor speed and consumes less electricity.
- Non-Inverter AC works on ON/OFF cycles and consumes more power.
On average, an inverter AC can save 20% to 30% electricity compared to a non-inverter AC. This calculator factors in these differences to provide accurate estimates based on the type of AC you use.
Example AC Electricity Cost Calculation
Let's say you have a 1.5 Ton, 3-Star Split Inverter AC that you use for 6 hours daily, and your electricity rate is ₹7 per unit.
Estimated Results:
- Effective Power Consumption: 1.22 kW
- Daily Electricity Units: 7.29 units
- Monthly Electricity Units: 218.70 units
- Estimated Daily AC Cost: ₹51.03
- Estimated Monthly AC Cost: ₹1,530.90
- Estimated Yearly AC Cost: ₹18,370.80
Note: These values are estimates. Actual consumption may vary depending on room size, temperature, and usage conditions.
Factors That Affect AC Electricity Consumption
The electricity consumption of your AC depends on several factors. Understanding these factors helps you manage your electricity usage and reduce your bills.
- AC Type and Technology: Window AC, Split AC, or Inverter AC. Inverter ACs consume less power than non-inverter ACs.
- Star Rating: Higher star-rated ACs are more energy-efficient.
- Cooling Capacity (Tonnage): Larger ACs (like 2 Ton) consume more electricity than smaller ones (like 1 Ton).
- Daily Usage Hours: Longer daily usage increases electricity consumption.
- Room Size and Insulation: Bigger rooms or poorly insulated rooms require more energy to cool.
- Temperature Setting: Lower thermostat settings (e.g., 18°C) increase power consumption.
Frequently Asked Questions (FAQs)
How many electricity units does an AC consume per day?
The number of units an AC consumes per day depends on AC capacity, star rating, usage hours, and whether it is inverter or non‑inverter. For example, a 1.5 Ton AC running 6–8 hours a day can use around 6 to 9 units per day.
What is the difference between inverter AC and non‑inverter AC electricity consumption?
Inverter ACs adjust compressor speed and are more efficient, often saving around 20%–30% electricity compared to non‑inverter ACs, which run at full power in ON/OFF cycles.
Can this AC Electricity Bill Calculator estimate monthly and yearly costs?
Yes, this calculator estimates daily, monthly, and yearly AC electricity costs based on your inputs like usage hours and electricity rate per unit.
Is the AC Electricity Bill Calculator accurate for my actual bill?
The calculator provides estimated values. Actual electricity bills may vary due to factors like room size, temperature settings, insulation, and real usage patterns.
Does AC star rating affect electricity consumption?
Yes, AC star ratings indicate energy efficiency. Higher star‑rated ACs (like 4★ or 5★) consume less electricity compared to lower star‑rated units.
What inputs do I need to calculate my AC electricity cost?
You need to enter AC capacity (Ton), star rating, AC type (split/window), inverter or non‑inverter technology, daily usage hours, and your electricity rate (₹/unit).
