About this tool
Estimate electricity use and a simple bill from appliance power, operating time and the tariff assumptions entered. Compare energy use with fixed charges rather than treating every device’s rated power as a monthly expense.

- Work with Total Appliance Load / Power (Watts); Average Usage per Day (Hours); Billing Cycle Days.
- Review Daily Consumption; 30-Day Total Units; Energy Charge in the result breakdown.
Benefits
- Turn operating hours into an energy estimate.
- Compare appliance-use scenarios on a consistent tariff basis.
Who should use this tool?
- Households reviewing an energy budget.
- People comparing appliance-use assumptions.
How to use
- Complete the labelled fields for your scenario, including Total Appliance Load / Power (Watts); Average Usage per Day (Hours); Billing Cycle Days. Use the units shown beside each field.
- Try the example labelled “1.5 Ton AC (1500W) Running 8 Hrs/Day for 30 Days @ ₹7.5/Unit” if you want to check the workflow first.
- Select Calculate / Run Tool and review Monthly Electricity Units & Estimated Bill and Daily Consumption; 30-Day Total Units.
- Check the assumptions and limitations below. Adjust a value to compare scenarios, then copy or download the result you need.

FAQs
Will this match a utility’s exact bill?
Actual bills may use slab rates, taxes, fuel adjustments, minimum charges and meter readings. This estimate follows the tariff and charge assumptions represented in its fields.
Which inputs do I need for Electricity Bill & Appliance kWh Unit Consumption Calculator?
Use Total Appliance Load / Power (Watts); Average Usage per Day (Hours); Billing Cycle Days; Electricity Tariff per Unit (kWh) (₹), then complete the remaining fields for your scenario. The built-in examples show how those fields fit together.
What should I check before using this result?
Uses user-entered average per-unit tariff and fixed load charge. Check the assumptions and output against your intended task before relying on the result.
