Frequently Asked Questions
Common questions about our calculator tools
Do I need an account to use the calculators?
No. All 12 calculators are completely free and require no signup or account. Just open any calculator, enter your AC details, and get instant results.
How accurate are the BEE 2026 ratings used in the calculators?
All calculators use the latest BEE 2026 ISEER star rating data, verified against official Bureau of Energy Efficiency notification schedules. Star ratings, wattage values, and efficiency curves are updated quarterly.
Which calculator should I use first?
Start with the AC Monthly Bill Calculator to estimate your running cost. Then use the AC Tonnage Calculator to verify you have the right capacity, and the Inverter Savings Calculator to see if upgrading from 3-star to 5-star is worth it.
Are city electricity rates pre-loaded?
Yes. All calculators include pre-loaded electricity tariff rates for all 23 major Indian cities and 18 states. You can also enter a custom rate if your local tariff differs.
Can I compare multiple AC models using these tools?
Yes. Use the AC Comparison Tool to side-by-side compare up to 4 models across price, wattage, ISEER rating, and annual running cost. The tool also generates a downloadable comparison PDF.
