How does the EV Range Calculator work?
Our Electric Vehicle Range Calculator factors in your battery capacity, current charge level, driving mode, terrain, payload, temperature, and climate control usage to estimate your EV's real-world driving range. It provides instant calculations based on your specific driving conditions.
What factors affect EV range the most?
Your current battery charge level, temperature (especially cold weather), driving speed, terrain elevation, payload weight, and climate control usage are the biggest factors affecting real-world EV range. Our calculator accounts for all these variables.
How accurate is the EV Range Calculator?
The calculator provides realistic estimates based on real-world factors including your current battery charge level. While manufacturer ratings are tested under ideal conditions, our tool accounts for your actual charge percentage, temperature, terrain, payload, and driving style that affect actual range.

What is the Electricity Bill Calculator India?
Our Electricity Bill Calculator India is a free online tool that helps you calculate your electricity bill from meter readings. Simply enter your connected load, previous and current meter readings (or units consumed directly), rate per unit, fixed charges (optional), and any applicable subsidies to get an accurate bill breakdown with energy charges, fixed charges, and total bill amount.
How do I calculate electricity bill from meter reading in India using this tool?
To calculate your electricity bill from meter reading:
1. Enter your connected load in kW
2. Input your previous and current meter readings (in kWh), or enter units consumed directly
3. Enter your electricity rate per unit (₹/kWh) - this varies by state and consumption slab
4. Optionally enter fixed charges (or leave blank to auto-calculate at ₹50/kW)
5. Add any applicable subsidies if applicable
6. Click 'Calculate Bill' to see a detailed breakdown
The tool automatically calculates units consumed from meter readings and provides a complete bill breakdown with energy charges, fixed charges, and total amount.
How accurate is the Electricity Bill Calculator?
Our calculator provides accurate estimates based on standard electricity billing formulas used in India. However, actual bills may include additional charges like fuel adjustment charges (FAC), electricity duty/tax, meter rent, and slab-based tiered rates. For the most accurate calculation, use the exact rates from your electricity bill. The calculator is best used for estimation and understanding bill components.
What is the difference between connected load and units consumed?
Connected Load (kW) is the total capacity of all electrical appliances you have connected, regardless of whether they're running. It determines your fixed charges (typically ₹50-100 per kW per month). Units Consumed (kWh) is your actual electricity consumption measured by the meter - calculated as the difference between current and previous readings. This determines your energy charges. For example, if you have 5 kW connected load, you pay fixed charges for 5 kW even if you only use 2 kW at any given time.
Can I use the Electricity Bill Calculator for commercial or industrial connections?
Yes, the calculator works for all consumer categories (domestic, commercial, industrial). However, you'll need to use the appropriate rates for your category, as commercial and industrial rates are typically higher than domestic rates. Also, fixed charges may be calculated differently for commercial/industrial connections. Always refer to your electricity provider's tariff schedule for category-specific rates.
