About EVSolarCalculator.online
EVSolarCalculator.online is a free calculator hub built for Indian users who want clear, honest numbers for three big financial decisions: buying an electric vehicle, installing rooftop solar, and building a home.
Why We Built This
Most online calculators for India are either generic tools on installer websites (designed to capture leads, not give answers) or thin widgets with no context. We wanted calculators that show the actual math, cite the actual rules, and help you make a decision without a salesperson in the loop.
Every calculator on this site shows the computation behind the result. We don't just say "your subsidy is ₹78,000" — we show exactly how that number is derived, what assumptions went into it, and where the data comes from.
What We Offer
- 15 free calculators across EV, solar, and construction — no login, no signup, no lead capture
- 28 state-wise electricity rate pages for EV charging cost calculations
- 28 state-wise solar subsidy pages showing PM Surya Ghar central subsidy details
- 20 city-wise material price pages for construction cost planning
- All calculator inputs processed in your browser — your data never leaves your device
Our Data Sources
- PM Surya Ghar subsidy: pmsuryaghar.gov.in (official national solar subsidy portal)
