E-Rickshaw vs CNG Auto Calculator
Per-km running cost head-to-head and EV premium payback for cargo 3-wheeler fleet duty in India.
CNG autos at ~₹85/kg and 25 km/kg cost ~₹3.4/km in fuel; cargo e-3Ws run under ₹0.75/km. Enter CNG price as 'fuel price' and km/kg as economy — the payback row answers the fleet conversion question.
Energy/km = Wh/km × tariff; fuel/km = price ÷ km/L. Off-peak depot charging is what makes the EV column unbeatable — the same fleet charged at peak rates can double its energy cost/km.

Frequently asked questions
How do I compare EV running cost against diesel fairly?+
Per km: EV = Wh/km × tariff ÷ 1000; ICE = fuel price ÷ km/L. Use your real charging tariff (off-peak if that's your practice) and real route economy, not brochure figures. The calculator pairs the two and pays back the EV's price premium with the difference.
What's a typical payback for the EV price premium?+
High-utilization fleets (taxis, 3W cargo, delivery at 150+ km/day) commonly pay back in 1.5–3 years; modest-duty corporate cars take 4–7. Distance is destiny — payback scales inversely with daily km, which the tool makes explicit.
Are EV maintenance savings real?+
Consistently: no oil changes, no clutch, regenerative braking halving brake wear — fleet studies cluster around 35–45% lower maintenance per km. The calculator adds a conservative estimate; battery replacement risk is covered separately by warranty (see the battery warranty tools).
Does the E-Rickshaw vs CNG Auto Calculator include battery replacement cost?+
No — within typical fleet holding periods (4–7 years), packs stay under OEM warranty (8 yr/160k km to 70%). For longer horizons, add a residual provision using the battery replacement-planner tool; falling pack prices keep shrinking that line.
