Fleet V2G Revenue Estimator
Net V2G value per year: export revenue minus buy-back energy and battery-wear cost.
Aggregated fleets (100+ kWh per vehicle-night) are what grid operators actually contract. Estimate per-vehicle annual V2G value net of round-trip losses and battery wear, then scale by your fleet count.
V2G pays only when the price spread beats round-trip losses plus battery wear. LFP packs (4,000+ cycles) wear ~half as fast per kWh as NMC — chemistry decides whether the same spread is profit or loss.
Indicative estimates only, not financial or investment advice. Tariffs, subsidies and net-metering rules change — verify with your DISCOM, utility or installer before committing.

Frequently asked questions
Is vehicle-to-grid actually profitable?+
Only when the price spread beats round-trip losses plus battery wear. With an LFP pack, 88% RTE and a ₹5+/kWh spread, modest daily exports net a real profit; with NMC wear costs and thin spreads, V2G loses money politely. This calculator's three-line accounting shows your case.
How much does V2G wear out the battery?+
Each exported kWh adds throughput: cost ≈ pack value ÷ lifetime throughput. For a ₹12k/kWh LFP pack rated 4,000 cycles, wear runs ~₹0.7–1/kWh exported; NMC roughly doubles that. Wear cost is the gatekeeper — chemistry decides whether the same spread is profit or loss.
What's the difference between V2G and V2H?+
V2G sells into the grid/market and needs utility programs plus a bidirectional charger; V2H powers your own home during peaks or outages — no program needed, and the 'sell rate' is your retail tariff or the diesel-genset cost you avoid. V2H usually pencils first.
Does V2G void EV battery warranties?+
Historically many OEMs excluded it; that's shifting — several now warrant approved bidirectional use. Check your warranty's language on 'external discharge' before enrolling, and keep exports within any stated envelope. The wear math here helps you decide if it's worth even asking.
