V2G (Vehicle-to-Grid) Revenue Calculator

V2G (Vehicle-to-Grid) technology lets electric vehicle owners sell stored battery energy back to the power grid — turning a parked car into a revenue source. Enter your battery capacity, discharge power, session duration, energy prices, and cost inputs into the V2G Revenue Calculator to find your Annual Net Revenue. Secondary outputs include monthly energy and capacity revenue, annual battery wear cost, hardware payback period, and monthly energy throughput. Also try the calculate Total Annual Savings, Annual Fuel Savings & Annual Maintenance Savings — EV Maintenance Savings.

What is Vehicle-to-Grid (V2G) technology?

V2G technology allows electric vehicles to discharge stored energy back to the electrical grid. This bidirectional charging capability turns EVs into mobile energy storage units that can provide grid services and generate revenue for owners. See also our EV Break-Even Calculator.

Do I need a specific EV for V2G?

Yes, V2G requires vehicles with bidirectional charging capability and compatible charging equipment. Currently, only certain EV models support V2G, including some Nissan Leaf variants, Mitsubishi Outlander PHEV, and newer Ford F-150 Lightning models.

How accurate is the battery wear estimate?

The calculator uses industry-standard cycle life data, but actual battery degradation varies based on temperature, charging patterns, and battery chemistry. Modern EV batteries are designed to handle thousands of cycles with minimal degradation.

What is the capacity premium and how do I enter it?

The capacity premium is payment for making your EV's power capacity available to the grid, even when not actively discharging. This varies by utility and market, typically ranging from $10-50 per kW per month. Check with your local utility or V2G service provider for current rates. You might also find our EV Fleet Savings Calculator useful.

What factors most impact V2G profitability?

The biggest profit drivers are the price spread between buying and selling electricity, capacity premium payments, and frequency of participation. High-value grid services during peak demand periods offer the greatest revenue potential.

Does V2G affect my car's battery life?

V2G does add charge-discharge cycles to your battery, but modern EV batteries are designed for thousands of cycles. The calculator factors in battery wear costs, and many V2G programs include battery warranties or degradation protection.

Can I use both V2G and V2H with the same vehicle?

Yes, many systems support both Vehicle-to-Grid and Vehicle-to-Home functionality. You can prioritize home backup power during outages while participating in grid services during normal operation, though not simultaneously.

When does V2G make financial sense?

V2G is most profitable with high electricity price spreads, frequent grid service opportunities, and vehicles that are parked and plugged in regularly. Areas with time-of-use rates and grid instability offer the best revenue potential.
