EV Charging Membership Calculator

Enter your actual member and nonmember energy rates, eligible charging volume and billed months. See annual savings and the eligible kWh needed to break even.

Results

Net membership savings per year: 8.00 currency units
Without membership: 90.00 currency units
With selected billed months: 82.00 currency units
Break-even eligible kWh per active month: 46.667 kWh
Savings if billed all 12 months: -69.00 currency units

Negative savings means membership costs more. Ineligible sessions receive no discount. Taxes, idle fees and session fees are excluded; add only comparable all-in energy rates.
Assumes the member rate applies during every active charging month. Check cancellation and billing terms before choosing billed months.

How it works

The operator pricing page says prices depend on location and plan. Enter the rates for the stations and times you will use; no network price or percentage discount is built in.

Annual savings = active months × eligible kWh × (guest rate − member rate) − billed months × fee Break-even kWh per active month = billed months × fee ÷ [active months × rate difference]

Ineligible sessions cost the same under both choices. Equal or higher member rates have no volume-based break-even. A zero fee and equal rates produce a tie.

All prefilled prices, loads and performance assumptions are hypothetical examples. Use one currency throughout. Calculations keep full precision internally; displayed energy and money are rounded, and year-end payback is shown in whole years where applicable.

Worked examples

One road-trip month

With a fee of 7, rates of 0.60 and 0.45, 100 eligible kWh and 50 ineligible kWh at 0.60, no membership costs 90 and membership costs 82. Savings are 8; break-even is 46.667 eligible kWh.

Keeping membership all year

For the same single charging month but 12 billed months, membership costs 159. Annual savings are −69 and break-even is 560 eligible kWh in that month.

Frequently asked questions

Does the discount apply everywhere?

Use actual eligible stations and sessions. Station rates and time-of-use periods can differ; inspect the operator app or charger.

Can I enter a percentage discount?

Convert it to an actual member rate first. A 0.60 rate with a hypothetical 25% discount becomes 0.45.

Are idle fees included?

No. Add session-specific fees separately. This model compares energy rates and the membership fee.

What if I only need one month?

Set active and billed months to 1, if the plan terms allow it. The all-year comparison shows the cost of paying 12 fees.
