How the math works
Annual revenue = stations × (premium + usage) × 12. Net = revenue − maintenance. Payback = install / net.
12 stations × $5,500 = $66k install. Net $13.7k/yr. Payback 4.8 years. Quicker with rebates (often 25-40% offset). Tenant attraction/retention benefit: additional soft payback.
How to Use

- Enter install cost per station.
- Enter monthly premium rent per station.
- Enter monthly revenue per station.
- Enter maintenance per station.
