Most commercial EV charging ROI models are either too optimistic (inflated utilization assumptions, missing operating costs) or too pessimistic (ignoring incentives and indirect value). Building a model that's actually useful requires separating what you can measure from what you're estimating.
This article covers Level 2 commercial charging, which is the right model for multifamily, workplace, hotel, retail destination, and similar dwell-time use cases. DC fast charging behaves differently on almost every line of the model (demand charges, install per port, utilization baselines, NEVI dependency); for that case, see DC Fast Charging ROI: Why the Math Is Different.
The ROI framework: two buckets
⚠️ Time-sensitive: The Section 30C Alternative Fuel Vehicle Refueling Property Credit expires June 30, 2026. Equipment must be physically placed in service by that date (not ordered, not permitted, not under construction). No extension legislation has been introduced. After June 30, there is no federal EV charger tax credit.
All commercial EV charging returns fall into one of two categories: direct cash flows on the bank statement, and indirect value that has to be deliberately counted.
A common mistake: presenting the direct ROI as the complete picture. For many property types (especially multifamily and office), the indirect returns are larger than direct charging revenue, but they require a deliberate decision to count them, not an assumption they'll materialize.
Three worked examples
Example 1: 20-unit multifamily in a medium-adoption market
Assumptions:
- 20 apartments, 10% current EV ownership = 2 EV-owning residents
- Market EV adoption at 8%, growing to 18% in 3 years
- Installation: 4 Level 2 ports (40A), make-ready wired for 8
- Gross installation cost: $35,000 (4 chargers + infrastructure for 8)
- Utility make-ready program covers infrastructure: $18,000
- Net capital investment: $17,000
- 30C tax credit (30% of net): $5,100 credit
- Effective net investment: $11,900
Revenue model (Year 1):
- 4 chargers at 35% utilization (building demand + visitors)
- 6 kWh average per session
- 2 sessions/charger/day = 4 chargers × 2 × 6 kWh = 48 kWh/day
- Pricing at $0.25/kWh (as of Q1 2026) = $12/day gross
- Less electricity at $0.13/kWh (as of Q1 2026) = $6.24/day net
- Annual gross net revenue: ~$2,100
Operating costs (annual):
- Platform/network fees: $800 (4 ports × $200/port, as of Q1 2026)
- Maintenance reserve: $350 (2% of $17,500 hardware)
- Total operating cost: $1,150
Net annual direct contribution: $2,100 – $1,150 = $950
Payback on direct revenue alone: $11,900 ÷ $950 = 12.5 years, too long.
Including indirect value:
- Tenant retention: 2 current EV-owning residents renew instead of churning. Average turnover cost (vacancy + re-leasing): $2,500/unit (conservative/low-end estimate; typical range is $3,000–$6,000 depending on market). Value: $5,000/year retained
- As EV ownership grows to 4–6 residents by Year 3, retention value grows proportionally
Adjusted Year 1 total return: $950 + $5,000 = $5,950
Payback including retention: $11,900 ÷ $5,950 = 2.0 years
Year 2 and 3 direct revenue grows as utilization increases with more EV residents. The indirect value case, not the charging revenue, is what makes this investment work in Year 1.
California note: The $0.13/kWh electricity assumption reflects a national average for commercial rates. California property owners should use their actual rate schedule: SDG&E commercial TOU rates for EV charging run significantly higher, and PG&E TOU-EV tariffs have time-of-use structures that can substantially affect the per-session electricity cost. In high-rate California markets, re-run this example with your actual utility rate before drawing conclusions about payback. Your state page on this site lists the named PG&E, SCE, SDG&E, and LADWP residential and commercial EV programs in each service territory.
Example 2: 100-employee office, employee benefit model
Assumptions:
- 100 employees, 20% own EVs = 20 EV-driving employees
- Employer provides free charging as a benefit
- Installation: 12 Level 2 ports (40A), standard installation
- Gross installation: $85,000 (12 chargers + electrical)
- Utility make-ready program: $40,000 covered
- 30C credit (30% of $45,000 net): $13,500
- Effective net investment: $31,500
Revenue model: None; employer-subsidized, free to employees.
Operating costs (annual):
- Electricity: 20 employees × 50 kWh/week × 50 weeks × $0.12/kWh = $6,000
- Platform fees: $2,400 (12 ports × $200)
- Maintenance reserve: $875 (2% of $43,750 hardware)
- Total annual operating cost: $9,275
Indirect value: employee retention
- Annual cost of replacing one mid-level employee (recruiting, onboarding, productivity loss): $15,000–$25,000 (SHRM employee replacement cost benchmark)
- If EV charging benefit retains even 1 EV-driving employee who would otherwise leave: $15,000 value
- For tech and professional firms competing for talent, this is conservative; the benefit affects hiring decisions, not just retention
Net annual position: –$9,275 operating + $15,000 retention value = +$5,725
Payback: $31,500 ÷ $5,725 = 5.5 years
The entire case rests on the benefit value, not charging revenue. For a 100-person tech company spending $15M/year on compensation, the $9,275 annual operating cost for EV charging is rounding error in the benefits budget, with measurable retention upside.
Example 3: Highway-adjacent hotel, 8 Level 2 ports
Assumptions:
- 80-room hotel on I-95 corridor
- 8 Level 2 ports (48A), guest parking area
- Gross installation: $52,000 (8 chargers + electrical)
- No make-ready program in this state
- 30C credit (30%): $15,600
- Net capital investment: $36,400
Revenue model (charging sessions):
- 8 ports at 55% utilization
- 3 sessions/port/day × 12 kWh average = 36 kWh/port/day
- 8 ports × 36 kWh = 288 kWh/day
- Pricing: $0.30/kWh gross
- Revenue: $86.40/day, $31,536/year
- Less electricity at $0.14/kWh: $14,700/year
- Gross net: $16,836/year
Operating costs (annual):
- Platform/network fees: $1,600 (8 ports × $200)
- Maintenance: $650 (2% of $32,500 hardware)
- Total: $2,250
Net direct annual contribution: $16,836 – $2,250 = $14,586
Payback on direct revenue: $36,400 ÷ $14,586 = 2.5 years, strong.
Plus indirect value:
- Hotel appears in EV trip-planning apps (PlugShare, ABRP), which generates awareness-level traffic
- Higher guest satisfaction scores among EV drivers → better reviews, more bookings
- Some guests add a night specifically to fully charge before continuing → incremental room revenue
At 2.5-year direct payback plus indirect upside, this is among the strongest commercial EV ROI profiles. The highway corridor location is key; this only works for hotels with road-trip-relevant positioning.
Sensitivity analysis: what changes the payback
Utilization is the variable that matters most in the direct revenue model. Running three scenarios lets you see the real risk range.
Example: 10-port Level 2 installation, $90,000 net capital, $0.25/kWh pricing (as of Q1 2026), $0.13/kWh electricity cost (as of Q1 2026)
At 20% utilization, the direct revenue case doesn't work, which is why it's critical to include indirect value in the model. At 40% utilization and above, the direct case works on its own.
Most new installations sit at 20–30% utilization in Year 1 as local EV ownership builds. Year 3 targets of 50–65% are achievable for well-positioned properties in high-adoption markets.
Sensitivity to electricity rate: Every $0.01/kWh increase in electricity cost reduces annual net contribution by approximately $225/port/year at 40% utilization. If your utility is raising rates, build escalation into your model.
Sensitivity to incentives: If the 30C credit or a state grant disappears before your project closes, your net capital rises by the incentive amount. Model the "no incentives" case as your worst-case payback to confirm the project still makes sense without them.
Common model errors
Optimistic utilization in Year 1. New installations regularly sit at 10–20% utilization for 6–18 months while local EV ownership builds. Model Year 1 conservatively (20–30%), Year 3 at target utilization (50–70% for high-demand sites).
Ignoring demand charges. Commercial electricity customers pay demand charges (monthly fee based on peak kW draw). A cluster of chargers starting simultaneously can spike demand substantially. Load management software mitigates this, but quantify the exposure before finalizing the model.
Omitting platform fees. Network platform fees of $150–$300/port/year are real operating costs. They don't show up in equipment quotes; they show up in year 2 when you get the invoice.
Treating incentives as guaranteed. Verify that incentive programs are currently funded and accepting applications before building your model around them. Programs that existed last year may be exhausted this year. The 30C tax credit in particular expires June 30, 2026 under current law, with no extension legislation introduced. Do not model 30C as available for equipment placed in service after that date.
Not crediting indirect value. The direct revenue model alone understates true economic return for multifamily, office, and hospitality properties where retention and competitive positioning are significant. If your direct model doesn't work, ask whether indirect value changes the answer before concluding the investment is wrong.
The model structure you should use
Build your model with these rows:
Capital:
- Gross project cost (hardware + installation)
- Less: utility make-ready / grants (verify currency on your state page, which lists current residential and commercial incentives by state; see Utility EV Charger Rebates: A Growing Incentive Layer for the broader utility-side pattern)
- Less: 30C tax credit (expires June 30, 2026 under current law; confirm availability before projecting)
- = Net capital investment
Annual revenue: Sessions × kWh × price per kWh (or per-minute equivalent)
Annual costs: Electricity + platform fees + maintenance reserve
Net direct contribution: Revenue minus costs
Indirect value: Retention + competitive positioning (explicit assumption, not residual)
Total annual return: Direct + indirect
Payback: Net capital ÷ total annual return
NPV (optional): For multi-year analysis, discount at your hurdle rate
Run three utilization scenarios: 20% (conservative), 40% (moderate), 65% (mature). The investment should pay back on the moderate case, not just the optimistic one.
A note on timing: when to model vs. when to decide
The model is a decision tool, not a precision instrument. Real-world outcomes will differ from any projection. The value of the model is forcing explicit assumptions, particularly on utilization and indirect value, so you're making a deliberate bet rather than acting on optimism.
A project with a 7-year direct payback and meaningful tenant retention value is almost certainly worth doing for a multifamily owner with a 20-year hold period. A project with an 18-year direct payback and no credible indirect value story is almost certainly not. Most projects fall clearly on one side of that line once the model is built honestly.
Build the model before signing contracts, not after. If the numbers don't work at moderate utilization, no amount of contractor negotiation fixes the fundamental economics.
