Parking Income Calculator
Parking is ancillary income most operators under-monetize. This calculator sizes monthly gross, NOI, and the valuation lift at your cap rate — including EV charger surcharges that are becoming standard on refreshed assets.

How the math works
Parking is the most under-valued income stream at most multi-family and mixed-use properties. Dense urban submarkets get $150–$400 per stall per month; suburban garden-style gets $50–$100. EV charging adds $25–$75 surcharge per stall and is increasingly table stakes for new construction.
Operators routinely leave 20%+ of potential parking income on the table with under-priced or unassigned stalls. Re-striping, assigning numbered stalls, and charging separately (instead of bundling in rent) typically lifts parking revenue 30–80% in the first year. Valued at the property cap rate, that revenue uplift can add meaningful equity.
How to Use
- Enter total parking stalls on the property.
- Enter monthly rent charged per stall.
- Set realistic occupancy (most garages run 80-90%).
- Enter EV charger surcharge and number of EV stalls if applicable.
- Enter annual maintenance per stall (striping, lighting, signage).
- Enter the cap rate the property values at for the valuation lift.
Frequently Asked Questions
What's a realistic monthly stall rate?
Dense urban: $150-$400/month. Suburban garden-style multifamily: $50-$100. Transit-adjacent mixed-use: $100-$250. Covered or garage stalls get a 25-50% premium over open-lot stalls.
Can I add parking revenue if rent already includes it?
Yes, though it's a negotiation at renewal. 'Unbundling' parking from rent is legal in most markets and often lifts NOI even if face rent drops. San Francisco, Portland, and Minneapolis encourage unbundling to support transit-oriented development.
How much do EV chargers cost to install?
Level 2 chargers are $2,000-$7,000 installed (equipment + electrical + striping). DC fast chargers $40,000+ and usually aren't practical at residential. Utility incentives and federal tax credits offset 30-50% in many states.
Do parking fees go in NOI?
Yes — parking revenue is operating income, and is included in NOI and therefore in cap-rate-based valuation. Capital spent on parking improvements (striping, signage, EV install) is capex, not OpEx.
