Parking Revenue Per Stall Calculator

Parking can be a material component of urban commercial NOI — often 10-20% of total building value. This calculator separates monthly contract revenue from transient (hourly/daily) revenue and computes per-stall NOI and implied value at a parking cap rate.

How the math works

Parking NOI is often a material slice of urban CRE value — 10-20% of total building value in downtown Class A. This calculator computes per-stall revenue, NOI, and implied value at a parking cap rate (typically higher than office: 7-9%).

Parking operating ratios are high — valet, equipment maintenance, insurance. 30-40% OER is typical on mid-size structures. Surface lots can run as low as 15-20%.

Frequently Asked Questions

Parking cap rate vs building?

Parking is typically 100-200 bps above the office or retail cap rate — investors require higher yield because parking cash flow is more volatile (tech tenants go hybrid, transit expands). CBD garage cap rates typically 6.5-9%.

Valet vs self-park?

Valet increases utilization (tandem + stacking) and rate but adds 20-30% OER for labor. Self-park has lower OER but caps utilization. Busy downtown garages typically run valet during peak hours only.

Transient vs contract split?

Office-centric buildings: 70/30 contract/transient. Stadium/convention-adjacent: 30/70. Mixed-use towers: 50/50. Transient carries higher rate but volatile volume.
