Parking occupancy is the share of a lot's spaces that are in use. It shows whether a lot is underused, running comfortably, or so full that drivers struggle to find a space, and it is one of the most useful numbers for setting rates and judging a lot's income potential.
Use the calculator below to estimate average and peak occupancy from the number of spaces in use.
Key Takeaways
- Formula: Occupancy Rate = Occupied Spaces ÷ Total Spaces × 100.
- Average vs. peak: Average occupancy shows typical use; peak occupancy shows your busiest moment. Track both.
- Practical full point: Many parking planners treat roughly 85% occupancy as effectively full, since finding a space gets hard beyond it.
- Low occupancy: A wide gap between peak and average often points to pricing, permit, or marketing opportunities.
- Measure over time: Count at several times on weekdays and weekends for a reliable average.

What Is Parking Occupancy?
Parking occupancy, also called the occupancy rate or utilization rate, measures how much of a lot's capacity is in use. The basic calculation is:
Occupancy Rate = Occupied Spaces ÷ Total Spaces × 100
- Total Spaces: The number of usable spaces in the lot, excluding blocked or closed spaces.
- Average Spaces Occupied: The typical number of vehicles parked across your operating hours, based on several counts.
- Peak Spaces Occupied: The highest number of vehicles parked at one time.
- Unused Spaces: Total spaces minus occupied spaces, or the capacity you could still sell.
Worked Example
Say a lot has 100 spaces. Counts taken across several weekdays and weekends average 62 vehicles, and the busiest count is 88 vehicles.
Average: 62 ÷ 100 × 100 = 62%
Peak: 88 ÷ 100 × 100 = 88%
On average 38 spaces sit empty, and even at the busiest time 12 remain open. The lot reaches practical full only at peak, so there may be room to sell more monthly permits or fill quiet hours with discounted rates. Enter your own counts above to see your numbers.
What Is a Good Parking Occupancy Rate?
There is no single target for every lot. Parking planners often treat about 85% occupancy as the practical full point, because beyond it drivers spend more time searching for a space. An average well below that leaves capacity unsold, while a peak at or above it may mean you could raise rates or add spaces.
The right goal depends on your lot's location, mix of hourly and monthly parkers, and pricing.
How to Increase Parking Lot Occupancy
- Sell monthly permits: Reserved or permit parking fills spaces that stay empty during slow periods.
- Use time-based pricing: Lower rates at off-peak hours can attract drivers who would otherwise park elsewhere.
- Partner with nearby businesses: Offices, restaurants, venues, and hotels can send steady demand to your lot.
- Improve visibility: Clear signage, accurate online listings, and a listing on parking directories make the lot easier to find.
- Add event and overnight parking: Concerts, games, and overnight stays create demand outside normal hours.
- Review your pricing: If peak occupancy is near full, rates may be too low; if occupancy is low all day, they may be too high.
Frequently Asked Questions
How do you calculate parking occupancy?
Divide the number of occupied spaces by the total number of spaces, then multiply by 100. For example, 62 occupied spaces in a 100-space lot is 62% occupancy.
What is a good parking occupancy rate?
It depends on the lot, but many parking planners treat about 85% as the practical full point, because drivers start circling and searching once a lot climbs past it. Average occupancy well below that can mean unused revenue potential.
What is the difference between average and peak occupancy?
Average occupancy is the typical share of spaces in use across the operating period. Peak occupancy is the highest share in use at any one time. A lot can look underused on average and still fill up during busy hours.
How can I increase parking lot occupancy?
Lower prices at slow times, add monthly or permit parking, partner with nearby businesses, improve signage and online listings, and list the lot on parking directories so drivers can find it.
How do I measure how many spaces are actually used?
Count occupied spaces at set times, such as hourly on several weekdays and weekends, or use gate, camera, or sensor data. Enter the average and the busiest count into the calculator.
