Free parking calculators

An aboveground structured parking space cost about $52,000 to build in early 2026, before land. Underground ran about $73,000 (UCLA Institute of Transportation Studies, February 2026). Owners commit to numbers that size on defaults more often than anyone admits: a code ratio, an old rate card, a curb allocation nobody has measured. These calculators are the first check. How many spaces a project actually needs. Whether an accessible count holds up. What a block of curb produces. Where rates should sit against demand. Each one runs in the browser, free, no signup. Enter what you know and walk away with a number worth taking into the room.

01

Shared parking calculator

How many spaces a mixed use project actually needs when its uses peak at different hours. Offices fill by day, homes by night, restaurants in the evening, and the same stall can serve all three. The calculator estimates the combined peak instead of stacking every use's maximum, which is how projects end up overbuilt.

A planning-level estimate, not engineering advice or a zoning determination.

02

ADA space count checker

How many accessible spaces a lot or garage needs at its size, and how many of those must be van accessible, following the count table in the 2010 ADA Standards for Accessible Design. Medical facilities carry higher ratios for patient and visitor parking, and each separate lot is counted on its own.

7accessible spaces required
Van accessible (included)2
Standard accessible5

A planning-level check, not a legal compliance determination; dimensions, aisles, slopes, and signage still need field verification.

03

Curb productivity calculator

What a stretch of curb produces under a given use. Parked cars, loading zones, and passenger pickup serve very different volumes, and few blocks have ever had the difference put into numbers. The calculator estimates vehicles served and revenue per curb foot per hour, so allocations can be compared on output instead of habit.

2.7vehicles served per hour
Vehicle positions on curb4
Revenue per hour$16
Revenue per curb foot per hour$0.16

A planning-level estimate, not engineering advice or a traffic study.

04

Rate setting worksheet

Where posted rates sit against demand. A facility that fills early at the posted rate is leaving money on the table; one that sits empty may be priced past its market. The worksheet reads each facility against a target occupancy and estimates what a measured adjustment could mean for annual revenue.

$24.88suggested rate per hour
Current estimated annual revenue$15,552,000
Projected at target occupancy$19,029,375
Estimated annual change$3,477,375

Fills past target: room to raise the rate.

A planning-level estimate, not pricing advice; demand response varies by market and should be measured after any change.

The full model

When one number is not enough

The calculators answer one question at a time. The JDE parking pro forma workbook puts the whole operation in one model: revenue build up by product, operating expenses, capital items, and sensitivity to rate and occupancy moves. We trade it for a work email, and we do not add you to anything without asking.

When the estimate raises a question

That is the point of running it. These tools are planning-level on purpose; the decisions they feed are not. If the shared parking number says the project is overbuilt, if the accessible count comes up short, if the rate worksheet shows money on the table, the next step is a conversation. Bring the estimate. We will tell you whether it holds.
