Where do these rates come from?

They are representative median garage rates for each Seattle neighborhood, not a live feed. Downtown and South Lake Union are the priciest; the U-District and outer areas are cheaper. Treat them as planning estimates and confirm with your specific garage.

Why is monthly parking cheaper per day than daily parking?

Monthly passes bundle a fixed price regardless of how often you park, so committed commuters get a lower effective daily rate. If you park most weekdays, a monthly pass usually beats paying daily.

What is the event-rate multiplier?

Near stadiums and venues, garages raise prices on game and concert days — often 1.5x to 3x normal. Toggle the multiplier and set how many event days you expect to see the impact on your monthly cost.

Does this include street parking?

It models paid garage and lot rates. Seattle metered street parking is priced separately by zone and time of day, and is capped at a few hours, so it is not a substitute for all-day parking. Use the hourly mode as a rough proxy.

Seattle Parking Cost Estimator

Parking is one of Seattle’s quietest big expenses — a downtown monthly space can run around $225–$400, and hourly rates in the densest neighborhoods add up fast. This free estimator gives representative rates for major Seattle districts and projects your real monthly and annual parking spend, including an event-day surcharge near venues.

How it works

You pick a neighborhood, which loads representative hourly, daily, and monthly rates. The estimator then computes monthly cost based on how you park:

hourly:  monthly = hours/month * hourlyRate
daily:   monthly = days/month  * dailyRate
monthly: monthly = monthlyRate (flat)

If you enable the event multiplier, a share of your parking days are charged at the higher event rate:

eventExtra = eventDays * dailyRate * (multiplier - 1)

Annual cost is simply the monthly figure times twelve.

Notes and example

Parking daily in Downtown at a $32 daily rate, 20 days a month, comes to $640/month — about $7,680 a year, and that is before event surcharges. A monthly pass at $300 would save roughly $340 a month. The rates here are planning medians, not a live quote; confirm with your specific garage. Everything runs locally; nothing is uploaded.
