Free Online Parking Fee Calculator
Calculate parking charges from entry and exit times.
Charges are based on started hours: any part of an hour is billed as a full hour. A grace period waives the charge only when the total stay is within it; otherwise billing starts at entry.

About the Parking Fee Calculator
Parking charges are rarely a simple hourly multiplication. Garages apply grace periods, started-hour rounding, first-hour flat rates, evening rates and daily maximums, and the final bill can be hard to predict. This calculator takes entry and exit date-times, an hourly rate, a grace period and an optional daily cap, then shows the charge together with a line-by-line breakdown. It handles stays that cross midnight and uses the same started-hour logic that many paid parking facilities use.
Started-hour billing
Most facilities charge for every hour or part of an hour. A 61-minute stay is billed as two hours, not one. The calculator rounds the duration up to the next whole hour after confirming that the stay exceeds the grace period. If you enter 90 minutes, expect two billed hours. This is why a short appointment can cost more than the posted hourly rate suggests. Some garages use finer increments such as 15 or 30 minutes, so check the sign at the entrance if precision matters.
Grace periods and flat first hours
A grace period is a short free window, often 10 or 15 minutes, intended for drop-offs and quick errands. When the total stay is within the grace period, the charge is zero. When it is longer, billing generally starts from entry rather than after the grace minutes. A flat first-hour rate replaces the hourly charge for the first hour and then reverts to the hourly rate. That option is useful at airports and city garages where the first hour has a premium price. The breakdown shows which rule was applied.
Daily maximums and multi-day stays
A daily maximum caps the charge for each 24-hour period. A garage with a 3.50 hourly rate and a 24 daily maximum will not charge more than 24 for a full day, even though 24 hours at the hourly rate would be 84. The calculator splits a multi-day stay into full days plus a remaining part day, caps each period separately, and reports how much the cap saved. This matters for airport parking, hospital garages and long weekend stays where the cap can cut the bill dramatically.
What the estimate does not include
The tool does not know about lost-ticket fees, validation stamps, event pricing, surcharges for oversized vehicles, taxes, or rates that change by time of day. It also assumes the rate you enter is the rate that applies for the whole stay. Real garages may charge a different evening or weekend rate, or may round entry and exit times to the nearest few minutes. Use the breakdown to understand the structure, then confirm the final amount with the operator or the payment machine.
Frequently asked questions
Is the grace period deducted from the billable time?
No. This calculator uses the common rule that a grace period waives the charge only for stays within it. Once the stay is longer, billing starts at entry. If your garage deducts the grace minutes instead, subtract them from the duration before comparing the result.
How is an overnight stay handled?
Enter the full date and time for both entry and exit. The calculator uses the real elapsed time, so a stay from 22:00 to 06:00 is eight hours and is split across days only if it crosses a full 24-hour boundary.
Why is the total lower than hours multiplied by rate?
A daily maximum, a flat first hour, or both may be limiting the charge. The breakdown lists the cap saving and the first-hour rule so you can see exactly where the difference comes from.
