Estimate garage parking costs.
Garages bill by started hour and then cap the day, so the charge is the lesser of hourly accumulation and the daily maximum. That structure creates a plateau: once you cross the cap threshold — here around five to six hours at typical rates — extra hours are free, which is why a long stay can cost the same as a medium one. The effective hourly figure divides the actual charge by the actual hours and shows how quickly the cost per hour falls once the cap binds.
Per visit
Per visit = min(ceiling(hours) x hourly rate, daily maximum)
Monthly
Monthly = cost per visit x visits per month
Because part hours round up. Five hours and ten minutes bills as six, so leaving a few minutes earlier can genuinely save an hour's charge.
Usually, often 20 to 40 percent below the drive-up rate, because garages price surplus capacity in advance. The trade-off is a fixed arrival and departure window.
