Transit Ticket Optimizer
Planning a trip and unsure whether a weekly pass beats buying single fares every day? Enter your trip frequency, the length of your stay, and the local fares to instantly see the cheapest combination of single tickets and transit passes. The optimizer tests every possible mix of daily, weekly, and monthly passes and shows you the winning combination alongside the cost savings.
How the ticket optimizer works
The optimizer calculates your total trip count (trips per day multiplied by the number of days), then tests every possible combination of monthly, weekly, and daily passes alongside single tickets. For each combination, it adds up the cost of passes and any single tickets needed to cover leftover trips. The combination with the lowest total cost is your recommended plan. If no pass saves money, it tells you singles are cheapest.
Break-even thresholds explained
A daily pass breaks even when you take enough trips in a single day to exceed the pass price. Divide the daily pass price by the single fare to get that threshold. For example, a $8.00 daily pass and a $2.90 single fare break even at about 2.8 trips per day, meaning the pass pays off from 3 trips onward. A weekly pass breaks even when you use transit enough days in the week to beat stacking daily passes. Divide the weekly price by the daily price to get that day count.
Tips for getting the most from transit passes
Many cities sell passes that start from the moment you first tap them, not from midnight of that calendar day. Always check the validity window before buying. Some networks offer top-up cards (e.g., Oyster, Suica, PRESTO) where the system automatically applies the cheapest fare, removing the need to optimize manually. Reduced-price passes for seniors, children, and students can shift break-even thresholds significantly. If you are visiting multiple cities, calculate each city separately as fare structures vary widely.
Common transit pass types worldwide
Most urban rail and bus networks sell some combination of single fares, daily all-day passes, and 7-day or monthly unlimited passes. London uses 7-day Travelcards. New York City sells 7-day and 30-day MetroCards. Tokyo offers 1, 2, 3, and 14-day tourist passes on the Tokyo Metro. Berlin sells the AB day ticket, 7-day pass, and monthly pass. Paris has the Paris Visite pass in 1, 2, 3, and 5-day versions. The structure is similar everywhere: single fares reward infrequent riders, passes reward daily heavy users.
When does each pass type pay off?
| Trips per day | Stay length | Likely best option |
|---|---|---|
| 1-2 | 1-3 days | Single tickets |
| 3-4 | 1 day | Daily pass or singles (check break-even) |
| 3-4 | 4-7 days | Weekly pass |
| 4+ | 7+ days | Weekly pass (or monthly for 30+ days) |
| 2+ | 30+ days | Monthly pass |
| Any | Short event day | Daily pass if > break-even trips |

Frequently asked questions
What is a ticket optimizer?
A ticket optimizer is a tool that finds the cheapest combination of transit passes and single fares for a specific trip. Instead of manually comparing every option, you enter your trips per day, stay length, and local fares, and the optimizer tests all possible pass combinations to pick the lowest-cost plan.
How many trips per day should I count?
Count each one-way journey separately. A round trip - for example, riding from your hotel to a museum and back - counts as 2 trips. If you make two return journeys in a day you have 4 trips. Be honest about rest days or days you will walk or cycle: fewer trips can tip the balance back toward single fares.
Does the optimizer account for rest days when I won't use transit?
Yes. Enter your actual trips-per-day average across your whole stay, including rest days. If you plan 5 busy days and 2 quiet days in a 7-day trip, and you expect 4 trips on busy days and 1 trip on quiet days, your average is (5 x 4 + 2 x 1) / 7 = about 3.1 trips per day.
What if my transit system has no daily or weekly pass?
Toggle off the pass types that are not available. The optimizer will then compare only the options you have enabled. In many smaller cities only single fares exist, and the tool will confirm that singles are your only choice.
Can I use this for multi-city trips?
Run the optimizer separately for each city you visit, using the number of days you will spend there and the fares for that city. Then add up the costs across cities to see your total transit budget.
What if a pass is valid from midnight rather than from first use?
If your network sells calendar-day passes (valid until midnight rather than 24 hours from activation), the optimizer still applies because it counts passes by calendar day. However, if you arrive late in the evening you may effectively waste that day's pass value, so factor that in when deciding whether a daily pass is worth it.
Are reduced-fare passes accounted for?
Enter the price you will actually pay. If you qualify for a reduced-fare or tourist pass, use that price in the relevant field. The optimizer does not know about eligibility rules, so you need to enter the correct fare for your situation.
