Find the Ride Where a Transit Pass Starts Paying — Free
Pass decisions are made with a rough feeling about how often you travel, and the feeling is usually wrong by about eight rides a month. Multiply your real ride count by the real single fare, put the pass next to it, and the answer is one number — plus the ride count at which the two swap places, which is the figure you can keep in your head all month.
The proof surface
Free path: the card computes locally in the browser with no key and no account. Where an AI step helps, any free chat assistant works — Google AI Studio's free tier and Groq's free tier were both no-card and rate-limited when this page was reviewed on 2026-09-13 (limits change; check before you rely on them).
Why the flat version breaks
A fare table cannot help, because it prices one ride at a time. A pass page shows one price and no comparison. The missing step is arithmetic: rides times fare, against the pass, with the crossover point stated.
How to find the break-even in four passes
Four weeks is close enough, and a week of counting beats a year of guessing. Include the two-ride return trips and the evening journeys — those are what push a light traveller onto the pass.
Single fares are zoned. A pass comparison built on a zone-1 fare is the most common way people talk themselves into a pass they do not need.
The readout tells you how many rides make the pass worth it. If your month has fewer, buy singles; if it has more, buy the pass — and you can re-check the same number on any day of the month.
Some passes exclude airport links, night services or the bus you take on Fridays. Add those fares to the pay-as-you-go side; the comparison is only honest if both sides cover the same journeys.
SAMPLE DATA, NOT A VERIFIED CLAIM: Zone 1–2 · 46 rides · 2.90 single · 78.00 pass · break-even around 27 rides. Replace these values with your own source before you rely on anything.
What breaks first
Counting your busiest week
A conference week and a holiday week average out. Count a normal week, then adjust once you have two or three months of the real number.
Ignoring the fare cap
Many networks cap daily or weekly spending, which makes the pay-as-you-go side cheaper than the plain multiplication suggests. Check whether a cap applies and enter the capped figure for the rides field instead.
Buying the pass for the discount feeling
If the break-even count is above your real usage, the pass is a subsidy to the operator. The card will say so plainly, and that is the point of running it before payday.
What you pay otherwise
| The usual route | What it leaves out | Cost |
|---|---|---|
| An unused monthly pass | The whole month's pass price for travel you did not make | the pass, every month |
| The wrong zone band | The wider pass priced for a journey you make twice a year | a higher band all month |
| Deciding on the platform | A pass bought in a hurry against a ticket machine queue | a rushed commitment |
| This page + the free fare gate gauge | Computed in your tab, result on screen before you type anything | $0 |

A 46-ride month is already compared against a 78.00 pass, with the break-even count shown. Drop the ride count to 18 and the ranking flips on the tracks.

Both totals, the difference, the break-even ride count and the state link, with no account.
Both sides, the difference and the break-even count stay free. The one-time tier adds the printable gauge with a month log plus the saved comparisons behind it.
Boundary: This compares the fares you enter and does not know your network's rules. Caps, off-peak pricing, zone boundaries and eligibility discounts all change the answer — check the operator's own fare table before buying.
