Metro Fare Calculator: 20 Rides Cost $50.00 a Month
On the defaults — 20 rides a month at $2.50 a ride — a metro fare is $50.00 a month, or $600.00 a year. This is the metro fare tool: multiply the rides by the fare a ride for the monthly fare, then stretch it to the week and the year — a month guessed from the rides alone tells you nothing until the fare behind it is known.
What does $50.00 a month, $600.00 a year mean?
It means twenty metro rides in a month, at two dollars and fifty cents a ride, cost fifty dollars in the month, which is eleven dollars and fifty-four cents a week and six hundred dollars in the year. The rides set the monthly count, the fare sets the cost of each trip, and the week and year are fixed stretches of the month: one more ride adds a full fare without raising any other ride, a dearer fare raises every ride without taking a single extra ride, and a cheaper fare lowers the whole month by the difference on every ride. The only judgement is the rides — 20 must be the rides actually taken, not the rides planned, and the rides that settle the fare are the ones on the turnstile actually travelled, missed trains and extra trips included, not the commute plan alone.

| Monthly fare | rides × fare a ride | $50.00 — 20 × $2.50. |
| Weekly fare | monthly × 12 ÷ 52 | $11.54 — $50.00 × 12 ÷ 52. |
| Yearly fare | monthly × 12 | $600.00 — $50.00 × 12. |
Three things to check before you trust the number
First, check the rides honestly: 20 rides must be the rides actually taken, including the extra trip downtown on Saturday that the commute plan never showed — a month counted at 20 while 24 were taken costs ten dollars more than the figure shows. Second, check the fare against the fare chart, not the memory: $2.50 must be the fare actually charged, because a fare remembered at $2.00 that now bills at $2.50 lifts the month by ten dollars. Third, check the month against the pass: $50.00 must be set against the monthly metro pass price, because a pass below $50.00 beats paying per ride at these rides, while a pass above it loses — and the fare here is the single-ride fare only, before any pass discount, which the operator applies on top.
Worked example
20 rides, $2.50 a ride. Monthly: 20 × $2.50 = $50.00. Weekly: $50.00 × 12 ÷ 52 = $11.54. Yearly: $50.00 × 12 = $600.00. In practice that means a regular metro rider pays about fifty dollars a month for the trips — the number to set against a monthly pass, and the weekly figure to use when an extra trip is weighed against a cheaper fare.
Every branch, checked
At 30 rides instead of 20, the fare rises to $75.00 a month — $17.31 a week, $900.00 a year. At $2.00 a ride instead of $2.50, the fare falls to $40.00 a month — $9.23 a week, $480.00 a year. At 10 rides instead of 20, the fare falls to $25.00 a month — $5.77 a week, $300.00 a year. At $3.25 a ride instead of $2.50, the fare rises to $65.00 a month — $15.00 a week, $780.00 a year.
The reverses, worked backwards
The rides behind $50.00 are 20: at 10 rides the fare is $25.00; at 30 rides it is $75.00. The fare behind $50.00 is $2.50: at $2.00 a ride the fare is $40.00; at $3.25 a ride it is $65.00 — the fare never touches the ride count, only the cost of each trip.
What the defaults assume
The defaults assume 20 rides at a flat $2.50 a ride with no pass discount, peak surcharge, or transfer fare. They do not assume a monthly pass, a concession discount, or a free travel day — a rider on a pass pays the pass price, not $50.00, so treat $50.00 as the pay-per-ride month, not the pass month.
Who uses this
- A commuter checking a monthly cost: the $50.00 settles what the metro really costs.
- A budgeter auditing transport costs: the ride lever shows what one more trip really adds.
- A traveller comparing metro and bus: the $11.54 a week is the line to set against the bus pass.
- A household weighing a car against the metro: the $600.00 a year is the line to set against driving costs.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the rides actually taken and the fare actually charged. Real metro fares vary with peak pricing, zones, transfers, and discounts — so treat $50.00 as the planning fare for 20 rides at a true $2.50, and check it against one real month of trips before quoting it to anyone else.

Frequently asked questions
How much is a metro fare for 20 rides a month?
$50.00 a month on the defaults: 20 rides × $2.50 = $50.00, which is $11.54 a week and $600.00 a year.
Why is the yearly fare twelve times the monthly fare?
Because the year is twelve months at the same monthly rate: $50.00 × 12 = $600.00. The weekly figure instead spreads the year over 52 weeks, which is why it is $11.54 rather than a quarter of the month.
Does a monthly metro pass change the maths?
Only the comparison: enter the rides and fare as usual, then set the $50.00 against the pass price. If the pass costs less than $50.00, the pass wins at these rides.
How much does one extra ride cost?
$2.50 exactly at these defaults — one full ride of fare, because the monthly fare scales with the rides at the same fare.
Is the fare different at peak times?
Only through the fare input: enter the peak fare instead of $2.50 and every figure follows. The rides stay exactly the same.
How is this different from the subway fare calculator?
That page prices subway rides by the ride across a month; this page prices metro rides by the ride across a month. Use that page for the subway, this page for the metro.
