What is {primary_keyword}?
The {primary_keyword} helps commuters in Washington DC estimate how much they will spend on Metro transportation each month. It is useful for anyone who rides the Metro regularly, whether you are a daily commuter, a student, or an occasional traveler.
Common misconceptions include assuming that the cash fare is always cheaper than a monthly pass, or that discounts apply uniformly across all routes. This calculator clarifies those assumptions with real numbers.
{primary_keyword} Formula and Mathematical Explanation
The core formula compares two cost structures:
- Pay‑per‑ride cost: Total rides per month × (Cash fare – Discount)
- Monthly pass cost: Fixed price of the unlimited pass.
The calculator then determines which option yields the lower monthly expense.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| R | Average rides per day | rides/day | 0‑10 |
| D | Travel days per month | days/month | 0‑31 |
| C | Cash fare per ride | $ | 2.00‑6.00 |
| P | SmarTrip discount percentage | % | 0‑20 |
| M | Monthly unlimited pass price | $ | 70‑100 |
Practical Examples (Real-World Use Cases)
Example 1: Daily commuter
Inputs: 2 rides/day, 22 days/month, cash fare $2.25, discount 10%, monthly pass $81.
Pay‑per‑ride cost = 2 × 22 × (2.25 × 0.90) = $89.10. Monthly pass = $81. Result: The pass saves $8.10 per month.
Example 2: Part‑time student
Inputs: 1 ride/day, 12 days/month, cash fare $2.25, discount 10%, monthly pass $81.
Pay‑per‑ride cost = 1 × 12 × (2.25 × 0.90) = $24.30. Monthly pass = $81. Result: Pay‑per‑ride is cheaper by $56.70.
