Formula used
Pay-as-you-go cost = discounted rail fares + discounted bus fares − transfer credits + parking + regional transit + other costs.
Pass-plan cost = pass price + rail overages + premium-bus overages + parking + regional transit + other costs.
Rail overage = max(0, one-way rail fare − selected fare level) × affected trips.
Monthly savings = pay-as-you-go cost − pass-plan cost.

Example calculation
A rider commutes twenty days monthly. Each workday includes two four-dollar rail trips. The calculator compares those fares against several monthly pass tiers.
| Example input | Value | Purpose |
|---|---|---|
| Commute days | 20 | Determines routine rail trip counts. |
| Morning fare | $4.00 | Sets morning paygo cost and overages. |
| Evening fare | $4.00 | Sets evening paygo cost and overages. |
| Trips per day | 2 | Creates forty routine rail trips. |
| Employer subsidy | $0.00 | Keeps gross and personal savings equal. |
Coverage, assumptions, and limitations
The estimator treats regular Metro Bus rides as pass-covered. It applies configured credit toward express and premium buses. Regional transit and parking remain outside pass coverage calculations.
Station fields identify routes but do not fetch live fares. Enter the official fare shown for each planned trip. Editable values keep future fare changes easy to manage.
Results are planning estimates, not purchase guarantees. Fare programs can have separate eligibility and payment requirements. Always confirm current details directly with WMATA before purchasing.
Configured fare-table date: 2026-07-01. Monthly pass tiers use the editable fare-level multiplier.
Frequently asked questions
What does the monthly pass comparison include?
It includes rail, bus, parking, and other entered costs. It also calculates overages above the selected pass level. Employer subsidies appear separately for clearer personal budgeting decisions.
Why can a lower pass tier cost less?
A lower tier has a smaller purchase price. Some riders save despite paying occasional rail fare differences. The tier table reveals those tradeoffs before pass selection.
Does the pass cover every rail trip?
It covers rail trips through the selected fare level. Higher fares create a difference payable through Stored Value. Review the overage estimate before choosing your final tier.
Are regular Metro Bus trips included?
The calculator treats regular Metro Bus trips as included. Premium services receive only the configured fare credit amount. Change that credit whenever official coverage rules are updated.
Are regional transit partner trips covered?
No regional partner coverage is assumed by this calculator. Enter those monthly costs in the regional transit field. They remain visible within both payment method comparisons here.
How are reduced fares handled?
Eligible rider presets apply a fifty-percent paygo discount estimate. Reduced fares round downward to the nearest five cents. Pass discounts remain separate because program rules can differ.
How are employer benefits handled?
Employer subsidies reduce the estimated personal transportation cost. Employee pre-tax contributions reduce additional card payment requirements. Those contributions still remain part of personal spending totals.
What is the break-even trip count?
It estimates trips needed to recover the pass price. The calculation uses average value covered by the pass. Mixed trip patterns can change the displayed break-even point.
Why does purchase timing matter?
Monthly passes follow calendar-month activation rules. Later purchases can move validity into the following month. The cutoff remains editable for policy updates and verification.
Is the Stored Value buffer an expense?
No, the suggested buffer is not added as consumption. It remains available for overages and later individual trips. The result shows required and preferred buffer amounts separately.
Can I compare hybrid work schedules?
Yes, results include one-through-five-day office schedule estimates. Leave deductions apply across every displayed schedule scenario. The chart makes changing commute economics easier to compare.
