How this is calculated

Fuel savings use your vehicle's EPA combined MPG estimate and the current Massachusetts average gas price from AAA. Maintenance savings apply the AAA 2025 variable rate per mile (~10–11¢/mile by vehicle type), covering oil changes, tire wear, and related repairs — costs that genuinely decrease when you drive less. Fixed costs like insurance, depreciation, registration, and finance charges are excluded — those don't change based on how many days you drive, so including them would overstate your actual savings. MBTA fares are current as of March 2026 from mbta.com/fares; the calculator automatically compares monthly pass vs. per-ride cost and uses whichever is cheaper for your frequency. Health estimates use MET values from the American College of Sports Medicine: cycling at a moderate pace (~12 mph) is approximately 8 METs; brisk walking is approximately 4 METs.

Common questions about active commuting in Massachusetts

How much money can I save by biking or walking to work in Boston?

On a typical 7-mile Boston-area commute, choosing to bike or walk three days a week puts roughly $900–$1,500 back in your pocket per year in fuel and maintenance savings — more if you're paying for parking. The maintenance savings surprise people: oil changes, tire wear, and brake replacement accumulate meaningfully over a full year of daily driving. At roughly 10–11 cents per mile, three active commute days a week on a 7-mile route saves around $175–$190 in maintenance alone, before you touch the gas budget.

How does biking to work compare to driving in Boston traffic?

On many Boston-area routes, a bike commute is surprisingly competitive with driving. Boston consistently ranks among the most congested cities in the US, with downtown speeds averaging 12–16 mph during peak hours. A cyclist averaging 10–12 mph on a 5–7 mile urban route can match or beat door-to-door driving time once parking and walking are included. For routes from neighborhoods like Somerville, Cambridge, or Jamaica Plain into the core, cycling often takes the same time or less. E-bikes close the gap further for hillier routes or longer distances.

What health benefits do I get from an active commute?

A 7-mile bike commute at a moderate pace burns roughly 400–500 calories and delivers about 45 minutes of moderate cardiovascular exercise — equivalent to a solid gym session. Doing this three days a week adds up to 100+ active minutes and 1,200+ calories per week, which meets or exceeds the American Heart Association's weekly physical activity recommendations. For people who struggle to find time to exercise, commuting actively is often the most sustainable way to build consistent movement into an already-structured day.

Is the MBTA a reliable alternative to driving for Boston-area commuters?

It depends heavily on your route. The Red, Orange, and Green lines serve dense corridors well and are genuinely competitive with driving for many downtown-bound commutes. Bus routes vary significantly in reliability, though key routes — particularly the 86, 1, 39, and Silver Line — have improved with dedicated bus lanes. The monthly LinkPass at $90 covers unlimited trips on all subway, bus, and Silver Line routes. For a commuter making 40+ trips a month, the pass pays for itself in under three weeks of use.

What's the best way to start commuting by bike if you're new to riding in traffic?

The most common approach is to start on lower-traffic parallel routes before gradually building confidence on main roads. The Boston region has an expanding network of protected bike lanes, and tools like the MassDOT bike map show low-stress routing options. Many new commuters find it helpful to do a dry run on a weekend first. E-bikes make a significant difference for hillier routes or longer distances — they remove the exertion concern and let you arrive without breaking a sweat. Green Streets Initiative's Shift app is designed to help people in exactly this situation: discover routes, build confidence, and see the real-world results of their choices.

How much does parking cost in Boston and Cambridge?

Daily parking rates in the Boston area vary significantly by neighborhood. Downtown Boston and the Seaport typically run $28–$35 per day. Back Bay and the South End average $22–$28. Cambridge near Kendall Square runs $18–$25. Somerville, Medford, and inner suburban areas typically range from $10–$16. Monthly garage parking in downtown Boston averages $350–$500/month. Many employers subsidize or provide free parking — which is why this calculator asks about your actual situation rather than assuming you pay market rate.
