★ COMPARISONS · COMMUTE · TRAIN VS DRIVING
On the defaults — 20 commuting days at $12.00 a day of train against 30 miles at $0.70 a mile plus $5.00 parking driving — train costs $240.00 a month and driving costs $520.00, so driving costs $280.00 more. This is the TRAIN version — a rail fare against the driving model — the bus-vs-driving page is the BUS version — a flat bus fare against the same driving model; the carpool-vs-driving-alone page is the CARPOOL version — splitting the drive against driving alone; and the work-from-home-vs-office page is the NO-COMMUTE version — staying home against the same driving model.
Put your days, train fare, miles, mileage rate and parking in: 20 days at $12.00 train cost $240.00 vs $520.00 driving.
It means that a month of commuting 20 days costs $240.00 by train at $12.00 a day, and $520.00 by driving 30 miles at $0.70 a mile plus $5.00 parking a day, so driving costs $280.00 more. The break-even fare is $26.00 a day: at $26.00 a day, 20 days of train cost exactly $520.00, the same as driving, so any fare below $26.00 wins for train and any fare above it wins for driving. The part people get wrong is comparing a single ride with a single drive and stopping there: one day the gap is only $14.00, which looks modest, but over 20 days it is $280.00, and over a working year it is about $3,360.00 — the monthly view is what turns a shrug into a decision.
Is $0.70 an honest all-in driving cost? The mileage rate carries the whole driving side: at $0.70 a mile, 30 miles cost $21.00 before parking, and the 15-mile branch drives for $310.00 against the $520.00 headline, so halving the distance saves $210.00 a month. If your real per-mile cost is fuel only, say $0.25, driving falls to $250.00 a month and beats train by $10.00 — the verdict flips on this one input. Price depreciation, insurance and maintenance into the rate, or the comparison is rigged for driving.
Does the $12.00 fare cover the whole journey? A rail fare that excludes the bus to the station, station parking, or a second leg understates the train side: a $12.00 fare plus $3.00 of station parking is really $15.00 a day, which costs $300.00 a month — still cheaper than driving here, but $60.00 closer. The $20.00-fare branch costs $400.00 and still wins, but the $30.00-fare branch costs $600.00 and loses to driving by $80.00, so a fare that averages $30.00 instead of $12.00 reverses the headline verdict. Enter the full door-to-door daily cost, not just the rail ticket.
What is your time worth on each side? This page compares money only, and the two sides buy different hours: a train hour can be worked, read or rested in, while a driving hour cannot. If the train leg is longer in clock time but usable, or the drive is shorter but stressful, the money winner may still be the wrong choice. Put a value on the hour each side gives back before deciding on $280.00 alone.
On the defaults: 20 days, $12.00 train fare a day, 30 round-trip miles, $0.70 a mile, $5.00 parking a day.
And the other way: the train fare behind $240.00 of train is $12.00 a day, the round-trip miles behind $520.00 of driving are 30 miles, and the parking behind $520.00 of driving is $5.00 a day.
The defaults are 20 commuting days, a $12.00 train fare, 30 round-trip miles, a $0.70 mileage rate and $5.00 parking, so the headline is a daily commuter with a moderate drive and cheap parking. The model is two multiplications and a subtraction: train is days times fare, driving is days times miles times mileage plus parking, and the gap is driving minus train. The fare reverse is checked at $2.00 either side, because $2.00 over 20 days is $40.00; the miles reverse is checked at 5 miles either side, because 5 miles at $0.70 over 20 days is $70.00; the parking reverse is checked at $5.00 either side, because $5.00 over 20 days is $100.00. The model does not include fixed car costs such as loan payments and insurance, monthly rail passes that discount the fare, or the value of the time each side frees up — add fixed costs to the driving side if the car exists only for commuting.

Figures are the model’s own arithmetic on the numbers you type, computed from unrounded values and displayed rounded HALF_UP to 2dp. The main limitation is the mileage rate, not the arithmetic: fuel-only rates understate driving, all-in rates overstate it if the car is kept anyway, and fares vary with station charges and passes. This page is a calculation tool, not financial advice.
20 days of train at $12.00 a day costs $240.00 a month vs $520.00 driving 30 miles at $0.70 a mile plus $5.00 parking: driving costs $280.00 more. Source: Bright Side Kit, https://brightoolbox.com/train-vs-driving/, accessed 29 October 2026.
Everything driving costs per mile: fuel, wear, depreciation, insurance and maintenance rolled into one figure. A fuel-only rate understates driving badly — at $0.25 a mile the same commute drives for $250.00 and barely beats train, while at $0.70 it drives for $520.00 and loses by $280.00.
Because driving costs $26.00 a day on the defaults: 30 miles at $0.70 is $21.00 plus $5.00 parking. A train fare of $26.00 a day over 20 days is exactly $520.00, the driving total, so fares below $26.00 win for train and fares above it win for driving.
Use your actual commuting days: the days branches show 10 days at $120.00 train against $260.00 driving, and 30 days at $360.00 against $780.00. The gap scales with days, so a hybrid schedule still favors whichever side is cheaper per day.
Only if you include it: enter the fare as your real average cost per day, station parking and feeder legs included. A $12.00 ticket plus $3.00 of station parking is really $15.00 a day, which costs $300.00 a month — still cheaper than driving here, but $60.00 closer.
They are excluded: this page prices the marginal cost of each commuting day. If the car exists only for commuting, add its monthly fixed costs to the driving side — a $300.00 payment alone would push driving to $820.00. If the car is kept anyway, the marginal view is the honest one.
When the fare stays below the $26.00 break-even, when parking is expensive, when the drive is long, or when the per-mile cost is honestly high. The $30.00-fare branch and the 15-mile branch show both flips: an expensive fare or a short drive hands the win back to driving.
