For a 7-day trip, parking at 15 a day comes to 105 — versus a 45 train round-trip or 80 in taxis. The right answer depends on trip length: short trips favour parking, long trips favour public transport.
What the result means
The cheapest option is shown with savings against the next-best. Time and convenience cost are not modelled — factor them in alongside the financial answer.
Quick example
With taxi round-trip cost of 80 and train round-trip cost of 45 (plus parking per day of 15 and trip days of 7), the result is 45.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.
Which inputs matter most
You enter Taxi Round-Trip Cost, Train Round-Trip Cost, Parking Per Day, and Trip Days. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
What's happening under the hood
Each option's total cost is computed; the lowest is the recommended option. Savings shown are against the next-cheapest option. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.
Using this without guilt
The figure here isn't a verdict on whether the spending is "worth it". That judgment is yours to make. What the number does is shift the question from "can I afford this?" to "is this what I want my money doing over a decade?". Both questions matter.
What this doesn't capture
The tool prices the money; it can't weigh the enjoyment. A coffee habit, gym membership, or streaming bundle might cost what the math says but deliver value that's harder to quantify. Use the number to make the trade-off visible — the decision is yours.
