Commute cost and time comparison

Compare two commute options using their total monthly costs and daily roundtrip minutes. See the money and time differences.

Start with your own numbers

Editable example

An example is filled in. Replace it with your own data to calculate.

Treat the two ways of commuting as options A and B. Enter each whole-month cost and full daily roundtrip minutes. The commute days apply to both; monthly costs are not multiplied again.

Option A: total monthly commute costEnter the whole month’s commute cost, for example 1200, including the pass or fixed costs you want to compare. Do not enter a single-trip fare.

Option A: roundtrip minutes per dayUse the full daily trip from leaving home to returning, for example 90 minutes. Include walking, waiting, transfers and finding parking.

Option B: total monthly commute costEnter the whole month’s commute cost for option B, for example 5000. Use the same currency and amount units as option A.

Option B: roundtrip minutes per dayCompare the same complete roundtrip as option A, for example 50 minutes. Do not enter one-way or in-vehicle time alone.

Commute days this month for both optionsUse the same month and the same number of commute days, for example 20. Days scale the time totals; monthly costs are not multiplied again.

Example result

Option B costs more per month

3,800currency units

The main answer states how much more or less option B costs each month. A negative time gap means B saves time. Extra cost per hour saved is not guaranteed income.

Option A monthly cost1,200 currency units

Option B monthly cost5,000 currency units

Option A monthly commute time30 hours

Option B monthly commute time16.67 hours

Time gap: B minus A (negative means B saves time)-13.33 hours

Understanding these inputsThe faster option costs more. The amount below is extra cost per hour saved, not income.

Extra cost per hour saved with the faster option285 currency units/hour

Worked steps

90 × 20 ÷ 60 ≈ 30
50 × 20 ÷ 60 ≈ 16.666667
5000 − 1200 ≈ 3800
3800 ÷ 13.333333 ≈ 285

Monthly commute hours = daily roundtrip minutes × commute days / 60. The cost gap is B’s monthly cost minus A’s; the time gap is B’s monthly hours minus A’s. Costs are whole-month totals entered by you, not multiplied by commute days or automatically prorated. Use one currency, one amount unit and the same commute days for both options. Include walking, waiting, transfers and parking time. Only when the faster option also costs more is the extra monthly cost divided by hours saved. Equal costs or times are handled without dividing by zero. Extra cost per hour saved is not income or a recommendation. Examples are synthetic, not current fares or traffic. No address, route, fare, depreciation, comfort or safety estimate is made.

Method and scope

Monthly commute hours = daily roundtrip minutes × commute days / 60. The cost gap is B’s monthly cost minus A’s; the time gap is B’s monthly hours minus A’s.

Costs are whole-month totals entered by you, not multiplied by commute days or automatically prorated. Use one currency, one amount unit and the same commute days for both options. Include walking, waiting, transfers and parking time.

Only when the faster option also costs more is the extra monthly cost divided by hours saved. Equal costs or times are handled without dividing by zero.

What this helps you do

Compare two ways of making the same commute using monthly spending and total travel time. Option A and B can be transit, driving, cycling or another mode. You supply both estimates; no location or salary is needed.

What to enter

Enter each option’s whole-month cost in the same currency and units, then its complete daily roundtrip minutes. Include walking, waiting, transfers and parking. Use the same month and number of commute days. Monthly pass and fixed costs must already be included in your monthly total.

How it is calculated

Monthly hours = roundtrip minutes per day × commute days / 60. Subtract A from B for the cost and time gaps. When one option is faster but more expensive, extra cost per hour saved = absolute cost gap / absolute hours saved. This is an arithmetic comparison, not an official valuation rate.

Worked example

Synthetic example: 20 commute days, A costs 1200 per month and takes 90 minutes per day, while B costs 5000 and takes 50 minutes. B costs 3800 more and saves about 13.33 hours per month. That is 285 extra currency units per hour saved, not extra income.

Understanding the answer

The main answer states whether B costs more or less each month. A negative B-minus-A time gap means B saves time. When one option uses less money and less time, the page says so without assigning a value to comfort or reliability. Equal costs or times do not produce an infinite or invented hourly rate.

Scope and limitations

This compares one matched month with 1–31 whole commute days, costs from 0 to 1 billion, and roundtrip times from 0 to 1440 minutes per day. Costs are not automatically prorated by days. Future traffic, route safety, pass eligibility, ownership changes and the ability to earn money in saved time are outside scope. Inputs and plans stay in this browser.
