How to work out what your commute really costs each month
Most people underestimate their commute because they think of it as a daily fare or an occasional fuel fill. Add it up across a month and it can influence where you live or which job you accept. The numbers below are a made-up example to show the method, so use your own figures in the commute cost calculator.
Step 1: the cost of driving
Monthly fuel cost = one-way distance × 2 × travel days ÷ mileage × fuel price. Suppose you ride 15 km each way, 22 days a month, on a two-wheeler doing 40 km per litre, with petrol at ₹100 a litre:
15 × 2 × 22 ÷ 40 × ₹100 = ₹1,650 for fuel
If parking costs ₹50 a day, that is another ₹1,100, bringing the visible total to ₹2,750. Check your real mileage rather than the brochure figure. Stop-and-go traffic can pull it well below the advertised number. To measure it, fill the tank, note the odometer, and divide the distance at the next fill by the litres you added.
Step 2: add what the calculator leaves out
Servicing, insurance, tyres, repairs and the fall in the vehicle's value are real costs, even if they arrive once or twice a year. Add up what you spent on these over the past year and divide by 12. Tolls and the occasional fine go here too. It is a rough number, but a rough number beats leaving it out.
Step 3: the cost of public transport
Note your actual return fare, including any auto or cab to and from the stop. If that comes to ₹80 a day, the month costs ₹80 × 22 = ₹1,760. Check for passes if you travel most days, since a pass or smart-card discount can change the sum. Use the current figures from the operator. Our BMTC route finder and sister site blrmetro.com can help you plan the route.
Step 4: put a value on your time
Now time each option from door to door, including walking and waiting. If driving takes 45 minutes each way and the bus and metro take 70, the cheaper option costs an extra 50 minutes a day. Over 22 days, that is about 18 hours a month. Some people can read or rest on a train, which makes that time less costly. Riding in heavy traffic is rarely restful, so the comparison isn't simply minutes against minutes.
Step 5: compare whole situations
- A new flat. Slightly higher rent near a metro station or your office can be cheaper overall. Add rent and commute together for each option.
- A new job. A bigger salary with a much longer commute may give you less than it seems. Compare what's left after commuting costs, and think about the hours too.
- Mixed trips. A short ride to a station plus the metro can beat either option alone. Include the cost of parking at the station.
- Hybrid work. Enter the days you actually travel. Three days a week is about 13 days a month, which changes whether a monthly pass is worth it.
Review it after any change
Fuel prices, fares and routes change, and so does your routine. A quick rerun takes two minutes whenever you move, change jobs or see fares revised. Keep in mind that this is a planning estimate, and our tool doesn't use live prices: every figure comes from you.
