📖 Overview
Use this tool to include transportation overhead in your monthly budget.
🧪 Example Scenarios
Use these default and higher-pressure example inputs to explore how sensitive this calculator is before using your real numbers.
| Input | Base Case | Higher Pressure Case |
|---|---|---|
| Daily Commute Distance (km) | 34 | 39.1 |
| Cost Per Km ($) | 0.22 | 0.26 |
⚙️ How It Works
This estimates monthly commute cost from daily distance and per-kilometer cost, using a 22-workday month.
The Formula
Monthly Cost = Daily Distance (km) × 2 × Cost/km × 22 days
| Daily Distance | One-way commute distance in km |
| × 2 | Round trip multiplier |
| Cost/km | Combined fuel, wear, and running cost per kilometer |
| 22 days | Standard working days per month |
💡Average total running cost for a petrol car is roughly €0.15–0.25/km including fuel, depreciation, and maintenance. Electric vehicles typically run €0.05–0.12/km.
Quick Reference
| One-way km | €0.10/km | €0.15/km | €0.20/km | €0.25/km |
|---|---|---|---|---|
| 10 km | €44/mo | €66/mo | €88/mo | €110/mo |
| 20 km | €88/mo | €132/mo | €176/mo | €220/mo |
| 30 km | €132/mo | €198/mo | €264/mo | €330/mo |
| 50 km | €220/mo | €330/mo | €440/mo | €550/mo |
When To Use This
- Use this tool when you need a fast decision during active planning or execution.
- Use this before committing money, time, or tradeoffs that are hard to reverse.
- Use this to compare options using the same assumptions across scenarios.
Edge Cases To Watch
- Results can be misleading if key inputs are missing, stale, or unrealistic.
- Very small or very large values may amplify rounding effects and interpretation risk.
- If assumptions change mid-decision, recalculate before acting.
Practical Tips
💡 Update per-km cost when fuel prices shift.
💡 Include parking and tolls separately if needed.
💡 Use this number when evaluating remote or hybrid options.
