Interactive Erasmus KM Calculator
Estimate your Erasmus+ distance band and indicative travel support in seconds. Enter a distance directly, or calculate distance from coordinates first.

Optional helper: enter latitude/longitude for origin and destination, then copy the result into the calculator above automatically.
What is an Erasmus KM calculator?
An Erasmus KM calculator helps students, staff, project coordinators, and universities convert travel distance into the official Erasmus+ distance band. That band is then used to estimate travel support per participant.
In practice, this means one thing: if you know how far two locations are, you can quickly estimate the unit contribution your mobility project may receive.
How Erasmus+ distance bands work
Erasmus+ uses distance bands instead of reimbursing every exact transport cost. You calculate the one-way distance between origin and destination, then match that value to a funding band.
| Distance band (km) | Standard travel (EUR) | Green travel (EUR) |
|---|---|---|
| 10 - 99 | 23 | 23 |
| 100 - 499 | 180 | 210 |
| 500 - 1,999 | 275 | 320 |
| 2,000 - 2,999 | 360 | 410 |
| 3,000 - 3,999 | 530 | 610 |
| 4,000 - 7,999 | 820 | 820 |
| 8,000+ | 1,500 | 1,500 |
These values are commonly used reference amounts. Always verify your National Agency call, action type (KA1/KA2), and project year for final eligibility and rates.
How to use this calculator correctly
1) Enter the correct base distance
If you already know your one-way distance in kilometers, enter it directly. If the value you have is round-trip, tick the round-trip checkbox. The tool automatically converts it to one-way before assigning the Erasmus band.
2) Select travel type and participants
Choose standard or green travel and set the number of participants. The calculator multiplies the unit amount by participant count, giving you an immediate estimate for planning.
3) Use coordinate mode when needed
If you do not have a distance figure, the coordinate helper calculates great-circle distance from latitude and longitude using the Haversine formula. This is useful for early budgeting and route comparisons.
Common mistakes to avoid
- Using round-trip distance as one-way: this can push you into the wrong band.
- Assuming all calls use identical rules: project guides can differ by year and action.
- Ignoring minimum eligibility: distances under 10 km may not qualify for travel support.
- Mixing participant categories: some projects apply separate financial logic for different roles.
Example scenarios
Example A: Student mobility, standard travel
One-way distance: 1,450 km. This sits in the 500-1,999 km band, so estimated support is EUR 275 per participant. For 12 participants, estimated total is EUR 3,300.
Example B: Blended intensive programme, green travel
One-way distance: 2,450 km. This sits in the 2,000-2,999 km band, giving EUR 410 per participant for green travel. For 8 participants, estimated total is EUR 3,280.
Final planning tip
Use this calculator to get fast, practical estimates for drafting budgets, informing participants, and planning mobility scenarios. Then confirm all values with your institution and official Erasmus+ documentation before submission.
