Erasmus can last from a few months up to a full academic year, but the real duration depends on programme limits, the partner university’s calendar, and the terms of your grant agreement. Below is a practical framework: permitted ranges, the most common choices, and what to do if you want to extend or shorten your stay.
Key takeaways
- Under Erasmus, a student can complete studies and traineeships abroad, provided they do not exceed the mobility limit.
- To apply for Erasmus study mobility, you must meet your university’s rules and submit required documents, including a motivation letter and a Learning Agreement for Studies.
- The Erasmus grant and social top-ups can help cover living costs at a foreign university, but they do not cover all expenses.
- Erasmus study mobility can last from 5 to 12 months, with an option to extend, provided conditions are met and funds are available.
- Students from less advantaged backgrounds and recipients of social scholarships may apply for additional support through the Erasmus office or the national agency.
What exactly does the “mobility period” mean?
An Erasmus+ mobility period for studies is the time during which a student completes an approved part of their programme at a partner university abroad, with related administrative settlement and (usually) funding. In Erasmus+, long-term study mobility generally lasts 2 to 12 months, and within one study cycle it cannot exceed the programme limit.
In practice, you may also encounter “minimum 3 months” (or “minimum 1 semester/trimester”)—this is usually a university organisational requirement rather than a contradiction of Erasmus rules. Therefore always check your university’s recruitment rules and the unit responsible for exchanges (often the international office) and the mobility regulations.

Erasmus in practice: one semester or a full academic year?
Most often, study mobility lasts one semester (about 4–5.5 months) or a full academic year (about 9–10 months). These are the two most popular formats because they fit best with the academic calendar and ECTS settlement.
Key rule: the partner university’s academic calendar matters more than your home university’s calendar. A semester may start earlier or later (e.g., in Finland classes can begin as early as late August). Before choosing a country and university:
- visit the partner university’s website,
- find “Academic calendar / Academic year,”
- check dates: start of classes, registrations, exam periods, resits, breaks.
This directly affects the dates in your agreement, the length of your stay, grant payment and settlement timelines, and housing planning.
Common Erasmus duration variants and what they imply
| Mobility variant | Typical duration | What determines start/end dates | What to check before leaving (specific) | Impact on grant and settlement |
|---|---|---|---|---|
| 1 semester | 4–5.5 months | partner calendar + exams | semester dates, exam session, resits, mandatory orientation/registrations | grant usually calculated by months/days in the agreement; easier credit recognition in one block |
| 2 semesters (academic year) | 9–10 months | continuity of two semesters at the same university | whether extension within one year is possible; coordinators’ signatures | more ECTS to agree in the Learning Agreement; higher risk of changes in course offerings |
How the 12-month limit and mobility “budget” work
You have up to 12 months of Erasmus+ mobility per degree level (Bachelor’s, Master’s, Doctorate), and up to 24 months for long-cycle master’s programmes. After exhausting the limit for a given level, you cannot apply for another mobility within the same “pool.”
Practical points to avoid traps:
- The limit is counted within each cycle (e.g., Bachelor’s separately, Master’s separately).
- Different mobility types (studies + traineeships) may be counted together if they are in the same cycle.
- If you plan a second trip (e.g., a second semester), calculate the total time before submitting documents.
Can Erasmus be outside the EU: Norway, Turkey, Serbia, North Macedonia?
Yes—Erasmus+ includes not only EU countries but also associated countries such as Norway, Turkey, Serbia and North Macedonia.
This matters for the duration of the trip because in addition to the academic calendar, organisational issues come into play:
- arrival time and formalities,
- documentation requirements of the partner university,
- potentially longer preparation (insurance, confirmations, local procedures).
Practical conclusion: if you choose these destinations, start earlier and do not assume timelines will be “like at your faculty.”
Can you extend Erasmus from one semester to a full academic year?
Yes, but an extension requires approval from both universities and must be reported no later than 30 days before the end date specified in your grant agreement. Also, funding for the extension depends on available funds—you may receive approval to continue without additional grant funding.
If you want to extend from one semester to a full academic year, use this checklist:
- Deadline: report your intent at least 30 days before the end of the agreement period.
- Document: prepare an extension request with signatures from coordinators of both universities.
- Scope: the extension usually must fit within one academic year (e.g., from winter semester to the full year).
- Insurance: if EHIC/accident/health coverage does not cover the extended period, obtain a new EHIC and buy insurance for the additional time.
- If the planned mobility period is longer than the funded period in your agreement, also report it at least 30 days in advance—then the university prepares an annex extending the funded period (if the budget allows).
What if you want to shorten the trip or withdraw completely?
Shortening your stay (e.g., from a full year to one semester) and withdrawal require a formal statement—usually submitted no later than 30 days before the end of the mobility at the receiving institution. This allows the university to offer the place to another participant and close the settlement.
In practice: the sooner you inform them, the lower the risk of problems with documents, grant settlement, and recognition of credits.
Why does “4 months” sometimes become “5.5 months”?
Length is most often determined by: start/end dates of the semester at the partner university, exam schedules, and administrative procedures (registrations, confirmations, issuing documents).
Typical situations that extend the real stay:
- mandatory orientation days before classes start,
- exams spread over several weeks,
- the transcript of records issued after the exam session,
- requirement to remain until the end of labs/seminars.
Therefore, do not plan your return “the day after the last class”—plan based on the end of academic obligations, not on assumptions.
How to set up your study programme and recognition: Learning Agreement and programme mapping
The Learning Agreement is the document describing courses taken abroad and ensuring recognition after return if the student completes the agreed programme.
To make it work without losing time in your study plan:
- choose courses from the partner university’s offer (with ECTS),
- agree what they replace at your home university (within the curriculum),
- the document is approved by three parties: the student, the sending institution, and the receiving institution.
Most important operational rule: agree everything with your coordinator and faculty coordinator before leaving. In practice, the coordinator at your faculty decides whether your proposed set of courses will be recognised after return.
Recruitment: when to start and what determines your timeline?
Recruitment usually starts several months before departure, and deadlines depend on your university’s schedule and the number of places in partner agreements. To avoid missing critical dates:
- check announcements from the responsible unit/international office (they contain detailed information),
- prepare documents early (CV, grades, approvals, forms),
- handle language requirements: these may include a minimum level, a test or certificate, and sometimes an interview.
From a practical perspective: if your university requires a minimum 3-month mobility but the partner university has a different semester structure, you must align the dates so that the mobility period meets both sets of rules.
Grant and travel costs: how do they influence the length of your stay?
The Erasmus+ grant is settled for the funded period specified in your agreement, while travel and living costs must be calculated separately—because the grant rarely covers all expenses. Many projects also include a travel cost lump sum dependent on distance and whether you choose “green travel” (e.g., train/bus) or standard travel.
A practical budgeting method for deciding your mobility length:
- calculate the minimum realistic stay: start of classes + exam period + formal end,
- add monthly fixed costs (housing, local transport, food),
- add one-off costs: deposit, start-up fees, tickets (travel costs), insurance, basic equipment,
- compare this to the grant amount stated in your agreement (not “average rates from the internet”).
Nearby specialist tip: how not to lose on dates when you travel or host students in Warsaw
The biggest logistical mistake is signing a lease “for a semester” when the partner university finishes classes and exams later than you assume. We recommend a simple rule: set accommodation dates according to the partner university’s academic calendar plus a buffer for exams and formalities—not according to “planned class dates.”
Three practical steps that reduce stress:
- Collect key dates (start of classes, end of exam period, possible resits) before booking a room or return ticket.
- Plan a 7–14-day buffer at the end of the trip: document pickup, administrative closures, move-out.
- If you are arriving in Warsaw as an international student, ask for clear terms: deposit, utilities settlement, conditions for early termination—this clarifies your budget and reduces the risk of extra charges.

Summary: how long does Erasmus last and how to calculate it without guessing?
Erasmus study mobility most often lasts 1 semester (4–5.5 months) or 1 academic year (9–10 months), and formally long-term mobility fits within up to 12 months and within the 12-month limit per study cycle.
If you want certainty about duration, do this in order:
- Check the partner university’s academic calendar on its website.
- Finalise the Learning Agreement/programme mapping with your coordinator and faculty coordinator.
- Align dates with your grant agreement and your university’s requirements.
- If you plan an extension or shortening—act in advance (minimum 30 days) and calculate settlement consequences.
