An ECTS credit is not a seat in a classroom — it is a unit of your life. One credit represents the total work a course demands: lectures, labs, assignments, revision and exams. This ECTS workload calculator multiplies your credits by the hours-per-credit convention your country or university uses — 25 hours in Spain and much of Europe, 26 or 30 in others, always within the ECTS range of 25–30 — and spreads the total over your semester’s weeks, so a course catalogue entry becomes an honest answer to “how much of my week is this degree?”.
What a credit actually measures
The European Credit Transfer and Accumulation System defines a full academic year as 60 ECTS and one credit as 25–30 hours of total student workload; each country and university fixes its own point in that range (Spain at 25, Germany commonly at 30). Workload includes everything the course demands of you — contact hours are often only a third of it. That is why two 6-credit courses can feel completely different in class yet should, on paper, cost the same 150–180 hours of your semester: the one with fewer lectures expects more independent study, and a course that demands far more or far less than its credit value is a course whose credits are mislabelled.
Worked example
A standard 30-ECTS semester at 25 hours per credit: total workload = 30 × 25 = 750 hours. Spread over a 15-week semester that is 50 hours a week — more than a full-time job, which is the first surprise the calculator delivers to most students, and the reason “I only have twelve hours of lectures” is no evidence of a light semester. At 30 hours per credit the same semester totals 900 hours, 60 a week. A single 6-credit course at 25 hours per credit is 150 hours — 10 hours a week over 15 weeks — of which perhaps 4 are lectures and 6 are the reading, problem sets and exam preparation the credit is actually counting.
Using the number honestly
The weekly average is a planning floor, not a schedule: workload is lumpy, with assessment weeks running far above the mean, so a student who studies “the average” each week is behind by design in week twelve. Count your weeks truthfully too — if your semester has 12 teaching weeks plus an exam period, the workload does not shrink to fit; it concentrates. For exchange students the conversion also works as a reality check in reverse: a home university that expects 45–50 hours a week and a host whose credits are valued at 30 hours are describing genuinely different intensities for the same 30 ECTS, and your learning agreement is where that difference should be faced, not your first exam session.
ECTS workload — frequently asked questions
How many hours is 1 ECTS? Between 25 and 30 hours of total student workload, fixed by your country or university within that band — 25 in Spain, up to 30 in Germany and the Netherlands. Check your programme’s official documents for its exact figure and enter it as a custom value.
Is a 60-ECTS year really a full-time job? Yes, by design: 60 credits × 25–30 hours = 1,500–1,800 hours a year, comparable to full-time employment hours, which is precisely the equivalence the system was built to express.
Do contact hours count double or separately? They are included in the total, not added to it. A course with 40 contact hours inside a 150-hour credit value expects roughly 110 hours of your own work around them.
Can I convert ECTS to US credit hours? As a rule of thumb, 2 ECTS ≈ 1 US semester credit hour, and a 60-ECTS year ≈ a 30-credit US year. Institutions confirm their own conversions for transfers; treat the ratio as orientation, not entitlement.
