By Cyril Kimbi“How long is a master’s degree?” has three different correct answers depending on which country you are asking about, and the gap between them is a full year of your life and a full year of fees. This guide gives the real durations by country and by mode of study, and explains why a British master’s finishes in twelve months while an American one often takes twenty-four.
The short answer by country
| Country or system | Full-time duration | Credit requirement |
|---|---|---|
| United Kingdom (taught MA/MSc) | 12 months | 180 UK credits |
| United States | 18-24 months | 30-60 semester credits |
| Europe / EHEA | 2 years | 120 ECTS |
| Cameroon and LMD countries | 2 years (M1 + M2) | 120 credits |
| Canada | 12-24 months | Varies by province and programme |
| Australia | 12-24 months | Depends on prior qualification |
Why the British master’s is shorter
It is not a lighter qualification; it is a differently packaged one.
A British taught master’s is 180 UK credits over twelve calendar months, against 120 credits for a full undergraduate year. It runs straight through the summer, with the dissertation written between June and September while American programmes are on vacation. There is also almost no general coursework: British undergraduate degrees are already specialised, so the master’s begins at depth immediately.
American programmes assume a broader bachelor’s degree, frequently require foundation courses, and are built around two nine-month academic years with a summer between them. The extra elapsed time is largely structural.
Taught versus research
This distinction predicts duration better than the country does.
- Taught master’s (MA, MSc, MBA, LLM) — modules, examinations, and a dissertation of 12,000 to 20,000 words. One year in Britain, two in most of Europe.
- Research master’s (MRes, MPhil, thesis-based MSc) — little or no coursework and a substantial thesis. Nominally one to two years; in practice frequently longer, because a thesis finishes when the research finishes.
If the funding runs for two years, a research master’s that drifts into a third is a genuine financial problem. Ask any prospective supervisor for the actual median completion time of their recent students, not the published one.
The M1 and M2 structure in Cameroon
Under LMD, the Cameroonian master’s is explicitly two stages:
- Master 1 (M1) — 60 credits, mostly taught, often with a short supervised project.
- Master 2 (M2) — 60 credits, specialised, built around a memoire and frequently a professional placement.
Two features of this structure matter more than students expect. Progression from M1 to M2 is not automatic in many faculties — M2 places are limited and selection is competitive, so a completed M1 can leave a student without a route onward in the same institution. And the memoire regularly determines whether the second year takes twelve months or twenty, because a defence that slips past the session date waits for the next one.
The M1/M2 split also maps cleanly onto European programmes, which is the practical benefit of LMD: a Cameroonian M1 is generally recognised as the first year of a European master’s rather than as a terminal qualification.
Part-time, online and accelerated routes
The rule of thumb is straightforward: part-time takes twice as long. A one-year British master’s becomes two; a two-year European one becomes four.
Online programmes vary far more. Some are simply the campus programme delivered remotely on the same calendar. Others are self-paced, and self-paced is where degrees quietly go to die — without cohort deadlines, a two-year programme can drift to five. Before enrolling on anything self-paced, ask what proportion of students complete within the stated time.
Accelerated routes do exist. Integrated “four plus one” programmes let a student begin master’s-level courses in the final undergraduate year and finish the master’s in a fifth year. They require planning from about the second undergraduate year, so they are only useful to students who decide early.
What actually makes a master’s run long
Programme length is the advertised number. The delays are almost always one of four things:
- Prerequisite gaps. Entering a quantitative programme without the assumed statistics or mathematics background typically adds a semester of foundation courses that carry no credit towards the degree.
- The dissertation. The most common single cause. Data collection slips, ethics approval takes longer than planned, a supervisor is on sabbatical.
- Funding and work. Students who take on employment mid-programme often drop to part-time without deciding to.
- Course sequencing. A required module offered only in the spring, missed once, costs a full year rather than a semester.
The last one is worth checking before you register. Ask which required modules run only once a year, and treat those as fixed points in your plan.
Do you need a master’s before a doctorate?
It depends on the system. In the United States, many PhD programmes admit directly from a bachelor’s degree and award a master’s along the way after the qualifying examination — so a separate master’s is often unnecessary and occasionally counterproductive.
In Britain, Europe and the LMD countries, a master’s is normally required before doctoral registration. Under LMD specifically, the M2 with a completed memoire is the standard entry route to the Doctorat.
Frequently asked questions
How long does a master’s degree take?
One to two years full-time: 12 months in the United Kingdom, 18-24 months in the United States, two years in Europe and under the LMD system.
How many years is an MSc?
One year in Britain, two years in most of continental Europe and in Cameroon. A research-based MSc can run longer.
How many credits is a master’s degree?
30 to 60 semester credits in the United States, 180 UK credits in Britain, and 120 ECTS or LMD credits in Europe and Cameroon.
Is a one-year master’s respected?
Yes. British one-year master’s degrees are long established and widely recognised, including by employers and universities that run two-year programmes themselves. What matters is the accreditation of the institution.
Can I do a master’s while working full time?
Commonly, through part-time or executive programmes designed for it. Expect roughly double the elapsed time and a genuine 15-20 hours of study a week.
