Cambridge English estimates the guided learning hours needed to reach each level of the Common European Framework of Reference (CEFR). They are averages: your first language, age, exposure outside class and motivation all change the real time. Independent practice usually adds to class hours.
How to use the English Learning Time Calculator
- Current level
- Target level
- Lesson / study session length
- Sessions per week
Results update as you type, and every field accepts the units shown in its menu.
How it works
Choose your current and target levels and enter the length of each lesson or study session and how many you do per week.
Tips
- Track a typical week before planning – real figures beat estimates.
- Break big tasks into smaller pieces and plan buffer time for interruptions.
- Re-run the numbers when your inputs change so plans stay realistic.
- Use results as a guide for decisions, not as a precise prediction.
Common mistakes to avoid
- Counting calendar days when the deadline is in working days (or the reverse).
- Forgetting breaks, setup and handover time.
- Assuming every day is as productive as your best day.
Inputs explained
| Field | What to enter |
|---|---|
| Current level | Choose one: Beginner (pre-A1), A1, A2, B1 … |
| Target level | Choose one: Beginner (pre-A1), A1, A2, B1 … |
| Lesson / study session length | Units: h, min |
| Sessions per week | A number |
What each result means
- Study hours needed = max([Target level] – [Current level], 0)
- Study hours per week = [Lesson ÷ study session length]×[Sessions per week]
- Time to reach target = [Study hours needed]÷[Study hours per week]
- In months = [Time to reach target]÷4.345
Example values
How the main result changes when Lesson / study session length changes and everything else stays at the example values above:
| Lesson / study session length (h) | Time to reach target (weeks) |
|---|---|
| 0.75 | 267 |
| 1.13 | 178 |
| 1.5 | 133 |
| 1.88 | 107 |
| 2.25 | 89 |
| 3 | 67 |
Formula
Hours needed ≈ cumulative guided hours (target) − cumulative hours (current)Cumulative guide: A1 ≈ 100, A2 ≈ 200, B1 ≈ 400, B2 ≈ 600, C1 ≈ 800, C2 ≈ 1,100 hoursWeeks = hours needed ÷ study hours per weekWorked example
Inputs — Current level: Beginner (pre-A1); Target level: B2; Lesson / study session length: 1.5 h; Sessions per week: 3.
Results — Study hours needed = 600 hours; Study hours per week = 4.5; Time to reach target = 133 weeks; In months = 30.7.
Key terms
- CEFR
- Common European Framework of Reference for Languages.
Frequently asked questions
How long does it take to reach B2 in English?
About 500–600 guided hours from scratch – roughly 3–4 years at 3 hours a week, or under a year with intensive study.
What is CEFR?
The Common European Framework of Reference for Languages, with six levels from A1 (beginner) to C2 (mastery).
Do these hours include homework?
They are guided learning hours; independent practice speeds progress.
What formula does the English Learning Time Calculator use?
Hours needed ≈ cumulative guided hours (target) − cumulative hours (current).
