What this result does not account for
- Bands priced at each rung's lower edge, from Cambridge's English estimates
- Guided-hour lane only — self-study hours are margin, not table
In short: Cambridge's guided-learning-hour estimates put A2 near 180–200 hours, B1 at 350–400, B2 at 500–600, C1 at 700–800 and C2 at 1,000–1,200. At 250 hours you stand in A2 territory with 100.000000 guided hours to B1's doorstep — 20.000000 weeks at five hours a week. The ladder is the honest frame: B2 is the university-and-work threshold, and the C1–C2 stretch costs more hours than everything below it.
Formula
band = f(cumulative guided hours) ··· gap = next threshold − hours ··· weeks = gap ÷ hours/week
The CEFR describes what you can do, not how long you sat; the hour figures are Cambridge's guided-learning estimates for English from absolute beginner — A2 near 180–200 hours, B1 at 350–400, B2 at 500–600, C1 at 700–800, C2 at 1,000–1,200. This page bands at each rung's lower edge and prices the gap to the next. Two honest caveats travel with every hour table: the figures are English-classroom centered, and the cost depends on the language pair — the US Foreign Service Institute puts close languages near 600–750 hours to professional working proficiency and distant ones near 2,200. Guided hours also under-count production: speaking practice is the rung-clip that no table prices.
Worked Example
- Estimate your cumulative guided hours.
- Enter the weekly hours you sustain.
- Read the band and the next threshold.
- Price the gap in weeks.
Defaults: 250 hours at 5 a week → A2, 100.000000 hours to B1, 20.000000 weeks. Drive to 600 → B2's window with C1 a 100-hour climb. Drive to 1,100 → the C2 window, the top of the ladder.

Methodology & Editorial Standards
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.
This engine was reconciled against an independent reference implementation and hand-verified for the worked example above before release. Our full five-stage review process is published on the About Us page.

Language Level Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How many hours does each CEFR level take?
Cambridge's estimates for English: A2 near 180–200 guided hours, B1 at 350–400, B2 at 500–600, C1 at 700–800, and C2 at 1,000–1,200, cumulative from absolute beginner. The A1 stage sits near 90–100. Treat them as a map, not a meter — intensity and language pair move the milestones.
What counts as a guided hour?
Structured learning with instruction — lessons, tutored sessions, guided coursework. Self-study helps but is not what the tables count, which is why real learners often move faster than their guided figure suggests. Log the guided lane honestly and treat the rest as margin.
Why does C2 cost more than everything below it?
The ladder steepens: the C1–C2 stretch is 300–400 hours against roughly 150–200 per rung in the middle. Late-stage gains come from nuance — register, idiom, precision — and nuance resists shortcuts more than vocabulary ever did.
Is B2 really the threshold that matters?
For universities and most employers, yes — B2 is the band admissions offices and international job posts usually name, the level where conversations stop being survival and start being work. It is why the page prices the rung below it as carefully as the top.
Do these hours apply to every language?
The table is English-classroom centered. The US Foreign Service Institute ranks pairs: languages close to English reach professional working proficiency near 600–750 class hours, while distant ones — Japanese, Korean, Mandarin, Arabic — sit near 2,200. Same ladder, very different price tags.
I study 10 hours a week — when is B1 realistic?
From 250 guided hours, the 100-hour gap to B1 closes in 10.000000 weeks at that rate. The weeks card is the honest scheduler: divide the gap by the rate you actually keep, not the one January promised.
Can I skip rungs?
Learners do — intensive immersion compresses the early rungs — but the hours do not vanish; they condense. The bands describe ability, and ability is cumulative: the reading you skipped at A2 returns as the gap you feel at B2.
How do I turn a band claim into evidence?
Sit the exam — IELTS and TOEFL map scores onto the CEFR scale and are the claims institutions recognize. The IELTS and TOEFL pages price those scores; this page prices the road to being ready for them.
