About Lecture Hours Requirement Calculator

Contact hours follow from credits: one credit typically means one lecture hour a week for the semester. The attendance rule then converts into a concrete number of hours you can miss, which is far more useful than a percentage when planning around commitments.

Formulas

Total lecture hours

Total = Credits x Contact hours per credit x Semester weeks

Hours you can miss

Missable = Total hours x (1 - Minimum attendance %)

Worked example

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 1 decimal place, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Are laboratory hours counted the same way?

Usually not. Labs and studios commonly count two or three contact hours per credit, so check the scheme of instruction.

What happens below the attendance threshold?

Most institutions bar the student from the end-of-semester examination, with condonation only on documented medical grounds.
