Teaching Hours Allocation Calculator

Work out teaching hours allocation instantly with clear inputs, formula shown and shareable results.

About Teaching Hours Allocation Calculator

Teaching load is contact hours multiplied by a preparation ratio, plus marking. Eight contact hours at 1.5 preparation is twenty hours a week, and 120 students at 25 minutes each is fifty hours per assessment round. Across a twelve week term with two assessments that is 340 hours - 42.5% of a term's working time.

Formulas

Weekly teaching

hours = contact hours x (1 + preparation ratio)

Marking

hours = students x minutes per student / 60

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 2 decimal places, 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

What preparation ratio is realistic?

Two to three hours per contact hour for a new module, falling to about one for a course taught repeatedly. Institutional models often assume too little.

Why is marking so often underestimated?

Because it scales with student numbers rather than contact hours, so a large cohort can make marking the single largest component.
