About Study Time per Credit
Applies the standard expectation of two hours of independent study for every credit hour, adds scheduled contact time, and then adds paid work to show the real weekly commitment - the number that reveals whether a course load is sustainable alongside a job.
Formulas

Assumptions and limits
- The result is derived only from the 5 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
Is two hours per credit hour realistic?
It is the standard institutional expectation and roughly right for a demanding course. Quantitative and lab-heavy subjects often need three; some electives need one.
When does the total become unsustainable?
Above roughly 55-60 hours a week of combined study and work, attrition and grade decline rise sharply. Fifteen credits plus twenty work hours already sits near that line.
