What the Credit Hours Calculator does
Credit hours drive almost everything administrative about a degree: enrolment status, tuition, workload and time to graduation. Dividing the credits you still need by the load you can sustain each term gives a realistic finish date, and the two-hours-per-credit rule turns that load into actual weekly hours.
Formula
Progress = (Earned + This term) ÷ Required × 100Terms remaining = ⌈Credits remaining ÷ Credits per term⌉Weekly study = Credits × Study ratioTuition = Credits × Cost per credit

How to use it
- Choose Currency.
- Enter Credits this term and Credits required for the degree.
- Optionally add Credits already earned, Cost per credit hour and Full-time minimum.
- Select Calculate.
Worked example
15 credits this term, 60 already earned, 120 needed, at $400 per credit.
- This term
- 15
- Earned
- 60
- Required
- 120
- Cost
- $400
Full time at 15 credits. 45 credits remain after this term, so 3 more terms — 1.5 years. Tuition this term is $6,000, with $18,000 still to come.
Reading the result
- The load-versus-timeline table shows the concrete trade-off between credits per term and years to graduate — useful for judging whether bumping from 12 to 15 credits, or adding a summer term, materially shortens the finish date.
Assumptions and limitations
- "Terms remaining" assumes the same credit load every future term as entered for this one — a student planning to take fewer or more credits later sees a different real timeline than this straight-line projection.
- Full-time status is checked against a single entered minimum — the notes flag that financial aid, visa and insurance rules can each impose their own separate threshold, so passing this one check does not guarantee passing all of them.
Common mistakes
- Treating "estimated time to finish" as a fixed prediction rather than a projection at the current pace — a single lighter term changes the real finish date in a way this figure does not reflect until it is re-run.
Frequently asked questions
How many credits is full time?
Twelve for most US undergraduates, though nine is common for graduate study. Financial aid and visa rules sometimes impose different minimums, so confirm each separately.
How long should a credit hour take each week?
One hour in class plus two to three hours of independent study. A 15 credit load is therefore a 45 to 60 hour week — genuinely full-time work.
