What this result does not account for
- Cumulative fraction; semester-by-semester SAP variants exist
- Institutional GPA floors may exceed the federal 2.0
In short: Federal aid reads three numbers: completion rate (earned ÷ attempted, floor 67%), degree credits remaining, and the 150% timeframe cap. Attempt 45 credits and earn 30 — withdrawals and fails count attempted but not earned — and the completion rate is 66.666667%: below the floor, a financial-aid warning zone. Ninety credits remain of the 120 the degree asks, and the cap allows 180 attempted — 135 of headroom spent. Pace is the SAP measure GPA cannot rescue.
Formula
completion = earned ÷ attempted ··· cap = 150% of degree credits
Satisfactory Academic Progress (SAP) is the federal gate on aid, and its quantitative arm is pace: earn at least two-thirds of everything attempted, cumulatively. Withdrawals, fails and incompletes all count as attempted but not earned; repeats count both sides; transfer credits count on both. Alongside pace sits the 150% maximum timeframe — a 120-credit degree must be finished within 180 attempted credits, whatever the GPA — and the qualitative arm asks a cumulative 2.0.
Worked Example
- Pull attempted and earned hours off the transcript.
- Enter the degree's published credit length.
- Read the completion rate against the 67% floor.
- Check the 150% cap headroom before enrolling.
Defaults: 45 attempted, 30 earned, 120-credit degree → 66.666667% completion — a single credit short of the floor (31 earned reads 68.888889% and passes); 90 credits to go, 135 of the 180-credit cap unused. The gap between attempted and earned is the whole SAP story: W, F and I live on one side only.

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.

Credit Hour Calculator — 8 Expert FAQs
8 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is the 67% completion rule?
The federal Satisfactory Academic Progress pace requirement: to keep aid, you must earn at least two-thirds of all credits attempted, measured cumulatively. Attempt 45 and earn 30 and you sit at 66.666667% — one credit short. It is a fraction, not a semester rule; every W, F and I in your history is inside it.
Do withdrawn courses count?
In the attempt column only. A W is attempted but not earned — it skips the GPA but lands squarely on pace. Incompletes behave the same until resolved, and a fail attempts without earning. This is why pace is the SAP measure GPA cannot rescue: the damage sits outside the grade-point arithmetic.
What is the 150% maximum timeframe?
Aid ends once attempted credits exceed 150% of the degree's published length — 180 attempted for a 120-credit bachelor's. Transfers count toward the cap even when they do not count toward the degree, which is why changing majors late is expensive twice.
How many credits make me a full-time student?
Twelve or more per semester for undergraduates (nine for most graduate programs). Full-time status drives aid amounts, insurance and deferments — but note that 12 a semester finishes a 120-credit degree in ten semesters, not the eight that 15 a semester delivers.
What is a credit hour, really?
A convention: roughly one hour of class plus two hours of outside work per week for a semester — the Carnegie-unit descendant. A 15-credit load is a 45-hour work week when taken honestly, which is the number to quote anyone treating 18 credits as a light semester.
Can one semester restore my completion rate?
Often yes — pace is cumulative, so a clean term moves the fraction fast. From 30 of 45 (66.666667%), earning 15 of 15 lands 45 of 60 = 75.000000%. The same arithmetic says a failed comeback digs deeper: the fraction remembers everything.
Do repeated courses count twice?
They count as attempted (again) and, on a pass, earned; only the last grade enters most GPA calculations. Repeats are therefore pace-expensive but GPA-cheap — the right tool when the first grade was an F, a waste of headroom when it was a C.
How does this interact with my GPA?
SAP has two arms: the 67% pace floor and a cumulative 2.0 GPA, plus the 150% timeframe. They fail independently — a 3.4 GPA with a 60% completion rate loses aid exactly as surely as a 2.0 with perfect pace. The transcript keeps the credits; this page keeps the fraction.
