See how many credits a minor genuinely adds to your schedule after overlap — and what that costs in time and money.
The credits a minor requires aren't the same as the credits it actually adds — any course that also counts toward your major, a general education requirement, or a free elective you'd take anyway is not really an extra cost. This calculator subtracts that overlap to find your genuinely extra credit count, then checks whether your normal "spare capacity" per semester (room in your schedule beyond your usual course load) can absorb them without delaying graduation. If it can't, it estimates the extra semester and cost.
A business minor requires 18 credits. Two of its courses also satisfy your general education requirements, so 6 credits overlap and only 12 are really extra. If your normal schedule leaves room for 3 extra credits a semester and you have four semesters left, you can absorb all 12 without adding time. You still pay for those 12 credits if your school charges per credit ($5,400 at $450 a credit), but you don't pay for an extra semester of housing and food. Under flat-rate tuition they may cost nothing at all.
Now change one number: you have two semesters left. You can absorb 6 of the 12 credits, and the other 6 push you into an extra semester. Now the cost is no longer just the credits: it is another term of rent, food and fees, plus a semester of earnings you don't make. That is the case the calculator flags.

| Situation | Extra cr. | Adds time? |
|---|---|---|
| Big overlap, early | 6–9 | Usually no |
| Small overlap, early | 15–18 | Sometimes |
| Small overlap, late | 15–18 | Often yes |
Minor credits count as attempted credits for Satisfactory Academic Progress, including the 150% maximum timeframe, and an extra semester uses another 50% of your Pell lifetime eligibility if you receive Pell. Most students stay well inside those limits, but if you have also changed majors or lost credits in a transfer, check your room with the SAP calculator before adding a minor late.
Do minors always cost extra money? Not always. If most of the minor's required courses overlap with electives or general education requirements you'd take anyway, a minor can add close to zero extra cost. The cost climbs when the minor requires courses that don't count toward anything else you're already taking.
How many credits does a typical minor require? Most minors require 15 to 24 credits, roughly half of what a major requires. Check your specific program's requirements rather than assuming a standard number.
Is a minor worth it if it doesn't add any extra time? If a minor fits entirely within your existing schedule and doesn't delay graduation, it's close to a free addition to your resume — the main cost becomes the opportunity cost of not using those elective credits for something else.
Should I pick a minor that's closely related to my major, or something completely different? A closely related minor tends to be easier to fit into your schedule since it may share prerequisites. An unrelated minor can round out your profile but is more likely to require dedicated extra credits with less overlap. Neither is objectively better — it depends on your goals.
