Course Load Calculator
Recommended credit hours from work schedule and commitments.
About this calculator
A realistic credit load starts from the 168 hours in a week and subtracts everything that isn't academic before deciding how much study time is actually left. This calculator adds up Work Hours per Week, Commute Hours per Week, Family Obligations (hrs/week), Sleep Hours per Night times 7, a fixed 10 hours for basic personal care (eating, hygiene), and Extracurricular Hours/Week into total fixed commitments, then subtracts that from 168 to get Available Hours/Week for Academics. Each credit hour is assumed to require 1 hour of class time plus Study Hours per Credit of outside study — the Carnegie Unit standard recommends 2-3 hours of outside study per credit hour, which is why the default sits at 2.5.
Dividing Available Hours/Week for Academics by that per-credit time gives Maximum Feasible Credits (capped at 21, since course overloads beyond that are rarely permitted without special approval), and Recommended Credit Hours mirrors that figure. Full-Time Load reports the standard academic definition of full-time enrollment (up to 15 credits) if your schedule can support it, and Stress Level (0-10) is a simple utilization indicator: how much of your Available Hours/Week for Academics gets consumed by studying at your maximum feasible load, scaled to a 0-10 range. What this calculator does not know: how demanding your specific courses actually are beyond the flat per-credit study assumption, whether your job schedule has slack for cramming during exam weeks, or how sustainable a given stress level is for you personally over a full semester — treat the output as a starting point for a conversation with an academic advisor, not a binding schedule.

Frequently Asked Questions
Why does raising Sleep Hours per Night lower Recommended Credit Hours so noticeably?
Because Sleep Hours per Night is multiplied by 7 to get weekly sleep hours before it's subtracted from your 168-hour week, so a change to nightly sleep has a 7x-larger weekly effect than a change of the same size to a once-a-week commitment like Family Obligations. Protecting adequate sleep is deliberately weighted this heavily in the underlying math — sleep is a daily, non-negotiable commitment in a way that most other categories aren't, and this calculator treats it that way rather than as a discretionary line item you could simply trim.
What happens if Available Hours/Week for Academics comes out very low or negative?
Available Hours/Week for Academics is never allowed to go below zero — the calculator clamps it there instead, which means Maximum Feasible Credits and Recommended Credit Hours both drop to zero once your fixed commitments (work, commute, family, sleep, personal care, and extracurriculars) already add up to more than the full 168-hour week. That result is a signal to reduce a fixed commitment — most realistically work hours or extracurricular time — before adding any course load at all, not a calculator error.
Does increasing Study Hours per Credit always lower Recommended Credit Hours?
Yes — Study Hours per Credit adds directly to the 1 hour of class time assumed per credit, so a higher value raises the total hours each credit consumes, which lowers how many credits fit into your fixed Available Hours/Week for Academics. Setting this higher (closer to 3, matching demanding STEM or writing-intensive courses) produces a more conservative, sustainable credit recommendation than the Carnegie Unit's minimum-standard 2.0-2.5 range.
What does Stress Level (0-10) actually measure?
It's the ratio of study hours needed at Maximum Feasible Credits to your total Available Hours/Week for Academics, scaled to a 0-10 range — a value near 10 means you'd be using nearly all of your available academic time studying at your maximum load, leaving little slack for unexpected demands. It's not a measure of how hard your specific courses are, only how tightly your schedule is packed relative to the time you've told the calculator you have available.
