Teacher Time Savings ROI Calculator

Faculty at most institutions spend 15-20 hours per week on grading, rubric application, and providing written feedback on student work. This calculator helps IT administrators and academic leadership quantify the concrete time and cost savings that AI-assisted grading delivers per teacher, per department, and across the entire institution. It factors in your institution's specific class sizes, assignment frequency, and current grading workflows to produce a personalized estimate. The results help you build a data-driven business case for adopting automated grading tools, showing both the immediate time recovery for educators and the long-term budget impact of reallocating those hours toward instruction, research, or student mentoring.

Calculation Methodology

The calculator uses three inputs: number of teachers, average hours spent grading per week, and average hourly compensation (including benefits). It applies a conservative 75% automation rate based on benchmarks from institutions using AI-assisted grading for objective assessments (multiple choice, short answer, code review) and a 40% rate for subjective assessments (essays, projects). Weekly hours saved are multiplied by 40 teaching weeks per year, then multiplied by the loaded hourly rate to produce an annual dollar savings figure. The 3-year projection applies a 5% annual increase in compensation costs. These benchmarks are drawn from published case studies at institutions with 500-5,000 students using AI grading tools.
