Student Dropout Rate

Risk KPI complementary to retention. Definitions of dropout vs transfer vs stop-out vary by institution.

Dropout % = students who left ÷ enrolled/cohort × 100.

Tip: Keep “Dropouts” and “Enrolled / Cohort” on the same basis (units, period, and definition) before you calculate.

Dropout rate estimates the share of students who left without completing in the measured window.

Enter dropouts and enrolled (or cohort) count for the same definition.

Understanding Student Dropout Rate

How we calculate. Dropout % = students who left ÷ enrolled/cohort × 100. See our methodology and accuracy policy .

Real-world scenario: A typical Student Dropout Rate case uses dropouts 90 and enrolled / cohort 1500. Enter the same figures below to reproduce the worked path.

What is Student Dropout Rate?

Risk KPI complementary to retention. Definitions of dropout vs transfer vs stop-out vary by institution.

  • Define dropout clearly
  • Same base population
  • Transfers may be excluded

The Formula

Student Dropout Rate
Dropout % = (Dropouts ÷ Enrolled) × 100

Worked Example

Scenario: 90 dropouts out of 1,500 enrolled.
Step 1: Dropouts = 90
Step 2: Enrolled = 1500
Step 3: Rate = (90 ÷ 1500) × 100 = 6%
Answer: Student dropout rate is 6%.

Common Use Cases

  • Early-alert programs: risk heatmaps
  • Program health: leave patterns
  • Grant reporting: attrition measures

Pro Tips

  • Tag reasons when possible
  • Separate academic vs financial exits
  • Pair with retention

Limitations: Student Dropout Rate results are educational institutional planning aids—not accreditation determinations or financial-aid advice. Confirm measure specs with your registrar and IR office.

Common mistakes

  • Swapping part and whole: The denominator must be the full total, not a subset.
  • Rounding too early: Carry extra decimal places through multi-step work before rounding the final percent.
  • Mixing percent and decimal forms: Enter rates in the format the calculator labels expect.
