How to calculate retention rate (IPEDS)

The IPEDS retention rate is the percentage of an institution's first-time, degree- or certificate-seeking undergraduates from one fall who are still enrolled (or, at less-than-four-year institutions, have completed their program) the following fall. It is reported separately for full-time and part-time first-time students and is calculated against an adjusted cohort.

Formula

Retention rate (%) = (cohort students still enrolled or completed the next fall / adjusted fall cohort) x 100, where adjusted cohort = original cohort - allowable exclusions + inclusions

Variables

Original cohort: First-time, full-time (or part-time) degree- or certificate-seeking undergraduates who entered the institution the previous fall.
Allowable exclusions: Cohort students who left for an IPEDS-permitted reason: death, total and permanent disability, military service, federal foreign aid service (e.g., Peace Corps), or official church mission.
Inclusions: Students added back into the cohort during data review (for example, students who should have been counted as first-time).
Adjusted cohort: Original cohort minus allowable exclusions plus inclusions; the denominator of the retention rate.
Still enrolled / completed: Cohort students re-enrolled the following fall; at less-than-four-year institutions, this also includes those who completed their program.

How to calculate it

1Define the cohort: count all first-time, degree- or certificate-seeking undergraduates who entered the previous fall, separated into full-time and part-time groups.
2Identify allowable exclusions: subtract cohort members who died, became totally and permanently disabled, or left for military service, federal foreign aid service, or an official church mission.
3Apply any inclusions to arrive at the adjusted cohort (original cohort minus exclusions plus inclusions).
4Count how many adjusted-cohort students are enrolled again in the current fall; at less-than-four-year institutions, also count those who completed their program.
5Divide the still-enrolled or completed count by the adjusted cohort and multiply by 100.
6Report the full-time and part-time retention rates separately in the IPEDS Fall Enrollment (EF) component.

Worked example

A four-year university enrolls 1,000 first-time, full-time bachelor’s degree-seeking students in a fall term. Over the next year, 5 students leave for allowable reasons (2 die, 3 enter active military duty), so the adjusted cohort is 1,000 - 5 = 995. The following fall, 850 of those students are enrolled again. Retention rate = (850 / 995) x 100 = 85.4 percent.

FTE calculation: headcount vs FTE vs FTTE

Full-time equivalent (FTE) enrollment converts a mix of full-time and part-time students into a single number representing how many full-time students that activity equals. Headcount is the unduplicated count of individual students (each person counts as one, regardless of load), FTE weights students by their actual course load, and FTTE (full-time tuition equivalent) weights them by tuition-generating credit hours.

Formula

12-Month FTE = (undergraduate credit hours / UG divisor) + (graduate credit hours / grad divisor) + (clock hours / 900). Divisors: 30 UG / 24 grad for semester, trimester, 4-1-4; 45 UG / 36 grad for quarter. Fall FTE (estimated) = full-time headcount + (part-time headcount x level/control factor), e.g. .403543 part-time UG, .361702 part-time grad, .600000 part-time first-professional at public 4-year institutions.

Variables

UG / grad credit hours: Total instructional activity (credit hours) over the 12-month reporting period: each course’s credit value times its for-credit enrollment, summed.
UG divisor: Credit hours equal to one undergraduate FTE: 30 for semester/trimester/4-1-4, 45 for quarter calendars.
Grad divisor: Credit hours equal to one graduate FTE: 24 for semester/trimester/4-1-4, 36 for quarter calendars.
Clock hours: Total clock-hour instructional activity, divided by 900 to yield one FTE.
Conversion factor: IPEDS multiplier applied to part-time headcount, specific to student level and institutional control (e.g., .403543 part-time UG and .361702 part-time graduate at public 4-year institutions).

How to calculate it

1Decide which FTE you need: the IPEDS 12-Month Enrollment (E12) FTE from instructional activity, or the IPEDS Fall Enrollment estimated FTE. They use different methods and are not interchangeable.
2For the 12-month instructional-activity FTE, sum all credit hours (each course’s credit value times its for-credit enrollment), separated into undergraduate and graduate (and clock hours if applicable).
3Pick the divisors that match your academic calendar: 30 UG / 24 grad for semester, trimester, or 4-1-4; 45 UG / 36 grad for quarter; 900 for clock hours.
4Divide undergraduate credit hours by the UG divisor and graduate credit hours by the grad divisor, then add the results (plus clock hours / 900) for total 12-month FTE.
5For the Fall Enrollment estimated FTE instead, take the full-time headcount as is, then multiply the part-time headcount by the IPEDS conversion factor for that level and control.
6Add the full-time headcount to the converted part-time figure for estimated fall FTE. For a quick internal estimate, many IR offices instead divide total credit hours by 15 (undergraduate) or 12 (graduate).

Worked example

A public 4-year university on a semester calendar reports 300,000 undergraduate and 48,000 graduate credit hours over the 12-month period. 12-month FTE = 300,000 / 30 + 48,000 / 24 = 10,000 + 2,000 = 12,000 FTE. Separately, its fall snapshot shows 8,000 full-time and 2,000 part-time undergraduates. Estimated fall undergraduate FTE = 8,000 + (2,000 x .403543) = 8,807 FTE, even though the headcount is 10,000 students.

IPEDS reporting deadlines 2025-26 for keyholders

IPEDS reporting deadlines are the fixed dates by which an institution's keyholder must submit and lock each federal survey component in the IPEDS Data Collection System. For 2025-26, NCES groups the components into three collection periods with keyholder lock dates of October 15, 2025 (Fall), February 4, 2026 (Winter), and April 1, 2026 (Spring). These dates are identical for every Title IV institution.

Formula

Coordinator close = keyholder close + 14 days. Days remaining = deadline date - today, where the keyholder deadline is the close date of the collection period that contains the component you are reporting.

Variables

Fall close: Keyholder October 15, 2025 / coordinator October 29, 2025. Components: IC, Cost I, Completions, 12-Month Enrollment.
Winter close: Keyholder February 4, 2026 / coordinator February 18, 2026. Components: Cost II, Student Financial Aid, Graduation Rates, GR200, Admissions, Outcome Measures.
Spring close: Keyholder April 1, 2026 / coordinator April 15, 2026. Components: Fall Enrollment, Finance, Human Resources.
Coordinator offset: State or system coordinators always get exactly 14 days beyond the institutional keyholder date.

How to calculate it

1Identify every survey component your institution must report this cycle (for example Completions, Student Financial Aid, Fall Enrollment).
2Map each component to its collection period: Fall covers IC, Cost I, Completions, and 12-Month Enrollment; Winter covers Cost II, Student Financial Aid, Graduation Rates, GR200, Admissions, and Outcome Measures; Spring covers Fall Enrollment, Finance, and Human Resources.
3Look up the keyholder close date for that period: October 15, 2025, February 4, 2026, or April 1, 2026.
4If you are a state or system coordinator rather than an institutional keyholder, add 14 days (October 29, 2025; February 18, 2026; April 15, 2026).
5Subtract today from the deadline for days remaining, then enter, import, and fully lock all data before 11:59 p.m. on the keyholder close date. Registration opens August 6, 2025 (register by August 27), the Fall window opens September 3, 2025, and the Winter and Spring windows open December 3, 2025.

Worked example

You are the keyholder reporting Completions, which sits in the Fall collection. Its keyholder close is October 15, 2025, so the matching coordinator close is October 15 + 14 days = October 29, 2025. If today is September 3, 2025 (the day the Fall window opens), days remaining to the keyholder lock = 42. You must lock the data before 11:59 p.m. on October 15, 2025; missing a deadline can trigger non-compliance and jeopardize Title IV eligibility.

Graduation rate (150% time) and cohort default rate

The IPEDS graduation rate (GR150) is the share of first-time, full-time degree- or certificate-seeking students who complete their program at the starting institution within 150% of normal time (six years for a four-year bachelor's degree). The cohort default rate (CDR) is the share of a school's federal student loan borrowers who enter repayment in a fiscal year and default within the three-year monitoring window, published annually by Federal Student Aid.

Formula

GR150 = (completers within 150% of normal time at the starting institution / adjusted cohort of first-time full-time degree/certificate-seeking students) x 100. CDR (3-year) = (borrowers who entered repayment in a fiscal year and defaulted on or before the end of the second following fiscal year / borrowers who entered repayment that fiscal year) x 100.

Variables

Completers within 150% time: Cohort students who earned the credential they sought, at the same institution, within 1.5 times the program’s normal length.
Adjusted cohort: First-time, full-time degree/certificate-seeking students minus allowable exclusions (death, total and permanent disability, military or foreign-aid service, official church mission).
Normal time: The standard published program length (4 years for a bachelor’s degree, so the 150% window is 6 years; GR200 uses 200%, an 8-year window).
Borrowers entering repayment: Federal Direct Loan (and legacy FFEL) borrowers whose repayment period began during the cohort fiscal year (October 1 to September 30); the CDR denominator.
Borrowers who defaulted: Cohort borrowers who defaulted on or before the end of the second fiscal year after entering repayment; the CDR numerator.

How to calculate it

1For GR150, identify the cohort: all first-time, full-time degree- or certificate-seeking undergraduates who entered in the reference fall.
2Subtract allowable exclusions to get the adjusted cohort (the denominator).
3Count students who completed at the same institution within 150% of normal program time (six years for a bachelor’s degree).
4Divide completers by the adjusted cohort and multiply by 100 for GR150. (GR200 repeats the count at 200% of normal time.)
5For CDR, identify all borrowers who entered repayment during the cohort fiscal year (the denominator).
6Count how many defaulted before the end of the second following fiscal year (the numerator), divide, and multiply by 100 for the three-year CDR.

Worked example

Graduation rate: a college’s adjusted cohort is 980 first-time, full-time bachelor’s-seeking students; by the end of year six, 540 graduated from that same college. GR150 = 540 / 980 x 100 = 55.1 percent. Cohort default rate: of 500 borrowers who entered repayment in a fiscal year, 15 defaulted within the three-year window. CDR = 15 / 500 x 100 = 3.0 percent. Note that recent CDRs are unusually low across the sector, because the COVID-19 payment pause (effective March 13, 2020) stopped Department-held loans from entering default.

Net price calculator requirement and survey response rate

Net price is the total cost of attendance minus grant and scholarship aid. The Higher Education Opportunity Act of 2008 requires every Title IV institution that enrolls full-time, first-time degree- or certificate-seeking undergraduates to post a net price calculator on its website, a mandate effective October 29, 2011. A survey response rate is the share of an eligible sample that returns a usable response, calculated as completed responses divided by the eligible sample, times 100.

Formula

Net price = total cost of attendance - (grant aid + scholarship aid). IPEDS average net price = total cost of attendance - average grant and scholarship aid, for full-time first-time degree/certificate-seeking undergraduates who received aid. Survey response rate (%) = (completed responses / eligible sample) x 100.

Variables

Cost of attendance (COA): Published tuition and required fees, plus books and supplies, plus the weighted average of room and board and other expenses for the academic year.
Grant and scholarship aid: Gift aid from federal, state/local, or institutional sources that does not have to be repaid; loans and work-study are excluded.
Eligible aid cohort: Full-time, first-time degree/certificate-seeking undergraduates awarded grant or scholarship aid; the population IPEDS uses for average net price.
Eligible sample: Cases in a drawn survey sample that qualify to respond after removing ineligibles; the denominator of the response rate.

How to calculate it

1Confirm the institution participates in Title IV and enrolls full-time, first-time degree/certificate-seeking undergraduates; if so, the HEOA net price calculator is required.
2Determine total cost of attendance: add published tuition and required fees, books and supplies, and the weighted average for room and board and other expenses.
3Sum grant and scholarship aid for the student (or, for IPEDS, the average for the eligible aid-receiving cohort); exclude all loans.
4Subtract grant and scholarship aid from total cost of attendance to get net price.
5For a survey response rate, define the eligible sample by removing ineligible or out-of-scope cases.
6Count completed responses that meet your completeness threshold, divide by the eligible sample, and multiply by 100; report the response rate separately from the completion rate.

Worked example

Net price: a full-time first-time student has a total cost of attendance of $28,000 and receives $11,500 in grants and scholarships. Net price = 28,000 - 11,500 = $16,500. Survey response rate: an IR office emails a survey to 1,200 students; after removing 50 invalid addresses the eligible sample is 1,150, and 322 submit complete responses. Response rate = (322 / 1,150) x 100 = 28.0 percent.

Frequently asked

IR metric questions, answered

What is the difference between retention and persistence?+

Retention measures whether a student stays at the same institution from one fall to the next, which is what IPEDS reports. Persistence measures whether a student remains enrolled anywhere in higher education, including after transferring. A student who transfers out lowers the first institution’s retention rate but still counts as persisting in the broader system.

How does retention differ from graduation rate?+

Retention is a year-to-year measure of continued enrollment for first-time students. Graduation rate is a longer-term outcome measuring the share of a cohort that completes a credential within a set time (typically 150 percent of normal program length). Retention is an early signal; graduation is the final outcome.

What counts as first-time, full-time for the IPEDS cohort?+

A first-time student is an entering undergraduate who has never previously attended any postsecondary institution (credits earned while still in high school do not disqualify them). Full-time generally means enrolled for 12 or more semester credit hours. The student must also be degree- or certificate-seeking to enter the cohort, which is the basis for IPEDS retention and graduation-rate reporting.

What is the difference between headcount and FTE?+

Headcount is the unduplicated number of individual students: a part-time and a full-time student each count as one. FTE weights students by course load, so two half-time students count as roughly one FTE. Headcount is best for counting people; FTE is best for budgeting, workload, and comparing institutions on different calendars.

What is FTTE, and how is it different from FTE?+

FTTE is full-time tuition equivalent. It standardizes enrollment by tuition-generating credit hours rather than total instructional load, so students whose combined credits generate the tuition of one full-time student equal 1.0 FTTE. FTE reflects educational workload; FTTE reflects revenue, so the two figures can differ when some hours are excluded from tuition.

What is an IPEDS keyholder?+

A keyholder is the person at a postsecondary institution officially designated to enter, verify, and lock that institution’s data in the IPEDS Data Collection System. The keyholder is accountable for meeting each submission deadline, and keyholder status is tied to the institution’s Title IV participation.

What is the difference between the keyholder deadline and the coordinator deadline?+

The keyholder deadline is the date an institution must submit and lock its data. The coordinator deadline applies to a state or system IPEDS coordinator reviewing submissions for a group of institutions, and it always falls 14 days after the keyholder date (October 29, 2025; February 18, 2026; April 15, 2026). Institutional keyholders must always meet the earlier keyholder deadline.

How is the 150% time window set for different programs?+

It is 150 percent of the program’s published normal length. For a four-year bachelor’s degree the window is six years; for a two-year associate degree it is three years; for a one-year certificate it is eighteen months. GR200 uses 200 percent of normal time instead, for example eight years for a bachelor’s degree.

Why are recent cohort default rates so low?+

The COVID-19 payment pause that began March 13, 2020 placed most federally held student loans in administrative forbearance, and no borrowers with Department-held loans entered default during that period. This suppressed recent cohort default rates, so they understate actual borrower repayment difficulty.

When did the net price calculator requirement take effect?+

The Higher Education Opportunity Act of 2008 established the mandate, effective October 29, 2011. As of that date, every Title IV institution that enrolls full-time, first-time degree- or certificate-seeking undergraduates must post a net price calculator on its website.

What is the difference between a response rate and a completion rate?+

A response rate is completed responses divided by the full eligible sample, measuring overall participation. A completion rate is the share of people who started the survey and finished it (completes divided by starts). A survey can have a low response rate but a high completion rate.

Does net price include loans?+

No. Net price subtracts only grant and scholarship aid (gift aid that is not repaid) from total cost of attendance. Loans and work-study are not deducted, because they are financing methods rather than reductions in price.
