How do I calculate my JAMB aggregate score?
Divide your JAMB UTME score by 8 and your Post-UTME score by 2, then add the two results together for an aggregate out of 100. Example: a UTME score of 280 and a Post-UTME score of 70 give 280/8 + 70/2 = 35 + 35 = 70.0.
Steps to calculate your JAMB aggregate score
- Find your JAMB UTME score, which is out of 400.
- Find your Post-UTME (post-University Tertiary Matriculation Examination) score from your chosen institution, which is typically out of 100.
- Divide your UTME score by 8 to convert it to a 50-point scale.
- Divide your Post-UTME score by 2 to convert it to a 50-point scale.
- Add the two converted scores together to get your aggregate score out of 100.
Formula
Aggregate = (JAMB UTME score / 8) + (Post-UTME score / 2), out of 100
- JAMB UTME score = your Unified Tertiary Matriculation Examination score, 0-400
- Post-UTME score = your chosen university's post-UTME screening score, typically 0-100
Quick JAMB aggregate answers
JAMB 280 plus Post-UTME 70 — what's the aggregate?
280 ÷ 8 + 70 ÷ 2 = 35 + 35 = 70.0.
JAMB 250 plus Post-UTME 60 — what's the aggregate?
250 ÷ 8 + 60 ÷ 2 = 31.25 + 30 = 61.3.
What's the maximum possible JAMB aggregate?
400 ÷ 8 + 100 ÷ 2 = 50 + 50 = 100.0, the maximum.
JAMB 180 plus Post-UTME 55 — what's the aggregate?
180 ÷ 8 + 55 ÷ 2 = 22.5 + 27.5 = 50.0.
JAMB 320 plus Post-UTME 80 — what's the aggregate?
320 ÷ 8 + 80 ÷ 2 = 40 + 40 = 80.0.
Why is JAMB divided by 8 and Post-UTME by 2?
It converts JAMB's 400-point scale and Post-UTME's 100-point scale to matching 50-point scales, so the two can combine into one 100-point aggregate.
Does a 0 JAMB score with a 0 Post-UTME score give 0?
Yes — an aggregate of 0.0.
Does JAMB or Post-UTME weigh more per raw point?
Post-UTME does — each raw point there is divided by 2 instead of 8, so a 1-point gain in Post-UTME moves the aggregate more than a 1-point gain in JAMB.
Example aggregate calculations
| UTME score | Post-UTME score | Aggregate (out of 100) |
|---|
| 280 | 70 | 70.0 |
| 400 | 100 | 100.0 |
| 0 | 0 | 0.0 |
| 180 | 55 | 50.0 |
| 320 | 80 | 80.0 |
Frequently asked questions
Does every Nigerian university use this exact formula?
No. This is a commonly cited general formula, but universities set their own aggregate weighting between JAMB, Post-UTME and sometimes O'Level results, and their own cut-off marks per course. Always check your specific institution's admission portal or JAMB CAPS guidance for the formula that applies to you.
What is a good JAMB aggregate score?
There is no single answer — competitive courses like Medicine at top universities often require aggregates well above 70, while less competitive courses may admit lower scores. The cut-off depends on the course, the university, and the number of applicants that year.
Is Post-UTME the same as JAMB?
No. JAMB (UTME) is the national entrance exam administered once per admission cycle. Post-UTME is a separate screening exercise conducted by individual universities after JAMB, using their own test, screening, or a combination of JAMB score and O'Level results.
Can my O'Level results affect my aggregate?
Some universities incorporate O'Level grades into the aggregate formula in addition to JAMB and Post-UTME scores. This calculator only covers the widely used two-component formula; check your target institution if O'Level results are part of their calculation.
This calculator uses a general, widely cited aggregate formula. It is not an official JAMB or university tool, does not reflect course-specific or institution-specific weighting, and does not include O'Level results some universities factor in. Confirm the exact formula and cut-off mark with your target university before relying on this result for admission decisions.
