If you are applying to a Nigerian university, knowing your JAMB score is only part of the admission process. Many institutions also conduct Post-UTME screening and calculate an aggregate score from multiple admission components.
A common question is:
How do I calculate my JAMB and Post-UTME aggregate score?
The answer depends on your institution.
There is no single aggregate formula used by every Nigerian university. JAMB’s admission system allows institutions to define admission criteria for individual programmes, including minimum UTME, Post-UTME and aggregate scores.
This guide explains the most common calculation methods and how to estimate your admission score correctly.

How Is the JAMB Score Calculated?
The Unified Tertiary Matriculation Examination (UTME) has a maximum total score of:
400
So if your JAMB result is:
280/400
your percentage equivalent is:
280 ÷ 400 × 100 = 70%
Similarly:
| JAMB Score | Percentage Equivalent |
|---|---|
| 200 | 50% |
| 220 | 55% |
| 240 | 60% |
| 260 | 65% |
| 280 | 70% |
| 300 | 75% |
| 320 | 80% |
However, your university may not simply convert the score to 100%. It may assign JAMB a particular weight in its admission formula.
What Is an Aggregate Score?
An aggregate score is the combined score an institution uses to rank or assess candidates.
Depending on the institution, it may consider:
JAMB/UTME score
Post-UTME score
O’Level results
and potentially other admission criteria.
JAMB’s CAPS framework allows institutions to establish criteria for their programmes, including minimum UTME, Post-UTME and aggregate requirements.
Therefore, always check your chosen institution’s current admission guidelines before treating an online calculation as final.
Method 1: JAMB 50% + Post-UTME 50%
One common method is to give JAMB and Post-UTME equal weight.
The formula can be written as:
JAMB Component = JAMB Score ÷ 8
If Post-UTME is scored over 100:
Post-UTME Component = Post-UTME Score ÷ 2
Then:
Aggregate = JAMB Component + Post-UTME Component
Example
Suppose you scored:
JAMB: 280/400
Post-UTME: 70/100
JAMB component:
280 ÷ 8 = 35
Post-UTME component:
70 ÷ 2 = 35
Aggregate:
35 + 35 = 70%
Your estimated aggregate using this specific formula would therefore be:
70%
This is an example calculation, not a universal JAMB rule.
Method 2: Convert Both Scores to Percentages
Another way to understand the same 50/50 weighting is to first convert each score into a percentage.
JAMB:
280 ÷ 400 × 100 = 70%
Post-UTME:
70 ÷ 100 × 100 = 70%
Then:
(70 × 50%) + (70 × 50%) = 70%
The result is again:
70%
This method is useful when building a calculator because it can easily be adapted to other weightings.
Example With Different Scores
Suppose a candidate has:
JAMB = 300
Post-UTME = 64
Using the illustrative 50/50 formula:
JAMB component:
300 ÷ 8 = 37.5
Post-UTME component:
64 ÷ 2 = 32
Aggregate:
37.5 + 32 = 69.5%
So:
Estimated aggregate = 69.5%
Even though this candidate scored 300 in JAMB, the lower Post-UTME result reduces the combined score.
Method 3: Weighted Aggregate Formula
Some admission systems may assign different weights to each component.
For example, imagine an institution uses:
JAMB = 60%
Post-UTME = 40%
A candidate scores:
JAMB = 280/400
Post-UTME = 75/100
First convert JAMB:
280 ÷ 400 × 100 = 70%
Now apply the weights:
JAMB contribution:
70 × 0.60 = 42
Post-UTME contribution:
75 × 0.40 = 30
Aggregate:
42 + 30 = 72%
Estimated aggregate:
72%
Again, this is an illustrative formula. Use it only if the institution actually specifies those weightings.
What If O’Level Results Are Included?
Some institutions may incorporate O’Level performance into their screening or aggregate methodology.
For example, an institution could theoretically use:
JAMB = 50%
Post-UTME = 30%
O’Level = 20%
Suppose:
JAMB percentage = 70%
Post-UTME = 80%
O’Level converted score = 90%
The weighted calculation would be:
70 × 0.50 = 35
80 × 0.30 = 24
90 × 0.20 = 18
Total:
35 + 24 + 18 = 77%
But you should not assume this formula applies to your university.
The university must specify how O’Level grades are converted and weighted.

JAMB Score vs Cut-Off Mark vs Aggregate Score
These terms mean different things.
JAMB Score
Your actual UTME result.
Example:
265/400
Minimum Admission Score
This is the minimum tolerable UTME score established for an institution category at the national policy level.
For the 2026 admission cycle, JAMB reports minimum tolerable scores of:
Universities: 150
Colleges of Nursing: 150
Polytechnics, Monotechnics, Colleges of Agriculture and Colleges of Education: 100
Innovation Enterprise Institutions: 100.
Institutions can still apply higher programme or institutional requirements.
Aggregate Score
This is the combined admission score calculated according to the institution’s methodology.
Therefore:
JAMB score ≠ aggregate score
and:
National minimum ≠ guaranteed admission

Does a High JAMB Score Guarantee Admission?
No.
Admission can depend on more than your UTME score.
JAMB’s CAPS process supports institution and programme-level admission criteria, and institutions can specify minimum UTME, Post-UTME and aggregate scores along with other criteria.
Your chances may therefore depend on:
- JAMB score
- Post-UTME performance
- Aggregate score
- O’Level requirements
- Subject combination
- Programme competitiveness
- Institution-specific admission criteria
- Available admission capacity
A score that is competitive for one course may not be competitive for another.
Example: Comparing Two Candidates
Consider two candidates using an illustrative 50/50 formula.
Candidate A
JAMB:
310
Post-UTME:
60
JAMB component:
310 ÷ 8 = 38.75
Post-UTME component:
60 ÷ 2 = 30
Aggregate:
68.75%
Candidate B
JAMB:
270
Post-UTME:
78
JAMB component:
270 ÷ 8 = 33.75
Post-UTME component:
78 ÷ 2 = 39
Aggregate:
72.75%
Candidate A has the higher JAMB score.
But Candidate B has the higher aggregate:
72.75% vs 68.75%
This demonstrates why Post-UTME can significantly affect admission ranking where an institution uses this type of combined formula.
How to Use an Admission Predictor
A useful university admission predictor should ask for:
Your JAMB score
Institution
Course
Post-UTME score, if available
O’Level information where relevant
It can then compare your result with the institution’s applicable formula and historical competitiveness.
But the result should be described as:
Estimated admission chance
rather than:
Guaranteed admission
JAMB’s official CAPS system remains the central platform through which admission processing and approval occur.

Frequently Asked Questions
How do I convert my JAMB score to percentage?
Use:
JAMB Score ÷ 400 × 100
For example:
280 ÷ 400 × 100 = 70%
What is 250 in JAMB as a percentage?
250 ÷ 400 × 100 = 62.5%
How do I calculate JAMB and Post-UTME aggregate?
You must first check the formula used by your institution. If it uses an illustrative 50/50 JAMB/Post-UTME system, you can calculate each component at half of the final score and add them together.
Is there one JAMB aggregate formula for all universities?
No. Institutions can establish programme-level admission criteria including minimum UTME, Post-UTME and aggregate scores.
Is 200 a good JAMB score?
It is above the 2026 national minimum tolerable score of 150 for universities, but that does not mean it is competitive enough for every university or course.
Does meeting the cut-off guarantee admission?
No. Programme requirements, aggregate scores, available places and other admission criteria can still affect the outcome.
Final Thoughts
Calculating your JAMB and Post-UTME aggregate score starts with knowing the exact formula used by your institution.
For an illustrative 50/50 system:
JAMB component + Post-UTME component = Aggregate
For example:
JAMB 280 → 35/50
Post-UTME 70 → 35/50
Aggregate = 70%
But do not apply that formula blindly to every university. JAMB’s own admission framework allows institutions to define programme-level criteria, so formulas and required scores can differ.
