COMSATS Aggregate Calculator (NTS NAT Merit)
Work out your COMSATS aggregate from matric, intermediate and NTS NAT marks.
How the COMSATS aggregate is calculated
COMSATS University Islamabad (CUI) does not hold its own entry test for most undergraduate programmes. It uses the NTS NAT (National Aptitude Test) score with your academic record. The undergraduate weights are 10% matric, 40% intermediate and 50% NTS, and the same formula is used across the campuses.
Formula: aggregate = (matric % × 0.10) + (intermediate % × 0.40) + (NAT % × 0.50).
| Part | Weight | Marks used |
|---|---|---|
| Matric or equivalent | 10% | Obtained ÷ total |
| Intermediate or equivalent | 40% | Obtained ÷ total |
| NTS NAT | 50% | Score ÷ 100 |
Worked example
Matric 950 out of 1,100, intermediate 950 out of 1,100 and a NAT score of 65 out of 100:
- Matric: 950 ÷ 1,100 × 10 = 8.64
- Intermediate: 950 ÷ 1,100 × 40 = 34.55
- NTS NAT: 65 ÷ 100 × 50 = 32.50
- Aggregate: 75.68%
How your NAT score changes the aggregate
| NTS NAT score | 70% in Matric and Inter | 80% in Matric and Inter | 90% in Matric and Inter |
|---|---|---|---|
| 50% (50 out of 100) | 60.00% | 65.00% | 70.00% |
| 60% (60 out of 100) | 65.00% | 70.00% | 75.00% |
| 70% (70 out of 100) | 70.00% | 75.00% | 80.00% |
| 80% (80 out of 100) | 75.00% | 80.00% | 85.00% |
| 90% (90 out of 100) | 80.00% | 85.00% | 90.00% |
Each extra NAT mark adds half a point to the aggregate.
Things to know
- NAT category: take the NAT that matches your intermediate group, such as NAT-IE for pre-engineering or NAT-ICS for computer science.
- Validity and attempts: a NAT result is valid for a limited period and the test can be taken more than once. Enter your best valid score.
- Special programmes: some programmes, such as architecture and design, add their own test or interview, so their merit is worked out differently.
- Campuses: the formula is the same, but closing merit differs by campus and programme.
O Level and A Level students
Grades cannot be entered directly. Get your equivalence from IBCC first, then enter the equivalence marks and total in the Matric and Intermediate boxes.
What this estimate leaves out
- Closing merit: your aggregate only tells you where you stand. Whether it is enough depends on the closing merit of the programme and campus, which changes every year.
- Quotas and reserved seats: these are handled outside this formula.
- Rule changes: universities can change their weights between admission cycles. Confirm the current formula on the university’s admissions page before you rely on the result.

Frequently asked questions
How do I calculate my COMSATS aggregate?
Multiply your matric percentage by 0.10, your intermediate percentage by 0.40 and your NTS NAT percentage by 0.50, then add them.
What is the COMSATS merit formula?
For undergraduate programmes: 10% matric, 40% intermediate or equivalent and 50% NTS.
Which test does COMSATS use?
COMSATS uses the NTS National Aptitude Test (NAT) for most undergraduate admissions.
What are the total marks of the NAT?
The NAT is marked out of 100.
How much does one NAT mark add to my aggregate?
With a 50% weight and 100 total marks, each NAT mark adds 0.5 points.
Is the COMSATS formula the same at every campus?
The weights are the same. The closing merit is different for each campus and programme.
