ECAT and engineering admissions in Pakistan
ECAT (Engineering College Admission Test) is the entry test used by UET Lahore, UET Peshawar, UET Taxila, and several other engineering universities in Pakistan. Your aggregate combines Matric, FSc Pre-Engineering, and ECAT into a single number that determines your position on the merit list for each department.
The standard formula
Aggregate = (Matric % × 0.17) + (FSc % × 0.50) + (ECAT % × 0.33)
FSc carries the largest single weight. A student with a 90% FSc gains 45 percentage points toward the aggregate from that component alone. This is why students with strong FSc results often clear engineering merit even with modest ECAT performance.
Worked example
| Component | Score | Weight | Contribution |
|---|---|---|---|
| Matric | 88% | 17% | 14.96 |
| FSc Pre-Engineering | 84% | 50% | 42.00 |
| ECAT (288 out of 400) | 72% | 33% | 23.76 |
| Aggregate | 100% | 80.72% |
An 80.72% aggregate is competitive for Civil, Chemical, and Mechatronics at UET, but would likely fall short of CS and EE. Improving ECAT by 20 marks (from 288 to 308 out of 400) adds 1.65 percentage points to the aggregate. Improving FSc by 1 percentage point adds 0.5. The relative impact clearly favours a strong FSc result.
Closing merit by department (UET Lahore, approximate)
| Department | Typical closing aggregate |
|---|---|
| Computer Science | 85% to 88% |
| Electrical Engineering | 83% to 86% |
| Mechanical Engineering | 80% to 83% |
| Civil Engineering | 78% to 82% |
| Chemical Engineering | 77% to 81% |
| Mechatronics Engineering | 79% to 83% |
These are estimates from recent admission cycles. Closing merits shift each year with applicant numbers. Check UET's official merit lists published after each admission cycle for the most accurate figures.
Formulas at other engineering universities
| University | Test used | Matric | FSc | Test |
|---|---|---|---|---|
| UET Lahore, Peshawar, Taxila | ECAT | 17% | 50% | 33% |
| NUST | NET | 10% | 15% | 75% |
| FAST-NUCES | NU test | 10% | 40% | 50% |
| COMSATS | NTS / SAT | 25% | 50% | 25% |
| NED University | ECAT | 15% | 50% | 35% |
NUST weights its own test at 75%, making the NET score the dominant factor in its aggregate. Apply the correct formula for each university you are targeting.
How to use this calculator
- Enter your Matric percentage.
- Enter your FSc Pre-Engineering percentage.
- Enter your ECAT score and the total marks (usually 400).
- Read your aggregate in the result panel.
- Compare against the closing merit of your target department.
When to use this calculator
Use it as soon as ECAT results are announced to calculate your aggregate before merit lists are published. Use it before the test with target scores to plan how much ECAT improvement is needed for a specific department. For MBBS admission, use the MDCAT Aggregate Calculator. For universities not listed in the formula table above, use the Merit Calculator with custom weights.
Common mistakes
Entering raw ECAT marks as a percentage. If your ECAT score is 280 out of 400, enter 280 in the score field and 400 as the total. The calculator converts to 70% before applying the 33% weight. Entering 280 directly as a percentage would produce a completely wrong aggregate.
Using the UET formula for NUST. NUST's NET carries 75% of the aggregate, not 33%. Applying the UET formula to a NUST application significantly underestimates or overestimates your aggregate depending on your test score.
Ignoring self-finance seat merit lists. Public engineering universities offer both open merit and self-finance seats. Self-finance seat merit lists typically close lower than open merit. If your aggregate falls short of open merit, check the self-finance closing merit separately.

Disclaimer: Aggregate is calculated using the standard UET ECAT formula. Other universities use different weights. Closing merits shown are historical estimates and change each admission cycle. Always refer to the official university merit lists for current figures.
