MDCAT aggregate formula is the official PMDC method used to combine your Matric, FSc and MDCAT marks into a single percentage for MBBS and BDS admissions in Pakistan. If you know your marks in all three, you can work out your aggregate in under a minute — this guide shows the formula, a step-by-step worked example, the 2026 eligibility marks and the NUMS variation.
The MDCAT Aggregate Formula
The official formula, published by the Pakistan Medical and Dental Council (PMDC), is:
Aggregate % = (Matric obtained ÷ Matric total × 10) + (FSc obtained ÷ FSc total × 40) + (MDCAT obtained ÷ 180 × 50)
Each part is first turned into a percentage, then multiplied by its weightage. The weightage is Matric/SSC 10%, FSc/HSSC Pre-Medical 40% and MDCAT 50%, so the MDCAT carries half of your aggregate.
| Component | How it is counted | Weightage |
|---|---|---|
| Matric / SSC | Obtained marks ÷ total marks | 10% |
| FSc / HSSC Pre-Medical | Obtained marks ÷ total marks | 40% |
| MDCAT | Obtained marks ÷ 180 | 50% |
| Total aggregate | Sum of the three parts | 100% |
Use your own totals carefully. Matric is usually out of 1100, although it is 1200 for Punjab and KPK boards from 2023, when a Quran/Nazra subject was added. FSc is usually out of 1100. The MDCAT is always out of 180. MDCAT 2026 has 180 MCQs, 1 mark each, out of 180, with no negative marking, and it was held on 20 September 2026. If you only need your MDCAT percentage first, see our guide on how to calculate MDCAT marks in Pakistan.
Step-by-Step Worked Example
Use the MDCAT aggregate formula with a real example. Take a student with Matric 1000/1100, FSc 950/1100 and MDCAT 150/180 and work through each part:
- Matric: 1000 ÷ 1100 × 10 = 9.09
- FSc: 950 ÷ 1100 × 40 = 34.55
- MDCAT: 150 ÷ 180 × 50 = 41.67
- Add them together: 9.09 + 34.55 + 41.67 = 85.30%
So this student’s MDCAT aggregate is 85.30%. Because the MDCAT is worth 50% spread over 180 marks, each MDCAT mark adds about 0.2778% to the aggregate (50 ÷ 180). That is why a handful of extra MDCAT MCQs can move your merit position far more than a few extra FSc marks.
MDCAT Eligibility Marks 2026
Before your MDCAT aggregate formula result matters, you must clear the minimum MDCAT score. For 2026 the eligibility marks are 55% (99/180) for MBBS and 50% (90/180) for BDS. Scoring below these marks means you cannot apply, even with strong Matric and FSc results. Remember that eligibility is only the minimum to apply — the closing merit of a college is usually much higher than 55%.
NUMS Aggregate
NUMS runs its own entry test, which is out of 200 marks rather than 180, but the MDCAT aggregate formula works the same way for NUMS, with the same 10/40/50 weightage: 10% Matric, 40% FSc and 50% NUMS test. So for NUMS, replace the MDCAT part of the formula with (NUMS obtained ÷ 200 × 50). Read our full breakdown of the NUMS entry test weightage in Pakistan for the subject-wise split.
Common Mistakes
- Using the wrong totals: dividing Matric marks by 1100 when your board total is 1200, or vice versa.
- Dividing the MDCAT by 200: the MDCAT is out of 180; 200 is the NUMS test total.
- Mixing up percentage and aggregate: your MDCAT percentage (marks ÷ 180 × 100) is not your aggregate — the aggregate also includes Matric and FSc.
- Forgetting the weightage: adding the three percentages together without multiplying by 10%, 40% and 50% gives a meaningless number over 100%.
Caution: a few universities and some self-finance and overseas seats use a different split — always confirm the weightage in your admitting university’s prospectus before relying on a number. The 10/40/50 split above is the standard PMDC formula for public-sector MBBS and BDS admissions.

FAQs
What is the MDCAT aggregate formula?
Aggregate % = (Matric obtained ÷ Matric total × 10) + (FSc obtained ÷ FSc total × 40) + (MDCAT obtained ÷ 180 × 50).
What is the weightage for MDCAT aggregate in Pakistan?
Matric 10%, FSc 40% and MDCAT 50%.
How many marks are needed in MDCAT for MBBS in 2026?
At least 55%, which is 99 out of 180. For BDS the minimum is 50%, or 90 out of 180.
How much does one MDCAT mark add to the aggregate?
About 0.2778%, because 50% weightage is spread over 180 marks.
Is the NUMS aggregate calculated the same way?
Yes, with the same 10/40/50 weightage — only the test total changes, to 200 marks for NUMS.
Work out your own number with the MDCAT aggregate formula above, then compare it with the closing merit of the colleges on your list — and double-check the weightage in each prospectus before you apply.
