MDCAT Aggregate Calculator
Last updated 11 July 2026
Work out the exact MDCAT score you need to hit your target university’s merit aggregate. Put in your Matric and FSC marks, set a target aggregate, and the calculator solves for the MDCAT percentage (and raw marks) you need, using the common 50% MDCAT · 40% FSC · 10% Matric weighting.
Enter your Matric, FSC and MDCAT marks to see your aggregate — or switch to “Score I Need” to plan a target.
How to use this MDCAT aggregate calculator
- Put in your Matric marks and total. The total defaults to 1200; change it if your board differs.
- Do the same for your FSC or HSSC marks.
- Set your target aggregate, the merit percentage your target college tends to close at.
- Read off the MDCAT percentage and the raw marks out of 180 you would need to get there.
- Using a different weighting or different totals? Edit them in the tool, recompute, and check the result against your university’s official admission policy.
How the MDCAT aggregate formula works
Most public-sector medical admissions roll three exams into one merit percentage, your “aggregate”, with the MDCAT weighing the heaviest:
Worked example. Say 90% in Matric, 88% in FSC and 85% on the MDCAT. That is 90 × 0.10 = 9.0, plus 88 × 0.40 = 35.2, plus 85 × 0.50 = 42.5, for an aggregate of 86.7%. The planner above runs this backwards: give it your Matric and FSC marks and a target, and it tells you the MDCAT score that gets you there.
One caution. These weightings and exam totals are estimates. They shift by province, university and year, and some admitting bodies weight the MDCAT differently or use different totals. So treat the number as a planning guide, check it against your target university’s current admission policy, and edit the totals in the calculator if yours differ. For MDCAT 2025 and 2026 the 50/40/10 estimate and the 180-mark paper still hold, so plan around them now and fine-tune once your university confirms its policy.
How one mark, even one decimal, decides your future
Merit lists get decided in the fifth decimal place. That is not an exaggeration. Take two candidates sitting one place apart on a list:
| Merit position | Aggregate |
|---|---|
| #174, got the seat | 95.38380% |
| #175, next in the queue | 95.38330% |
A seat and the wait-list, separated by 0.00050%, the fifth digit after the decimal. Now look at what one mark is actually worth on the 50/40/10 formula:
- 1 MDCAT mark = 50 ÷ 180 ≈ 0.27778 aggregate points. That is more than 550× the gap between those two students.
- 1 FSC mark = 40 ÷ 1200 ≈ 0.03333 points, about 66× the gap.
- 1 Matric mark = 10 ÷ 1200 ≈ 0.00833 points, still around 16× the gap.
In a band packed this tight, one extra correct MDCAT answer does not merely break the tie. It can jump you past hundreds of candidates above you. That is exactly why the calculator shows your aggregate to five decimal places. At the merit boundary the fifth decimal is the line between a seat and a wasted year, and every MDCAT mark still within reach is the cheapest merit you have left to win.
Why the MDCAT is scored out of 180
The MDCAT is 180 MCQs, one mark each, with no negative marking. A correct answer is +1 and a wrong one costs nothing, so your raw score is just how many of the 180 you got right. That raw score is what becomes the 50% MDCAT slice of your aggregate.
Keep two bars separate in your head. Passing is 55% for MBBS and 50% for BDS, and clearing it only makes you eligible. Merit, the number that actually wins a public-college seat, sits a long way higher. The MDCAT 2026 format and passing-marks guide breaks the whole paper down if you want the full picture.
MBBS vs BDS: what aggregate should you aim for?
Rule of thumb: MBBS merit closes higher than BDS, and public colleges close higher than private ones. Past that, there is no single magic number. Closing merit shifts every year and differs by province and university. So instead of chasing a figure off a WhatsApp group, put your own Matric and FSC marks into the planner above and try a few target aggregates to see which MDCAT scores keep you in the running.

Frequently asked questions
- What is the MDCAT aggregate formula?
- A common merit formula weights MDCAT at 50%, FSC at 40% and Matric at 10%: Aggregate % = Matric% × 0.10 + FSC% × 0.40 + MDCAT% × 0.50. Always confirm the exact weighting your university uses, as it can differ.
- How much does the MDCAT count towards the aggregate?
- Around 50% in the common public-sector formula, by far the biggest single component, which is why a strong MDCAT score moves your merit more than anything else you can still change.
- How much does one mark change your MDCAT aggregate?
- On the 50/40/10 formula, one MDCAT mark is worth 50 ÷ your MDCAT total, so about 0.278 points on a 180-mark paper. One FSC mark is worth roughly 0.033 points and one Matric mark about 0.008. Near the merit boundary candidates are often separated by less than a thousandth of a percent, so even part of a single mark can move you several places. That is why this calculator shows the aggregate to five decimal places.
- What aggregate do I need for MBBS in a public medical college?
- Closing percentages change every year and vary by province, but public MBBS seats often sit around 85% or higher. Put your marks into the planner above to see the MDCAT score that gets you there.
- Does the weightage change by university or province?
- Yes. Different admitting bodies and provinces use different weightings and totals, and policies change year to year. The numbers here use the common 50/40/10 estimate, so verify the current official policy for your target university.
- Is this an MDCAT merit calculator too?
- Yes. On the public formula your aggregate percentage is your merit percentage, the exact number the merit lists are sorted on, so this doubles as your merit calculator. Just remember some universities weight the three exams differently, so treat the output as a strong estimate and confirm your target’s policy.
- Does this calculator work for MDCAT 2025 and 2026?
- Yes. The 50/40/10 estimate and the 180-mark paper apply across the recent cycles, and PMDC kept the 2025 curriculum for the 2026 exam, so the maths here holds for both. Always cross-check the current official policy for your admitting university before you lock in a target.
- The MDCAT is out of how many marks?
- 180. One mark for every correct MCQ and nothing deducted for a wrong one, so your raw score is simply how many of the 180 you got right. That raw score then becomes the 50% MDCAT slice of your aggregate. Passing (55% for MBBS, 50% for BDS) is a separate bar from the merit you actually need.
- Is the calculator free?
