Two students score the same marks in MDCAT and one gets a seat in a public medical college while the other does not — because the admission aggregate is not the MDCAT score, it is a weighted mix of three results. This MDCAT aggregate calculator guide gives you the official formula, works it through with real numbers, and shows you exactly what MDCAT score you need for your target aggregate. No guesswork, no invented closing merits: just the formula and the arithmetic.
MDCAT aggregate calculator: the official 10/40/50 formula
The aggregate is a single percentage out of 100 that ranks every MBBS and BDS applicant. It is set by the Pakistan Medical and Dental Council's Medical and Dental Undergraduate Education (Admissions, Curriculum and Conduct) Regulations 2025, and it is applied by every admitting university in the country — UHS in Punjab, KMU in Khyber Pakhtunkhwa, SZABMU in Islamabad, and the Sindh and Balochistan authorities. The formula is:
Aggregate % = (Matric marks ÷ Matric total × 10) + (FSc marks ÷ FSc total × 40) + (MDCAT marks ÷ MDCAT total × 50)
In other words, Matric (SSC) counts for 10%, FSc Pre-Medical (HSSC) counts for 40%, and the MDCAT counts for 50%. For the 2026 cycle the standard totals are Matric out of 1100, FSc out of 1100, and MDCAT out of 180. Remember the denominator: MDCAT 2026 is out of 180, not 200. Older results were out of 200, and a result stays valid for three years, so if you are using an older result, enter 200 as the total for that result.
MDCAT aggregate calculator: the 2026 test facts you need
| Fact | 2026 cycle |
|---|---|
| Test date | 20 September 2026 (moved from 16 August 2026) |
| Format | Paper-based, 180 MCQs, 3 hours, in English |
| Subject split | Biology 81, Chemistry 45, Physics 36, English 9, Logical Reasoning 9 |
| Negative marking | None — one mark per correct answer |
| Passing for MBBS | 55% — 99 out of 180 |
| Passing for BDS | 50% — 90 out of 180 |
| Registration fee | Rs 9,000 normal, Rs 13,000 late (closed 8 / 13 July 2026) |
| Result validity | Three years |
One MDCAT mark is worth 0.2778% of your aggregate — as much as about 8 FSc marks. Ten extra MDCAT marks add 2.78% to your aggregate. That is why the test carries half your future: it is the only one of the three components you can still change, and it moves the total faster than anything else.
MDCAT aggregate calculator: worked examples
Example 1. Matric 1000/1100, FSc 950/1100, MDCAT 165/180. Matric: (1000 ÷ 1100) × 10 = 9.09%. FSc: (950 ÷ 1100) × 40 = 34.55%. MDCAT: (165 ÷ 180) × 50 = 45.83%. Aggregate = 9.09 + 34.55 + 45.83 = 89.47%. UHS publishes the final aggregate to four decimal places, so this would appear as 89.4697%.
Example 2. Matric 950/1100, FSc 900/1100, MDCAT 150/180. Matric: 8.64%. FSc: 32.73%. MDCAT: 41.67%. Aggregate = 83.03%.
Example 3 — working backwards. You want an aggregate of 90% and your Matric is 95% and your FSc is 90%. Matric gives 9.50%, FSc gives 36.00%, so you need 44.50% from MDCAT. That means (44.50 ÷ 50) × 180 = 160.2, so you need at least 161 out of 180 (89.4%). This is the honest way to set a target: decide the aggregate first, then calculate the MDCAT score it demands.
Example 4 — what one mark is worth. Two students have identical Matric and FSc. One scores 160 in MDCAT, the other 170. The difference is 10 marks × 0.2778% = 2.78% of aggregate. In a merit list where hundreds of students sit within one percentage point, 2.78% is the difference between a public-sector seat and the waiting list.
MDCAT aggregate calculator: what score you need for a public college
Passing MDCAT is not the same as getting a seat. The passing floor is 55% for MBBS and 50% for BDS, but public medical colleges close far above the minimum — in recent cycles, competitive public colleges have closed in the high 80s and low 90s of aggregate. The exact 2026 closing merits are not published yet: they are only known once UHS, KMU and the other admitting universities publish their merit lists, so any page that quotes a 2026 closing merit today is guessing. Use the rule above instead: take the last published closing aggregate for your target college, add a safety margin of 1–2%, and work backwards to the MDCAT score you need. If your target college closed at 91% last year, aim for 92–93% this year, and calculate the MDCAT score that requires.
Notes and exceptions
There are no extra marks for Hafiz-e-Quran in the MDCAT aggregate — the PMDC's 2025 regulations and a Supreme Court judgment rule them out. NUMS-affiliated colleges use the NUMS entry test, not MDCAT, so this formula does not apply to them — check the NUMS prospectus separately. Some private colleges use the same 10/40/50 formula, but a few set their own weightings, so confirm the formula on the college's own admission page before you rely on it. And remember: the aggregate is calculated from percentages of each total, not from raw marks added together — a common mistake is to add 1000 + 950 + 165 and divide by something, which gives a meaningless number.
Frequently asked questions
What is the MDCAT aggregate formula? 10% Matric + 40% FSc + 50% MDCAT, applied as (obtained ÷ total × weight) for each component and added together. The MDCAT total for 2026 is 180.
How many marks do I need in MDCAT for MBBS? At least 99 out of 180 (55%) to be eligible, but a public-sector seat needs far more — work backwards from your target college's last published closing aggregate.
Is there negative marking in MDCAT? No. MDCAT 2026 has no negative marking: one mark per correct answer, 180 MCQs in 3 hours.
How long is an MDCAT result valid? Three years. An older result out of 200 is still valid — use 200 as the MDCAT total when you calculate that aggregate.
