Final Marks Calculator
Combine internal & external at any ratio (30:70…) — or plan the exam score each target needs, with the min-external rule checked.
Internal banked · external pending
24.0 / 100 so far
Internal 24/30 (80.0%) locks in 24.0 points at the 30:70 split. The external can add up to 70.0 more — see below what each target demands.

🏁Internal + external, the way universities combine them
Most Indian universities split every subject into internal assessment and an external exam, combined at a fixed ratio like 30:70. This calculator does that combination exactly — different maximum marks on each side handled correctly — and doubles as a planner: leave the external blank and it shows the exam score every overall target demands. It also checks the rule that trips students up most: the minimum-external requirement, where failing the exam fails the subject no matter how good your internals were.
📊Everything you'd want to know
- Standard splits (20:80, 25:75, 30:70, 40:60, 50:50) plus any custom ratio.
- Internal and external can have different maximums — 30-mark internals with a 70-mark exam, or 40 with 60.
- Planner mode: external blank → the exact exam marks needed for 40 / 50 / 60 / 75 / 90% overall, each with an effort verdict.
- The minimum-external rule, checked separately — with a blunt warning when the total looks fine but the subject still fails.
- A contribution bar showing how many of your final 100 points each side supplies.
- A colour-coded PDF report with contribution bars and the full target table.
🧮The maths
Each side is first converted to a percentage of its own maximum, then scaled by its weight. That's why 24/30 internals at a 30:70 split contribute 80% × 30 = 24 points — and why the external exam, worth 70 of the final 100, dominates the result.
💡Rules that decide real results
- The minimum-external rule (often 33–40%) is applied before combining — a 95% internal cannot rescue a failed exam.
- Internal marks are usually capped, moderated, or scaled by the university — the marks your college sends may differ from your classroom score.
- Strong internals are the cheapest marks in the degree: they're earned over a whole term, not three hours.
- Back-paper/revaluation usually applies to the external component only; internals typically carry over.
💡 Frequently Asked Questions
How are final marks calculated from internal and external?+
Convert each to a percentage of its own maximum, multiply by its weight, and add. Internal 24/30 (80%) and external 42/70 (60%) at a 30:70 split give 80×0.3 + 60×0.7 = 66%. The calculator handles any ratio and any pair of maximums.
What is the 30:70 pattern in university exams?+
It means internal assessment contributes 30% of the final subject mark and the external (semester) exam 70%. Common alternatives are 25:75, 40:60, and 50:50 — pick the chip that matches your scheme of examination.
How many marks do I need in the external exam?+
Leave the external field blank and the planner shows the exact marks needed for every overall target — for example, with 24/30 internals at 30:70, reaching 60% overall needs 36 of 70 in the exam. Each target carries an honest effort verdict.
Can good internal marks compensate for a failed external?+
Usually not. Most universities require a minimum percentage in the external exam separately (often 33–40%); score below it and the subject fails regardless of the combined total. Enter that rule in the calculator and it checks your external against it explicitly.
Why do my internal marks differ from what my college gave?+
Universities often moderate or scale internal marks before combining — capping them relative to external performance or class averages. The final marksheet uses the moderated figure, so treat classroom internals as provisional.
