Exam Percentage Calculator

How Exam Percentage Calculator works

Turn subject marks into an overall percentage and grade. Paste one subject per line with obtained and total marks; the tool totals everything and grades it. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

Weighted totals

Each component contributes its own percentage multiplied by its weight. A 75% coursework at 30% weight and an 80% exam at 70% gives 0.75 × 30 + 0.80 × 70 = 78.5% overall.

That is the whole calculation — the trap is entering weights that do not sum to 100, which silently rescales the result.

Checking the weights first

Before trusting a result, add the weights. If they total 90 or 110, the output is meaningless even though the arithmetic is correct. Most syllabi state the split explicitly; if yours does not, ask.

Rounding

Institutions usually round the final percentage once, not each component. Rounding components first can move the total by half a percent, which occasionally decides a grade boundary.
