Bonus Marks Calculator

Work out bonus marks instantly with clear inputs, formula shown and shareable results.

About Bonus Marks Calculator

Bonus marks are added to the base score and then capped at the maximum, so any excess above the cap is reported separately as marks that could not count. Bonus schemes are often capped, and a student sitting at 98 gains almost nothing from a five mark bonus, which is worth knowing before chasing it.

Formulas

Final marks

final = min(base marks + bonus marks, maximum marks)

Lost bonus

lost = max(0, base + bonus - maximum)

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
