GPA Calculator

How GPA Calculator works

Turn grade points and credit hours into a GPA on the standard 4.0 scale, using the same arithmetic a registrar uses. 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.

Credits weighted, not averaged

A GPA is a credit-weighted average of grade points: each course's grade point value multiplied by its credit hours, summed, then divided by total credits. That is why a 4-credit A lifts a GPA more than a 1-credit A.

A plain average of grade points ignores credits and produces a different, wrong number for anyone taking courses of unequal size.

The 4.0 scale

The standard mapping is A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0, with plus and minus variants shifting by 0.3 in either direction. Institutions differ on whether an A+ is 4.0 or 4.3, so a GPA is only comparable within one institution's scale.

Some universities use a 10-point or percentage scale; converting between them is not a multiplication.

Cumulative and term GPA

A term GPA uses only that term's courses; a cumulative GPA uses everything. Adding a new term recalculates the cumulative figure from all credits — you cannot average two GPAs unless they have equal credit totals.
