Calculators
Calculators handle the arithmetic that is easy to set up and easy to get wrong: grade point averages and percentages. They show the working so you can check the result rather than trust a black box.
Write down the inputs before you start. A GPA depends on credits and grade points; a percentage change depends on which value is the starting point. Most disagreements about the answer are disagreements about the input.

Common questions
How is GPA calculated?
The common method multiplies each course grade point by its credit value, adds those products, and divides by the total credits. Schools differ on how they treat repeats, transfers, and non-credit courses, so check the official rule before relying on the total.
What is the difference between percent and percentage points?
A change from 10% to 15% is an increase of 5 percentage points, but a 50% increase in the value itself. Percent compares a change to the starting value; percentage points compare two percentages directly. Use the right one or the result will overstate the change.
Can I use these calculators for an official transcript?
Use them for planning and checking, not as an official record. Your institution calculates the GPA that appears on your transcript, and it may weight repeats, honours courses, or transfers differently. Ask the registrar which rule applies to your programme.
