How GPA is calculated
Your grade point average is a credit-weighted average, which means harder courses worth more credits count for more. Each letter grade maps to points (A is 4.0, B is 3.0, and so on). You multiply each course's points by its credits, add those up, then divide by your total credits. The calculator does all of that as soon as you hit the button.
Why credits matter
A simple average treats every course equally, but a 4-credit course should pull harder on your GPA than a 1-credit one. That is why an A in a big course lifts your GPA more than an A in a small one — and why a poor grade in a heavy course stings more.
The grade scale used here
This tool uses the common US 4.0 scale with pluses and minuses (A = 4.0, A− = 3.7, B+ = 3.3, and so on down to F = 0). Schools vary, so if yours uses a different scale your official GPA may differ slightly.
Frequently asked questions
What is a good GPA?
It depends on context, but 3.0 is often seen as solid, 3.5+ as strong, and 3.7+ as excellent. Many programmes and employers look at the wider picture too.
How do I raise my GPA?
Stronger grades in higher-credit courses move it the most. The maths rewards consistency across your heaviest classes.
