What does this tool do?
This free GPA calculator computes your Grade Point Average on the standard 4.0 scale. Add each course with its letter grade (A through F, including + and − grades) and credit hours, and your weighted GPA updates instantly. Add as many courses as you need — no limit.
How does the gpa calculator work?
Each letter grade maps to points (A = 4.0, A− = 3.7, B+ = 3.3 … F = 0). GPA = Σ(grade points × credits) ÷ Σ(credits). A 3-credit A and a 4-credit B give (4.0×3 + 3.0×4) ÷ 7 = 3.43.
Frequently Asked Questions
What GPA do the letter grades convert to?
On the most common US scale: A/A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, C− = 1.7, D+ = 1.3, D = 1.0, F = 0. Some schools weight honors/AP courses up to 5.0 — check your institution's policy.
What is a good GPA for college and jobs?
A 3.0+ is generally considered solid; 3.5+ qualifies for many honors lists and competitive internships; 3.7+ is typically needed for top graduate programs. Many large employers use a 3.0 cutoff in application filters, though experience increasingly outweighs GPA after your first job.
Is the GPA calculator really free?
Yes — 100% free with no hidden charges, trial limits, or premium tiers for core features. You don't need to create an account or enter an email address. The site is supported by non-intrusive display ads, which keeps every tool free for everyone.
Is my data private when using the GPA calculator?
Completely. The GPA calculator runs entirely in your browser using JavaScript — nothing you type or upload is sent to our servers. When you close the tab, your data is gone. This makes it safe for confidential documents, financial figures, and personal information.
Does the GPA calculator work on mobile phones?
Yes. The GPA calculator is built mobile-first and works on any phone or tablet with a modern browser — iPhone (Safari), Android (Chrome), and everything in between. The layout adapts to small screens, so buttons and inputs stay easy to tap on a 375px-wide display.
Do I need to install anything to use the GPA calculator?
No. The GPA calculator works directly in your web browser — no downloads, no extensions, no signup. Just open the page, use the tool, and get your result instantly. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
