Calculate your course grades, track your GPA, or convert between grading systems in seconds. All free, all private, all without creating an account.

How to Use Free Tools
Free Four Calculator Groups
Our free grade calculators and GPA tools work as a system, not isolated tools. Most academic calculations start at the course-level Grade Calculators, aggregate to the program level, GPA Calculators, and then translate to different formats when needed, Conversion Calculators.
No Signup, ever
Every tool works immediately. No accounts, no email, no login walls.
100% private
All calculations run locally in your browser. Your grades never touch our servers.
Always free
No subscriptions, no premium tiers, no paywalls on any calculator.
Standard formulas
Built from the same weighting and threshold methods your syllabus describes.
Choosing Your Grading Scheme From our gRADE cALCULATOR tools
By default, the calculators use the standard US letter grade scale (A+ through F). But if you’re studying under a different system, you can switch. The options include
US Letters
The familiar A+/A/A-/B+… down to F. This covers most American colleges and universities, plus many international schools that follow the US model.
UK Classes
First, 2:1, 2:2, Third, and Fail. If you’re at a British university or studying under their degree classification system, select this one. The thresholds are built in (70% for a First, 60% for a 2:1, and so on), but you can adjust them if your institution uses slightly different cutoffs.
ECTS
The European Credit Transfer and Accumulation System uses its own A through F scale with slightly different thresholds than the US version. This is relevant if you’re at a European university or taking courses that award ECTS credits.
Australian
 HD (High Distinction), D (Distinction), CR (Credit), P (Pass), NN (Not Negotiable/Fail). Australian universities each have their own specific cutoffs, so the “Edit thresholds” option is particularly useful here.

What These Free Grade Calculators And GPA Tools Do Not Do
These free Grade Calculators and GPA tools are trackers, not academic advisors. They perform the math accurately based on the inputs you provide, but they can’t tell you whether you should drop a class, whether a B+ is good enough for your goals, or how much a single grade will affect your future. For those decisions, talk to your academic advisor, professors, or the admissions office at schools you’re applying to.
Grade calculations are approximations when converting between systems. A 3.5 GPA translates to different things at different institutions. Oxford lists a 3.5 GPA as equivalent to a strong 2:1, but that’s their admissions assessment, not an official transcript conversion. If you need a formal credential evaluation for visa applications or international transcript verification, use WES (World Education Services) or UK ENIC, the official evaluation services recognized by governments and universities.
These free grade Calculators and GPA tools do not handle every edge case. Some institutions use unique grading systems, apply curves in non-standard ways, or have policies like replacing your lowest exam score or dropping certain grades. If your situation is unusual, these tools provide a starting point, but verify against your institution’s official calculation method.
