Free Education & Study Calculators
GPA, grades, percentages, and study tools that show every step of the math — free, no sign-up, and everything runs in your browser.
About these tools
The Educate section covers the math students actually need on a deadline: working out a GPA from course grades and credit hours, figuring out exactly what score the final exam requires to land a target grade, and everyday percentage calculations for assignments, discounts, and statistics.
Every calculator shows its work — the GPA tool displays the grade-point values and credit weighting, and the final-grade tool shows the formula it solves — so these double as a way to learn the method, not just get the answer.
Like everything on Tallyloom, the tools are free, need no account, and run entirely in your browser: grades and scores you enter are never uploaded anywhere.
Frequently asked questions
Are these calculators free for students?
Yes — every Tallyloom tool is free, with no account, watermark, or usage limit.
Which GPA scale do you use?
The standard US 4.0 scale with plus/minus steps (A = 4.0, A− = 3.7, B+ = 3.3, and so on), weighted by credit hours. Schools vary slightly — check your institution's published scale for official numbers.
Is my grade data private?
Yes. Everything you type is processed on your device and never sent to a server.
