Frequently asked questions
Are these education calculators free to use?
Yes - all 15 tools on this page are free, with no account or sign-up required.
Do these tools use my exact school's grading scale?
They use the standard US 4.0 GPA scale and common letter-grade cutoffs, which match most schools closely. Some schools use slightly different exact cutoffs or a different weighting policy - check your specific school's grading policy if precision matters, like for an official transcript calculation.
Is my grade or GPA information saved anywhere?
No. Every calculation runs directly in your browser - nothing you enter is sent to a server or stored anywhere, unlike some GPA apps that require creating an account.
Which tool should I start with to plan my semester?
Start with the GPA Calculator or Weighted Grade Calculator to see where you currently stand, then use the Target GPA or Final Exam Grade Calculator to work out what you need going forward.
