Why trust these numbers

Every calculator shows its formula.

Each tool explains exactly how it calculates, with a worked example and the sources behind it. Where a result is an estimate — AP scores, snow days — we say so and show the range.

Frequently asked questions

What is The Homework Site?
The Homework Site is a free, independent resource for students, parents and teachers. It offers grade, GPA and test-score calculators, classroom tools such as the EZ Grader and random group generator, and plain-English guides about homework, studying and AI in school. There are no accounts, no paywalls and nothing to install, and every guide lists the sources behind its numbers.
Are the calculators on The Homework Site really free?
Yes. Every calculator and classroom tool on The Homework Site is free to use with no sign-up, including the grade calculator, final grade calculator, high school GPA calculator, AP Score Calculator and Snow Day Calculator. No company pays to be included or ranked on the site, and most tools can also be embedded free on a class or school website without ads or tracking.
Does The Homework Site save the grades or names I type?
No. The Homework Site tools run entirely in your browser, so grades, names and scores you type are not sent to the site. Some tools remember your last inputs in your browser’s own storage so you do not have to retype them, and clearing your browser data removes them. Student names typed into teacher tools never leave your device.
How accurate are The Homework Site calculators?
Each calculator on The Homework Site shows its formula with a worked example you can check by hand, and lists the sources behind any outside data, such as AP cutoffs, SAT and ACT conversions or state kindergarten cutoff dates. Formulas are tested against hand-worked examples before publishing. Score predictors for AP, SAT, ACT and PSAT give estimates, not official scores, and say so on the page.
How much homework is normal for my child?
A common guideline is the 10-minute rule: about 10 minutes of homework a night per grade level, so 30 minutes in 3rd grade, 60 in 6th and two hours in 12th. Research links homework to achievement most clearly in grades 7 to 12, and beyond about two hours a night in high school more homework stops helping. The Homework Site’s homework time calculator compares the guideline with your child’s real evenings.
Is this the same homework site schools used in the 2000s?
No. From 2000 to about 2013 this web address hosted an unrelated homework-posting service for schools. Today’s site is run by a new, independent team and is not affiliated with that service. Old links to its pages, documents and school sections no longer work, and The Homework Site does not hold any of its data.
