The 8 calculators every high school and college counselor uses.
GPA math, test-score conversions, and 'what do I need on the final' calculations — the questions students ask weekly. These tools let you answer them in seconds, with the receipts to back up the answer.
- • Calculate weighted, unweighted, and cumulative GPA in front of the student so the conversation moves to action items instead of debating Naviance numbers.
- • Convert SAT to ACT (and back) for college list balancing — students applying to test-flexible schools need both numbers in the same conversation.
- • Embed the GPA and final-grade calculators on your school counseling office page so students get answers at midnight before report cards drop, not at your office door at 7:45am.

Open calculatorA junior walks in two weeks before transcripts go out. Here's the meeting.
Maya Singh is a junior with a 3.4 unweighted, 3.8 weighted, two AP classes, and a panicked face. She's looking at a list that includes a mid-tier private and two state flagships and she's convinced she's already aged out of one of the flagships. She has 14 minutes before her next class. You have to be useful right now.
Open the cumulative GPA calculator with her actual semester grades from her transcript. The 3.4 she keeps quoting is from the end of sophomore year — first semester junior is already in, and she's a 3.55 on the running unweighted now. Show her the screen. The number itself is reassurance she didn't think she had.
Then run the grade calculator for her current AP US History class — she's got a 87 going in, the final is 25% of the grade, and the final grade calculator says she needs an 81 on the final to lock in an A-. That's doable. The conversation shifts from existential to tactical in under two minutes. She has a thing she can study for and a number she can hit.
Last five minutes: she scored a 1290 on her PSAT, has a Saturday SAT in three weeks, and the flagship she wants reports a 25th-percentile composite of 1310. Run the SAT score calculator with realistic sectional growth — math 640 → 670 with practice, R/W 650 → 660 — and the calculator gives her 1330. She doesn't need to be in the 75th percentile of admits. She needs to be inside the middle 50, and she has a plan to get there. She leaves with three concrete numbers, a realistic college list, and the spring schedule she actually has time to execute. The calculators didn't replace your counseling. They made it possible to fit the counseling into 14 minutes.

Frequently Asked Questions
Are these GPA calculators accurate for our school's specific weighting system?
The calculators support the most common scales — 4.0 unweighted, 5.0 weighted (AP/honors +1.0), and 100-point scales. For schools with non-standard weighting (e.g., AP +0.5 only, or 4.5 weighted scale), set the weight per course manually. The math is transparent — you can see how each course contributes to the average.
Can I embed the GPA calculator on our school counseling page?
Yes. Every calculator has a one-click embed builder. Pick colors and fonts to match your school site (Schoology, PowerSchool, Naviance landing pages, or a standalone counseling site). Output is a single iframe — works on any school CMS that allows custom HTML. Free, no signup, no student data collected.
Will the embedded calculator collect any student data we'd be liable for under FERPA?
No. All calculations run client-side in the student's browser — nothing is sent to our servers, stored, or tracked. There's no PII collection, no cookies set on student visitors by us, and no FERPA exposure. We don't know who used the calculator, what they entered, or what answer they got.
Can students save their scenarios or come back to a saved GPA projection?
Not in the standard embed — values reset on page load. For some workflows that's actually preferred (privacy by default for shared school computers). If you want save-state functionality on a school district-wide deployment, that's a custom build — reach out via contact.
Do you have a college admissions scoring or chance calculator?
No — chance calculators rely on data we don't collect (institutional admit rates by GPA/test bands), and the ones that exist (CollegeVine, etc.) are noisy enough that we'd rather not publish a worse version. Our calculators stick to math your students can verify themselves.
Which calculator gets the most use on a school counseling site?
The final grade calculator, by a wide margin — it spikes hard in May and December and is the highest-engagement page on most school counseling sites that publish it. The GPA calculator is steadier traffic year-round. Embed both.
