Free Calculators for Students, Teachers and Everyday Money Decisions
Alexx Access calculators are built for the questions people actually ask during a school term or a big purchase. The GPA Calculator works the way colleges do: add every course with its credit hours and grade, and it returns both the credit-weighted GPA and the simple unweighted average on the standard 4.0 scale, so you can see exactly how one heavy course moves your result. The Final Grade Calculator answers the end-of-semester question - given your current grade, the grade you want and how much the final exam is worth, it tells you the exact score you need, including when the target is already secured or mathematically out of reach. The Attendance Calculator is just as practical: enter classes held and attended to see your current percentage, how many classes in a row you must attend to reach 75% or 80%, and how many you can still afford to miss before dropping below those common thresholds.
Study tools go beyond numbers. The Essay Word Counter tracks words, characters, sentences and paragraphs as you type and estimates reading and speaking time, with a read-aloud button that uses your device's speech synthesis so you can hear your draft. The Citation Generator formats website, book and journal references in APA, MLA and Chicago styles. Teachers and class reps can use the Random Name Picker & Team Maker for fair cold-calling and balanced groups, the Flashcard Maker for quick revision decks, the Weekly Timetable Maker for an editable schedule you can download, and the Printable Paper Generator for clean A4 graph, lined and dot-grid PDF pages. The Age Calculator rounds out the set with an exact years-months-days breakdown and total days lived.
On the finance side, the Mortgage Calculator breaks a home loan into monthly principal and interest, property tax, insurance, total payment and total interest over the full term. The Loan Amortization Schedule shows every single month of any loan - payment, principal, interest and remaining balance - and exports the whole table as a CSV file. The Compound Interest Calculator shows how savings grow with different compounding frequencies and monthly contributions, the Percentage Calculator handles percentages of numbers, increases, decreases and discounts, and the Unit Converter covers length, mass, temperature, data storage, speed and area. Every tool on this page runs entirely in your browser: no accounts, no uploads and no waiting.
