About Calcade
A free online calculator platform for the maths you actually run into day to day.
What is Calcade?
Calcade (calcade.app) is a free online calculator platform: a fast expression calculator plus 51 focused, single-purpose tools for the everyday, finance, health, study, DIY and statistics maths people look up most — a graphing calculator and a maths diagram generator, SIP and salary, CGPA and attendance, percentages, GST, EMI, BMI, tiles and paint, unit conversions and more. Every tool lives at its own page, does one job well, and shows its result as you type.
No signup, ever
Every calculator on Calcade is free to use with no account, no signup and no paywall. Calculations run entirely in your browser — nothing you type is sent to a server or stored anywhere except your own device's local history, which you can clear at any time.
Fast and simple by design
Calcade is built to be quick: open a calculator, get an answer, move on. There's no clutter between you and the result, and each tool page includes a short explanation of the formula behind it, so the "how" is there if you want it and out of the way if you don't.
The tools
The full set is organised by category on the tools page. A few good places to start:
- Graphing Calculator — Plot equations, functions, inequalities, tables and data on an interactive graph.
- Maths Diagram Generator — Create clean mathematical diagrams, add measurements and labels, and export them instantly.
- Percentage Calculator — Percentages of a value, ratios, and increase or decrease.
- GST Calculator — Add GST to a price, or pull it back out of an inclusive one.
- SIP Calculator — See what a monthly SIP could grow to, split into amount invested and returns.
- CGPA to Percentage Calculator — Convert CGPA or GPA to a percentage with CBSE, VTU, 10-point or custom formulas.
Every category has its own shelf on the /tools page — finance & investment, academic & student, everyday, health & fitness, construction & diy, math & statistics, conversion — so you can browse instead of searching if you're not sure which tool you need.
