About All Calculator

All Calculator is a free online calculator built for people who need fast, reliable answers to everyday maths problems. We built this site because the best free calculators online were either too cluttered with ads, too complicated to use on a phone, or required a login just to access a basic tool. We wanted something simpler.
All Calculator is run by Tanveer Anwar & Muhammad Abbas, based in Faisalabad, Pakistan. Our goal is to build the most practical collection of free online calculators available, starting with the tools people actually use every day.


What All Calculator Does

All Calculator currently offers a full scientific calculator that handles basic arithmetic, percentages, brackets, exponents, and trigonometric functions. Every calculation runs instantly in your browser. Nothing is stored, nothing is tracked, and you never need to create an account.
We are actively building dedicated calculators for specific everyday tasks, a percentage calculator, a GST calculator, a discount calculator, a bill splitter, and more. Each new calculator will launch alongside a plain-English guide explaining the maths behind it.

Who Uses All Calculator

Students use it to check homework answers and explore maths concepts without downloading an app. Office workers use it for quick calculations during meetings. Shoppers use it to verify discounts and compare unit prices. Freelancers and small business owners use it to check invoices and calculate GST.

If you need a number quickly and reliably, All Calculator is built for you.

Our Commitment

All Calculators will always be free. No subscription tiers, no paywalls, no trial periods. The calculators will always work without a login. We will continue adding new tools and improving existing ones based on what our users actually need.

If there is a calculation type you use regularly that we do not yet offer, contact us at support@allcalculator.biz and we will consider building it.
