Your Free Calculator Hub

Totu Calculator is happy to be developing more and more efficiency-boosting calculators that bring value to people. We search far and wide for calculators that users are looking to use and try to bring them the best version of them as possible.

Totu is developing a collection of accessible, easy-to-use, mobile-friendly, and accurate calculators.

Free To Use

Totu Calculator is dedicated to being free to use as we feel information and calculations are for everyone, there is no need to charge users for this type of information.

Mobile-Friendly

We understand you may not always be behind a PC or laptop screen, that is why we made all of our calculators usable and perfectly displayed on mobile devices, including tablets.

Unique Solutions

While we want to assist with the most common questions and equations, we develop calculators that reach a certain niche, just so no one is left out without any help.

Vast Calculator Catalog

While we currently are only offering a few dozens calculators, the goal with this project will be to deliver hundreds of differently categorized calculators, still for free.

Open Communication

We love to hear from our user-base, reach out to us with calculator requests, UI/UX recommendations, or any other question, comment, or concern you may have.

Frequent Updates

Not only is the Totu Calculator team constantly adding to the current calculator catalog, we are editing old ones to revise them if any changes arise in the formulas or expanding on them.
