About Us
Brainulator is a free collection of simple, specific online calculators for everyday questions that general calculators don’t answer well.
What we build
Instead of one broad “loan calculator”, we build focused tools: instalment calculators for specific banks and vehicles, pregnancy and due-date calculators for different animals, calorie calculators for popular food chains, home repair cost estimators, student loan tools and more. Each calculator comes with a plain-English guide that explains how it works, shows a worked example and answers common questions.
How we make our calculators
- Each calculator is based on a published formula or an official source, such as a bank’s own terms, a university extension service or a brand’s official nutrition information. We name the source on the page.
- We test each calculator with worked examples before it goes live.
- Most calculators run entirely in your browser, so the values you type are not stored.
- When a figure can change, such as a bank’s rate, we say so and point you to the official source.
Who it’s for
Our visitors are mostly from India, Pakistan and the United States: farmers and livestock owners, car and bike buyers, students, parents and anyone who wants a quick, clear answer on their phone.
