About Bloguu
Bloguu is a collection of twenty-three free online calculators for money, health and everyday questions: loans, salary, sales tax and Zakat, body weight and fitness, grades, age and dates. You do not need an account, nothing is uploaded and you can use them as often as you like. Every calculation runs in your own browser, so the numbers you type are never sent anywhere.
Why Bloguu exists
Most calculator websites answer your question and stop there. You get a single number, with no working to check, no easy way to try a second scenario and no way to share the result. Refresh the page and it is gone.
Bloguu was built to fix those gaps. Every calculator shows the formula with your own numbers filled in, so you can check the arithmetic instead of simply trusting it. The finance tools let you compare two options side by side, because the real question is usually not what a payment will be, but which of two choices is better. Your inputs are also saved in the page address, so when you share a link, it opens with your figures already filled in.
Who runs Bloguu
Bloguu is an independent website based in Pakistan. Its calculators are built and checked by a professional who works in accounting and finance. It is not owned by a bank, lender, insurer or health company, and no calculator is designed to push you toward any product.
That background shapes how the tools work. Much of accounting is about checking numbers that someone else has produced, such as a loan schedule, a profit margin or a tax figure. The calculators here are built the way an accountant would want to check their own work: the formula is named, your figures are shown in it, and nothing is hidden behind a single answer.
How every calculator is built and checked
- Standard formulas only. Each tool uses a recognized, published method and names it on the page. For example, the EMI and mortgage calculators use the standard loan amortization formula, and the calorie calculator uses the Mifflin-St Jeor equation. The body fat calculator uses the US Navy tape method, and the Zakat calculator applies 2.5% to net wealth above the silver or gold nisab.
- Tested against known results. Before a calculator goes live, its answers are compared with worked examples from the formula's source and with independent calculations.
- Health tools follow recognized guidance. Healthy ranges and cut-offs come from bodies such as the World Health Organization, and every health page explains where its measure falls short.
- Honest about limits. When a formula is known to be unreliable for some people, or when there is more than one accepted method, the page says so instead of hiding it. The GPA calculator, for example, offers both the simple CGPA to percentage method and the HEC formula.
- Reviewed when things change. Pages are checked again when a formula, guideline or tax rate they rely on is updated.
How the site is paid for
Bloguu is free to use and is supported by advertising. Ads are kept separate from the calculators and never affect a result. We do not sell your data, and the numbers you type are never sent to us, as the privacy policy explains.
The site is built with plain HTML, CSS and JavaScript, without heavy frameworks, which keeps it fast and means it can work offline once you have visited it.
Nothing here is professional advice
Everything on Bloguu is for general information and calculation only. It is not financial, tax or medical advice. The calculators apply standard formulas to the figures you enter, and they cannot know your circumstances, your commitments or your medical history.
For any decision that matters, take the result to someone qualified to interpret it. The full statement is on the disclaimer page.
Corrections
If a calculation looks wrong, please let us know through the contact page. Include the figures you entered and the answer you expected, and it will be checked and fixed.
