Hisab.Bangla is a free collection of calculators built for Bangladesh, Bangla-first and also in English. Income tax, electricity bills, land units, amounts in words, age: everyday sums made simple, accurate and in your own language.
Why we built it
Most online calculators are in English, and many follow Indian rules or use rupees. Bangladesh’s tax slabs, electricity tariffs and local land units such as shotok, katha and bigha are hard to find done properly. We want to fill that gap.
How we work
- Bangladesh rules: every calculation follows Bangladesh’s laws, official orders and standard units.
- Sources and dates: values that change (tax rates, tariffs) show their source and last-checked date on the page.
- Your data stays with you: everything runs in your browser. No login, and nothing is sent to us.
- Tell us about mistakes: every calculator has a “Report a mistake” button, and we fix issues quickly.
