Saikat RoyHisabBD
Free English & Bangla calculators for everyday life in Bangladesh, covering loans, VAT, savings, exam GPA, land units and more. Everything runs in the browser, so nothing you type leaves your device.
Overview
What it is
HisabBD is a set of 40+ free online calculators built for Bangladesh, in English and Bangla. It covers everyday questions such as loans (EMI), VAT, savings (Sanchayapatra, DPS, FDR), salary, land units, exam results (SSC/HSC GPA and CGPA), age and BMI.
It is a static, client-side site with no backend, database or paid APIs. Calculator inputs stay in the browser; the only thing stored is an optional calculation history, which can be turned off or cleared.
Every calculator has its own page, grouped into categories and searchable, with Bangla versions generated automatically. It is tested with Vitest and Playwright and deployed on Vercel.
