HisabTools is a free collection of 19 online calculators and everyday tools built for people in India. “Hisab” means calculation or account-keeping in Gujarati and Hindi – and that is exactly what we help with: loan EMIs, SIP returns, GST, percentages, age, dates, unit and currency conversions, amounts in words for cheques, passwords, QR codes and text counting.
Why we built it
Most calculator websites are crowded with pop-ups, ask for sign-ups or only work in English. We wanted a fast, clean and trustworthy place where anyone – a student, a shopkeeper, a salaried employee or a small business owner – can get the right answer in a few seconds, in the language they are most comfortable with.
What makes HisabTools different
- Three languages. Every tool and guide is available in English, ગુજરાતી (Gujarati) and हिन्दी (Hindi).
- Transparent maths. Each tool explains the formula it uses and walks through a worked example, so you can verify the result.
- Private by design. Calculations run inside your browser. We do not upload or store the numbers or text you type.
- Made for India. Rupee formatting, lakh and crore, GST slabs, UPI QR codes and units such as tola and guntha.
- Free forever. No sign-up and no usage limits. The site is supported by advertising.
How we check accuracy
Our calculations use standard, published formulas – for example the reducing-balance EMI formula used by Indian banks and the annuity formula used for SIP projections. Every calculation engine is covered by automated tests that compare results against worked examples. We review our content and rates information regularly and update it when rules change, such as GST rate revisions.
Even so, our tools give estimates for general information. For decisions about loans, investments, taxes or health, please confirm with your bank, a qualified financial or tax advisor, or a doctor. Read our disclaimer for details.
Who is behind HisabTools
HisabTools is built and maintained by DevNestTech, an independent software studio in India. We design and test every tool ourselves.
