About Interest Khata
Interest Khata makes free interest calculators for India that work the way people really lend and borrow: in rupaye sekda, counted in months and days, with every step shown.
Why we built it
Most interest calculators online are built for bank deposits and EMIs, in % a year. But a great deal of lending in India, between friends and relatives, shopkeepers and customers, traders and farmers, is counted in rupaye sekda for months and days, the way a bahi does. When two people work it out differently, the hisaab turns into an argument.
So we built calculators that speak that language, give the exact answer to the paisa, and show the working, so both sides can check it. The same tools also turn a bank’s EMI into the simple-interest rate people think in.

How we work

- Open. Every result shows its working, so you never have to take our word for it.
- Private. Calculations run in your browser and nothing you type is sent to us. We count visits with Google Analytics, which sees only the page’s address, never your numbers.
- Independent. We don’t lend money, don’t take money from lenders to rank them, and don’t show loan ads.
- Checked. Guides that mention laws or RBI rules link to the original source and show the date they were last checked.
