About PaisaCalc
PaisaCalc started as the calculators one household kept in a spreadsheet: what an EMI would be at a different tenure, what a SIP grows to, what a fixed deposit pays after quarterly compounding. Putting them on a page with the formula beside the result seemed more useful than another app.
Every tool page has a worked example with real numbers, the assumptions the formula makes, and the cases where a bank's figure will differ from ours (rounding, day-count, fees).
Who runs it
PaisaCalc is published by ABSU Mobilities, a proprietorship of Sumaiya Fatima in Hyderabad, India. The same publisher runs the other ABSU sites. There is no company behind the name beyond that, and no investors.
How the tools are made
Each tool is a small program that runs in your browser. The formula is written out on the tool's page with a worked example, so you can check it by hand. Where a tool depends on a published rate, slab or table, the page names the source and the date we read it. When a source changes, the page is updated and the date moves.
Mistakes
If a result is wrong, or a source is out of date, write to support@abdulsfresh.in with the tool's name and the inputs you used. Corrections are made on the page, with the date.
