About AlarmDaddy

AlarmDaddy is a free online calculator hub built by the eDarpan group. We focus on calculators that Indians use most often — home and car loan EMIs, SIP and FD returns, income tax under both regimes, GST, salary in-hand, BMI, age and more.

Every calculator runs entirely in your browser. We never see your numbers. Results are instant, the math is transparent, and every tool comes with a written explanation so you understand the answer — not just see it.
