Calculators
Private: nothing leaves your browser
Money and dates, worked out properly and shown clearly. Find the real monthly instalment on a loan and how much of it is interest, add or remove GST at any slab, work out a percentage or a discount, or count the exact days between two dates. Each calculator shows the numbers behind the answer rather than just a total.

About these tools
The useful part of a calculator is not the total, it is the breakdown. An EMI figure on its own tells you very little; the split between principal and interest over the full term is what tells you whether a loan is worth taking.
These run in the browser and keep nothing, so the salary, loan amount or invoice value you type is never transmitted. Rates and slabs that change, like GST bands, are stated on the page so you can see exactly what the maths assumed.
Three of them show more working than the total. EMI Calculator prints the full amortisation run, so you can see the month the balance finally starts moving. GST Calculator carries the rates in force since 22 September 2025, when the 12 and 28 percent slabs were withdrawn and a 40 percent rate came in, and it still accepts an old rate typed in for checking an older invoice. SIP Calculator projects the return you choose and does not pretend the market will deliver it.
