Who I am

I am Aniket Nigam, an independent software engineer based in India. CalcCrack is a side project I started because I was tired of opening Indian bank and comparison sites only to hit a wall of phone-number capture forms before I could see an EMI number. Every calculator here is free, runs in the browser, and never asks for a phone number or email to produce a result.

What I am not

I am not a Chartered Accountant, a SEBI-registered investment advisor, or an IRDAI-licensed insurance broker. I do not sell loans, insurance policies, mutual fund units, or portfolio management services. Nothing on CalcCrack should be interpreted as personal financial, tax, investment, or insurance advice.

CalcCrack's calculators implement formulas directly from published Indian regulatory material: the Income Tax Act 1961 and subsequent Finance Acts, the Public Provident Fund Scheme Rules 2019 (Gazette of India), the National Pension System regulations administered by PFRDA and NSDL, the Sukanya Samriddhi Account Scheme Rules, and published Reserve Bank of India circulars on repo rate, MCLR, and external benchmark linked lending rates. For specific financial decisions, consult a licensed professional in your jurisdiction.

Why I built CalcCrack

I was trying to compare two home loan offers in 2024. The first calculator asked for my phone number before showing me the EMI. The second asked for my PAN. The third showed an EMI but did not tell me which interest rate convention it used, how prepayment was modelled, or whether the rate included processing fees.

That frustration is the reason CalcCrack exists. Every calculator on the site follows four rules: the formula is printed on the page, the source is cited with a link to the actual regulation or bank rate sheet, no personal data is required, and the result is produced client-side so nothing about your calculation leaves your browser.

How calculators are built

For each calculator I start with the primary document. For income tax I read the relevant Finance Act and CBDT notifications. For PPF I reference the PPF Scheme Rules 2019 notification. For NPS I reference the PFRDA regulations and NSDL scheme documents. For EMI and home loans I use the standard amortisation formula with rates cross-checked against the lender's published MCLR or RLLR rate sheet on the day of review. The full methodology, including how often rates are reviewed and which sources are used, is documented on the methodology page.
