What the finance tools cover
The finance section is built around three families. Loan calculators (EMI, home loan, car loan, personal loan and the rest) all amortise on a reducing balance, which is how banks actually charge interest and why the first instalments are mostly interest. Investment calculators (SIP, compound interest, fixed deposit, CAGR) use the future-value identities that the products themselves are priced with. Tax tools (income tax, GST, HRA) follow the published slab and rate rules, with the Indian new-versus-old regime comparison built in.
Every page states the formula it uses and works one example from its default values, so you can check the arithmetic by hand. Fees, processing charges and lender rounding are not modelled unless there is a field for them, and rates are treated as fixed for the whole term. A floating-rate loan will drift from the schedule shown here.
Where to start
- Comparing two loan offers: run both through the loan calculator and compare total interest, not the monthly figure.
- Planning a monthly investment: the SIP calculator shows how much of the final corpus is your own money and how much is growth.
- Deciding between tax regimes: the income tax calculator computes both side by side from one set of inputs.
- Checking a quoted rate: the simple interest and compound interest pages make the flat-rate trick visible.
Nothing you enter leaves your browser. That matters more here than in most categories, because the inputs are your salary, debts and savings.
