Categories at a Glance
SIP & Mutual Funds covers building wealth through markets over time — regular monthly investing, systematic withdrawals in retirement, and working backward from a goal to the return you'd need. Government Savings Schemes covers PPF, Sukanya Samriddhi Yojana, and Kisan Vikas Patra — guaranteed, government-backed instruments where the return is fixed by policy rather than the market. Retirement & Pension covers the National Pension System (including a dedicated NPS vs Unified Pension Scheme comparison for government employees), a side-by-side comparison of every major Indian pension option, and the SBI/post office Annuity Deposit Scheme. Insurance covers LIC's two main product types: pure protection term cover and endowment plans that combine insurance with a maturity payout. Stocks & Trading is for active equity investors — averaging into a falling position correctly and knowing your real, all-in trading costs before you place an order. Salary & Payroll has one focused tool: turning a CTC offer into the number that actually lands in your bank account each month. Gold has one tool as well, built to test a common assumption — whether gold has actually kept up with inflation over any given period, rather than assuming it always does. Financial Planning covers the fundamentals that come before any product choice: how large an emergency fund you actually need, and what a past investment would be worth today across asset classes.

How This Directory Is Kept Up to Date
Every calculator listed here is checked against the current official rate or rule before publishing — Government of India small savings rates for PPF, SSY, and KVP; the latest income tax slabs and EPF/ESI thresholds; and real broker pricing for trading tools. When a rate or rule changes, such as a quarterly PPF rate reset or a new tax slab, we revisit the affected calculator directly rather than leaving stale figures in place. New calculators are added based on what Indian investors are actually searching for, and each one goes through the same accuracy and mobile-responsiveness checks before it's added to this page. The "New" badge above marks anything published within the last few days, so returning visitors can spot what's changed since their last visit without re-reading the whole directory.
