Investment Calculators

Calculators for market-linked money: monthly and one-time investments, withdrawals, and the return an investment actually earned.

Which investment calculators should you use?

These calculators split into two kinds, and mixing them up is the most common mistake people make with them. SIP, Lumpsum and CAGR deal with market-linked money, where the return is an assumption you are choosing. Bank deposits, with a contracted rate, are under FD & Savings, and government schemes such as PPF under Post Office.

For the market-linked ones, the return you type in decides the answer, so the useful exercise is not to run it once. Run it at 10%, 12% and 14% and look at how far apart the three land over twenty years. If the plan only works at the top number, it is not a plan.

SIP Calculator is for a fixed amount invested every month, and it assumes start-of-month instalments, which is how a SIP actually debits. Lumpsum Calculator is for a single amount left alone. The difference between them on the same total money is entirely about time in the market.

Use CAGR when one amount went in and one came out. As soon as money went in or out along the way, as with a SIP, CAGR misleads and XIRR is the right measure: it dates every instalment and redemption.

Compound Interest and Simple Interest show the two textbook ways a rate turns into money. Over a few years the gap is large, which is why deposits quote a compounding frequency.

SIP vs Lumpsum compares the same money invested at once or spread out. With a constant assumed return the lumpsum always ends higher; a SIP's real benefit is averaging your purchase price in a volatile market, which no constant-return calculator can show.

Inflation Calculator converts between today's rupees and tomorrow's, using official CPI and Cost Inflation Index data where they exist.

A quick sense of scale: ₹10,000 a month in a SIP for 10 years, at an assumed 12% a year, grows to about ₹23,23,391 on ₹12,00,000 invested. At 10% the same SIP ends near ₹20.7 lakh, which is why the assumed return matters more than any other input. Raising the SIP every year, as a salary rises, is modelled by Step-up SIP, and working backwards from a target amount by Goal SIP.

For tax-saving equity under the old regime, the ELSS Calculator adds the Section 80C saving and the 3-year lock-in to the growth figure. For the other end of the journey, SWP shows how long a corpus lasts with a fixed monthly withdrawal, and STP moves a lumpsum into equity in monthly steps. When you sell, the LTCG and STCG calculators work out the capital gains tax.
