FAQs
Does this include extra deposits or interim withdrawals?
Use the cash-flow assumptions actually represented by the fields. A projection without those transactions should not be treated as modelling an account with changing deposits and withdrawals.
Which inputs do I need for Compound Interest Calculator (Yearly, Half-Yearly, Quarterly, Monthly)?
Use Principal Amount (₹); Annual Interest Rate (% p.a.); Time Period (Years); Compounding Frequency. The built-in examples show how those fields fit together.
What should I check before using this result?
Assumes no interim withdrawals during the compounding horizon. Check current official rules and your own circumstances before making a filing or financial decision.
