SIP
Each monthly instalment grows at the monthly equivalent of your yearly rate (the rate ÷ 12). Instalments are assumed to be made at the start of each month.
Formula: FV = P × [(1 + i)n − 1] ÷ i × (1 + i)
P = monthly SIP, i = monthly rate, n = number of months
Example: ₹5,000 a month for 10 years is ₹6,00,000 invested. At an assumed 10% a year, the illustration comes to about ₹10.33 Lakh.
