After investing ₹5000 monthly for 25 years with an expected return of 15% per annum, the future value of your investment would be approximately ₹1.64 crore (₹16,420,368). You can calculate the future value of your SIP (Systematic Investment Plan) using the future value formula for SIP: Where: P is the monthly investment (₹5000) r is the monthly interest rate (15% annual = 15/12/100 = 0.0125 monthly) n is the total number of months (25 years = 25 \times 12 = 300 months)
