About SIP Calculator (Systematic Investment Plan)
Our SIP Calculator accurately forecasts your accumulated corpus, showing the split between your total out-of-pocket contributions and compound investment gains over 1 to 30+ years.
Mathematical Formula & Calculation Method
M = P × [((1 + i)^n - 1) / i] × (1 + i)
Where M is the future maturity amount, P is the monthly SIP contribution, i is the periodic monthly rate of return (annual return rate ÷ 12 ÷ 100), and n is the total number of monthly payments.
