How Does a SIP Calculator Work?
A Systematic Investment Plan (SIP) allows you to invest a fixed amount in mutual funds at regular intervals. This SIP calculator helps you estimate the wealth gain and expected returns for your periodic monthly investment based on a projected annual return rate.
The calculation uses the formula for Future Value of an Annuity Due :
FV = P × [({1 + r}^n – 1) / r] × (1 + r)
P: Monthly investment amountr: Monthly rate of interest (Annual Rate / 12 / 100)n: Total number of months (Years × 12)
Example Calculation
Suppose you invest $500 per month for 10 years at an expected annual return of 12% .
Total Invested: $60,000Wealth Gained: $56,169Total Value: $116,169
Benefits of SIP Investing
Investing via SIP offers several advantages over lump-sum investments, especially for long-term wealth creation:
Rupee Cost Averaging: You buy more units when prices are low and fewer units when prices are high, averaging out your cost.Power of Compounding: Small amounts invested early grow exponentially over time.Financial Discipline: It automates your savings and makes investing a monthly habit.
