FAQ Frequently Asked Questions

What is a SIP (Systematic Investment Plan)?expand
A Systematic Investment Plan (SIP) allows you to invest a fixed amount of money at regular intervals in mutual funds. It helps in rupee cost averaging and building wealth over the long term through the power of compounding.
How are SIP returns calculated?expand
SIP returns are calculated using the compound interest formula: M = P × ({[1 + i]^n - 1} / i) × (1 + i). Where M is the maturity amount, P is the monthly investment, i is the periodic rate of interest, and n is the number of months.

FAQ Frequently Asked Questions

What is a lump sum investment in mutual funds?expand
A lump sum investment is when you invest a large amount of money in a mutual fund scheme in one go, rather than breaking it up into smaller monthly installments (SIP).
Are mutual fund returns guaranteed?expand
No, mutual fund returns are subject to market risks. The expected return rate is an estimation based on historical data and future projections, but the actual returns may fluctuate.

FAQ Frequently Asked Questions

What is Compound Interest?expand
Compound interest is the addition of interest to the principal sum of a loan or deposit. In simple terms, it is "interest on interest". It makes your money grow much faster over time compared to simple interest.
How does compounding frequency affect returns?expand
The more frequently interest is compounded (e.g., daily or monthly vs. annually), the higher the total return will be. This is because the interest earned is added to the principal more often.
Simple Interest
