What is Compound Interest?
Compound Interest (CI) is the interest calculated on the initial principal and also on the accumulated interest from previous periods. Unlike simple interest, compound interest grows exponentially because you earn "interest on interest." It is the most common method used in savings accounts, fixed deposits, and mutual funds.
Benefits of Compound Interest
- Exponential Growth: Your money grows faster over time as interest earns more interest.
- Power of Time: The longer the investment period, the greater the compounding effect.
- Wealth Building: Compound interest is the key principle behind long-term wealth accumulation through SIP and other investments.
- Flexible Compounding: Choose between monthly, quarterly, half-yearly, or yearly compounding to match your investment type.
- Universal Application: Used in FDs, savings accounts, mutual funds, bonds, and more.
Calculation Formula
A = P × (1 + r/n)n×t
CI = A − P
Where:
- P = Principal amount
- r = Annual interest rate (in decimal)
- n = Number of times interest is compounded per year
- t = Time period in years
- A = Final amount
