-------------------------------------

Compound interest grows your money exponentially because each period's interest is added back to the principal, which then earns interest in the next period too. The standard formula used is:

 A = P × (1 + r/n)n×t **A** — Maturity amount **P** — Principal invested **r** — Annual interest rate (decimal) **n** — Compounding frequency per year **t** — Time period in years If you also invest a fixed amount every month, this calculator adds the future value of those monthly contributions on top of the lump sum maturity value to give you the combined wealth estimate.

  Why Compounding Matters
------------------------

### Exponential Growth

Interest earns interest, so your wealth grows faster the longer you stay invested — not in a straight line, but a curve.

### Time Is Your Biggest Asset

Starting early matters more than investing a large amount — a longer time horizon lets compounding do the heavy lifting.

### Lump Sum + SIP Together

Combining a one-time investment with disciplined monthly top-ups accelerates your goal-based wealth creation.

  Frequently Asked Questions
---------------------------

 What is compound interest? Compound interest is interest calculated on the principal plus all previously accumulated interest, allowing your money to grow faster than simple interest. How is it different from simple interest? Simple interest is earned only on the original principal, so it grows linearly. Compound interest earns on both principal and accumulated interest, so it grows exponentially. Which compounding frequency gives higher returns? For the same nominal rate, more frequent compounding — daily or monthly — yields a slightly higher maturity value than annual compounding. Can I use this for SIP-style investing? Yes — use the optional monthly top-up field to estimate combined growth of a lump sum plus regular monthly contributions, similar to an SIP. Does compounding really make a big difference long term? Absolutely. The longer your investment horizon, the more dramatic the compounding effect — small differences in time can lead to large differences in final wealth.
