How Compounding works

Time, return and ongoing contributions drive the result. The path is not smooth in market-linked investments, and a projected rate is an assumption rather than a promise.

A rupee example

₹1 lakh growing at an assumed 10% annually becomes about ₹1.61 lakh after five years because later returns apply to earlier gains too.

The example isolates one idea so the arithmetic is visible. Real outcomes can include taxes, fees, cash-flow timing and market movement that the simplified example does not model.

Why it matters for your family

Starting early helps, but cost and tax also compound in the opposite direction. Compare projections with conservative assumptions and real goal dates.
