Frequently Asked Questions

What is compound interest?

Compound interest is interest calculated on both the original principal and the interest already accumulated — so your money grows faster over time compared to simple interest, which is only calculated on the original principal.

What does "compounding frequency" mean?

It's how often interest is added to your principal — annually, semi-annually, quarterly, or monthly. More frequent compounding results in slightly higher returns for the same nominal annual rate, since interest starts earning interest sooner.

What's the formula used here?

A = P × (1 + r/n)^(n×t), where P is principal, r is the annual rate (as a decimal), n is the compounding frequency per year, and t is time in years.

Why does the result show a $ symbol instead of ₹?

This calculator is used worldwide, so it shows a generic currency symbol — the maths is identical regardless of currency. Just read the figures in your own currency (₹, $, £, or any other).

Is this a guarantee of investment returns?

No — this is a mathematical projection for planning purposes only. Actual returns from any real investment product depend on that product's own performance and are never guaranteed.
