Compound Interest

How the Compound Interest works

Compound interest adds earned interest back to the base at the frequency you choose — yearly, half-yearly, quarterly, monthly or daily.

Formula / method. A = P × (1 + r/m)^(m·t). Effective annual rate = (1 + r/m)^m − 1.

When to use it. Use it when the product states a compounding frequency. A 7% annual rate compounded quarterly is not the same as 7% simple.

How to run a comparison

1. Open Compound Interest from Home search, the Finance Studio hub, or this URL.
2. Copy amounts, rates or dates from a document you already have — not a round marketing figure.
3. Read the headline result and any breakdown (schedule, slabs, or intermediate rows).
4. Change one input at a time so you can see what actually moves the answer.
5. Cross-check with a related calculator below, then confirm statutory rates before you act.
