How It Works (Formula & Method)
This calculator takes Deposit ($), APY (%), Term (months), and Compounds/Year as input and computes Maturity Value and Total Interest. The math runs entirely in your browser the moment you change a value — nothing is sent to a server, and your inputs are never stored.
The formula used is the standard financial calculation for this metric. For a full step-by-step derivation with the default values, see the Worked Example section below.
