Since the principal compound interest is best defined as P is simply a coefficient, it is often dropped for simplicity, and the resulting accumulation function is used instead.

Given an principal deposit and a recurring deposit, the total return of an investment can be calculated via the compound interest gained per unit of time. If required, the interest on additional non-recurring and recurring deposits can also be defined within the same formula . The interest on loans and mortgages that are amortized—that is, have a smooth monthly payment until the loan has been paid off—is often compounded monthly.
