Core Maturity Value Calculator Inputs & Terminology
The total dollar amount an investor receives when a fixed-income security or deposit reaches its contractual maturity date.
The original face amount invested or loaned at inception.
The number of times per year interest is credited to the principal (e.g. monthly n=12, daily n=365).
Simple interest calculates return strictly on the principal; compound interest earns interest on interest.
