Maturity Value Calculator

What maturity value means for deposits and investments

Maturity value is the total amount you receive when a fixed-term investment ends. It includes your original principal plus all interest earned over the holding period. Banks quote maturity values on certificates of deposit, fixed deposits, and bonds. Investors use the same concept to project how a lump-sum grows before withdrawals begin.

This calculator supports both simple and compound interest. For bank-style term deposits with payout schedules and effective annual yield, compare results with our fixed deposit calculator or CD calculator. If you plan to add monthly contributions on top of a starting balance, model the full growth path with our compound interest calculator.

Maturity value formulas

Under simple interest, earnings accrue only on the original principal each year:

Under compound interest, each period's earnings are added to the balance and earn interest themselves:

Here, $P$ is principal, $r$ is the annual rate as a decimal, $t$ is time in years, and $n$ is compounding periods per year. Total interest equals $MV - P$.

Worked example (compound, monthly)

A $10,000 deposit at 6.5% annual interest for 5 years compounded monthly uses $n = 12$ and $t = 5$. The maturity value is approximately $13,828.17, of which $3,828.17 is interest. Monthly compounding earns more than annual compounding on the same nominal rate because interest is credited twelve times per year.
