The maturity value is the total amount you receive when a bond, certificate of deposit, or fixed-term investment reaches its maturity date — your original principal plus all accumulated interest.
When you invest in a fixed-rate instrument, the maturity value tells you exactly how much you will receive at the end of the term. It combines the return of your principal with the compounded interest earned over the holding period.
For bonds, the maturity value is typically the face value (assuming par redemption) plus the final coupon. For deposits and CDs, it is the principal grown by compound interest.
The standard compound interest formula calculates the future value.
MV = P × (1 + r/n)^(n×t)
P = principal, r = annual rate (decimal), n = compoundings per year, t = years.
Invest 10,000 at 5% annual compounding for 5 years. MV = 10,000 × (1.05)^5 = 12,762.82. Total interest earned: 2,762.82.
Assumes a fixed rate for the full term. Does not model early withdrawal penalties, variable rates, or reinvestment of intermediate coupon payments.
Frequently asked questions
Yes. More frequent compounding (monthly vs annual) produces a slightly higher maturity value because interest earns interest sooner. The difference grows with longer terms and higher rates.
For a single deposit with no withdrawals, yes. Maturity value and future value are the same concept — the amount at the end of the term.
This calculator shows the gross maturity value before taxes. Interest income is typically taxable in the year earned (for accrual-basis instruments) or at maturity (for some zero-coupon instruments). Consult a tax professional.
Early withdrawal from CDs usually incurs a penalty (often several months of interest). Bonds sold before maturity trade at market price, which may be above or below face value.
