The Savings Bond Calculator calculates the current value of savings bonds based on the purchase amount, annual interest rate, and years held. It uses semi-annual compounding to determine the bond's worth over time.
The calculator uses the savings bond formula:
Where:
Explanation: The formula accounts for semi-annual compounding, where interest is applied twice per year, resulting in more accurate growth calculations for savings bonds.
Details: Accurate bond valuation helps investors understand the growth of their investments, plan for future financial goals, and make informed decisions about bond redemption or continued holding.
Tips: Enter the original purchase amount in USD, annual interest rate as a decimal (e.g., 0.05 for 5%), and the number of years the bond has been held. All values must be positive numbers.
Q1: What are savings bonds?
A: Savings bonds are government-issued debt securities that pay interest over time, offering a safe investment option with guaranteed returns.

Q3: What is a typical interest rate for savings bonds?
A: Rates vary by bond type and economic conditions. Recent series EE bonds have offered rates between 0.10% and 3.00% annually.
Q4: Are there penalties for early redemption?
A: Some bonds have minimum holding periods and early redemption penalties. Check specific bond terms before calculating redemption value.
Q5: How accurate is this calculator?
