1. What is the US Savings Bonds Current Value Formula?

The US Savings Bonds Current Value formula calculates the current worth of a savings bond based on the purchase amount, annual interest rate, and years held. It accounts for semi-annual compounding, which is typical for US savings bonds.

2. How Does the Calculator Work?

The calculator uses the savings bonds valuation formula:

Where:

• \( V \) — Current value of the bond (USD)
• \( P \) — Original purchase amount (USD)
• \( rate \) — Annual interest rate (decimal)
• \( y \) — Number of years the bond has been held

Explanation: The formula uses semi-annual compounding (interest applied twice per year), which is why the rate is divided by 2 and the exponent is multiplied by 2.

3. Importance of Savings Bonds Valuation

Details: Accurate valuation of savings bonds is essential for financial planning, tax reporting, and understanding the growth of your investments over time.

4. Using the Calculator

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 held. All values must be positive numbers.
