1. What is the I Bond Calculator 2023?

The I Bond Calculator 2023 calculates the current value of Series I savings bonds purchased in 2023, taking into account both fixed and inflation-adjusted components of the bond's composite rate.

2. How Does the Calculator Work?

The calculator uses the I Bond value formula:

\[ V = P \times (1 + \frac{fixed + 2 \times inflation + fixed \times inflation}{2})^{2 \times y} \]

Where:

$ V $ — Current value of the bond (USD)
$ P $ — Purchase amount (USD)
$ fixed $ — Fixed annual rate (decimal)
$ inflation $ — Semiannual inflation rate (decimal)
$ y $ — Years held (years)

Explanation: The formula combines the fixed rate with twice the semiannual inflation rate plus their product, divided by 2, then compounds this rate semiannually over the holding period.

3. Importance of I Bond Valuation

Details: Accurate I Bond valuation helps investors understand the real return on their investment, especially important for bonds with inflation protection features in changing economic conditions.

4. Using the Calculator

Tips: Enter purchase amount in USD, fixed annual rate and inflation rate as decimals (e.g., 0.05 for 5%), and years held. All values must be valid (positive amounts).
