Example of Using a Saving Bond Calculator
Example Scenario
- Face Value: $1,000
- Issue Date: January 1, 2015
- Interest Rate: 2% per year
- Maturity: 20 years
Step-by-Step Calculation
- Calculate years held: 2026 – 2015 = 11 years
- Calculate future value:
FV=1000×(1+0.02)11≈1000×1.243=1243
- Calculate interest earned:
Interest=1243−1000=243
Result
- Current Value: $1,243
