Understanding Compound Interest
Compound interest means you earn interest not only on your original investment but also on accumulated interest.
For example:
If you invest $1,000 at 5% annually:
- Year 1: $1,050
- Year 2: $1,102.50
- Year 3: $1,157.63
Over time, growth accelerates significantly.
This calculator automatically applies compound growth over the number of years you enter.
Tips for Maximizing Bond Returns

- Compare interest rates before purchasing
- Avoid early redemption penalties
- Reinvest earnings strategically
- Diversify across investment types
Savings bonds work best as part of a balanced portfolio.
Are Savings Bonds Safe?
Savings bonds issued by national governments are generally considered very safe investments because they are backed by the government’s credit.
However, keep in mind:
- Returns may not beat inflation
- Interest rates can vary
- Early withdrawal penalties may apply
Always review official terms before investing.
