The Eighth Wonder of the World
Albert Einstein supposedly called compound interest the eighth wonder of the world. But most people only focus on the interest rate, ignoring the equally important variable: Compounding Frequency.
What is Compounding Frequency?
This is how often the interest you've earned is added back into your principal to start earning interest itself. The more frequently this happens, the faster your money grows.
The Math: $10k at 10% for 10 Years
- Annual: $25,937
- Monthly: $27,070
- Daily: $27,179
The jump from annual to monthly is significant ($1,133 difference!), while the jump from monthly to daily is smaller but still meaningful.
Why It Matters for Your Bank Account
High-yield savings accounts typically compound daily, while most CDs compound monthly. When comparing two financial products with the same APR, always check the compounding frequency; the one that compounds more often will always have a higher APY (Annual Percentage Yield).
Conclusion
Small percentages, repeated often, lead to massive wealth. Use our Compound Interest tool to see how different frequencies impact your long-term growth.
