CD Interest Calculator Compounded Monthly: Why It Matters
Monthly compounding means that you get a return on your investment every month. This means your money grows faster. The more times the compounding occurs, the higher the return.
Pros of Monthly Compounding:
• Faster profits
• Higher earnings in the same period
Cons:
• Calculations are a bit complicated (which our tool makes easy!)
Real-Life Example
Let’s say two friends:
• Anna invested $5,000 at 3% for 5 years, compounding annually.
• Ben invested the same amount and rate, but compounding monthly.
According to our calculator:
• Anna earns: $796.37
• Ben earns: $807.17
Ben earns $10.80 more just by choosing monthly compounding. What if the same amount was $50,000?
