A: No, this simple calculation doesn't account for compounding. For APR/APY, more complex formulas are needed.

Q2: When is this simple conversion appropriate?
A: When interest doesn't compound, or for quick estimates before using more precise formulas.

Q3: How do I convert percentage to decimal?
A: Divide the percentage by 100 (e.g., 5% = 0.05).

Q4: What's the difference between nominal and effective annual rate?
A: The nominal rate ignores compounding, while effective rate includes compounding effects.

Q5: Can I use this for daily rates?
A: No, this is specifically for monthly to annual conversion. For daily rates, you'd multiply by 365.
