Tips: Enter the principal amount in dollars, annual interest rate as a percentage, and the number of days. All values must be positive numbers.
Q1: What's the difference between simple interest and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on both the principal and accumulated interest.
Q2: Why use 365 days instead of 360?
A: Using 365 days provides a more accurate calculation for actual daily interest, though some financial institutions may use 360 days for simplicity.
Q3: Can this calculator be used for any currency?
A: Yes, the calculation works for any currency as long as you're consistent with the principal amount input.
Q4: How accurate is daily simple interest calculation?
A: It provides precise interest calculation for the exact number of days, making it more accurate than monthly calculations for short periods.
Q5: Does this work for leap years?
A: This calculator uses 365 days for standardization. For leap year calculations, you would need to use 366 days specifically for leap years.
