The calculator uses the daily interest formula:
Where:
Explanation: The formula converts the annual interest rate to a daily rate by dividing by 365 days, then multiplies by the current balance to determine daily interest earnings.
Details: Understanding daily interest helps savers track earnings growth, compare different savings products, and make informed financial decisions about where to keep their money for optimal returns.
Tips: Enter your current account balance in dollars and the annual interest rate as a percentage. Both values must be positive numbers for accurate calculation.
Q1: Why divide by 365 instead of 360?
A: Most modern financial institutions use 365 days for daily interest calculations, though some may use 360 days. Check with your specific bank for their calculation method.
Q2: Does this account for compound interest?
A: This calculates simple daily interest. For compound interest, the calculation would need to account for interest earned on previous interest.

A: Daily interest varies by bank and account type. High-yield savings accounts might earn $0.10-$1.00 daily per $1,000 balance, depending on current rates.
Q4: How often is interest typically paid?
A: Most banks pay interest monthly, though it's calculated daily. Some accounts may offer different payment frequencies.
Q5: Can I use this for loan interest calculations?
A: Yes, the same formula applies to daily interest charges on loans, though loan rates are typically higher than savings rates.
