1. What is the Daily Balance Method?

The Daily Balance Method is a common way to calculate interest on loans or credit accounts. It sums the interest calculated on each day's balance over the billing period, providing a precise interest calculation that accounts for daily fluctuations in the account balance.

2. How Does the Calculator Work?

The calculator uses the Daily Balance formula:

Where:

• Daily Balance — The account balance each day
• Daily Rate — Annual rate divided by 365 days
• 365 — Number of days in a year (some institutions use 360)

Explanation: The method calculates interest for each day based on that day's balance, then sums all the daily interest amounts for the total interest charge.

3. Importance of Daily Balance Calculation

Details: This method is commonly used by credit card companies and banks because it provides the most accurate reflection of actual account usage. It benefits lenders when balances fluctuate, as it captures interest on every dollar for every day it's borrowed.

4. Using the Calculator

Tips:

• Enter daily balances as comma-separated values (e.g., "1000, 1050, 950")
• If you provide fewer balances than days, the last balance will be carried forward
• Enter the annual interest rate as a percentage (e.g., 18.99)
• Specify the total number of days in the billing period

5. Frequently Asked Questions (FAQ)

Q1: How does this differ from average daily balance?
A: The daily balance method calculates interest on each day's actual balance, while average daily balance uses the average of all daily balances in the period.

Q2: Do all credit cards use this method?
A: Most use either daily balance or average daily balance methods. Check your card agreement for specifics.

Q3: Why is my calculated interest different from my statement?
A: Some institutions use 360 days instead of 365, or may have minimum finance charges or other fees.

Q4: How can I reduce interest with this method?
A: Making payments earlier in the billing cycle reduces your daily balances, thereby reducing interest.

Q5: Is this method better for consumers?
A: Generally no - it tends to calculate slightly higher interest than average daily balance method when balances fluctuate.
