The calculator uses the Halifax interest formula:
Where:
Explanation: The formula calculates interest by multiplying the average daily balance by the interest rate and number of days, then dividing by 100 (to convert percentage to decimal) and 30 (standard monthly divisor).
Details: Accurate interest calculation helps credit card users understand their monthly charges, plan repayments effectively, and manage their finances better to avoid unnecessary interest accumulation.
Tips: Enter average daily balance in GBP, monthly interest rate as a percentage, and number of days in billing cycle (typically 30). All values must be positive numbers.
Q1: What is average daily balance?
A: Average daily balance is the sum of each day's ending balance divided by the number of days in the billing cycle.
Q2: How is the monthly interest rate determined?
A: The monthly rate is typically the annual percentage rate (APR) divided by 12, as specified in your Halifax credit card agreement.
Q3: Why divide by 30 in the formula?
A: The divisor 30 standardizes the calculation to a typical month, making it easier to compare interest charges across different billing cycles.
Q4: Does this formula apply to all Halifax credit cards?
A: This formula is standard for most Halifax credit cards, but specific card products may have slightly different calculation methods.
Q5: How can I reduce my credit card interest?
A: Paying your balance in full each month, making payments on time, and maintaining a lower average daily balance can help reduce interest charges.
