This calculator enables users to compute the interest accrued on loans or investments, using the Bankers Rule, which is based on a 360-day year. This method simplifies the calculation of interest for varying loan terms, making it a preferred choice for many financial institutions and individuals for its ease and adaptability.
Formula of Bankers Rule Interest Calculator
The formula to calculate interest using the Bankers Rule involves a few simple steps:
- Convert the Annual Interest Rate to a Decimal:
- Rate = Annual Interest Rate / 100
- Calculate the Interest:
- Interest = (Principal * Rate * Time) / 360
Where:
- Principal: The initial amount of money invested or borrowed.
- Rate: The annual interest rate as a decimal.
- Time: The number of days the money is invested or borrowed.
This formula provides a quick way to calculate the interest accruing on a sum over a specified period based on a standardized 360-day year, which simplifies interest calculation across different periods.

Example of Bankers Rule Interest Calculator
For instance, if you invest $10,000 at an annual interest rate of 5% for 90 days, using the Bankers Rule Interest Calculator, the interest would be calculated as follows:
- Rate = 5 / 100 = 0.05
- Interest = ($10,000 * 0.05 * 90) / 360 = $125
This calculation shows that $125 will be accrued in interest over the 90 days under these conditions.
Most Common FAQs
The 360-day year simplifies the arithmetic by aligning months with even 30-day periods, facilitating easier and more consistent interest calculations across various terms and conditions.
While widely applicable, it is best use for short-term loans or investments where daily interest calculations are prefer for simplicity.
Using a 360-day year might slightly increase the interest rate per day, potentially leading to higher total interest paid over the same period compared to calculations based on a 365-day year.
