Definition
The Banker’s Year is a financial convention used to standardize the length of a month at 30 days and the length of a year at 360 days, as opposed to the actual 365 or 366 days in a calendar year. This standardized measure is used to simplify the calculation of interest, prorated expenses, and other financial computations in lending and financial transactions.
Examples
Example 1: Loan Interest Calculation
A loan agreement states that annual interest on a $100,000 loan is calculated based on a 360-day year. If the interest rate is 5%, the daily interest rate would be:
\[ \text{Daily Interest Rate} = \frac{5%}{360} = 0.0139% \]
For 30 days of interest calculation, this would be:
\[ \text{Thirty-day Interest} = $100,000 \times \frac{5%}{12} = $416.67 \]
Example 2: Prorated Expenses
Suppose a property incurs an annual property tax of $18,000. Using the Banker’s Year convention, if a sale happens on the 120th day of the year:
\[ \text{Daily Expense} = \frac{$18,000}{360} = $50 \] \[ \text{Seller’s Responsibility} = 120 \times $50 = $6,000 \]
The seller is responsible for $6,000, which is one-third of the annual property tax.
