# Simple Interest Loan Calculator - NASD 360

Calculates the total debt for a simple annual interest loan for the days between dates based on the US/NASD 360 method.

Loan: The loan amount.

i% : The annual interest rate entered as a percent.

DateS: The start date in YYYYMMDD format.

DateE: The end date in YYYYMMDD format.

### Date Entry

CALC 1 uses the ISO 8601 YYYYMMDD format for entering dates. This is a common date format that most users around the world are familiar with.

For example, April 28, 2004 is entered as 40428. June 4, 2018 is entered as 180604.

### Date Entry Shortcuts

If you omit the first two years (the century) of YYYY, CALC 1 will use the current century, 20. This is a common truncated representation.

If you omit the entire YYYY, CALC 1 will use the current year.

## Example 1

Calculate the total debt for a 4,000 loan at 6% for that starts 2011-01-05 and is due 2011-07-31.
