The document presents interest rate information for five countries to calculate interest incurred on a 200,000 principal amount over 1 year, 5 years, 10 years, and 20 years. Singapore has the highest rate at 2.75%, while Lebanon has the lowest at 1%. The document shows the interest calculations using the formula: Amount = Principal * (1 + Interest Rate * Time). For example, interest incurred in Singapore after 1 year is 5,500, which is 200,000 * (1 + 0.0275 * 1). The document provides a table comparing the interest incurred in each country at the different time periods.
