The formula to calculate the Doubling Time (Simple Interest) (DTSI) is:
\[ DTSI = \frac{100}{%i} \]
Where:
Doubling Time (Simple Interest) is used to calculate how long it would take to double the balance on an interest-bearing account that has a simple interest.
Annual Interest Rate is the amount charged, expressed as a percentage of principal, by a lender to a borrower for the use of assets on an annual basis.
Let's assume the following value:
Using the formula:
\[ DTSI = \frac{100}{%i} \]
Evaluating:
\[ DTSI = \frac{100}{7} \]
The Doubling Time (Simple Interest) is 14.2857142857143 years.
