Simple interest calculator 

This tool calculates how much interest will be charged on the principal only (initial amount that you invested) at
certain interest rate for particular period of time.
Simple interest calculations ignores the effects of compounding, so interest on interest is not included.
It can be calculated using the following equation: FV = P + I I = P * R * T where: FV = Future value I = Interest amount P = Principal amount R = Interest rate (as a decimal, not in percentage) T = Time period Example 1: The US federal government issued the following Treasury Notes (Tnotes): $1000 Tnote with a 3% annual rate, paid quartely, with a maturity in 5 years. Question: If you obtain a $1000 Tnote how much interest will you earn and what is your future value? Interest amount I = 1000 * 0.03 * (4*5) = $600 Future value FV = 1000 + 600 = $1600 Example 2: Jim borrowed $2000 for 1.5 years at 0.1% per week simple interest. Question: How much interest is he charged and what is the total amount he has to pay back? Interest amount I = 2000 * 0.001 * (1.5 * 52) = $156 Total return amount FV = 2000 + 156 = $2156 This simple interest calculator has many features:
