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
FV = Future value
I = Interest amount
P = Principal amount
R = Interest rate (as a decimal, not in percentage)
T = Time period
The US federal government issued the following Treasury Notes (T-notes):
$1000 T-note with a 3% annual rate, paid quartely, with a maturity in 5 years.
If you obtain a $1000 T-note 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
Jim borrowed $2000 for 1.5 years at 0.1% per week simple interest.
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
