I = (P x T x R)/100
You need to know the principal amount, the rate and the time. Then a very simply formula for calculating interest is I = PRT where P is the principal amount, R is the interest rate and T is the period of time in years.
I = P X R X T
time= interest/principal x rate likee yeahh thats it
(Face Value of Note) x (Annual Interest Rate) x (Time in Terms of One Year) = Interest
The formula for the daily compound interest is B=p(1+r over n)NT as an exponent for the nt B= ending balance P= principal amound r= interest rate n= number of compounds per year t= time( in years)
formula
I = PRT where I is the interest. P is the principal R is the interest rate per unit of time, expressed as a fraction (5% = 0.05 or 1/20) but not as a percentage, T is the number of time units.
the formula for simple interest is I=PRT (interest=principal x rate x time )
It depends on whether it is simple or compound interest. The formula for simple interest is A = P(1+rt), where A = amount of money after t years, P = Principal, or the amount of money you started with, and r = the annual interest rate, expressed as a decimal (i.e. 7% = 0.07). For compound interest, the formula is A = P(1+r)t.
i=prt FACT: If an annual interest rate is given, time in the simple interest formula must be expressed in terms of years.
time
I = prt where I = interest, p = principal, r = rate. and t = time in years.
I= Prt I=interest P=principal r=rate t=time
You need to know the principal amount, the rate and the time. Then a very simply formula for calculating interest is I = PRT where P is the principal amount, R is the interest rate and T is the period of time in years.
P*(1+R/100)powerT where P= money borrowed or principal and R= rate in percent and T= time * * * * * Actually, this formula gives the value of the principal PLUS interest. You need to subtract P from the answer to get the compounded interest.
The formula for simple interest is Interest = Principal x Rate x Time ÷ 100 As the rate is an annual rate and the period is 1 year then Interest = Principal x 4.5/100. The balance at the year end = Principal + Interest = Principal x 104.5/100.
I = P X R X T
