Simple Interest Calculator
Simple interest is calculated by multiplying the rate of interest by the principal and duration
Principal Amount: 100
Interest Rate : 10%
Duration : 1 Years
Total AMOUNT : 110
FINAL AMOUNT : 110.00
Simple Interest Formula
Find Interest Amount with Principal, Interest Rate and Time
Interest = P x T x R / 100
P is Prinicipal
R= interest rate / annum
T = time in years
Final Amount using Principal, Interest Rate and Time
SI = P * ( 1 + RT)
P is Prinicipal
SI = Simple Interest Final Amount
R= interest rate / annum
T = time in years
Find Principal with Final Amount, Interest Rate and Time
P = SI / (1 + RT)
Find Interest Rate with Principal, Final Amount and Time
R = (1 / T) (A / P - 1)
Find Time / Duration given Principal , Final Amount and Rate
T = (1 / R) (A / P - 1)

Calculate the Simple Interest if the principal amount is Rs. 10,000, the time period is 5 year and the rate is 3.875%. Simple Interest, SI = P(1 + rt). r = R / 100 = 3.875 % / 100 = 0.03875 per year. A = 10000(1 + (0.03875 × 5)) , A = Rs. 11,937.50
