Simple Interest Calculator
Simple interest is calculated by multiplying the rate of interest by the principal and duration
Principal Amount: 5000
Interest Rate : 7%
Duration (Years): 1
Total Amount : 5350
Interest Amount : 350.00
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)

Generally, simple interest is set as a fixed percentage for the duration of a loan.
Calculate Total Amount (Principal + Interest).
A = P(1 + rt)
SI = P * ( 1 + RT).
P is Prinicipal, SI = Simple Interest Final Amount, R = interest rate / annum, T = time in years .
Simple interest is calculated based on the principal, or original, amount of a loan.
Compound interest is calculated on the principal amount and the interest of period of time.
R = (1 / T) (A / P - 1).
R = Interest Rate, P is Prinicipal, A = Final Amount, T = time in years .
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
P = SI / (1 + RT).
P is Prinicipal, SI = Simple Interest Final Amount, R = Interest Rate, T = time in years .
