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)

## Frequently Asked Questions on Interest Calculator

• Simple interest is interest that is only calculated on the principal either borrowed or deposited.
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 .
