Simple Interest Solution

STEP 0: Pre-Calculation Summary

Formula Used

Simple Interest = (Principal Amount of Simple Interest*Annual Rate of Simple Interest*Time Period of Simple Interest)/100
SI_Annual = (P_Annual*r_Annual*t_Annual)/100
This formula uses 4 Variables

Variables Used

Simple Interest - Simple Interest is the extra amount gained/paid on the principal amount for the time period at a fixed rate of interest.
Principal Amount of Simple Interest - Principal Amount of Simple Interest is the amount invested, borrowed, or lent initially at a fixed rate for a given duration of time.
Annual Rate of Simple Interest - The Annual Rate of Simple Interest is the percent of the simple interest paid over the principal amount for the due period.
Time Period of Simple Interest - (Measured in Year) - Time period of Simple Interest is the number of years for which the principal amount is invested/borrowed/lent at a fixed rate of interest.

STEP 1: Convert Input(s) to Base Unit

Principal Amount of Simple Interest: 1000 --> No Conversion Required
Annual Rate of Simple Interest: 10 --> No Conversion Required
Time Period of Simple Interest: 2 Year --> 2 Year No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SI_Annual = (P_Annual*r_Annual*t_Annual)/100 --> (1000*10*2)/100

Evaluating ... ...

SI_Annual = 200

STEP 3: Convert Result to Output's Unit

200 --> No Conversion Required

FINAL ANSWER

200 <-- Simple Interest

Simple Interest

Go Simple Interest = (Principal Amount of Simple Interest*Annual Rate of Simple Interest*Time Period of Simple Interest)/100

Simple Interest given Final Amount

Go Simple Interest = Final Amount of Simple Interest-Principal Amount of Simple Interest

< 5 Annual Simple Interest Calculators

Final Amount of Simple Interest

Go Final Amount of Simple Interest = Principal Amount of Simple Interest*(1+(Annual Rate of Simple Interest*Time Period of Simple Interest)/100)

Principal Amount of Simple Interest

Go Principal Amount of Simple Interest = (100*Simple Interest)/(Annual Rate of Simple Interest*Time Period of Simple Interest)

Annual Rate of Simple Interest

Go Annual Rate of Simple Interest = (100*Simple Interest)/(Principal Amount of Simple Interest*Time Period of Simple Interest)

Time Period of Simple Interest

Go Time Period of Simple Interest = (100*Simple Interest)/(Principal Amount of Simple Interest*Annual Rate of Simple Interest)

Simple Interest

Go Simple Interest = (Principal Amount of Simple Interest*Annual Rate of Simple Interest*Time Period of Simple Interest)/100

Simple Interest Formula

Simple Interest = (Principal Amount of Simple Interest*Annual Rate of Simple Interest*Time Period of Simple Interest)/100

What is Simple Interest?

Simple Interest is a quick and easy method of calculating the interest charge on a loan. Simple Interest is the interest amount for a particular principal amount of money at some rate of interest for given duration of time.
In Simple Interest, a creditor will only pay interest on the principal amount and a borrower would never have to pay more interest on the previously accumulated interest.

How to Calculate Simple Interest?

Simple Interest calculator uses Simple Interest = (Principal Amount of Simple Interest*Annual Rate of Simple Interest*Time Period of Simple Interest)/100 to calculate the Simple Interest, Simple Interest formula is defined as the extra amount gained/paid on the principal amount for the time period at a fixed rate of interest. Simple Interest is denoted by SI_Annual symbol.

How to calculate Simple Interest using this online calculator? To use this online calculator for Simple Interest, enter Principal Amount of Simple Interest (P_Annual), Annual Rate of Simple Interest (r_Annual) & Time Period of Simple Interest (t_Annual) and hit the calculate button. Here is how the Simple Interest calculation can be explained with given input values -> 200 = (1000*10*63113904)/100.

FAQ

What is Simple Interest?

Simple Interest formula is defined as the extra amount gained/paid on the principal amount for the time period at a fixed rate of interest and is represented as SI_Annual = (P_Annual*r_Annual*t_Annual)/100 or Simple Interest = (Principal Amount of Simple Interest*Annual Rate of Simple Interest*Time Period of Simple Interest)/100. Principal Amount of Simple Interest is the amount invested, borrowed, or lent initially at a fixed rate for a given duration of time, The Annual Rate of Simple Interest is the percent of the simple interest paid over the principal amount for the due period & Time period of Simple Interest is the number of years for which the principal amount is invested/borrowed/lent at a fixed rate of interest.
