What Is Simple Interest?

Simple Interest is a fast and simple strategy for ascertaining the interest charge on an advance. Simple Interest is controlled by increasing the everyday loan fee by the principal by the number of days that pass between installments.

A calculator that calculates a Simple Interest Rate is called a Simple Interest Calculator.

Simple Interest Calculator Uses

This simple interest calculator ascertains a collected sum that incorporates the principal in addition to interest. For interest just, utilize the simple interest calculator.

Simple Interest Equation:

A = P(1 + rt)


A = Total Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

r = Rate of Interest every year in decimal; r = R/100

R = Rate of Interest every year as a percent; R = r * 100

t = Time Period associated with months or years

From the base equation, A = P(1 + rt) got from A = P + I and I = Prt so A = P + I = P + Prt = P(1 + rt)

Simple Interest Formulas and Calculations:

Utilize this simple interest calculator to discover A, the Final Investment Value, utilizing the simple interest equation: A = P(1 + rt) where P is the Principal measure of money to be contributed at an Interest Rate R% per period for t Number of Time Periods. Where r is in decimal structure; r=R/100; r and t are in similar units of time.

The collected measure of a venture is the first principal P in addition to the accumulated simple interest, I = Prt, in this way we have:

A = P + I = P + (Prt), and finally A = P(1 + rt)

  • Calculate Total Amount Accrued (Principal + Interest), solve for A
  • Calculate Principal Amount, solve for P
  • Calculate rate of interest in decimal, solve for r
  • Calculate rate of interest in percent
  • Calculate time, solve for t
    • t = (1/r)(A/P - 1)

○A = P(1 + rt)

○P = A / (1 + rt)

○r = (1/t)(A/P - 1)

○R = r * 100
