Formula To Calculate Maturity of Simple Interest

When considering the future value of your loan or investment subject to simple interest, it's important to know the formula that governs the calculation. The maturity amount of your investment with simple interest is determined using a simple formula, A= P (1 + r*t)

A = Total amount,
r = Rate of Interest,
t = Tenure in years,
P = Principal Amount.


Consider an amount of ₹5,00,000 for 5 years at an annual interest rate of 7%, then the maturity value would be:

A= P (1 + r*t)

A= 500,000(1+7.5/100)

A= 675,000

So, the maturity amount (A) for an investment of ₹500,000 for 5 years at an annual interest rate of 7% is ₹675,000.

How to Calculate Total Interest Earned?

Having clarity about the total interest on your investment empowers you to make confident financial decisions. Here’s how! You can easily determine the total interest, whether to be earned or paid, by employing the formula SI = P x R x T/100, where,

SI = Simple Interest
P = Principal amount
R = Rate of Interest
T = Tenure in years


Again, let’s consider an amount of ₹5,00,000 for 5 years at an annual interest rate of 7%, then the total interest would be:

SI = 500000 x 7 x 5/100

SI = 500000 x 7 x 0.05

SI = 500000 x 0.35

SI = 1,75,000

With an annual interest rate of 7%, the total interest on an investment of ₹5,00,000 for 5 years would be ₹175,000.
