#### Principal (initial amount), P = 400,000

#### Annual simple interest rate, R = 7.5%

#### From date: Mar 25, 2012

#### To date: Mar 25, 2022

#### Duration, T = 3,652 days (120 Months)

#### Commission fee (withdrawal or payment), F = 0%

#### No. of days in a year, N = 365

## I = Simple interest:

#### I = (P × R × T) ÷ N =

#### (400,000 × 7.5% × 3,652) ÷ 365 =

#### (400,000 × 7.5 × 3,652) ÷ (365 × 100) =

#### 10,956,000,000 ÷ 36,500 ≈

#### 300,164.383561643836 ≈

#### 300,164.38

## B = Amount earned:

#### B = P + I =

#### 400,000 + 300,164.383561643836 =

#### 700,164.383561643836 ≈
