#### Principal (initial amount), P = 10,000

#### Annual simple interest rate, R = 0.15%

#### From date: Feb 21, 2018

#### To date: Mar 21, 2018

#### Duration, T = 28 days

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

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

## I = Simple interest:

#### I = (P × R × T) ÷ N =

#### (10,000 × 0.15% × 28) ÷ 365 =

#### (10,000 × 0.15 × 28) ÷ (365 × 100) =

#### 42,000 ÷ 36,500 ≈

#### 1.150684931507 ≈

#### 1.15

## B = Amount earned:

#### B = P + I =

#### 10,000 + 1.150684931507 =

#### 10,001.150684931507 ≈

#### 10,001.15
