#### Principal (initial amount), P = 65,000

#### Annual simple interest rate, R = 0.75%

#### From date: Jul 20, 2015

#### To date: Jul 22, 2015

#### Duration, T = 2 days

#### Commission fee (withdrawal or payment), F = 144%

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

## I = Simple interest:

#### I = (P × R × T) ÷ N =

#### (65,000 × 0.75% × 2) ÷ 365 =

#### (65,000 × 0.75 × 2) ÷ (365 × 100) =

#### 97,500 ÷ 36,500 ≈

#### 2.671232876712 ≈

#### 2.67

## B = Amount earned before deducting the

commission fee (withdrawal or payment):

#### B = P + I =

#### 65,000 + 2.671232876712 =

#### 65,002.671232876712 ≈

#### 65,002.67

## D = Amount earned after deducting the

commission fee (withdrawal or payment):

#### D = B - F =

#### B - F% × B =

#### (1 - F%) × B =

#### (1 - 144%) × 65,002.671232876712 =

#### - 44% × 65,002.671232876712 ≈

#### - 28,601.175342465753 ≈

#### - 28,601.18

## Pr = Investment profit:

#### Pr = D - P =

#### - 28,601.175342465753 - 65,000 =
