#### Principal (initial amount), P = 100

#### Annual simple interest rate, R = 756%

#### From date: May 24, 2017

#### To date: Jun 24, 2017

#### Duration, T = 31 days

#### Commission fee (withdrawal or payment), F = 2.5%

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

## I = Simple interest:

#### I = (P × R × T) ÷ N =

#### (100 × 756% × 31) ÷ 365 =

#### (100 × 756 × 31) ÷ (365 × 100) =

#### 2,343,600 ÷ 36,500 ≈

#### 64.208219178082 ≈

#### 64.21

## B = Amount earned before deducting the

commission fee (withdrawal or payment):

#### B = P + I =

#### 100 + 64.208219178082 =

#### 164.208219178082 ≈

#### 164.21

## D = Amount earned after deducting the

commission fee (withdrawal or payment):

#### D = B - F =

#### B - F% × B =

#### (1 - F%) × B =

#### (1 - 2.5%) × 164.208219178082 =

#### 97.5% × 164.208219178082 ≈

#### 160.10301369863 ≈

#### 160.1

## Pr = Investment profit:

#### Pr = D - P =

#### 160.10301369863 - 100 =

#### 60.10301369863 ≈

#### 60.1
