#### Principal (initial amount), P = 8,995

#### Annual simple interest rate, R = 1%

#### From date: May 27, 2017

#### Duration, T = 214 days (7 Months)

#### Commission fee (withdrawal or payment), F = 0.2%

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

## I = Simple interest:

#### I = (P × R × T) ÷ N =

#### (8,995 × 1% × 214) ÷ 365 =

#### (8,995 × 1 × 214) ÷ (365 × 100) =

#### 1,924,930 ÷ 36,500 =

#### 52.737808219178 ≈

#### 52.74

## B = Amount earned before deducting the

commission fee (withdrawal or payment):

#### B = P + I =

#### 8,995 + 52.737808219178 =

#### 9,047.737808219178 ≈

#### 9,047.74

## D = Amount earned after deducting the

commission fee (withdrawal or payment):

#### D = B - F =

#### B - F% × B =

#### (1 - F%) × B =

#### (1 - 0.2%) × 9,047.737808219178 =

#### 99.8% × 9,047.737808219178 ≈

#### 9,029.64233260274 ≈

#### 9,029.64

## Pr = Investment profit:

#### Pr = D - P =

#### 9,029.64233260274 - 8,995 =
