#### Principal (initial amount), P = 1

#### Annual simple interest rate, R = 15%

#### From date: Jan 1, 1

#### To date: Jan 1, 9999

#### Duration, T = days

#### Commission fee (withdrawal or payment), F = 696%

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

## I = Simple interest:

#### I = (P × R × T) ÷ N =

#### (1 × 15% × ) ÷ 365 =

#### (1 × 15 × ) ÷ (365 × 100) =

#### 0 ÷ 36,500 =

#### 0

## B = Amount earned before deducting the

commission fee (withdrawal or payment):

#### B = P + I =

#### 1 + 0 =

#### 1

## D = Amount earned after deducting the

commission fee (withdrawal or payment):

#### D = B - F =

#### B - F% × B =

#### (1 - F%) × B =

#### (1 - 696%) × 1 =

#### - 596% × 1 =

#### - 5.96

## Pr = Investment profit:

#### Pr = D - P =

#### - 5.96 - 1 =
