#### Duration, T = 364 days (12 Months without 1 Days)

#### Commission fee (withdrawal or payment), F = - 364%

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

## I = Simple interest:

#### I = (P × R × T) ÷ N =

#### (4,018 × 2,018% × 364) ÷ 365 =

#### (4,018 × 2,018 × 364) ÷ (365 × 100) =

## B = Amount earned before deducting the

commission fee (withdrawal or payment):

#### B = P + I =

#### 4,018 + 80,861.094136986301 =

#### 84,879.09

## D = Amount earned after deducting the

commission fee (withdrawal or payment):

#### D = B - F =

#### B - F% × B =

#### (1 - F%) × B =

#### (1 - (- 364%)) × 84,879.094136986301 =

#### (1 + 364%) × 84,879.094136986301 =
