» Margin Kasar

$$\text{Kos Barang Dijual} = \text{Jualan Bersih} - \left( \text{Margin kasar} \times \text{Jualan Bersih} \right)$$

$$\mathrm{COGS} = \mathrm{NS} - (\mathrm{GM} \times \mathrm{NS})$$

$$\text{Jualan Bersih} = \frac{\text{Kos Barang Dijual}}{1 - \text{Margin kasar}}$$

$$\mathrm{NS} = \frac{\mathrm{COGS}}{1 - \mathrm{GM}}$$

$$\text{Margin kasar} = \left( \frac{\text{Jualan Bersih} - \text{Kos Barang Dijual}}{\text{Jualan Bersih}} \right)$$

$$\mathrm{GM} = \frac{\mathrm{NS} - \mathrm{COGS}}{\mathrm{NS}}$$
