Calculating Gross Profit Margins

The gross profit margin calculation is a number used in all business accounts and entered into the profit and loss account.

It is sometimes called the gross margin and entered as an absolute number or a percentage, so the % value is the gross profit percentage.

How To Calculate Gross Profit

Calculating gross profit is a simple calculation in its rawest form and is:

Gross Profit Calculation Example

You have sales of £1,000, with direct cost of sale at £250. Your gross profit is £1,000 less £250 which equals £750.

All sales values get recorded net of VAT and discounts provided.

The profit and loss account records sales made during the period of the statement whether or not you have received payment for the sales made. VAT cash accounting is slightly different in that your VAT returns base numbers on cash received into your bank account.

In accounting terms, the raw products may include changes in stocks received at your premises. Different businesses use various formulae depending on their industry and requirements.

Calculating the Gross Profit Percentage

Rather like the calculation above calculating the percentage is the ratio of the gross profit number divided by the sales figure expressed as a percentage.

Example: taking the values outlined above, your gross profit percentage would be £750 profit divided by £1,000 sales giving 0.75 expressed as a percentage is 75%.
