What is Gross Profit?
Gross profit is your revenue minus the direct costs of producing your goods or services (cost of sales). It's calculated before operating expenses.
How Gross Profit Works in Practice
Step by Step
To calculate gross profit, take your total revenue for the period and subtract all direct costs of sales. The formula is: Gross Profit = Revenue - Cost of Sales. This figure appears near the top of your P&L statement, after revenue and cost of sales but before operating expenses.
For accurate gross profit calculation, you need to correctly classify costs as either direct (cost of sales) or indirect (overheads). Direct costs are those that would not exist if you did not make the sale -- the product you bought to resell, the subcontractor you hired for the project, the raw materials you used. Indirect costs exist regardless of any individual sale -- your office lease, your accountant's fee, your company insurance.
Gross profit margin is calculated as (Gross Profit / Revenue) x 100. Track this monthly to spot trends. If your margin is dropping, investigate whether it is due to price pressure, supplier cost increases, or a change in your product/service mix towards lower-margin offerings.
Practical Tips
Common Mistakes to Avoid
- Including overhead expenses like rent and insurance in cost of sales, which understates your gross profit
- Not including all direct costs (like subcontractor fees or delivery costs) in cost of sales, which overstates gross profit
- Ignoring gross profit margin trends and only looking at the absolute gross profit figure
- Confusing gross profit with net profit -- gross profit does not account for overheads, interest, or tax
