How a profit and loss statement is built
Every profit and loss statement follows the same ladder, from the top line to the bottom line. Each rung answers a different question, which is why the template shows each subtotal on its own line:
- Income (revenue, sales): everything the business earned from its main activity in the period.
- Cost of goods sold: the direct cost of what was sold.
- Gross profit = income − cost of goods sold. Divided by income, it gives the gross margin: how much of each dollar of sales is left to run the business.
- Operating expenses: the cost of running the business whether or not you sell anything, such as rent, payroll, software, insurance and marketing.
- Operating income = gross profit − operating expenses. This is the profit from the business itself.
- Other income and expenses: items outside the main activity, such as interest earned on savings, interest paid on loans, or a gain on selling equipment.
- Net income = operating income + other income − other expenses. The bottom line.
Filling it in from your books or your bank statements
If your books are current, run a profit and loss report from your accounting software for the same period and copy the category totals. If they aren't, a statement-based approach works for a first draft:
- Convert each month's bank and credit card statements to Excel with the statement converter.
- Add a category column and assign each transaction to one of your line items. Leave transfers between your own accounts, loan principal and owner's draws out: they aren't income or expenses.
- Total each category with a pivot table or

Bank statements show cash in and out, so the result is a cash-basis statement. If you invoice customers or receive bills, the accrual-basis statement from your books will differ, sometimes a lot, around the start and end of the period.
Comparing two periods
Tick Compare with a prior period to add a second column, for example this year against last year, or this quarter against the same quarter last year. The Excel and PDF downloads add a change column. Comparing equal periods matters: a twelve-month year against a nine-month partial year will always look like growth.
Reading the result
- Gross margin tells you whether pricing covers direct costs. A falling gross margin with rising sales usually means costs or discounts grew faster than prices.
- Net margin is the share of income you keep. It's more useful compared over time for the same business than against other businesses.
- A loss shows in red and in parentheses, the accounting convention, in both downloads.
