Fourth quarter (Q4)

“The fourth and final quarter of a financial year; for a calendar-year business, it runs from October through December.”

Why fourth quarter (Q4) matters to a first-time founder

Q4 closes the financial year and often determines whether annual targets, budgets and reporting obligations are met. Founders may face pressure to accelerate sales or spending, but decisions should remain commercially sound rather than merely improving a year-end number.

Examples of fourth quarter (Q4)

A calendar-year retailer enters Q4 with £750,000 of annual sales and a £1 million target. Holiday demand could close the £250,000 gap, but management also models returns, fulfilment costs and cash collection instead of judging success from gross orders alone.

Common misunderstanding

Q4 is not universally October through December; it is the final three months of the organisation’s financial year. Strong Q4 sales may also reflect seasonality rather than lasting growth. Year-end revenue must follow the applicable revenue recognition rules, not management preference.

When to use it

Use Q4 for final forecasts, year-end close planning and setting the next annual budget. Confirm reporting dates with advisers and stakeholders. Do not offer uneconomic discounts, delay legitimate costs or recognise revenue early simply to hit a target; those choices can mislead.
