Why growing revenue is not the same as growing profit

A line graph showing 2 lines growing at different paces to represent how revenue and growth don't always grow at the same rate/time.

Many business owners assume that growing revenue automatically means profit will grow at the same rate. More customers, more sales, more money. The logic makes sense but it’s not always the case.

It can often feel frustrating. You're working harder, revenue is climbing, and things seem like they're going really well, but your bottom line doesn't reflect that.

This is because revenue and profit are two very different metrics. A business can generate significantly more revenue and still see profit stagnate, shrink or even disappear entirely. Beneath the surface of revenue growth are often inefficiencies or other problems that quietly erode profit margins. When this happens, the business ends up in a weaker financial position even though it seems more successful from a revenue perspective.

What causes the gap between revenue growth and profit growth

When revenue increases but profit doesn’t keep pace, it usually comes down to one or more of the following:

Rising costs

  • Software and subscription costs that accumulate from needing additional software or user licenses
  • An increase in the cost of delivering your product/service
  • Rising customer acquisition costs from expanded advertising, market saturation or less efficient channels

Pricing

  • Pricing not keeping pace with rising costs
  • Heavy discounting that generates sales volume but lowers profit margin per sale

Operations

  • Internal processes that haven’t scaled efficiently
  • Scope creep for project-based work
  • Jobs taking longer than quoted or priced
  • Capacity constraints when demand exceeds what existing systems can handle
  • Extra admin and support burdens that can come from having more customers

Labour

  • Premature hiring
  • Payroll growing at a faster rate than revenue

Customer and revenue quality

  • Taking on clients or projects that cost more to serve (i.e. more revisions, customisation, or support than your average customer)
  • Growth weighted towards lower-margin products or services rather than higher-margin ones
  • Increased product returns and refunds that add processing and admin costs

When a business is growing fast, it's easy for a few of these to compound at the same time. Sales are coming in and the product or service needs to be delivered, but the processes and costs behind it are under pressure to keep up. The combination of these pressures is often what creates the gap between revenue growth and profit growth.

A real-world comparison

Consider two businesses side by side.

Business A focused on growing revenue. 

They ramped up their advertising spend and offered frequent promotional discounts. Their sales volume climbed, resulting in revenue growing from £1,000,000 to £2,000,000. However, the extra volume pushed up fulfilment costs and return rates. The profit made was £140,000.

Business B focused on profit. 

They reviewed their product mix, discontinued two low-margin lines, and streamlined the delivery process to cut out a step that was adding extra admin time to every job. Their revenue remained steady at £1,000,000 but the improvements to product mix and operations led to better overall margins. The profit made was £220,000.

Business A looks twice the size on paper, but Business B is the more profitable one. Business A retains 7 pence from every pound of sales, where Business B retains 22 pence from every pound of sales.

Growing sustainably

Business growth should always aim to improve your financial strength rather than just making you (and your team) busier. 

At a minimum, revenue and profit should grow at the same rate, so if revenue grows 5%, net profit also grows 5%. In a well-optimised business, profit should actually grow faster than revenue, so if revenue grows 5%, net profit might grow 7-8%. This is because the business is set up for sustainable growth which allows revenue to increase without negatively impacting margins.

To optimise your business for sustainable growth:

  • Build scalable systems and operating procedures that work well today and will easily hold up at double your current size
  • Track profitability by product, service or client type so you can focus on growth that’s actually worth having
  • Set strict boundaries around discounting and scope creep to protect net returns on every job/sale
  • Audit recurring costs quarterly or every six months (especially software subscriptions which are notorious for cost creep)
