How to measure and grow your sole trader business profit

As a sole trader running a business on your own, you may have some questions around profit. Like, for example, what is it? How important is it? And how do you grow it?

Companies often have teams of people working on analysing processes and growing revenue. But many sole traders can’t afford the same level of support. More than this, sole traders are unique in that they are their business – and most of the information out there doesn’t take this into account.

To help our community of sole traders kick start their business growth, we’re creating a series of articles focused on how to get to that next level. Starting with perhaps the most exciting piece of the puzzle – as a sole trader, how do you measure and grow business profit?

We’re so glad you asked. Let’s go!

What is profit?

Profit is essentially money left over in your business once you subtract all the costs associated with business activities. In other words, your revenue (money made by your business) minus expenses (all the costs associated with running your business).

Revenue minus expenses equals profit

For example, say you’re a nine-year-old girl running an old-fashioned lemonade stall. Your mum has a lemon tree growing in her greenhouse, so you get your lemons for free. The water you use to make your lemonade is also free (thanks mum!). But you have to pay for the cups and the sugar, which averages out to 5p per drink sold.

If you sell your lemonade for 50p a cup, and you sold 1,000 cups across two days (there was a local summer fair on!), your profit would be your revenue (£500), minus the cost to make your product (5p a cup).

Profit calculation: £500 revenue minus 1,000 cups at £0.05 each equals £450 profit

The three types of profit

While the above example works as a quick explainer for what profit is, it doesn’t take into account the full picture.

That’s because there are technically three different types of business profit, and each is calculated slightly differently.

  1. Gross profit
  2. Operating profit
  3. Net profit

Let’s use our lemonade stall example to look at each one.

1. Gross profit

Gross profit is calculated by taking your total revenue (money made through your business activity) and subtracting the costs directly associated with creating your products/services. These are known as your cost of goods sold (COGS).

It basically shows that you aren’t spending more to create goods/services than you make in selling them.

With the lemonade example, we took into account the materials involved in making and selling lemonade (lemons, water, sugar, cups). But we didn’t think about the labour costs involved, which must be included in a gross profit calculation.

Let’s say the hourly wage of a self-employed nine-year-old is £8. Not bad!

If you spend four hours brewing and packing your lemonade, and then another 10 hours selling it at your stall, the total cost of your labour is £112.

So the equation to calculate your gross profit becomes: £500 - (1,000 x £0.05) - £112 = £338.

Gross profit calculation: £500 revenue minus 1,000 cups at £0.05 each minus £112 labour equals £338 gross profit

2. Operating profit

Operating profit is like gross profit, but it includes all other costs incurred while running your business – think things like rent, electricity, gas, and internet. It’s calculated pre-tax, and excludes any interest you may owe.

You use operating profit to show that your business can run at a profit, excluding the things you don’t have control over (tax and interest rates). To calculate your operating profit, you take your gross profit, and subtract your operating costs (also called overhead or fixed costs).

Going back to your lemonade stall, operating costs might include the cost of the equipment used to make the lemonade, the stall itself, and the fuel for transport. To keep things simple, let’s say all this amounts to £50.

£338 - £50 = £288 operating profit.

Operating profit calculation: £338 gross profit minus £50 overhead costs equals £288 operating profit

3. Net profit

Finally, net profit is operating profit, minus tax and interest. In real terms, net profit is a business’ take home pay.

In this example, a nine year old with a lemonade stall generally wouldn’t owe tax to HMRC. But let’s say your parents decided they wanted to teach you about business by funding your enterprise with a loan of £100 (covering all upfront costs), at an interest rate of 2%. That’s £2 in interest.

Your net profit is calculated after interest, meaning you’ll have to include it in your costs calculation:

£288 - £2 = £286 net profit.

Net profit calculation: £288 operating profit minus £100 business loan at 2% interest equals £286 net profit

What does “profit” mean for sole traders?

With all three of these definitions in mind, which one should sole traders use to measure their business growth?

Honestly, it depends – on your situation, what you want to know, and what you plan to do with that information. There are two key ways to think about it:

For starters, you’ll need to consider your take-home pay. Are you making enough to cover your living expenses? What’s the minimum you need to make each week/month, taking into account your business expenditure? You’ll generally need to factor living costs into your calculations.

Secondly, what are your goals? Do you need more funds to grow your business? Are you wanting to increase your earnings? Or even introduce a new product/service into the market? Measuring and growing profit can play into all of these.

Finally, when calculating profit, you’ll need to be careful to capture your true expenses. For example, things like charging for your time (super important for sole traders!), rent, power, fuel, internet, mobile phone bills, and of course, tax and financial admin. Including everything you can in your calculations will help you get the most accurate picture possible of your current profit margins.

As a general starting point, if you’re interested in figuring out the cost of creating your products/services, without factoring in overheads and fixed costs, take a look at your gross profit.

If you want to see if your business can run at a profit, you might want to consider your operating profit.

And finally, if you’re looking to increase your take-home pay, it could be beneficial to calculate your net profit.

Of course, you don’t have to stick to just one – you can use all three as a roadmap to get to where you want to go. Speaking of which –

How to increase your profit

Increasing your profit is simultaneously simple, and difficult. It’s simple because when it comes down to it, there are only three ways to do it:

  1. Make more money (eg. increase your revenue)
  2. Spend less (eg. decrease your expenses)
  3. A combination of both

While that’s pretty straightforward, the difficult bit is figuring out how you’re going to do it. That will depend on your business, and how it operates. So while we can’t give you a detailed list of actions to take, we can give you a few things to think about.

1. Claim all your allowable expenses (spend less)

We’re Hnry – of course we’re going to start with this one!

This doesn’t directly relate to profit calculations – it’s more about lowering your income tax bill. But if you’re not claiming all your allowable expenses, you could be missing out on tax savings you’re actually entitled to.

💡 For more on claiming expenses, check out the Hnry guide to tax deductions for sole traders.

2. Charge more (make more)

Are you undervaluing your own time? Are you sure? If you find that your margins are quite tight, it might be worth rethinking how you’re pricing yourself.

Luckily, we have a guide for that. It is technically for freelancers, but the fundamentals discussed apply for almost everyone.

3. Bulk purchase (spend less)

Can you negotiate with your suppliers to buy in bulk, and pay less per unit? If so, this is a great way to increase your profit margin.

4. Find cheaper suppliers (spend less)

You might be able to find a better price for your materials, without sacrificing quality. Why not shop around?

5. Bundle/unbundle your services (make more)

This goes back to your pricing structure again. Basically, if you bundle certain products or services together, could you charge more than they’re worth individually?

For example, if you’re a freelance writer, could you throw in a quick landing page optimisation service alongside your copywriting service, and increase your prices without putting in much more time?

Conversely, do you have services/products that are currently bundled together, that might be more valuable separately?

6. Lower your prices (make more)

This probably feels counterintuitive, but if your prices are prohibitive for your customers, lowering them might increase demand.

If this happens, you might make less per unit/job, but sell more in the long run.

Be very careful with this strategy – it could really work, but it could also backfire!

7. Offer new products/services (both)

It may not be what you set out to do when you started your business, but if there’s something you’re not doing that you think could be profitable, why not give it a try?

For example, if you make macrame plant holders, why not host a macrame class?

Or if you busk on the weekends, why not try gigging at your local pub? (Ask them about it, what do you have to lose?)

Or if you’re a freelance horse therapist, why not start selling fertiliser? Ok, we’re running out of ideas here, but you get the gist.

Basically, the sky’s the limit when it comes to your creativity and ingenuity. You already know you’re a self-starter – that’s why you started your business in the first place. Look at you go!
