How to Allocate Budget for Digital Marketing (UPDATED)

Google ‘Marketing Budgets’ and you’ll find a tonne of reports that are all contradictory to one another, telling you how to allocate budget for digital marketing.

Some will shout Brexit at you, telling you to watch your step but still to invest.

Others will talk about oversaturation in almost every market and how now is the time to differentiate yourselves: “Spend, spend spend!”

 The fact is, you can do as much reading as you want, there’s just no simple answer to the big question:

“What should my marketing budget be?”

I mean, how relevant are general trend reports to any specific business, anyway?

You might see that “brands increased their budgets at the slowest rate (2.5%) for almost three years in the third quarter of 2018*” – but what if brands in your sector bucked that trend?

You can read every single report out there, and you still might be none the wiser.

You don’t want to pluck a figure out of thin air.

What you’re looking for is a simple, mathematically-sound method to help you identify how much you should be spending on marketing.

There is a general rule of thumb taught at many universities and quoted by business mentors and entrepreneurs across the world is that your marketing spend should be 5% of turnover to maintain your market position and 10% of turnover to grow.

But my issue with this is that there are so many variables involved, how can any business follow a ‘general rule of thumb’?

So, what are your options?

You could spend nothing…

You could spend what you’ve always spent…

You could stick your finger in the air…

You want next year to be better than last, so you increase your marketing budget.

Or maybe – just maybe – you could plan strategically:


Forget guesswork, habit and general trends – to work out how to allocate budget for digital marketing,
 you need to outline your financial objectives and exactly what you want to achieve.

As with anything in life, nothing is simple. The number of variables involved in planning a budget are huge. That said, with the right, strategic process, you’ll get a good, ballpark figure to go from.

If it’s out of your league, chances are you’re either trying to grow too quickly, your cost per acquisition is too high or your close rate is too low.

Anyway, without further ado, this is how we’d recommend going about your marketing budget planning.

A Simple Process to Allocate Budget for Digital Marketing

Step 1: Evaluate

Look at your marketing and sales metrics for the last 12 months. They will have a lot of the information you’ll need to evaluate in marketing budget planning for the next year.

Some of the key things you’ll want to look at are:

That said, don’t solely rely on cold, hard data. Clever budget planning requires a balance between left brain analytics and right brain knowledge.

Speak to your staff about what they think went right and wrong, where they think spend was wasted and could’ve been better invested.

Often, your team as a whole already knows the answers, you just have to ask the questions.

Step 2: Do Some Maths

Next you’ll need to divide your total revenue by the number of customers to get the average spend per customer.

It’s also worth looking at your revenue growth against the number of new deals that were done last year – both for new customers and existing ones.

Another calculation you might want to look at would be how much of your revenue can be attributed to new customers vs existing customers simply increasing their spend.

This will give you a good picture of the overall financial landscape in your business.

Step 3: Set Your Goals

This is the most important part of any budget. If you don’t know where you’re going, how on earth will you know when you get there?

Start by identifying how much you want to increase your revenue by in 2019.

And don’t just say 100000%.

Goals need to be realistic and measurable, taking into account the opportunity in the market, as well as how much you can actually spend to achieve it.

You’d be amazed how many potential clients come to us and say they want to grow the business by £20m but only want to spend £5k to get there.

We might be good, but nobody’s that good!

Once you’ve worked out how much you want to increase revenue by as a number (not a percentage), divide  this by the average spend per customer, as worked out in step 2.

This will give you the number of new customers you need to win to achieve the growth in revenue.

Step 4: Finalise

Take your total marketing spend in 2018 and divide it by the number of new customers you acquired last year.

This will give you the cost per acquisition of a new customer.

Now, if you multiply that by the number of new customers you need to achieve your revenue growth identified in step 3, you should get a ballpark marketing budget for 2019, set against your goals. 

In Summary

You’ll notice in the steps above I’ve used the term ‘new customer’ a fair few times.

Let’s not forget that there will, of course, be revenue coming in from repeat and retained business too. So, with both new and existing customers in mind, here a few other considerations you’ll need to make:

As we said at the start, there’s no easy or clear cut way to define your budget. Even if you do define one, we can almost guarantee you’ll spend less or more than the final figure you come up with.

It could be that, due to poor spend, you actually spend less than last year but get more new business off the back of it.

It’s incredibly important to get a budget down on paper which is set against specific goals in order to make sure you can actually afford to achieve the growth you dream of.
