From Forecast to Budget: Four Steps to Fund Your Revenue Target

TL;DR

• A revenue forecast tells you what you want to achieve. A Go-To-Market budget tells you what it will cost to get there.  
• Start with your revenue target and the number of customers needed to reach it.  
• Model each Go-To-Market motion to understand what it produces, what it costs, and what limits its capacity.   
• Use those numbers to decide where to invest, then build a budget that connects your growth target to the resources required to deliver it. 

The revenue forecast is approved. The target is set. 

Now the sales leader wants another person. Marketing wants more budget for trade shows. Someone suggests increasing outbound activity. 

All reasonable requests. 

But which investment will actually help you hit the number? 

You cannot answer that by looking at the forecast alone. You need to know what each Go-To-Market motion produces, what constrains it, and what it will cost to get more out of it. 

Here is how to work through those decisions in four steps. 

Step 1: Start With Your Revenue Forecast 

You need two numbers from your forecast: 

• How much new revenue do you want to generate?  
• How many new customers will it take to generate it?  

Let's work through an example. 

A B2B company has a target of $1 million in annual revenue from new customers. Based on its forecast, it needs to acquire 36 customers to reach that number. 

That works out to approximately $27,778 in annual revenue per new customer, on average. 

Those are the numbers we will use throughout this article. 

Without them, you are not building a Go-To-Market budget. You are taking last year's spend, adding a percentage, and hoping the revenue follows. 

I call that hopecasting. 

A credible budget starts with the result you are trying to produce. 

Step 2: Calculate What Each Go-To-Market Motion Produces and Costs 

You reach your target through your Go-To-Market motions: the repeatable ways your company brings in business. 

For a traditional B2B company, those might include trade shows, inbound advertising, referrals, outbound sales, or a dealer network. 

Model each motion separately. 

You want to know three things: 

1. What goes into it?  
2. What comes out of it?  
3. What does it cost?  

Start With the Inputs 

Take trade shows as an example. 

The cost is not just the invoice for booth space. 

You also need to account for booth design, freight, travel, accommodation, entertainment, and the time your people spend preparing for and attending the show. 

The objective is to understand the true cost of running the motion, not just its most visible expenses. 

Then Model the Output 

Now look at what the trade show is expected to produce. 

For example: 

You cannot win a quarter of a customer. These are expected outcomes in a forecast, not a count of actual deals. 

The point is that you can work backward from customers to opportunities, leads, and the activity required to produce them. 

You can also work forward. 

If you increase booth traffic but your team cannot follow up with the additional leads, more traffic may not produce more customers. 

That is why it's important to model the full motion. 

Track Where Customers Come From 

None of this works without attribution. 

If your company attends a show and comes away with a vague sense that it went well, you cannot make a credible decision about next year's trade show budget. 

You need to know which leads became opportunities, which opportunities became customers, and what revenue those customers generated. 

Attribution will not always be perfect. A buyer might meet you at a show, visit your website, and speak with a salesperson before purchasing. 

Use a consistent method, document your assumptions, and avoid counting the same customer twice. 

You need numbers you can make decisions with. 

Step 3: Decide Where to Invest 

Once you have modelled each motion, you can compare them. 

Here is how our example company's $1 million target breaks down: 

Trade shows cost approximately 13 cents for every dollar of revenue they produce. Outbound costs approximately 59 cents. 

That is a substantial difference. 

Your first instinct might be to move money from outbound into trade shows. 

But there is another question to answer first. 

Can trade shows produce more revenue? 

Find the Constraint Before You Add the Budget 

A motion can be efficient and still have limited room to grow. 

• Perhaps you already attend every relevant trade show your buyers attend. 
• Perhaps your booth generates plenty of interest, but your sales team cannot follow up quickly enough. 
• Or perhaps you can generate more leads, but the conversion rate is too low to justify the additional spend. 

These are different problems, requiring different investments. 

I look for three types of constraints. 

1. Not enough volume. You need more of the input that starts the motion: booth visits, inbound inquiries, outbound contacts, or dealer prospects. 
2. Not enough capacity. The demand is there, but your team cannot handle it. Leads sit untouched. Dealer onboarding takes too long. Opportunities stall because nobody has time to move them forward. 
3. No room left to scale. You have reached the practical limit of the motion. More spending will not necessarily produce more customers. 

Until you know which constraint you are dealing with, adding money is a guess. 

Price the Cost of Removing the Constraint 

Let’s say your dealer network is generating more inquiries than your team can qualify and onboard. 

Your first instinct might be to hire. 

Before you do, calculate the at-risk capital on that hire: the money and resources you will commit before the person starts producing. 

That includes compensation during the expected ramp period, training, the time other employees spend supporting the new hire, and the software and equipment they need. 

Let’s say that investment comes to $60,000. 

Now you have something to compare against. 

What else could $60,000 do for the same Go-To-Market motion? 

Could a CRM workflow remove administrative work? Could a dealer portal shorten onboarding? Could a better qualification process help the existing team convert more inquiries? 

The answer might still be to hire. 

But now you are comparing the at-risk capital against other ways to remove the constraint, not simply approving another salary because the team is busy. 

Decide When to Add the Resource 

Timing is important because you usually spend the money before the revenue arrives. 

You can wait until the constraint is obvious, or you can invest ahead of demand when your forecast gives you enough confidence to do so. 

Both approaches have costs. 

• Hire too early, and you carry unused capacity. 
• Hire too late, and you may miss opportunities, delay dealer onboarding, or leave interested buyers waiting. 

Your forecast should help you see when the demand is likely to arrive. Your budget should show when the investment needs to happen. 

That is how the two documents work together. 

Step 4: Build and Validate Your Go-To-Market Budget 

You now know what each motion is expected to produce and what resources it needs. 

The final step is to translate those motion costs into a company budget. 

One motion will usually draw from several budget categories. 

For example, the $64,000 trade show motion might include $25,000 in direct trade show expenses, plus its share of salaries, software, and marketing support. 

Where a resource supports more than one motion, allocate its cost using a reasonable, consistent method. 

It does not need to be perfect. It needs to be defensible. 

For our example company, the budget looks like this: 

It’s the same $283,000 from the Go-To-Market motion model, now broken down by what you’re spending it on. 

Now you can assess whether the economics work. 

Calculate Your Cost of Growth 

Our company expects $1 million in annual new-customer revenue. 

Assume it earns a 50% gross margin on that revenue. 

That produces $500,000 in annual gross profit. 

Its Go-To-Market investment is $283,000. 

Cost of growth = $283,000 ÷ $500,000 = 56.6% 

In other words, the company plans to spend approximately 57 cents on Go-To-Market activity for every dollar of gross profit generated by the new-customer revenue target. 

That gives leadership a clearer view of the investment than revenue alone. 

Calculate Customer Acquisition Cost 

The company plans to acquire 36 customers. 

Customer acquisition cost = $283,000 ÷ 36 = $7,861 

It expects to spend approximately $7,861 to acquire each new customer. 

Now you can compare acquisition cost against what a customer is worth. 

Check Customer Lifetime Value and Payback 

Let's keep the assumptions consistent. 

The forecast implies average annual revenue of approximately $27,778 per new customer. 

Assume that revenue stays consistent, the average customer relationship lasts three years, and the company maintains a 50% gross margin. 

On these assumptions, each dollar spent acquiring a customer produces approximately $5.30 in lifetime gross profit. 

A commonly used planning reference is 3:1, although the right ratio depends on the business, its margins, retention, and cash flow. 

You should also look at how long it takes to recover the acquisition cost. 

At a 50% margin, an average customer generates approximately $1,157 in gross profit per month. 

CAC payback = $7,861 ÷ $1,157 = approximately 6.8 months 

That is an indicative payback period once the customer is generating revenue at the modelled rate. Actual cash recovery will depend on when the customer starts buying and when they pay. 

These numbers do not guarantee that the forecast will happen. 

They tell you whether the economics behind the plan make sense. 

Your Forecast Is Only as Good as the Budget Behind It 

A $1 million revenue target is easy to put in a spreadsheet. 

The harder question is what it will take to produce it. 

In our example, the company needs 36 new customers and a $283,000 Go-To-Market investment to reach its annual new-customer revenue target. 

Now leadership has something to work with. 

They can see which motions produce the most revenue, where capacity limits growth, and what additional resources could improve performance. 

They can see what customer acquisition costs and whether the expected return supports the investment. 

And they can have a more useful conversation about trade-offs. 

If the budget is too high, which motion can be improved? 

If the team cannot handle more demand, what capacity needs to be added? 

If the target cannot be reached with the available resources, does the business need to change the plan or change the target? 

Those are better questions than asking the sales team to do more with the same budget and hoping it works out. 

A revenue forecast tells you where you want to go. Your Go-To-Market budget tells you what it will take to get there. 

Build both.
