Most go-to-market plans fail on arithmetic before they ever fail in the market. Here’s a 30-minute exercise that tells you whether yours adds up.
Ask a founder about their go-to-market strategy and you’ll usually hear a story: the ideal customer, the positioning, the three channels they’re “leaning into” this year. Ask how many leads those channels need to produce each month to hit the revenue target, and the conversation tends to get quieter.
That gap between narrative and numbers is where a lot of marketing budgets go to die. And it’s about to get more expensive.
On October 21, Forrester published its 2027 B2B go-to-market predictions, forecasting that AI agents will influence 75 percent of B2B purchase decisions. The research firm also expects two-thirds of providers to lose deals because buyers can’t verify their claims, and warns that marketing leaders may cut as many as a quarter of roles in anticipation of AI productivity gains that fall short.
“In 2027, the defining challenge for B2B go-to-market leaders will be to make deliberate choices about what to automate and where human judgment still matters,” Sharyn Leaver, Forrester’s chief research officer, said in the announcement.
Deliberate choices require something most GTM plans don’t have: a model. Not a deck, not a list of channels, but a set of numbers that connect what you spend to what you expect to earn. Here’s how to build one before you commit the budget.
Start With the Gap, Not The Channels
The most common mistake is planning forwards from tactics. A founder decides to “do LinkedIn, some PR, and a webinar series,” allocates a budget that feels reasonable, and hopes the revenue follows.
Flip it. Start with the number you need to close.
Take a hypothetical B2B software company doing $2 million in annual revenue with a goal of reaching $3 million in 12 months. The gap is $1 million in new bookings. Everything in the plan should exist to close that gap, and you should be able to say how.
Work Backward Through The Funnel
Now translate the gap into customers, then into leads.
Say the average first-year contract is worth $20,000. Closing a $1 million gap means signing 50 new customers. If 2 percent of leads eventually become customers, you need 2,500 leads over the year.
That’s roughly 208 leads a month. Write that down. It’s the first number most plans never state out loud.
Account For The Sales Cycle
Here’s where many plans quietly break. If your average sales cycle runs four months, a lead generated in month nine probably won’t close until after your 12-month window ends.
In practice, only leads from the first eight months count toward this year’s target. So the real requirement isn’t 208 leads a month. It’s closer to 313, front-loaded into the first two-thirds of the year.
A plan that ramps marketing slowly and “scales in the back half” can be mathematically incapable of hitting its own goal. You won’t see that in a slide. You’ll see it in a spreadsheet.
Put a Price On Every Lead
Next, estimate what a lead costs you. If your blended cost per lead across channels is $150, generating 2,500 leads costs $375,000.
Then check the return. At a 70 percent gross margin, $1 million in new revenue produces $700,000 in gross profit. Spending $375,000 to earn it gives you a return on marketing investment of about 87 percent.
That looks healthy. Now stress-test it. If your cost per lead is actually $250, the budget rises to $625,000 and the return falls to roughly 12 percent. If conversion slips from 2 percent to 1.5 percent, you need about 3,333 leads instead of 2,500.
Small changes in assumptions move the outcome dramatically. That’s the point of running the math: you find out which assumptions your plan depends on before the market tells you.
Treat Channels Like a Portfolio
Only after the funnel math works should you decide where the money goes. The strongest GTM teams treat channels the way an investor treats assets, each with a role, a cost profile, an expected return, and effects on the others.
A useful frame is PESO: paid, earned, shared, and owned media. Paid ads can generate leads quickly but stop the moment spending stops. Owned channels, such as your website and content, compound slowly. Shared channels build community and reach. Earned media, meaning press coverage and third-party mentions, builds the credibility buyers look for when they validate a decision.
That last category deserves a fresh look in light of Forrester’s forecast. If buyers increasingly rely on AI tools to research and fact-check vendors, the predictions suggest GTM teams will need credible, consistent proof points that those tools can index and validate. Independent coverage is one of the few signals a vendor can’t simply assert about itself, strengthening an effective go-to-market strategy.
The practical takeaway: don’t evaluate channels one at a time. Ask what each one does for the others, and whether the mix as a whole can produce the lead volume your funnel requires.
Use a Calculator, Not a Gut Check
None of this requires a finance team. A spreadsheet works. So do purpose-built tools.
One example is PlotGTM, a free go-to-market strategy calculator that asks for current revenue, a target, a time horizon, conversion rates, average deal size, margin, and sales-cycle length. It then models a budget, a channel mix across paid, earned, shared, and owned media, a funnel forecast, and return on marketing spend. It can also work backward from a revenue gap to estimate the budget and monthly lead volume required.
“If your strategy can’t survive one honest calculator, the problem is your assumptions, not the market,” says Alexander Storozhuk, the founder behind PlotGTM.
Whatever tool you use, the value isn’t the output. It’s being forced to write down every assumption and see how they interact.
The 30-Minute Test
Before you approve next year’s marketing budget, answer these questions in writing:
What’s the Revenue Gap?
The difference between where you are and where you need to be, in dollars.
How Many Customers Close It?
Divide the gap by your average deal size.
How Many Leads Does That Require?
Divide customers by your lead-to-customer conversion rate.
When Do Those Leads Need to Arrive?
Adjust for the length of your sales cycle.
What Does Each Lead Cost?
Use real numbers from past campaigns, not hopes.
Does The Return Justify The Spend?
Compare gross profit from new revenue to total marketing cost.
What Breaks The Plan?
Change your two shakiest assumptions by 25 percent and see what happens.
If you can’t answer one of these, that’s the most important thing you’ve learned all quarter. The market will eventually test your go-to-market strategy. It’s far cheaper to test it yourself first.
