Most small business marketing plans are built the same way. You decide you want to grow, pick a few channels that seem to work for others (Google Ads, Facebook, a home show, maybe a new website), and set a budget that feels about right. Then you wait to see what happens.
The trouble is that “about right” can cost a lot. If each new customer costs more to win than they’re worth, more marketing only makes the problem bigger. And if the money goes out months before the revenue comes in, a good plan can still leave you short on cash.
PlotGTM is an online calculator that helps you check those numbers before you spend. You don’t need an account. You enter a few facts about your business, and it lays out the components of GTM strategy your growth goal depends on: how many leads, how much budget, which mix of channels, how much cash up front, and whether the plan pays for itself.
Here’s how to use it, step by step.
Before you start: gather five numbers
You’ll get the most out of PlotGTM if you have these ready. Rough figures are fine for a first pass.
- Current annual revenue. The tool accepts revenue from $100,000 upward.
- New leads per month. Calls, form fills, quote requests: whatever counts as a real inquiry for you.
- Lead-to-customer conversion rate. Out of every 10 leads, how many become paying customers?
- Average order value. What a typical job or sale is worth.
- Gross margin. What’s left of each sale after the direct cost of delivering it, as a percentage.
It also helps to know how many times a typical customer buys from you during the campaign period, and roughly how many days pass between a customer’s first contact and their first purchase.
Step 1: Describe your situation
Open PlotGTM and start with the Your situation panel on the left.
- Demand. Choose “Established demand” if people already search for what you sell (a plumber, a roofer, an accountant). Choose “New market” if you have to explain the category before people want it.
- Days to purchase. Move the slider to match how long customers usually take to decide. An emergency repair might be a few days; a kitchen remodel might be months. A longer cycle means more touchpoints, so the tool leans more on channels that build trust over time, like content, email, PR and webinars, and less on pay-per-click ads.
- Market. Pick Local, National or International.
- Current revenue and revenue goal. The goal is what you want to earn over the campaign period, and it can’t be lower than your current revenue.
- Campaign horizon. Choose 6, 12, 18 or 24 months.
Step 2: Choose how to set your budget
PlotGTM gives you three ways to size a marketing budget, plus an Auto option that picks the best fit for your inputs.
- Goal-driven works backward from your revenue goal. It tells you how many new leads a month and how much budget you’d need to close the gap between where you are and where you want to be, and whether that budget is affordable.
- Unit economics caps spending at one-third of the gross profit the campaign is expected to produce. It’s the conservative option: marketing never eats more than a third of the margin it earns.
- % of revenue sets aside a share of your annual revenue, anywhere from 1% to 20%, spread over the campaign.
If you’re unsure, leave it on Auto and see which method it chooses. You can tap any option to compare.
Step 3: Set your growth levers
Next, enter the numbers you gathered: new leads per month, conversion rate, average order value, purchases per customer and gross margin.
One thing worth knowing: PlotGTM uses these numbers exactly as you enter them. It doesn’t quietly boost your lead count because you picked a strong channel mix. Instead, a Mix support badge tells you whether your mix of channels looks strong enough to back each target. If a badge shows weak support, either the target is optimistic or the mix needs adjusting.
Step 4: Review your channel mix
PlotGTM splits your budget across four groups of media, known as PESO:
- Paid: ads, sponsored content, trade shows.
- Earned: press coverage and PR.
- Shared: social media.
- Owned: your website, blog, newsletter, webinars and events.
You’ll see the split as a chart, with dollar amounts for each channel. If a channel doesn’t make sense for your business, uncheck it. The budget rebalances across the remaining channels automatically. PR is capped at 15% of the total, with any excess moved to paid channels.
Step 5: Check your unit economics
This is where many plans fall apart, so take your time here.
PlotGTM calculates a safe customer acquisition cost (CAC) ceiling: the most you can afford to spend to win one customer. It then estimates what pay-per-click ads would actually cost per customer. If the ad cost is higher than your ceiling, the tool flags it and suggests moving budget toward channels like branded content and PR.
You’ll also see:
- ROMI (return on marketing investment): gross profit from the campaign, minus what you spent, divided by what you spent.
- ROI: revenue minus spend, divided by spend.
- Payback: how many months it takes for the campaign’s gross profit to cover its cost.
Step 6: Plan for cash
The capital need chart is easy to overlook and very useful for a small business. It shows how your cash balance moves month by month when you pay for marketing up front and customers pay you over time. The lowest point on the curve is the cash you need in the bank before you start. If the curve never dips below zero, the campaign funds itself from month one.
Step 7: Look at people, tools and the budget split
Finally, PlotGTM shows how a total budget breaks down: 25% for the people who run the work, 2% for software, 10% held back for keeping existing customers (remarketing, email, CRM), and 63% for the media mix itself.
It also suggests a marketing team and marks each role as in-house or agency/fractional, depending on what the people budget can cover. For most small businesses, that means outside help for most roles. That’s normal, and the tool says so plainly. You’ll also get a starter list of tools for each channel.
What it looks like with real numbers
PlotGTM’s built-in demo is a $5 million company planning six months of marketing at 2,000 leads a month, a 4% conversion rate, an $1,800 average order and a 45% gross margin. It looks like a solid plan. The calculator shows that it covers only 49% of the $3.5 million revenue gap, that paid search would cost about $1,907 per customer against a safe ceiling of $972, and that the business would need about $65,800 in cash before the campaign turns positive.
Most small businesses are smaller than that, but the logic scales down. Here’s a quick illustration, worked by hand using the formulas PlotGTM publishes in its FAQ. It’s a hypothetical example, not output from the tool.
Hypothetical: a local HVAC company
60 leads a month, 20% conversion, $1,200 average job, 1.5 jobs per customer over six months, 40% gross margin.
- Customers over six months: 60 × 6 × 20% = 72
- Revenue: 72 × $1,200 × 1.5 = $129,600
- Gross profit at 40%: $51,840
- Unit-economics budget (one-third of gross profit): about $17,280, or roughly $2,880 a month
- Value per customer (job × purchases × margin): $1,200 × 1.5 × 40% = $720. PlotGTM sets the safe CAC ceiling at about 60% of that, or roughly $432 per customer.
If your Google Ads are currently costing $600 to win a customer, you now know that channel is losing money on every job, before you raise the budget.
Plug your own numbers into PlotGTM and it will do this math for you, along with the channel mix, cash curve and team plan.
Common mistakes to avoid
- Starting with channels instead of the goal. Decide what revenue you need first, then let the numbers tell you what it takes.
- Using your best month as the baseline. Use typical conversion rates and order values, not your record.
- Ignoring the sales cycle. If customers take three months to decide, leads you generate late in the campaign won’t turn into revenue until after it ends.
- Forgetting cash. A plan that’s profitable on paper can still leave you short in month two.
A planning tool, not a crystal ball
PlotGTM is clear about its limits. Its methodology note describes its assumptions about sales cycles, acquisition costs and channel impact as “directional, not guarantees,” and says the tool is meant to help users “align stakeholders and pressure-test budget proposals.” Its benchmarks draw on published research from sources including Gartner, Forrester, Les Binet and Peter Field, and RAIN Group.
Treat the results as a starting point for a better conversation with your partner, your accountant or your marketing agency. If the numbers don’t work in the calculator, they’re unlikely to work in real life.
