From Gut to GPS: How to Make Financial Projections for Your Business

A one-hour workshop on seeing where your business is headed: the difference between a short-term cash forecast and a long-term projection, the three steps to a 12-month projection you can trust, and how to test a big decision before you make it.

Presented by Alex Engar · CEO Finance Academy · 59 minutes

The Short Answer

A 12-month financial projection shows what should be in your bank account each month a year from now. To build one you need three things: your gross margin on each thing you sell, a map of your overhead and debt payments by month, and two or more years of revenue trends by month. Put them together and you can see the months that will be tight, and test what a new hire, a raise, or a big purchase would do before you commit.

1

Know your gross margins

For each of your main revenue streams, what does it really cost to make one sale?

2

Map overhead and debt

What goes out every month, what goes out a few times a year, and how much goes to loan principal?

3

Check your trends

When are your busy and slow months, and is each revenue stream growing or shrinking?

Forecast vs. Projection

People often lump these together, but they answer different questions. A forecast is like a weather forecast: what's likely in the next week or two based on current conditions. A projection is like knowing Orlando will be hot in August: you don't know the exact temperature, but you know the pattern.

What goes into a short-term forecast

Cash in the bank today
− What you owe: payroll, bills, card and loan payments, and when each is due
+ What you're owed: receivables, and when you'll really collect them
+ New sales you expect to collect
= Where your bank balance is headed

Don't take your receivables report at face value. Invoices 60 or 90 days past due may never come in. Score each one by how likely and how soon you'll collect it. And separate what's automatic, like payroll and loan payments, from what you control, like paying down a line of credit or asking a supplier to wait a week. Our 13-week cash flow forecast workshop walks through building one.

Step 1: Know Your Gross Margins

List your 10 or fewer main revenue streams, like service lines or product categories. A candle company might use “wholesale” and “direct to consumer” rather than 50 scents. Then, for each one, add up everything it costs to make a single sale:

  • Materials or product cost
  • Direct labor
  • Marketing and sales commissions
  • Card processing fees
  • Shipping, fuel, equipment wear, disposal fees, or anything else specific to delivering it
Gross margin = (Sale price − Cost to deliver) ÷ Sale price
Example: ($100 − $40) ÷ $100 = 60%

This matters because when you plan to grow 10% or 30%, your costs grow with it. A projection that adds revenue without adding the costs that come with it will look far better than reality. A trucking company, for instance, needs to count driver time, fuel, repairs and maintenance, the trucks themselves, and dump fees on each type of load.

Step 2: Map Your Overhead and Debt

Labor overhead

Admin and office staff, and anyone not directly delivering what you sell.

Monthly overhead

Rent, utilities, insurance, software: what goes out every month.

Non-monthly costs

Quarterly insurance, annual licenses, December bonuses. Averaging these hides the months they make tight.

Debt principal

Your P&L shows loan interest but not principal, so a profitable P&L can hide thousands a month going out the door. Map every card, loan, line of credit, and cash advance payment.

In one client's numbers, about $16,000 a month was going to loan principal that never showed up on the P&L. That's exactly the gap behind “my P&L says I'm profitable, so where's the money?”

If your books aren't clean

This step needs trustworthy numbers, and most owners we start with have some cleanup to do. You don't have to fix every transaction first. Bank data and your point-of-sale or sales system can rebuild your margins and costs, and they double as a check on your books. Just don't keep putting it off. It's much easier to deal with now than when it's screaming for your attention.

Step 3: Check Your Trends

Look at revenue by month, by revenue stream, for at least two years. You're looking for three things: seasonality, whether each stream is growing or shrinking, and recent changes that will carry forward. If your work is lumpy, like building homes, look at it project by project instead.

Trends change decisions. If your slow season starts in July, you know how much needs to be in reserve by June to get through it. And if you run a trucking business whose slow season starts in August, August is a bad month to buy a new truck, even though that's hard to see when you're in the weeds.

Putting It Together

Bank balance at the start of the month
+ Cash in (from your trends and margins)
− Cash out (direct costs, overhead, debt, owner pay)
= Bank balance at the end of the month, carried forward 12 months

Draw a line at the lowest balance that still lets you sleep at night. We call it the “oh crap” line. Then you can see which months will dip below it and plan for them, instead of finding out when they arrive. It won't be a perfect crystal ball, but it's your best realistic picture.

Test decisions before you make them

This is where projections pay for themselves. Say you're thinking about a hire at $5,000 a month. Add the cost starting the month they'd start, and the balance stays fine until a dip in September. Then add what you expect them to bring in, say $15,000 a month starting four months after they're hired, and you can see whether the dip recovers. The same works for a raise, paying off a loan, or a big purchase.

For businesses that bill and collect on different schedules, like construction, the projection can account for how much you typically collect in 0 to 30, 30 to 60, 60 to 90, and 90+ days, and for direct costs that land a month later. Then you can adjust the year's revenue target up or down and immediately see what it does to your cash.

The Confidence Formula

What owners are really after is confidence: knowing what needs to be done, how to do it, and trusting yourself to do it.

Confidence = (Clarity × Margin × Buffer) ÷ Complexity
  • Clarity: knowing where you are, where you're going, and how to get there.
  • Margin: having money and time left over every month.
  • Buffer: reserves to absorb a bad month.
  • Complexity: more of it lowers confidence. Simple systems and one clear priority raise it.

Pick the one you're weakest on and start there, rather than trying to fix everything at once.

“AI is like a really smart five-year-old. It will tie its shoes and be incredibly confident about it, but did it superglue them?”

Alex Engar, on using AI for financial forecasts

Can AI build my projections?

AI is a useful tool for formulas and analysis, but we don't trust it with forecasts or financial decisions yet. It makes assumptions you can't see, it treats messy books as truth, and the result looks convincing whether it's right or not. It also can't give you the understanding you need to adjust the plan when something changes. Use it, but double-check everything, and make sure a human who knows your business has looked at it.

From gut to GPS

Today we're going from gut to GPS: how to look at the future of your business with clarity and confidence, and feel like you know what you're doing when you think about where you're headed. A lot of owners feel like there's so much going on they can't wrap their heads around the future, let alone what happened last year. We'll look at the confidence formula and exactly what goes into projections. Some of this may feel overwhelming. That's fine. Pick the one thing that makes the most sense to focus on next, rather than leaving with a list of everything and going back into paralysis.

Wouldn't it be incredible to know how much cash is likely to be in your bank account a year from now? Or what happens to your cash if you make the next hire, raise your own salary, pay down a debt, or make an investment? Most owners have no model for thinking about that. And even better if it's visual. Yesterday I walked a client through their model, hit two buttons, and a chart came up. I asked what story it told, and in five seconds he said his business looked really good a year from now.

Every business comes down to two levers: margins and cash timing. A good CFO or finance team adapts the model to your business specifically.

The confidence formula

After working with hundreds of business owners, what they want most is confidence: I know what needs to be done, I know how to do it, and I trust myself to do it. Confidence comes from clarity, times margin, times buffer, divided by complexity. Clarity means I know where I am, where I'm going, and how to get there. Margin means having extra left over every month, in both time and money. Buffer means reserves, so a bad month doesn't sink you. And more complexity means less confidence. If I know what to focus on and have systems guiding my decisions, my confidence goes up. Which of those are you most lacking?

Forecast vs. projection

I minored in meteorology, so here's the weather version. A forecast tells you what's likely over the next week or ten days based on current conditions. A projection tells you that Orlando in August will be hot, from historical averages. A forecast is short term, usually one to three months of weekly cash flow, and can be highly accurate, but it's volatile if you don't understand the variables. A projection is long term, one to two-plus years, based on assumptions and trends.

For a forecast, you need four things: how much is in the bank, how much you owe, including payroll, overhead, card payments, and lines of credit, how much you're owed, and how much you're likely to sell. And for each one, when. Most owners stay on top of the bank balance, but don't know what they owe when. Checking the bank account gives you a false sense of security. It's one slice of the picture.

Your accounts receivable might be recurring revenue for a software company, purchase orders for a manufacturer, or insurance billing for a physical therapy practice. Don't take your accounting software's receivables summary at face value. If there's old receivables in the 60, 90, or 91-plus day buckets, you don't know when that's coming in. We assign a score to each one for when it's likely to come in and how likely it is. We also automate as much as possible, because a manual forecast blows up every time you make a decision that wasn't in it. Expenses come out on the days they actually leave the account: loan payments, direct labor, overhead labor, distributions. Then the things you control in a cash crunch, like whether to pay down the line of credit this week or push a supplier a week, are manual.

Can AI do this for me?

It will try, and it will look really convincing. I put a similar scenario into ChatGPT and it gave me a wall of numbers. There's some directional correctness, but how useful is it to stare at as an owner? It makes a ton of assumptions, and we don't know what they are or how accurate they are. It's only as good as the data you give it, and about 80% of the clients we work with have some degree of messiness in their books. Feed it wildly off numbers and it takes them as truth. I love AI and use it behind the scenes all the time, and I've been trying to make it do financial modeling for years. But for these decisions, it tends to be wildly confident in highly volatile variables, and it can't transfer understanding. Right now we still need human conversations, with AI as a tool and a lot of double-checking. It's like a really smart five-year-old proudly showing you its tied shoes. Did you superglue those?

Step 1: gross margins

List your top 10 or fewer buckets of income: a service line, or a category of products. We have a candle company with 50 scents, but we group them into wholesale and direct to consumer. Then ask how much it takes to produce a single sale of each: materials, direct labor, maybe marketing, sales commissions, card processing fees, shipping. Most owners are fairly confident in the cost of goods on their P&L, but haven't factored in marketing, commissions, processing, or the equipment it took to build things in the first place.

Gross margin is what you sell it for minus what it costs to deliver, divided by what you sell it for. Sell something for $100 that costs $40 to deliver, and that's $60 of gross profit, a 60% gross margin. Without this, projections fall apart. Owners say they'll grow 10% or 30% this year, but if the projection doesn't scale up the costs that come with more sales, it's wrong. For a home services business, that might be roofs, siding, and fencing. For manufacturing, materials, direct labor, and equipment costs spread over five years. For trucking, driver time, fuel, repairs and maintenance, the trucks themselves, and dump fees.

Step 2: overhead and debt

Look at labor overhead, like admin and office staff; monthly overhead, like rent, electricity, and insurance; and non-monthly planned costs, like quarterly insurance or annual licenses. Most projections average expenses and forget the seasonal variability, so the projection looks great when a certain month is really going to be tight. If you give bonuses in December, plan for it.

You need clean books to do this well, and many businesses have cleanup to do. Even owners doing a million or more often have a bookkeeper split between payroll, bills, and the books, or an outside firm with 15 other clients. It starts with taking ownership: if something you delegated isn't right, you need to address it. If the books aren't clean, there's still plenty we can do with bank access or your point-of-sale data, which is also a great check on the books. This morning we finished a business's margins down to the dollar without touching their books.

It takes time. But shutting down your business, lying awake at 2 a.m., or telling an employee they no longer have a job takes a lot more. Don't wait until this is screaming for your attention and you're deciding which vendor you can't pay so you can make payroll.

Then debt. You pay interest, which may show on your P&L, and principal, which never does. So your P&L can say you're profitable while the money sneaks out the back door to debt principal, especially with merchant cash advances paid weekly. For every card, line of credit, and loan, figure out how much goes to principal each month, or each week if you're in a crunch. In one example, $16,000 a month was going to principal that didn't show on the P&L.

Q&A: two different businesses

If you have two separate companies, you usually want two sets of books. If they operate the same way in two locations, you might combine them for analysis. If they're very different, like landscaping and a beauty business, do each one separately. Start with whichever is easiest, or whichever makes or costs you the most, and build the muscle memory. Then combine the projections to see how you're doing overall. We have a client with six very different businesses combined so the owner's pay stays consistent even when one business has a down month.

Step 3: check your trends

Look at history by revenue stream, by month, ideally for two years or more, so you see real trends. Lawn care might be slow in January. Beauty products might spike in November and December. For lumpy businesses like home building, look per project instead. You want to know: do I have seasonality, am I growing or shrinking, and what recent changes are affecting me?

Seeing it laid out changes decisions. If your slow season, when you're burning cash, runs July through January, you set a target for how much needs to be in reserve by June. And if you run a trucking business and ask whether to buy a new truck in August, the start of your slow season, the answer is obvious once you see it. It's just hard to see the forest for the trees when you're in the weeds.

Putting it together

Know your gross margins, map your overhead and debt, and check your trends. Then it's simple: what's in the bank to start, what comes in, what goes out, and what should be in the bank each month for the next year. Draw an “oh crap” line, the balance below which you won't sleep well. Then you can see, for example, that December and especially April will be tight, and decide what to do about it. It's not a perfect crystal ball, but it's the most likely reality based on your business.

Then you can test what-ifs. Say you want to hire someone at $5,000 a month. Add it, and you're fine until September. But if that person will bring in $15,000 more revenue a month starting four months after they're hired, add that, and you can see whether it works. That's the confidence to hire, invest, or pay yourself a certain amount, because you know what's likely to be in the bank six months from now.

For a construction client, billing happens on an accrual basis but collections happen differently, so we model how much comes in within 30 days, 30 to 60, 60 to 90, and 90-plus, and direct costs that come in a month later. Then we can adjust the year's revenue target down to something more realistic and immediately see the effect: they'll be a little tight for a few months, still above their line, and fine after that.

Frequently Asked Questions

A forecast looks one to three months ahead, week by week, using what's in the bank, what you owe, what you're owed, and expected sales. It's for managing cash in the near term. A projection looks one to two years ahead, month by month, using your margins, overhead, debt, and historical trends. It's for big decisions like hiring, investing, and setting reserves.

Work out the gross margin on each of your main revenue streams, map your overhead and debt payments by month, including non-monthly costs and loan principal, and review at least two years of monthly revenue trends. Then start with today's bank balance and add expected cash in and subtract expected cash out, month by month, for 12 months.

A common reason is loan principal. Your P&L may show interest, but principal payments on loans, lines of credit, and cash advances never appear there, even though they take real cash every month. Owner distributions, tax payments, and slow-paying customers add to the gap. A projection that includes them shows where the money actually goes.

It can help with formulas and analysis, but we don't recommend relying on it for forecasts or decisions yet. It makes assumptions you can't see, it takes messy books at face value, and its output looks convincing whether it's right or not. Double-check everything and have someone who knows your business review it.

Ideally two years or more of monthly revenue, broken out by revenue stream, so you can see seasonality and real growth trends. If your work is lumpy, like large construction projects, project-level history is more useful than monthly totals. If your books aren't clean, bank and sales system data can fill the gaps.
