The FP&A to CFO Career Path Nobody Trains You For
What the FP&A to CFO career path teaches: from intern at GM to CFO, the models that broke, and why the job was never building the plan.
Nobody trained me to be a CFO. My FP&A to CFO career path started as an intern at General Motors. By the time I left, I was CFO of a $1B business. No six months of onboarding. No playbook. They threw me at problems and let me figure it out. When I couldn’t, I learned fast.
The FP&A to CFO career path starts with no playbook
That’s still how I operate.
So now I do the same with my team. Real problems, real stakes, real support when things break. Some thrive. Some struggle and get there with help. The ones who make it grow faster than any training program could.
Here’s the uncomfortable part. Training is important, but training can become hiding. A reason to stay comfortable while the work waits.
80% done now beats 100% done in a year. Every time.
High tolerance for failure. Low tolerance for staying where I am.
The ladder is gone
I started as an intern at GM in 2008. By 2016 I was CFO of a billion-dollar business.
Nobody trained me for that job. I just built models. Hundreds of them. Most were wrong. Some were beautiful and wrong, which is worse.
That was the apprenticeship. Not a curriculum. A thousand small failures with real consequences.
Then I spent the next decade automating every bit of it. At Expedia we took forecast accuracy from 85% to 99%. Then we cut the close from 15 days to 5.
I wouldn’t undo a single automation. I also wouldn’t be in this seat without those years of doing it by hand.
The CFO role isn’t disappearing. The ladder to it is.
So if you’re building a finance team today, or starting out in finance today, I have one real question: how do you develop judgment when the work that used to build it is done by a machine?
I genuinely don’t know.
The Excel gets you in the room. The judgment keeps you there
Early in my career, I thought being great at FP&A meant being great at Excel.
Faster formulas. Cleaner models. More tabs than anyone else on the team.
I was wrong.
I taught myself modeling the hard way, by trial and error. Built hundreds of models. Broke most of them. And somewhere in there it clicked: the spreadsheet was never the job. It was the starting line.
Nobody remembers your VLOOKUP. They remember the call you helped them make.
The real work starts after the model runs:
- Turning the number into a decision the CEO can act on this week
- Catching the risk months before it shows up in actuals
- Saying “here’s what I’d do,” not just “here’s what happened”
A beautiful model that changes nothing is a waste. An ugly one that stops a bad decision earns its keep.
I still love a clean build. But I stopped confusing the tool with the work a long time ago.
If you’re early in finance and grinding on formulas, hear me: the Excel gets you in the room. The judgment keeps you there.
Advice to my younger self as a finance intern at GM
If I could advise my younger self as a finance intern at GM many years ago, here’s what I’d say:
“Knowing the numbers is good. Understanding how decisions actually happen, that’s better.”
The past few years taught me what textbooks never did. The pressure. The pivots. The late nights. The tradeoffs.
From intern to CFO, the real learning came from asking better questions, over and over again.
If I had to distill it down, here are 6 things I wish I knew sooner:
- Understand the business before building the model. A forecast built in a vacuum will always break under pressure.
- Spend more time listening to operators than perfecting reports. The real levers of performance live outside the spreadsheet.
- Don’t hide behind data. Interpret it. Your job isn’t to be precise. It’s to drive action.
- Learn to say, “I don’t know, but I’ll find out.” That line builds more trust than faking it ever will.
- Push for clarity, not complexity. Great CFOs simplify. They don’t make things harder than they need to be.
- Know when done is better than perfect. In high-growth companies, speed beats polish every time.
I hired a thinker. I’m paying for a librarian
One line from this year’s FP&A Trends Survey has stuck with me. A CFO told the researchers:
“I hired a thinker. I’m paying for a librarian.”
It landed because I’d already said it. Two years earlier, on a recorded call, I’d described my own team almost word for word: my reporting team keeps sending me reports, I keep giving feedback, and a few days later they come back with what I asked for. Retrieves on request. Iterates on feedback. Never shows up with the answer.
That’s a librarian. And here’s the part nobody wants to say out loud: it’s usually not a hiring mistake.
AFP and APQC surveyed 430+ FP&A professionals. Only 25% of their time goes to actual analysis. The other 75% is gathering data (42%) and administering process (33%). The job is built to be three-quarters retrieval. Of course you’re paying for a librarian. You designed a librarian’s week and hung a thinker’s title on it.
The tell is easy once you know it. A librarian says, “Gross margin dropped three points.” A thinker says, “Gross margin dropped three points because we’re discounting too early in the cycle, and Sales needs tighter approval thresholds above 15%.” One informs. One influences.
Here’s my confession. When I got tired of waiting for the thinker, I didn’t fix it. I pulled the dataset, loaded it into my own tools, and built the analysis myself. Faster, sharper, done. But I solved the task and skipped the leadership problem. I routed around the librarian instead of building a thinker.
If I had it back, I’d change the week before I changed the hire. Less retrieval on their plate, more time in the room where the decision actually gets made. You don’t get thinkers by interviewing harder. You get them by handing them something worth thinking about.
There’s no single path to the CFO seat
There’s no single path to the CFO seat. But every path shapes how you lead.
Some rise through deal-making. Some through operations. Some through accounting. Some through relationships.
Each one builds a different kind of CFO.
- The deal-maker. Comes from banking, consulting, or PE. Drives capital strategy, M&A, and board communication. Moves fast. Stays high-level. Sees the big plays.
- The FP&A and operations leader. Built their base in planning, ops, or corporate strategy. Understands how levers connect across the business. Deep in performance, forecasting, and resource alignment.
- The controller turned CFO. Grounded in accounting, audit, or compliance. Owns the details, builds trust, and strengthens internal systems. The foundation of financial accuracy.
- The client-centric advisor. Comes from wealth management, advisory, or investor relations. Strong communicator, high empathy, earns trust fast. Knows how to manage stakeholders and relationships.
The best CFOs pull from more than one path.
They blend execution, communication, and strategy.
They don’t just report numbers.
They shape what happens next.
The job was never building the plan
My successor asked me to list everything I do.
I’m handing off part of my role, so he wanted to get his arms around it. Simple request. Go through my inbox, write down what I’m actually responsible for.
I ran the exercise. I wasn’t happy with what it produced.
Because the honest answer isn’t a list. Close the books. Own the forecast. Run the reporting pack. Watch the cash. All true. All easy to write down. And all of it missed the point.
The finance functions aren’t the hard part. You can staff those. Put them on an org chart, hand someone the list, they’ll cover the bases.
What you can’t put on a list is the actual job. Making sure the plan happens once it’s written down.
Anyone can build the plan. The model’s done by Tuesday, the report goes out on the first. The hard part, the part nobody writes a job description for, is the follow-through. The chasing. Catching the thing before it slips.
That’s the job. Not the model. Not the report. The part that never makes the list.
My successor inherits the functions on day one. The rest of it is what I’m still figuring out how to hand over.
