Money used to win championships in Formula 1. Simple as that. If you were Ferrari or Mercedes back in 2018, you just threw $400 million at the car until it went faster. Smaller teams like Haas or Sauber? They were basically racing in a different zip code.
Then came 2021.
The Formula 1 budget cap changed everything. It wasn't just a rule change; it was a total lobotomy of how the big teams operate. Suddenly, Christian Horner and Toto Wolff had to care about the price of a front wing endplate. Imagine going from an unlimited black card to a strict monthly allowance. It's messy. It’s complicated. And honestly, it’s the only reason the grid isn’t three seconds apart right now.

The $135 million myth
Everyone looks at the "base" number and thinks that's the whole story. For 2026, we're looking at a baseline of roughly $135 million, adjusted for inflation and the number of races. But it’s not a hard ceiling on total spending. Not even close.
F1 is a business of loopholes. You've got "Excluded Costs" which are basically the giant elephant in the room. Driver salaries? Not included. The three highest-paid employees? Not included. Marketing, travel, and hospitality? Nope. You could spend $50 million on Lewis Hamilton’s contract and it doesn't touch the cap. You could fly the whole team business class to Las Vegas and it’s "free" money in the eyes of the FIA.
What the Formula 1 budget cap actually targets is performance. It’s about the carbon fiber, the wind tunnel hours, the CFD (Computational Fluid Dynamics) simulations, and the guys in the garage. If it makes the car go "vroom" faster, it's probably capped.
Why the Red Bull "Catering" drama actually mattered
Remember the 2021 breach? Red Bull went over by about $2.2 million (or 1.6% if you’re being precise). They blamed it on tax credits and, famously, catering costs. People laughed about sandwiches, but in a sport where a 0.1% gain in aero efficiency can mean pole position, $2 million is a fortune.
That money pays for extra floor iterations. It pays for a lighter gearbox casing. When the FIA slapped them with a $7 million fine and a 10% reduction in wind tunnel time, it was a signal: the era of "oops, we overspent" is dead.

How the big three had to diet
Before the cap, Mercedes, Red Bull, and Ferrari were bloated. They had hundreds of staff members whose only job was to find a thousandth of a second. When the Formula 1 budget cap hit, they had to fire people. Or, more accurately, "redeploy" them.
- Applied Sciences: This is the new buzzword. Mercedes and McLaren now have entire divisions dedicated to high-performance cycling or America's Cup sailing. Why? Because you can keep your best engineers on the payroll without their salaries hitting the F1 cap.
- The "Used Parts" Market: Teams used to throw away parts after one race. Now? They patch them up. You’ll see mechanics literally carbon-wrapping a cracked floor because they can't afford to bake a new one in the autoclave.
- Efficiency over Excellence: In 2019, if a part was 2% better but cost $500k to make, you made it. Today, you might skip it. The opportunity cost is too high.
The 2026 shakeup and the new financial regulations
The FIA just released the framework for the 2026 regulations. The cap is staying, but it’s evolving. We’re moving toward a $215 million "total" cap for engine manufacturers (Power Unit Manufacturers). This is huge.
Audi is coming in. Ford is partnering with Red Bull. Honda is sticking around with Aston Martin. These giants aren't just building engines; they're building financial structures to hide R&D. The FIA’s financial auditors—led by Federico Lodi—are basically the most powerful people in the paddock now. They don't look at lap times; they look at spreadsheets.
The 2026 Formula 1 budget cap will also have to account for the massive infrastructure projects. Aston Martin just built a brand new "smart" factory. McLaren finally got their new wind tunnel online. Under the rules, "Capital Expenditure" (CapEx) is limited. You can't just buy a $100 million simulator to bypass the wind tunnel restrictions. There’s a sliding scale based on where you finished in the standings, which is supposed to help the backmarkers catch up.
Real talk: Is it actually working?
Yes and no.
Look at the gaps. In the "glory days," the gap from P1 to P20 was often four or five seconds. Now, in Q1, we often see the entire field separated by less than 1.2 seconds. That’s the cap working. It prevents the "spending arms race" that killed teams like Force India and Manor.
But there's a downside.
If you mess up your car design at the start of the year—like Mercedes did with the "zero-pod" concept—the Formula 1 budget cap makes it almost impossible to fix. You can't just build a "B-spec" car mid-season because you don't have the cash left in the budget. You’re stuck with a tractor until next year. It punishes mistakes more than it rewards brilliance.
Also, the "Rich Team" advantage hasn't vanished; it just changed shape. The top teams still have the best heritage, the best tools already paid for before 2021, and the most prestige to attract sponsors.
The hidden cost of the cap: Personnel burnout
Engineers are the unsung victims here. Since their salaries are capped, but the calendar is expanding to 24 races, the "per-hour" value of an F1 mechanic is actually dropping.
Top-tier talent is starting to look at Silicon Valley or even Formula E. Why work 80 hours a week for a capped salary when you can go to Apple for double the pay and zero jet lag? F1 is currently terrified of a "brain drain."
Tracking the money in 2026
If you want to understand who will win the next era, stop looking at the drivers. Look at the "Financial Transparency" filings.
The FIA uses a portal where every single invoice is uploaded. Seriously. If a team buys a pack of zip ties, it goes into the system. The auditors can show up at a factory in Milton Keynes or Maranello at any time and demand to see the books. It's forensic.
The biggest challenge moving forward is "Related Party Transactions." This is when a team like RB (the junior Red Bull team) buys parts from Red Bull Racing. How do you value a front suspension? If Red Bull sells it to them for $1, that’s cheating. If they sell it for $1 million, it’s fair. Setting these "Fair Market Value" prices is the new frontline of the F1 war.
What you should watch for next
To see how the Formula 1 budget cap is affecting the race in real-time, pay attention to the "Upgrade Packages" brought to the European rounds.
- Count the bits: If a team brings a new front wing, look at whether both drivers get it. If only one does, they’re likely hovering at the edge of their budget.
- The Crash Tax: Every time Logan Sargeant or Sergio Perez bin a car into a wall, that’s roughly $500k to $1 million gone. That isn't just repair money; that is money taken directly away from the development of the 2026 car. Crashing is now a strategic disaster.
- The "Big Leap" teams: Watch Aston Martin and McLaren. They are the "middle class" teams that are using the cap to punch up. They don't have the baggage of 2,000 employees, so they can be more agile with their $135 million.
The Formula 1 budget cap has turned the sport into a giant game of Resource Management. It’s less "The Great Race" and more "The Great Accounting Audit." But honestly? It's the only way the sport survives the next decade without becoming a one-team parade.
For fans, the best way to stay ahead is to keep an eye on the FIA's Financial Regulations documents, which are updated periodically. Understanding the difference between "Operational" and "Capital" expenditure will give you a much better idea of why your favorite team is—or isn't—bringing a new floor to Silverstone. Check the official FIA "Cost Cap Administration" summaries released every September; that’s when the real winners and losers of the spending war are actually crowned.
