Subway Franchise Cost 2026: Cheapest QSR, Biggest Risk?

Subway is the largest franchise system in the United States by unit count. It is also one of the most troubled. The 2025 FDD paints a picture of a system in contraction: 19,502 locations, down from 20,576 just two years ago, with 1,075 closures in a single year and a turnover rate of 5.5%. Before you write a check, you should understand what those numbers mean for anyone buying in today.

The cost looks cheap. That is the trap.

A Subway franchise costs $238,625 to $536,745 to open, including a $15,000 franchise fee. By QSR standards, that is remarkably affordable. The average QSR franchise in our database requires $327K to $860K. Subway's low end undercuts even the average low end by about $90,000.

Here is the thing though: cheap to buy does not mean cheap to operate. Subway charges an 8% royalty on gross sales plus a 4.5% advertising contribution. That is 12.5% of every dollar you bring in going straight to corporate before you pay a single employee or buy a single ingredient. For a QSR system where the category average royalty sits around 5.4%, Subway's fee load is punishing.

What Subway will not tell you about revenue

Subway does not disclose Item 19 financial performance data. That is the section of the FDD where franchisors can share what their units actually earn. Out of 443 QSR franchises in our database, the majority provide at least some revenue data. Subway provides none.

When a franchise system with 19,502 locations chooses not to disclose revenue or profit data, that is not an oversight. It is a deliberate decision. The absence of Item 19 means you cannot validate any ROI assumptions with verified data. You are flying blind.

Industry estimates (not from Subway's FDD) suggest average unit volumes in the $400K to $500K range. If accurate, that puts the 12.5% fee load at $50K to $62K per year going to Subway corporate. On a store doing $450K in gross sales, after food costs (~30%), labor (~25%), rent (~10%), and the 12.5% royalty-plus-ad fee, the owner might clear $30K to $50K per year. That is not a business. That is a job that costs you half a million dollars to buy.

The investment breakdown (Item 7)

The relatively low equipment cost reflects Subway's simple operational model: no fryers, no grills, no drive-through infrastructure. That simplicity keeps initial costs down but also limits menu complexity and average ticket size compared to competitors like Wingstop or Popeyes.

5,097 SBA loans tell a mixed story

Subway has more SBA 7(a) loans on file than almost any other franchise brand: 5,097 total. The overall charge-off rate is 6.8%, with 324 defaults. The 5-year default rate is 2.4%.

For context, the QSR category average default rate is 6.8%, so Subway sits right at the category line. Not terrible, but not the performance you would expect from the world's largest franchise. Compare that to McDonald's at 0.0% across 1,247 loans or Chick-fil-A at 0.0%.

The shrinking footprint

The FDD's Item 20 tables are where the real story lives. Subway went from 20,576 franchised units to 19,502 over three years. That is a net loss of 1,074 locations. The system is shrinking by roughly 2% per year.

Why? Subway closed 444 outlets and had 1,075 terminations, non-renewals, or transfers in the most recent disclosure year. When you see closures outpacing openings by that margin, it signals that existing operators are either struggling with profitability or choosing not to renew.

Roark Capital acquired Subway in 2023. Private equity ownership typically means a focus on fee extraction and margin optimization in the near term. The franchise fee dropped (it was $15K, now ranges $7.5K to $15K), and the system is being restructured. Whether that restructuring helps individual franchisees or mostly benefits the parent remains to be seen.

No territory protection

Buried in the franchise agreement: Subway does not provide exclusive territory protection. Your franchise agreement gives you a location, not a market. Subway can open another location across the street, sell products through grocery stores in your area, or license another operator right next to you.

This is particularly brutal for a system with 19,502 locations. In most metro areas, Subway locations already cannibalize each other. Adding another $238K investment into a market without any guarantee that the franchisor will not saturate it further is a significant risk. Check our Subway profile for the full red flag breakdown.

The 20-year term is unusually long

Subway locks franchisees into a 20-year initial term with 20-year renewals. That sounds like stability, but in practice it limits your exit options. If the system continues declining, you are contractually bound to a brand losing market share. The franchise agreement includes a non-compete of 1 year and mandatory arbitration, which tilts dispute resolution in the franchisor's favor.

The ongoing fees add up fast

• Royalty: 8% of gross sales. This is above the QSR average of ~5.4%. On estimated revenue of $450K, that is $36,000 per year.
• Advertising fund: 4.5% of gross sales. Another $20,250 per year at $450K revenue.
• Technology fee: $75/month. Relatively modest compared to other systems.
• Transfer fee: $7,500. If you try to sell your location, Subway takes a cut.

84 litigation matters

The 2025 FDD discloses 84 litigation matters. That is a high number and includes wrongful termination claims, breach of contract disputes, and allegations of fraudulent inducement. A large franchise system will always have some litigation, but the nature of these cases, particularly the termination and breach claims, suggests ongoing friction between Subway corporate and its operators.

The bottom line

Subway is cheap to buy and expensive to operate. The 12.5% combined fee load, absent Item 19 disclosures, shrinking unit base, and lack of territory protection create a risk profile that does not match the brand recognition. If you have $300K to $500K to invest in a QSR franchise, there are systems with better unit economics, lower fee loads, and growing footprints. Compare options on our QSR screener before signing anything.

The one scenario where Subway might work: acquiring an existing high-performing location at a discount from a motivated seller. But even then, verify the trailing 12-month P&L independently, because Subway will not give you system-wide data to benchmark against.
