Subway FDD Review: What Franchise Buyers Need to Know in 2026
Meta Description: Subway FDD review: turnaround story under new ownership, declining unit counts, low entry cost but high fee burden. What the numbers say before you invest.
You're looking at a Subway franchise and wondering whether the turnaround is real. The brand has new ownership, a refreshed menu and a remodel program underway. But it also has a decade of declining store counts behind it. The FDD tells you which story to believe.
Here's the honest assessment. Also see our quick Subway risk analysis in our FDD library.
What Is the Subway Franchise?
Subway is the world's largest restaurant chain by unit count, a sandwich-focused QSR founded in 1965 in Bridgeport, Connecticut. At its peak, Subway operated more than 27,000 US locations. That number has declined significantly over the past decade, falling below 21,000 as underperforming stores closed or were not renewed.
In 2023, Roark Capital acquired Subway in a deal reportedly valued at $9.55 billion. This marked the end of the founding family's control and the beginning of a corporate-backed turnaround effort. Under new ownership, Subway has launched menu innovations (the Subway Series pre-built sandwiches), a mandatory store remodel program and operational standardization efforts aimed at improving consistency and unit economics.
The franchise operates in small-footprint locations (typically 800-1,400 sq ft), with a model built around sandwich assembly with minimal cooking equipment. Labor requirements are relatively low compared to full-kitchen QSR concepts. The brand's challenge is not cost structure but revenue generation: too many locations in too many markets were producing insufficient sales to sustain viable businesses.
Key FDD Findings
The Turnaround Is Real but Unfinished
Subway under Roark Capital is a fundamentally different proposition than Subway under the DeLuca family. The new ownership has brought private equity operational discipline: standardized menus, mandatory remodels, technology upgrades and a more selective approach to new franchisee approvals. Early indicators suggest remodeled locations are seeing meaningful sales lifts, often 20-30% over pre-remodel baselines.
But here's the caveat: the turnaround is still in its early stages. The remodel program is expensive ($150,000-$300,000+ per location), and not all existing franchisees can or want to fund it. The system is still losing net units. Until the store count stabilizes and same-store sales growth is sustained over multiple years, this remains a turnaround bet, not a proven success story.
Compare Subway's trajectory with Jersey Mike's, which has been growing consistently without needing a turnaround narrative.
The Fee Burden Is Higher Than Most Buyers Expect
Subway's combined fee obligation is 12.5% of gross sales: an 8% royalty plus a 4.5% advertising contribution. That is among the highest combined rates in QSR. At a $400,000 AUV (which many Subway locations produce), you're paying $50,000 per year in fees alone, before rent, labor, food costs or debt service.
The 8% royalty is particularly notable. Most QSR brands charge 4-6%. Subway justifies it partly through the low initial investment and small-footprint model, but the impact on operating margins is real. At lower revenue levels, a 12.5% combined fee structure makes profitability extremely difficult.
Item 20 Tells a Complicated Story
Subway's Item 20 data is the most important section of the entire FDD. The raw numbers show thousands of closures over the past five years. That is not a normal pattern for a healthy franchise system. However, the pace of closures has been slowing, and recent data shows a more selective approach to new openings.
What to look for in the data:
- Net unit change by year. Is the bleeding stopping? Look at the trend line, not just the absolute number.
- Terminations vs. non-renewals. There's a meaningful difference between a franchisor terminating underperformers and franchisees choosing not to renew. Both are happening at Subway, for different reasons.
- New openings by market type. Where is Subway adding stores? If new development is concentrated in strong markets while weak markets continue losing locations, that's actually a healthy rebalancing.
The Fee Math
Subway's fee structure:
- Royalty: 8% of gross sales
- Ad Fund: 4.5% of gross sales
- Combined: 12.5% of gross
At $400,000 annual revenue (below-average location):
- Royalties: $32,000
- Ad fund: $18,000
- Total fees: $50,000/year
At $600,000 annual revenue (stronger location):
- Royalties: $48,000
- Ad fund: $27,000
- Total fees: $75,000/year
At $400K revenue with $50,000 in fees, $3,500-$6,000/month rent, $8,000-$12,000/month labor and 28-32% COGS, the margins are razor-thin. The business only makes sense at revenue levels well above the system's weaker performers. That makes your location selection arguably the single most important decision in this process.
Red Flags to Watch For
1. The remodel mandate is a forced capital expenditure. If you're acquiring an existing location, understand the remodel timeline and cost. A $200,000 remodel on top of your acquisition price changes the total investment math significantly.
2. Fee burden at low revenue levels is punishing. At 12.5% combined fees, a Subway doing $350K in revenue is paying $43,750 before any operating expenses. Model your breakeven carefully and be honest about the revenue your specific location can realistically generate.
3. Brand perception recovery takes time. Subway spent years dealing with quality inconsistency across its massive system. The new menu helps, but changing consumer perception of a 20,000+ location brand takes years, not months. Factor in a multi-year timeline for the brand lift to fully materialize.
4. Over-saturation in many markets. Despite closing thousands of locations, many markets still have more Subway stores than the demand can support. Before signing, map every Subway within a 3-mile radius of your target location and assess realistic trade area overlap.
5. New ownership means new priorities. Roark Capital is a private equity firm. Private equity ownership typically comes with a defined investment horizon (5-10 years) and a focus on profitability metrics. Understand that the strategic direction of the brand could shift again when Roark eventually exits.
