Subway is one of the most affordable QSR franchises to open — total startup costs run $150K–$450K. Here's the full cost picture and how financing typically works.
Subway is the world's largest fast-food chain by location count — and one of the most accessible QSR franchises from a capital standpoint. Lower build-out costs (inline strip-center formats rather than freestanding pads), a recognized brand, and relatively modest net worth requirements make Subway one of the more entry-level franchise opportunities in the restaurant sector. Subway has been in an active brand-refresh and menu-modernization cycle, with new ownership investing in marketing and store renovation programs. This guide is for prospective Subway franchisees evaluating the financing requirements.
Per Subway's current FDD, total estimated initial investment for a traditional inline location runs approximately $150K–$450K. Subway locations are overwhelmingly inline (strip centers, food courts, convenience stores) rather than freestanding pads, which is the primary reason startup costs are lower than most QSR competitors. Major cost categories include:
Subway charges an 8% royalty on gross sales — one of the higher royalty rates in QSR franchising. The advertising fee is 4.5% of gross sales, for a combined ongoing fee load of 12.5%. This is a notable consideration in pro-forma underwriting: while the entry cost is low, the ongoing fee burden is high relative to competitors. Franchisees should model whether the unit economics pencil out in their target market given the 12.5% off the top.
Subway's net worth and liquid capital requirements vary by territory but are generally in the $30K–$90K range — significantly lower than most QSR franchise systems. This accessibility is part of how the chain scaled to tens of thousands of locations globally. That said, lenders (not just the franchisor) will apply their own underwriting standards, and SBA lenders typically want to see the borrower contributing at least 10–20% of the total project cost in equity.
Subway is listed on the SBA Franchise Directory, qualifying franchisees for SBA 7(a) financing. Given the relatively modest total investment, some borrowers also use conventional bank loans or SBA Microloan Program funds (up to $50K) for smaller build-outs. Key financing levers:
Subway is on the SBA Franchise Directory, so SBA-approved lenders can use expedited eligibility review rather than submitting the franchise agreement for individual SBA review. At $150K–$450K, this is a mid-to-low investment deal — but lenders still apply standard SBA underwriting criteria. Key factors:
For smaller Subway builds ($150K–$250K), SBA 7(a) is the dominant structure — the loan size is within efficient SBA processing range and the assets (equipment, leasehold improvements) serve as collateral. For operators opening multiple locations, consider whether a single larger credit facility covers multiple units more efficiently than separate loans per store. Subway's inline format means SBA 504 (which requires owner-occupied real estate) is rarely applicable — the landlord, not the franchisee, owns the building.

The current FDD shows total estimated initial investment of $150K–$450K for a traditional inline Subway location. Costs vary based on market, location type, and renovation scope. High-rent markets and non-traditional locations (airports, hospitals) can push costs higher.
This guide covers financing costs, not investment advice — and franchise ROI depends heavily on location, execution, and local market conditions. Any prospective franchisee should review Subway's FDD Item 19 (financial performance representations) carefully and consult with an independent franchise attorney and CPA before investing.
Because Subway is on the SBA Franchise Directory, the franchisor eligibility review step is expedited. Total processing from complete application to funding typically runs 30–60 days for SBA 7(a) loans. Start the financing process before signing the franchise agreement.
Subway's net worth thresholds are among the more accessible in QSR franchising — typically $30K–$90K depending on territory. Your lender will independently assess your financial strength as part of loan underwriting.
SBA guidelines set a minimum DSCR of 1.15× — the business must generate $1.15 in cash flow for every $1.00 in annual debt service. Most SBA lenders apply 1.25× or better in practice. For Subway, the 12.5% combined royalty and ad fee load is a significant deduction from gross sales — the pro forma must accurately model net cash flow after these fees when calculating DSCR.

SBA requires a minimum 10% equity injection on the total project cost — on a $250K Subway build, that's $25K from the borrower's own verifiable funds. Some lenders require 15–20% depending on the borrower profile. Funds must be the borrower's own (not borrowed from a HELOC or personal loan).
