How to Finance a Subway Franchise in 2026

Total estimated initial investment per the current FDD runs $150K–$450K. The range is wide because location format (new build vs. existing transfer), local build-out costs, and equipment condition vary significantly. Lenders evaluating a Subway franchise deal focus on:

• Equity injection: SBA requires minimum 10%; Subway's own net-worth thresholds run $30K–$90K depending on market. Document liquid assets — not HELOC or borrowed funds.
• Existing unit revenue (if acquiring): Lenders underwrite trailing 12-month gross sales and DSCR. A DSCR of 1.25x is a common floor.
• Build-out cost documentation: Lenders want a signed lease or letter of intent, contractor bid, and equipment list before committing.
• Operator experience: Prior food-service or retail management experience is viewed favorably — Subway requires franchisees to actively manage the business.
• Personal credit: 650+ FICO is a common threshold for Subway SBA deals; stronger credit drives better rate pricing.

SBA 504 is less commonly used for Subway's inline strip-center model because 504 requires owner-occupied commercial real estate — most Subway locations operate on leases. The SBA 504 program becomes relevant only if a franchisee is purchasing a freestanding location or a mixed-use building where the Subway occupies a majority of the space.

Subway maintains a preferred-lender network facilitated through FRANdata — a franchise intelligence platform that lenders use to assess franchise brand health, franchisee default rates, and disclosure data. Subway's preferred lenders have experience with the brand's FDD, territory rules, and multi-unit structures, which can shorten underwriting timelines. Subway does not operate a direct in-house lending program, but franchisee development representatives can direct candidates toward experienced lenders.

Subway is listed on the SBA Franchise Directory, and at $229K–$522K it sits in the range where both SBA 7(a) and SBA Express loans are viable structures depending on project size. Key underwriting factors lenders evaluate:

• DSCR and revenue modeling: Subway's AUV (average unit volume) is approximately $430K–$480K nationally (per Subway FDD Item 19, 2023). Lenders underwrite year-one DSCR conservatively — typically 60–75% of system AUV for new builds in untested locations. Existing franchise transfers are underwritten on trailing 12-month store P&Ls, which are more bankable than pro formas.
• Equity injection: SBA requires a minimum 10% equity injection. Subway deals typically see lenders accept 10–15% equity at the lower investment range ($229K–$350K), with SBA Express loan structures for smaller builds. Larger builds or multi-unit agreements may require 20%.
• Royalty load stress test: Subway charges 8% royalty + 4.5% advertising fund = 12.5% total fee load on gross sales — one of the higher combined rates in QSR. Lenders run DSCR with the full fee load applied before confirming the deal is serviceable at conservative volume assumptions.
• Lease quality and term: Subway requires a 20-year franchise agreement, so lenders verify the lease term (plus options) matches the loan term. Short remaining lease terms on existing locations are a material underwriting concern — lenders will not close SBA loans where the lease can expire before the note matures.
• Transfer vs. new build: Acquiring an existing Subway unit (transfer) is the preferred path for SBA lenders because trailing revenue data is available. New builds require a site feasibility analysis, and lenders scrutinize competition density, traffic counts, and proximity to anchor tenants.
