Franchise Royalties and Ad Funds: The Math That Compounds

Every franchise fee conversation starts with the initial investment number because it’s the biggest figure on the page. The number that actually determines whether the location makes money for the next five or ten years is smaller and recurring: the royalty rate, the ad fund contribution, and whatever technology or platform fees ride along with them. Get the initial number wrong and you overpay once. Get the ongoing rate wrong and you’re overpaying every week the doors are open.

These fees are disclosed in Item 6 of the Franchise Disclosure Document, and they’re some of the least dramatic-looking numbers in the whole document. A line that says “6% of Gross Sales” doesn’t look like much until you run it against a real month of revenue and see what’s left over for rent, labor, and food cost. That’s the math this article walks through, brand by brand, using rates pulled from actual FDDs and franchise fee summaries, not averages pulled from thin air.

We sell no franchise and take no referral fee from any brand named here. The job is to show you how the rate structures work so you can read your own Item 6 and Item 7 with the right questions ready, not to steer you toward or away from any specific system. Every figure below comes from an FDD or a named source disclosed in the sources list, not an estimate; see our editorial methodology for how we source and verify these numbers.

The three fee types stacked in Item 6

Item 6 of the FDD lists every fee a franchisor can charge beyond the upfront franchise fee, and in food and beverage concepts three categories do almost all the work.

Royalty. This is the core fee you pay for the right to keep operating under the brand, keep using the trademark, and keep receiving whatever ongoing support the franchise agreement promises. It is calculated on gross sales in the overwhelming majority of systems. Scooter’s Coffee charges 6.0% of gross sales, per its 2024 FDD data as summarized by franchiseinvestordata.com. Dunkin’ charges 5.9% of gross sales. Subway charges 8% of gross sales, per FDD Item 6 detail published by franchise law firm Lopes Law LLC. Toastique charges 6% of gross sales. None of these numbers move based on whether the location was profitable that month.

Ad fund, marketing fund, or brand fund. This is a separate percentage, paid on top of the royalty, that the franchisor pools across the system to pay for national or regional advertising. Dunkin’s ad fund runs 5% of gross sales on top of its 5.9% royalty. Subway’s advertising contribution is 4.5% of gross sales on top of its 8% royalty, again per Lopes Law LLC’s Item 6 breakdown. Caribou Coffee structures this as a marketing contribution of up to 3% of gross sales, split between a brand fund and a local marketing requirement, according to franchisechatter.com’s 2026 review of Caribou’s FDD. Toastique layers a 2% ad fund on top of its 6% royalty, then requires an additional 2% of gross sales in local marketing spend that the franchisee controls but must still spend, per fee detail published by vetmyfranchise.com.

Technology and platform fees. This is the newest fast-growing category, and it rarely gets the attention royalty rates get because the dollar amounts look small next to a percentage. The International Franchise Association’s FranConnect-sourced study found that 61.9% of franchisors now collect a technology fee, and 60.4% of those charge it as a flat monthly amount rather than a percentage of revenue. Quick Service Restaurant franchises carried a median tech fee of $168 a month in that study. Dunkin’s own technology fee for POS, mobile ordering, and digital platform access runs $154 a month per its 2025 fourth-quarter FDD filing, close to that industry median.

Percentage of gross, flat fee, and sliding scale: three different structures

Most food franchises use a straight percentage of gross sales for the royalty, which is what every brand named above does. Two other structures show up often enough that you should know how they behave differently.

Sliding scale royalties change the percentage as sales volume changes, usually dropping the rate as a location does more business. SERVPRO uses a graduated royalty that moves between roughly 3% and 10% of gross volume depending on the franchisee’s monthly sales tier and license type, on top of a separate 3% national advertising fund contribution, according to Lopes Law LLC’s breakdown of SERVPRO’s FDD Item 6. The appeal for the franchisor is obvious: lower rates reward the locations already succeeding, and higher rates apply to newer or smaller locations that may need more system support relative to what they’re generating. The appeal for you depends entirely on which tier you expect to sit in during your first two or three years, not your fifth.

Flat dollar royalties charge a fixed amount per week or month regardless of what the location sold. Anytime Fitness runs on this model: a flat monthly royalty reported at $820 per center in franchisechatter.com’s 2025 review of its FDD, on top of a $600 a month general advertising fee. The tradeoff cuts both ways. A flat fee doesn’t grow if your location becomes one of the system’s best performers, which favors high-volume operators. It also doesn’t shrink in your slowest month or your first quarter while you’re still building a customer base, which is exactly when a percentage-of-gross royalty would have cost you less.

Neither structure is inherently better. What matters is running your own expected sales, from Item 19 if the franchisor discloses one and from independent sources if it doesn’t, against whichever structure the brand you’re considering actually uses. For more on reading that disclosure correctly, see our guide on how to read a coffee franchise’s Item 19.

Why percentage of gross hits harder in food than in most other industries

A royalty calculated on gross sales takes the same bite whether your food cost ran 28% or 38% that month, whether a walk-in fridge died and cost you four days of inventory, or whether a slow Tuesday barely covered payroll. That’s true in every industry that charges a percentage-of-gross royalty. It matters more in food and beverage because food margins start out thinner than almost any other franchise category.

A typical independent coffee shop or quick-service food operation runs on single-digit to low-double-digit net margins after rent, labor, food cost, and overhead. When a 6% royalty and a 2% ad fund come off the top of gross sales before any of those other costs are even counted, that combined 8% has already consumed a meaningful share of what would otherwise flow toward the bottom line. Compare that to a service-based franchise with 50% or 60% gross margins, where the same 8% combined rate is a smaller bite out of a much larger cushion.

This is the mechanical reason royalty rate matters more in food franchising than the raw percentage number suggests on its own. It isn’t that food franchise royalties are unusually high compared to other industries, they generally aren’t. It’s that the margin the royalty comes out of is unusually thin, so the same percentage does more damage. If you’re weighing a food concept against a non-food one, or a franchise against running an independent shop with no royalty at all, this is the mechanism to run the numbers on rather than comparing headline percentages across categories. Our coffee franchise versus independent comparison walks through that independent-operator side of the math in more depth.

A worked example: what the combined rate actually costs on a month of sales

Here’s the mechanism laid out with real cited rates, using a round $50,000 month of gross sales as the example, a figure chosen only to make the percentage math easy to follow. This is not a claim about what any location actually makes. It’s arithmetic applied to disclosed rates.

Scooter’s Coffee	6.0%	2.0%	8.0%	$4,000	FDD detail, franchiseinvestordata.com
Toastique	6.0%	2.0%	8.0%*	$4,000*	FDD detail, vetmyfranchise.com
Caribou Coffee (Cabin/Chalet)	5.0%	up to 3.0%	up to 8.0%	up to $4,000	2025 FDD via franchisechatter.com
Dunkin’	5.9%	5.0%	10.9%	$5,450	2025-Q4 FDD, franchiseinvestordata.com
Subway	8.0%	4.5%	12.5%	$6,250	FDD Item 6, Lopes Law LLC

*Toastique also requires an additional 2% of gross sales in local marketing spend the franchisee directs, which would bring the effective total closer to 10% if you count it, per vetmyfranchise.com’s fee detail.

Want to run these numbers against your own sales estimate instead of a round $50,000 month? Our franchise royalty calculator takes the royalty and ad-fund rates from Item 6 and shows the dollar cost per year and across a ten-year agreement.

Look at the spread between Scooter’s Coffee at $4,000 off that same $50,000 month and Subway at $6,250. That’s a $2,250 difference every single month, before either franchisee has paid rent, payroll, or bought a single ingredient, on the exact same top-line sales number. Run that gap across a full year and it’s $27,000 that one franchisee keeps and the other sends to the franchisor. None of this counts the flat technology fee that rides on top in most systems now, typically somewhere in the $150 to $200 a month range for food concepts per the FranConnect data cited above, which is a smaller number but still comes out of the same gross sales before it touches anything else.

This table is not a ranking of which brand is the better investment. A brand charging 12.5% combined might be delivering national brand recognition, proven site-selection support, and same-store sales volume that a lower-royalty brand can’t match, in which case the higher rate could still be the better economic deal at the unit level. The table exists to show you the mechanism: you cannot compare two franchise opportunities by royalty rate alone, and you cannot evaluate a royalty rate at all without knowing the ad fund rate riding next to it and the technology fee riding on top of both. For a full breakdown of how these ongoing rates interact with the upfront investment number, see our Item 7 walkthrough, and for how several coffee brands stack up side by side across investment, royalty, and footprint, see our coffee franchise comparison.

What to ask before you sign, not after

The royalty rate, ad fund rate, and any technology fee are all disclosed in Item 6, but Item 6 only tells you the rate. It doesn’t tell you what you get for it. Before you treat any combined rate as acceptable or too high, get direct answers, in writing where possible, on a short list of questions.

Ask what the ad fund actually paid for last year, not what it’s supposed to pay for. Some franchise agreements let the franchisor use ad fund dollars for costs that read more like general overhead than marketing that drives traffic to your specific location. Ask whether the technology fee is truly flat or whether the agreement reserves the right to convert it to a percentage of revenue later, the way some flat-fee royalty systems reserve the right to convert to a percentage-of-gross structure with notice. Ask current franchisees, not the franchisor’s development team, whether they feel the combined rate reflects real marketing lift and real system support, or whether it feels like a toll. Our guide to questions worth asking existing franchisees has a fuller list built around exactly this kind of validation.

None of these questions have a right answer that applies across brands. A 10% combined rate attached to a system with strong same-store sales growth and real marketing muscle behind it can outperform a 6% combined rate attached to a system that isn’t investing the fund in anything that reaches your customers. The rate alone tells you what you’ll pay. It doesn’t tell you what you’ll get, and that second half of the equation is the one Item 6 was never designed to answer.
