Margin-based royalties align franchisor and franchisee incentives when COGS fluctuates, which is why many modern wellness systems calculate on gross margin instead of top-line revenue alone. Note that the effective rate on the margin model is lower than the headline royalty rate, because it applies to margin rather than revenue.

How this is calculated
This tool compares the three royalty structures a wellness franchisor might use, on the same revenue, so you can see how much the basis matters.
- Gross margin = monthly revenue × (1 − COGS%). COGS is your cost of goods and services sold: product, consumables, and in some models direct service labor. Define it the same way every month.
- Revenue royalty = monthly revenue × royalty rate. The classic model: simple to audit, but it ignores how much margin the location actually keeps.
- Margin royalty = gross margin × royalty rate. Ties the fee to profitability, so it feels fairer in COGS-heavy concepts.
- Flat fee = the fixed monthly amount you enter, regardless of revenue.
- Ad fund = monthly revenue × ad fund rate. Usually billed separately from the royalty.
- Effective royalty rate = royalty owed ÷ monthly revenue. On the margin model this is lower than the headline rate, because the rate is applied to margin, not revenue.
Worked example
At $85,000 monthly revenue with 28% COGS and a 6% rate: gross margin is $61,200. A revenue royalty is $5,100/mo (6.0% effective), while a margin royalty is $3,672/mo (about 4.3% effective). Same headline rate, very different bill.

Royalties are the core of the franchisor–franchisee relationship, and how they are structured changes who carries the risk. A percentage of gross revenue is simple to administer but can squeeze a low-margin location; a margin-based royalty aligns the franchisor with unit profitability; a flat fee is predictable but regressive as a location grows.
This calculator puts the three common models side by side on your own revenue and cost assumptions, so franchisors can design a fee that scales and franchisees can see what a headline rate actually costs them.
The formula
Revenue royalty = gross revenue × rate. Margin royalty = (gross revenue − COGS) × rate. Flat fee = fixed monthly amount, shown as an effective % of revenue.

Frequently asked questions
- What is a typical franchise royalty rate?
- Wellness and fitness franchise royalties commonly run 5%–8% of gross revenue, often plus a separate marketing/brand-fund contribution of 1%–2%. Rates vary widely by concept and by what support the franchisor provides.
- Why would a franchisor use a margin-based royalty?
- Margin-based royalties tie the franchisor's revenue to unit profitability, so the brand only prospers when franchisees do. They are harder to audit than revenue-based royalties, which is why most brands still default to a percentage of gross.
- When does a flat fee favor the franchisee?
- A flat monthly fee becomes cheaper as a percentage of revenue the more a location earns, so high-volume units benefit while smaller units effectively pay a higher rate.
