To be absolutely clear: the adjusted EBITDA of $485,100 is not the franchisee’s take-home pay. Instead, it’s the profits the franchise generates on average, taking into account COGS, labor costs, rent and royalty and marketing fees. As such, this adjusted EBITDA doesn’t include other expenses (like bookkeeping, taxes, debt interest, etc.).
Profit-and-loss | Amount ($) | As % of sales |
---|---|---|
Sales | $1,617,000 | 100% |
COGS | $(404,250) | 25%* |
Labor | $(468,930) | 29%* |
Rent | $(129,360) | 8%* |
Royalty + marketing fees | $(129,360) | 8% as per FDD |
Adjusted EBITDA | $485,100 | 30% |
In order to look at the take home pay (the dividends to the franchisee), we need to estimate instead net profits which we estimate at $242,550 per year (15% of sales).
Is a Sonic Drive-In franchise a good investment?
So you would make $242,550 profits per year as a Sonic Drive-In franchisee on average. But does it justify the investment cost of $1,467,083?
In order to assess whether opening a Sonic Drive-In is a good investment, we need to consider the payback period: the time it would take you as the franchisee to recoup your original investment.
Unfortunately, the payback period for a Sonic Drive-In is 6 years as per our calculations. So it would take you 6 years on average to reimburse your original investment of $1,467,083. Even though not necessarily mediocre, it is average.
Yet, note that this number is an average of the 3,184 stores. Therefore, your franchise may be more successful than the average, which would improve your payback period. In order to find out whether your franchise store is a good investment, download our template below.
