Should You Start a Gas Station or Convenience Store?

How much money does fuel actually make?

Retail gasoline gross margins fluctuate, often in the range of 25 to 45 cents a gallon before card fees, and swing sharply when wholesale prices move. Credit and debit fees take a bite: at 2.5 percent on a $3.50 gallon, processing costs about 9 cents, and that comes off before rent, labor, and utilities. Net fuel margin after fees is often only a dime or two per gallon. A site selling 100,000 gallons a month at a 12-cent net margin makes about $12,000, which is why fuel mostly covers itself and pulls customers inside. Volatile wholesale prices can wipe out a month's margin in a week.

Where does the profit really come from?

Inside sales carry higher margins than fuel: packaged beverages and snacks often run 30 to 45 percent gross margin, fountain drinks and coffee far higher, and prepared food frequently above 50 percent, while cigarettes, still a big share of sales at many stores, carry much thinner margins in the low teens. Beer and wine sit in between. A store that builds strong foodservice and beverage programs can produce most of its gross profit inside, even though fuel makes up most of the revenue. Model each category separately when you evaluate a site, and be skeptical of blended margins.

Should you buy a branded, unbranded, or franchised site?

Branded fuel programs from major oil brands typically come through supply agreements with a distributor or jobber, often with volume minimums, image and equipment requirements, and sometimes incentive payments that must be repaid if you leave early. Unbranded stations buy at the rack or from a wholesaler with more pricing freedom and less brand pull. Convenience franchises, such as 7-Eleven-style programs, involve separate franchise fees and royalties. The federal Petroleum Marketing Practices Act protects certain franchisees from unfair termination or nonrenewal. Have an attorney read the supply agreement before you sign, focusing on term, exclusivity, minimums, and liquidated damages.

What is the environmental risk?

Underground storage tanks (USTs) are the largest hidden liability. Federal rules in 40 CFR Part 280 and state programs require leak detection, spill and overfill prevention, operator training, periodic testing, and financial responsibility, and cleanup of a leak can cost six or seven figures. Older single-wall tanks are a red flag, and replacing a tank system can cost several hundred thousand dollars. Order a Phase I environmental site assessment before buying, and a Phase II with soil and groundwater sampling if the history is uncertain. Some states offer UST trust funds that help with cleanup costs, but eligibility depends on compliance and timing.

What does break-even look like, and what makes a station fail?

Many buyers plan for two to four years to earn back the investment on a well-located site, depending on price paid, debt terms, and how fast inside sales grow. Failure usually comes from paying too much for a site whose fuel volume was overstated, being locked into a poor supply contract, an unexpected tank or compliance bill, weak management of overnight staff and shrink, or a new competitor such as a large travel center or warehouse-club fuel site. Before buying, model a downside case with fuel volume 15 percent lower and a tank repair reserve.

Who should think twice before buying one?

This is an operations-heavy business with long hours, cash handling, and 24-hour exposure to theft and robbery risk. If you cannot commit to being on site or to hiring and supervising a strong manager, the store is likely to leak money through shrink and staffing problems. It is also a poor fit if you lack reserves, since a tank repair, a pump upgrade, or a sudden drop in fuel margins can arrive in the same year as your loan payments. First-time buyers often do better working in a store as an assistant manager for six to twelve months, learning ordering, cash controls, and the lottery, tobacco, and alcohol rules before buying.

What should the first year look like?

In the first 90 days, keep the existing staff and systems in place, learn what sells at which hours, and review daily cash and tank reconciliation yourself. In months four through twelve, fix the biggest margin gaps: renegotiate vendor terms, tighten ordering with wholesalers such as McLane, Core-Mark, or Eby-Brown, adjust the beverage and foodservice mix, and clean up the store. Avoid big remodels until you understand the customer base. Track weekly fuel gallons, net cents per gallon, inside sales per customer, shrink, and labor as a percent of sales, and keep a cash reserve for surprises.
