How Gas Station Profit Is Calculated
1. Fuel gross profit
Gallons sold x margin per gallon. Fuel revenue on its own is misleading — a $400,000 fuel month at $0.18 a gallon is still only about $20,000 of profit.
2. Inside gross profit
Store sales x inside margin. Cigarettes run thin, fountain and food service run rich, so blended margin usually lands between 25% and 35%.
3. Commissions and expenses
Add lottery, ATM and air/vac commission, then subtract payroll, rent, utilities, card fees and maintenance to reach real net profit.

Frequently Asked Questions
How do you calculate gas station profit?
Gas station profit is fuel gross profit (gallons sold x margin per gallon) plus inside gross profit (store sales x inside margin percentage) plus lottery and other commissions, minus operating expenses such as payroll, rent, credit card fees and utilities.
How much profit does an average gas station make per month?
It depends almost entirely on volume and inside sales mix. A site selling 100,000 gallons a month at a $0.20 margin earns $20,000 in fuel gross profit; inside sales of $80,000 at a 30% margin add another $24,000. Operating expenses then determine what is left as net profit.
Do gas stations make more money on fuel or inside sales?
For most sites inside sales generate more gross profit than fuel, because merchandise margins run 25-50% while fuel margins are usually $0.10-$0.30 per gallon. This calculator shows the split so you can see which side of your business is carrying the store.
Should lottery ticket sales count as gas station revenue?
No. Only the commission you keep is yours. Ticket sales are collected on behalf of the lottery, so enter lottery commission only when calculating profit.
