A street food price has two jobs: leave you enough on each item, and be quick to pay. So the method has three steps: work out the price you need from your cost, move it to a round number that is paid with one note or one tap, and adjust the portion so the contribution holds. Then compare the options by what they leave you per hour of trading, not just per item.
Why round prices sell faster
At a taco cart at lunchtime, the bottleneck is not always the griddle. Often it is the till: finding coins, counting change, keying in $9.75. With a round price the customer orders, pays with a note or a tap, and moves on. You go to the next one.
A few seconds per sale sounds like nothing. But if you serve 28 orders an hour at the rush instead of 32, that is four orders lost every hour, every day.
A round number is also easy to read from the back of the queue and needs no explaining. The guide to price psychology for small food businesses covers when prices ending in .99 make sense and when they do not; on the street, round numbers usually win.
Step 1: the price you need
Start with the cost of the item: ingredients, sauce, packaging, napkin. Weigh the portion. With that cost and the margin you want, the price comes from:
price = cost ÷ (1 − margin)
The plate price tool does this sum from your cost and your target percentage. The guide to setting a price that hits your target margin explains the formula.
The answer is almost never round. It might be $3.25 or $6.80. That number is your reference, not the price on your board.
Step 2: round it and adjust the portion
You have three routes:
- Round up and keep the portion. You make more per item; you need to see whether customers pay it.
- Round down and keep the portion. You lose a little per item and gain speed, maybe customers.
- Round up and make the portion bigger, or round down and make it smaller, so the contribution lands where you need it.
If you change the portion, do it with scales. Weigh the meat, use the same scoop for salsa every time. Without that, portions creep up on their own at the rush. The guide to portion control has the method.
Step 3: compare per hour, not just per item
The final question is what each hour of your rush leaves you:
contribution per hour = (price − item cost) × items served per hour
You measure items per hour yourself, with a watch, on normal days. If the round price lets you serve faster, you can make more per hour while making less per item.
Worked example: tacos at lunchtime
You sell tacos from 11:30 to 2:30 near an office park, and most people order three. One taco costs you $1.30 in tortillas, meat, toppings and packaging, from your weighed portions. Three cost $3.90. You decide you want a 60% margin:
1.30 ÷ (1 − 0.60) = 1.30 ÷ 0.40 = $3.25 per taco
These are your options for an order of three, with the orders per hour you measured:
| Option | Price for 3 | Cost for 3 | Contribution per order | Orders per hour | Contribution per hour |
|---|---|---|---|---|---|
| A: exact, $3.25 each | $9.75 | $3.90 | $5.85 | 28 | $163.80 |
| B: 3 for $10 | $10.00 | $3.90 | $6.10 | 32 | $195.20 |
| C: 3 for $12, more meat | $12.00 | $4.80 | $7.20 | 32 | $230.40 |
How the numbers come out:
- A: 3 × 3.25 = 9.75; 9.75 − 3.90 = 5.85; 5.85 × 28 = 163.80. Every cash sale needs a quarter back.
- B: 10.00 − 3.90 = 6.10; 6.10 × 32 = 195.20.
- C: you add $0.30 of meat per taco, so the cost becomes 3 × 1.60 = 4.80; 12.00 − 4.80 = 7.20; 7.20 × 32 = 230.40.
Option B leaves 195.20 − 163.80 = $31.40 more per hour than A. Over your 3-hour rush, $94.20 more a day.
Option C leaves more still, if people pay $12 at the same pace. You will not know until you try. Run it for a week and compare with your sales log.
Sizes: few and clear
Two or three options with round prices beat one with an odd price. For example:
| Option | Price | Cost | Contribution |
|---|---|---|---|
| One taco | $3.50 | $1.30 | $2.20 |
| Three tacos | $10.00 | $3.90 | $6.10 |
| Plate: five tacos with rice and beans | $16.00 | $7.70 | $8.30 |
The plate cost is 5 × 1.30 = 6.50 for the tacos plus $1.20 for rice and beans. Each option needs its own weighed portion and its own cost. More than three sizes, or lots of extras at different prices, slows the queue again.
Combos at a round price
Three tacos and an agua fresca for $12 are as quick to pay as the tacos alone. If the drink costs you $0.70, the combo leaves 12.00 − 3.90 − 0.70 = $7.40, more than the three tacos alone at $10. Always work out the contribution of the whole combo, as in combos and add-ons at a stall.
Taking payment is part of the price
Keep enough change for your round prices and the card reader charged and ready. If you pay a card fee, it lowers your contribution per item, so take it off before comparing options. All of that is in cash, card readers and change, and the guide to street food profit ties price to daily costs, waste and weather.
Do it with the calculator
Cost your item with the food cost calculator, get the reference price, then try two or three round prices and time how many you serve per hour at each one.
Frequently asked questions
Should I charge $4.95 or $5 at a stall?
At a stall the round number usually wins. $4.95 means coins and counting change on every cash sale, and at the rush those seconds become people leaving the queue.
Does rounding down lose me money?
A little per item, but if you serve faster you can make more per hour. Work it out with your contribution per item and the number you really serve per hour at each price.
Most customers pay by card. Do round prices still matter?
Less for change, but a round price is still quicker to read off the board, quicker to key in and easier to bundle. Time a few rushes at each price and let your own numbers decide.
How often should I review my street food prices?
Whenever your main ingredients go up. Recost the item with your new receipts and check that your round price still leaves the contribution you need.
