To price a bag of kettle corn you add up its full cost first: the kernels, sugar and oil by the batch, your time at an hourly rate, the bag, and a share of overhead like rent and power. That's what one bag costs you. Then set the price so that, after card and selling fees, it leaves the margin you want: price = full cost ÷ (1 − margin − fee rate). For a large bag of kettle corn that costs $1.97 to make, a 60% margin after 3% fees means $5.32, rounded up to $5.50. At events the booth fee is the biggest cost after your time, so it goes into overhead a bag. School and team fundraisers buy at a wholesale price, set so it still covers the full cost with something left. In the example below, a Kansas kettle corn stand prices its bags for a summer of events.
The short version
- Full cost = ingredients a bag + your time + the bag + overhead.
- Price = full cost ÷ (1 − margin − fee rate).
- Count your time at a real hourly rate, even if you don't pay yourself yet.
- Put the event fee into overhead, divided by the bags you expect to sell.
- Pop in batches you can sell hot; stale bags are waste.
- Check what wholesale leaves after full cost before saying yes.
- TaroStack costs each bag from its recipe and what each batch used. More below.
What goes into a bag's cost
| Part | How to count it |
|---|---|
| Ingredients | The batch's cost ÷ bags a batch |
| Your time | Hands-on minutes for the batch ÷ bags × your hourly rate |
| Bag | Per bag |
| Overhead | Rent, power, tools, spread over the bags you make |
| Fees | Card and market fees as a share of the price |

An example: a large bag at a county fair
Prairie Pop Kettle Corn, a made-up kettle corn stand in Wichita, Kansas, pops a pound of kernels at a time into eight large bags, and spreads a $150 booth fee over the 150 bags it expects to sell:
| Ingredient | Amount | Cost |
|---|---|---|
| Popcorn kernels | 1 lb | $1.20 |
| Sugar | 0.5 lb | $0.40 |
| Coconut oil | 0.3 lb | $0.75 |
| Salt | $0.05 | |
| A batch | $2.40 |
| A bag | Cost |
|---|---|
| Ingredients, $2.40 ÷ 8 | $0.30 |
| Time, 10 minutes for the batch at $20 an hour ÷ 8 | $0.42 |
| Bag | $0.25 |
| Overhead | $1.00 |
| Full cost | $1.97 |
At a 60% margin after 3% card fees, the price is $1.97 ÷ 0.37 = $5.32, so $5.50. At $5.50 a bag, each leaves $3.37. It had been asking $6, which leaves $3.85, and kept $6 for the fair. A school fundraiser asked for bags at $3.00, which leaves $0.94 each, worth it for an order of 200 popped in the morning with no booth fee. Without the booth fee in overhead, the same bag would look like it costs a dollar less than it does. How a price becomes a margin is in what is a good profit margin for a food product.
Get the calculator
Download the popcorn price calculator. One sheet: type the batch's ingredients, amounts and costs, the bags it makes, the hands-on minutes, the bag and overhead, your hourly rate, card fees and the margin you want; the full cost, the price for your margin rounded up, and what a wholesale price and a test price leave fill in. It's an ordinary Excel file with no macros, and it works in Google Sheets, LibreOffice and Numbers.
Where this stops working
The calculator prices a bag on paper. A rainy fair day that sells 60 bags instead of 150 puts more of the booth fee on each one.
How TaroStack does it
TaroStack costs each bag from its recipe and from what each batch used.
Recipes by weight. Each bag is a recipe, with unit conversion from the case or sack to the gram.
True cost from the batch. Each batch takes ingredients at their real cost, from the deliveries they came from, so a price rise shows up in the next batch.
Price creep. A price-creep report per supplier shows which ingredient is quietly costing more.
| The job | Spreadsheet | In TaroStack |
|---|---|---|
| What a bag costs this week | Last season's sheet | True cost from the batch |
| Bags left at the end of a day | Not counted | Waste with a reason |
| An ingredient creeping up | Noticed at tax time | A price-creep report |
| Whether wholesale still pays | A guess | Margins on real cost |
Recipes, batches and true cost are on every plan, from $49 a month. The first 30 days are free, with no credit card. If you'd like a hand setting up, ask, and we'll do it with you.
