A food business falls into a growth trap when it adds sales that earn less per hour than what it already sold. It happens with high-commission channels, low-price wholesale orders, discounts that buy volume and new products that eat kitchen time. Sales go up, the workload goes up, and what you keep at the end of the month barely moves. One number catches it: contribution per kitchen hour. If sales rise while that number falls, you are growing in the wrong direction.
Why selling more can leave you with less
A small kitchen has two limits: money and hours. Most people only watch the money. An order for 300 jars looks great because it brings in $1,650 of sales. But if it takes 45 hours you could have spent making and selling your own product at a better price, it can leave you worse off than before.
That is why the number that matters is contribution per kitchen hour: total contribution margin divided by the hours it took. The guide on contribution per kitchen hour shows how to work it out for each product.
The six most common traps
1. Volume in a channel that pays little. Delivery apps with high commissions, shops that want wholesale prices, consignment. Each channel has its own contribution per unit. Before you grow in one, compare it with the others. The guide on comparing profit by channel sets out the method.
2. Discounts that buy sales. A 20% discount can fill your order book and still leave you with less contribution than before. The guide on what a discount really costs you shows how many extra units you need just to break even on it.
3. More products, more hours. Every new product brings different shopping, another prep routine, more cleanup. If the newcomer earns less per hour than your existing range, it is taking hours that were worth more.
4. Costs that jump in steps. Up to a certain volume you can do it alone in your kitchen. One step further and you need a helper, a second oven or a bigger space. That cost arrives all at once, not gradually. The guide on when to hire your first helper helps you see where that point is.
5. Growth that eats your cash. More sales mean more ingredients bought before you get paid. If your big new customer also pays at 30 days, you can be profitable on paper and short of money for Monday's shop. That is the problem explained in why you can be profitable and still have no money.
6. Making too much. When sales are growing, it is tempting to produce for the sales you expect rather than the ones you have. Waste climbs quietly. The guide on production planning explains how to work out how much to make each week.
Worked example: the big granola order
You sell 500 g jars of granola direct, at markets and online. Price: $9.00. Variable cost: $3.60 a jar for oats, nuts, honey, the jar, the label and waste. Contribution: 9.00 − 3.60 = $5.40 a jar. You sell 120 jars a month, and they take 24 kitchen hours.
A local grocery chain offers to take 300 jars a month at $5.50 each. They want shelf-ready cases and you deliver. That adds $0.30 a jar for shelf labels, cases and fuel. Contribution per grocery jar: 5.50 − 3.60 − 0.30 = $1.60. Making and delivering the 300 jars takes another 45 hours a month.
| Direct only | Direct + grocery | |
|---|---|---|
| Jars a month | 120 | 420 |
| Sales | 120 × 9.00 = $1,080 | 1,080 + 300 × 5.50 = $2,730 |
| Contribution | 120 × 5.40 = $648 | 648 + 300 × 1.60 = $1,128 |
| Kitchen hours | 24 | 69 |
| Contribution per hour | 648 ÷ 24 = $27.00 | 1,128 ÷ 69 = $16.35 |
What the table shows:
- You make 250% more jars (from 120 to 420).
- Sales rise 153% (2,730 ÷ 1,080 = 2.53).
- Contribution rises 74% (1,128 ÷ 648 = 1.74).
- But you work almost three times the hours (69 against 24), and each hour earns $16.35 instead of $27.00.
Look at the new hours on their own: 480 ÷ 45 = $10.67 an hour. Each hour spent on grocery jars earns well under half of an hour spent on direct jars.
And the cash. The chain pays at 30 days. Before the first payment arrives you have to put up 300 × (3.60 + 0.30) = $1,170 for ingredients, jars, labels and fuel. If you do not have that money, the "big break" leaves you without the stock to serve your own customers.
The price that would work. Decide what you want each kitchen hour on this order to earn. Say $20.00. Over 45 hours that is 45 × 20 = $900. Spread over 300 jars: 900 ÷ 300 = $3.00 contribution per jar. Floor price: 3.00 + 3.60 + 0.30 = $6.90. Now you can negotiate: ask for $6.90, offer fewer jars at an in-between price, or say no knowing exactly why.
If you could sell more jars direct in those 45 hours, the case is even clearer: each direct jar leaves $5.40 against $1.60. But only if those customers exist. If they do not, the real question is whether $10.67 an hour beats resting or doing something else with that time.
How to decide before you say yes
Before taking on a new channel, a big order or a promotion, answer four questions:
- What does it earn per kitchen hour? Compare it with what you already do.
- Where do the hours come from? Spare time, your rest, or time you now spend on direct sales.
- How much cash goes out before you get paid? And do you have it.
- Which cost jumps at this volume? A helper, a freezer, more kitchen rental, a bigger space.
If all four answers work, grow. If not, negotiate the price, shrink the volume or wait. The guide on how to grow a small food business sets out the kinds of growth that usually earn more per hour.
Do it with the calculator
Put your recipe into the food cost calculator and try the price for each channel: direct, wholesale or app. You see the contribution per unit for each and can compare them before you accept the order.
Frequently asked questions
How do I know if I am in a growth trap?
Track your contribution per kitchen hour week by week. If sales go up while that number goes down, you are growing with something that earns less per hour than what you already did.
Should I ever accept a big order at a low price?
You can, if you know what it earns per hour, you have spare hours you would not otherwise use, and your cash can cover the ingredients before you are paid. The danger is saying yes without doing those three sums.
What is the lowest price I should quote a wholesale buyer?
Decide what you want to earn per kitchen hour, multiply it by the hours the order will take, divide by the number of units and add the variable cost per unit. That is your floor.
Are delivery apps a growth trap?
Not by themselves. They become one when the commission leaves a contribution per hour far below your direct sales, and the app orders start taking hours you used to spend on direct customers.
