How to Do Food Costing That Reflects The Reality of Your Food Business

Most food manufacturers know their food costs. At least, they think they do.

You have a spreadsheet, and it shows you the cost per unit (there’s a formula behind it). It feels like everything is under control, right? Yes, until your finance reports tell you otherwise.

There’s a difference between knowing what a product should cost and knowing what it actually costs to make — today, with this week’s prices inputs, after yesterday’s batch. The problem is, many manufacturers are tracking the first number and calling it the second.

In this guide, I explain how to get to the second number and keep it accurate as operations change.

TL; DR

• Most food manufacturers calculate product costs in spreadsheets. Those numbers go stale the moment production moves on.
• The gap between what a product should cost and what it actually costs to make is where margins disappear.
• This is the difference between static costing (a point-in-time estimate) and dynamic costing (a live number connected to your actual ops).
• This article walks you through five steps to set up dynamic costing on the example of FlexiBake, our ERP software for food and beverage companies.

The Standard Food Costing Method, and What It Can’t See

For many food manufacturers, it all starts the same way: a spreadsheet. Sometimes it evolves into a dedicated costing tool. Sometimes things get sophisticated: that same spreadsheet feeds a Power BI dashboard that looks impressively like a real system.

As for our own clients at FlexiBake (we build an ERP for food and beverage manufacturers), 8 in 10 ran their entire business in Excel before switching — ordering, production, inventory, and somewhere in the middle of all that, food costing.

Usually, it’s a giant spreadsheet file that frequently breaks: an ingredient price master, recipe tabs that pull from it, sometimes a pricing layer on top. The more careful builders add functions like vlookups so ingredient prices auto-populate across every recipe when updated.

When built carefully, spreadsheets work as a lightweight costing engine, with the final cost number driving pricing decisions, margin reviews, and production planning. The problem is that “built right” is the easy part. Keeping it right as ingredient prices shift, suppliers change, and production moves on is where it starts to go awry.

Roggenart, a Maryland bakery bistro, had a similar system with Excel for recipes and costs. But when it came to the actual cost per unit? Well, it was anyone’s guess:

The answer “We didn’t know” is more common than most manufacturers would admit. Here’s why.

The Problem: Your Spreadsheet Doesn’t Know What Changed

Take a blueberry muffin. You have the recipe, entered every ingredient. The spreadsheet says it costs $0.85 to make. You set your price, build in a 70% margin, and move on.

Three months later, butter is up 15%. A batch ran longer than scheduled, and your packaging supplier raised the prices. The actual margin, with this week’s inputs, might be 30%. Or 10%. Or nothing.

The spreadsheet still shows 70%. And you still think the muffin costs $0.85 to make.

Production doesn’t stand still, and the spreadsheet captures none of what changed automatically. Someone has to update it manually. And in a busy operation, that rarely happens as often as it should.

Static vs Dynamic Costing, and What Difference It Makes

You can think about food costing in two ways: static (the example above) and dynamic. The difference between them is why most manufacturers end up with margin surprises.

Static costing answers: what should this product cost? It’s spreadsheet-based, built around a fixed recipe at a point in time. You enter your ingredients, add labor and packaging, set an overhead percentage, and get a number. That number is accurate the day you build it.

Dynamic costing answers: what did this product actually cost? It integrates costing with your actual operations: recipes, purchasing, inventory, production, labor, packaging, waste. When anything changes, the numbers reflect it.

Here’s what that looks like in practice:

Before moving to the how-to, it’s worth checking where your current costing actually stands. If you’re not sure whether your theoretical and actual costs are aligned, this template will show you.

If the template shows a gap (or if you already suspect one exists), you can close it by applying a dynamic food costing method. It may sound like a big shift, but in practice, it’s several connected steps in your ERP. Since we can only speak of FlexiBake, here’s how it works in our own software.

Let’s Make a Muffin, Shall We? Dynamic Food Costing in Action

Take our muffin again. You know what goes into it. You’ve made it a thousand times. But do you know what it actually costs to make with today’s ingredient prices, after today’s batch?

Work through these five steps and you will. By the end, your costs will reflect what’s actually happening in your kitchen, and not what you estimated when you first wrote the recipe.

Step #1: Standardize Your Recipes

Your muffin recipe calls for flour. But how much? Ask three bakers, and you’ll get three answers. Everyone knows how to make it, but “roughly a cup” isn’t a number you can cost.

That’s why standardizing your recipes is the first step. By it, I mean documenting your recipe in an ERP with fixed ingredients, fixed quantities, and a fixed batch size.

In FlexiBake, this happens in three steps:

1) First, you add each ingredient as a raw material: flour, blueberries, butter, eggs.

2) Then you build the recipe by pulling those ingredients in with exact quantities.

3) Then you link the recipe to the product it produces: the muffin.

That’s the chain the whole costing system runs on.

Case in point: When Zehnder’s of Frankenmuth Bakery in Michigan first moved to FlexiBake, their recipes lived mostly in people’s heads. When a key person wasn’t in, production got inconsistent, and so did the costs. After formalizing every recipe in FlexiBake, they got a reliable baseline to track costs against.

At this point, every baker works from the same spec, and FlexiBake has a fixed starting point to calculate from.

Step #2: Add Every Cost That Goes Into Making Your Product

The recipe tells you what goes into the dough. But to get a sellable muffin out the door, you also need the box it ships in, the person who mixed the batter, and the cost of running the facility for that hour.

Most manufacturers start with ingredients only (it’s the easiest data to enter, after all) and never get around to the rest.

There are four inputs that make up the real cost of your muffin:

• Ingredients: already in the recipe from Step 1
• Packaging: the box, bag, or label. Added the same way as ingredients.
• Labor: for the recipe (mixing, shaping, baking) and for the product (finishing, decorating, packaging). Tracked as time-based estimates per recipe that contribute to the total cost per unit.
• Overhead: rent, utilities, equipment maintenance. In FlexiBake, this is set as a cost per person per hour and allocated across production automatically.

Once all four inputs are added, the Product Detailed Costing Report gives you a full breakdown of what your muffin costs to make.

This is your theoretical baseline — what the muffin costs when everything goes to plan. Step 3 is where you find out if it does.

Step #3: Track What Happens in Production

Your muffin is in the system. It says a batch should produce 200 units. You run production. At the end of the day, you have 188. Where did the other 12 go?

The gap between what you planned and what you actually made is where your real cost lives:

• Ingredient consumption: did production use exactly what the recipe specifies, or a little more?
• Waste: ingredients consumed that didn’t become the finished product
• Yield loss: what goes in doesn’t always equal what comes out. Bread loses moisture in the oven. Batter sticks to bowls.
• Batch variation: the same recipe doesn’t always produce the same output, especially across different shifts or equipment.

In FlexiBake, when production is done, your team enters the actual quantity produced. The system then compares that against what was scheduled. The Production Costing Detail Report shows you exactly that: units scheduled vs. units produced, batch by batch. The difference is your yield loss and waste, in measurable form.

Case in point: Before FlexiBake, Roggenart, a Maryland bakery with nine locations, couldn’t measure what was going into production. After introducing ingredient pre-scaling and closing inventory daily, they gained clear inventory visibility across all locations and avoided $60+ per batch in waste.

At this point, FlexiBake knows what your muffin actually costs to make today, not what you thought it’d cost when you wrote the recipe.

Step #4: Keep Materials Prices Up to Date

Your muffin recipe uses butter. You priced it at $4.20 — the price your supplier charged three months ago. Since then, they’ve raised it twice. Your spreadsheet doesn’t know that. The fix is connecting purchasing directly to costing so that price changes flow through automatically. Here’s how that connection works in FlexiBake:

→ When you link a supplier to a raw material, you set a price for that ingredient from that supplier.
→ When you create a purchase order, that price pre-populates automatically.
→ When the delivery arrives, and someone processes the receipt, they confirm the actual unit cost.

If the supplier charged more, they update it at that moment, and that new price flows into your recipe costing automatically. The price correction happens as part of receiving the delivery, something your team was already doing.

This is exactly what made the difference for Zehnder’s Bakery. Before FlexiBake, they tracked ingredient costs manually, and those were frequently out of date. After connecting purchasing to costing, they could make sourcing decisions based on what ingredients actually cost, and not what they cost six months prior.

At this point, FlexiBake lets you know what your ingredients actually cost at the moment.

Step #5: Check Your Numbers Regularly

Remember the static costing problem from earlier: a number that’s accurate once, then slowly drifts out of date? Step 5 is exactly where you prevent that.

Costs drift even when everything is configured correctly. A new staff member uses more flour, a supplier raises prices between deliveries, and a batch runs longer than planned. None of these are disasters on their own. But if you only look at your margins once a quarter, by the time you notice something’s off, it’s been off for months.

That’s what the Analysis Center reports are for in FlexiBake. They reflect what’s happening in your business and update continuously as you receive deliveries, record production, and process orders. A quick weekly check is all it takes.

In FlexiBake, doing dynamic costing comes down to three questions:

1) Did ingredient prices change? Review your ingredient price history against what you’re actually paying now. If butter crept up across three deliveries, this is where you see it, pulled directly from your receiving records.

2) Did your product costs shift as a result? Compare your muffin’s current cost against the previous month. Then go one level deeper: are you still making money on it? The Detailed Product Standard Margins report shows margins broken down by every cost input. If butter prices went up and your margin dropped, this is where you see it in dollars and as a percentage.

3) Is production running as expected? Check the gap between what you scheduled and what you actually produced. If your muffin consistently yields 8% below plan, you’re spending more per unit than your costs reflect. Same check for labor: if batches are regularly running longer than scheduled, your labor cost per unit is off, too.

At this point, you know if your margins are holding, and where to act if they’re not. This is dynamic costing in practice. Not a spreadsheet you update when you remember to, but a system that tracks what’s happening and shows you where to act.
