Cost Structure — understanding what it really costs
Most businesses have a rough idea of their costs. Fewer have a clear one. Here's how to get honest about what your model actually costs — and what to do about it.
Do you actually know what your business costs?
It sounds like a basic question. But a surprising number of businesses have a fuzzy picture of their cost structure — which makes it very hard to price well, scale sustainably, or make smart decisions about where to invest.
The Cost Structure block covers all the costs you incur to make your business model work: creating value, reaching customers, maintaining relationships, generating revenue. Every model creates costs. The question is whether you understand them and can manage them deliberately.
Cost-driven vs. value-driven
There are two ends of the spectrum. Cost-driven businesses obsess over minimising costs — lean operations, maximum automation, lots of outsourcing. Budget airlines. Discount retailers. Low price is part of the value proposition itself.
Value-driven businesses focus on creating the best possible experience, even at higher cost. Premium hotels. Bespoke consulting. Luxury brands. Price is secondary; quality and experience come first.
Most businesses sit somewhere in between. The point isn't to pick a label — it's to be clear about which direction you're leaning, and make decisions accordingly.
Fixed vs. variable costs
Fixed costs stay constant regardless of how much you produce or sell: salaries, rent, software licences, insurance.
Variable costs scale with output: materials, transaction fees, delivery costs, usage-based cloud infrastructure.
Understanding the split matters enormously for pricing, break-even analysis, and knowing what it'll actually cost to grow.
Scale effects
Two worth knowing:
Economies of scale — your cost per unit falls as volume increases. A factory producing 10,000 units has a lower unit cost than one producing 1,000.
Economies of scope — it costs less to produce multiple things together than separately. A consultancy adding a new service can often reuse existing team knowledge, tools, and client relationships.
Common mistakes
Underestimating fixed costs is the big one, especially early on — particularly personnel costs, which almost always end up higher than expected. Mixing up investment and cost is another trap: R&D and brand-building generate future value, they're not the same as ongoing operational expenses. And cost structures drift — tools that cost €50/month two years ago can cost €500 today. Review regularly.
Questions to explore with clients
- What are your three biggest cost categories? Are they directly linked to creating value?
- What proportion of your costs are fixed vs. variable?
- Which in-house activities cost more than the value they create?
- If you had to cut 20% of costs, where would you start — and what would the trade-offs be?
- Are any costs growing faster than your revenue?
- What could you reduce by partnering differently or adopting new technology?
