What Is the Total Cost of Ownership for a Digital Product?
The total cost of ownership for a digital product covers everything from development to decommissioning. Development itself typically accounts for 40–60 percent of the three-year cost – the rest is hosting, maintenance, further development, licenses, and support. A product that's cheapest to build can therefore end up most expensive to own, if quality gaps create extra costs after launch.
The quote shows what the product costs to build. What it costs to own is a different – and bigger – number, one few vendors volunteer. Calculate for three years instead of for delivery day, and you’ll make better decisions at almost every fork in the road.
Development is only 40–60 percent of the cost
Over a three-year period, development itself typically accounts for 40–60 percent of the total cost of ownership. The rest is split between hosting, maintenance, further development, licenses, support, and your own internal time. That means the number most people negotiate hardest over – the build price – is roughly half the story.
Calculation template: the line items to include
| Cost item | Typical level |
|---|---|
| Development (one-time cost) | 40–60% of the three-year cost |
| Hosting and operations | Varies with load and uptime requirements; from a few thousand SEK a month |
| Maintenance (bug fixes, updates, support) | 15–25% of the build cost per year |
| Further development (new features) | 20–40% of the build cost per year, depending on ambition |
| Licenses and third-party services | Payments, maps, email, analytics – often scales with usage |
| Support and internal time | Often forgotten: your own admin, product ownership, and testing time |
Go through these line items with every vendor you evaluate and ask for estimates per item. A vendor who can’t reason about the years after launch hasn’t thought it all the way through.
Worked example: cheapest to build, most expensive to own
Two quotes for the same product: A at SEK 700,000 and B at SEK 1,000,000. B’s higher price buys test automation, documentation, and a more thoroughly worked-out architecture. The numbers below are illustrative, but the mechanism is real.
Product A needs frequent bug fixing – maintenance at the top of the range, 25 percent, or SEK 175,000 a year. Further development moves slowly through the tangled codebase: SEK 300,000 a year for a moderate pace. After three years: 700,000 + 525,000 + 900,000 = roughly SEK 2.1 million.
Product B is maintained at 15 percent, SEK 150,000 a year, and the same development pace costs SEK 200,000 a year. After three years: 1,000,000 + 450,000 + 600,000 = roughly SEK 2.05 million.
The “more expensive” build is already cheaper overall after three years – and the gap grows every year the product lives, because the difference sits in the recurring line items. Add hosting and licenses, which are roughly the same size in both cases, and the conclusion holds.
Why cheap builds get expensive
- Shortcuts in the architecture make every new feature more expensive to add.
- Missing tests make every change risky – and caution costs hours.
- Thin documentation locks you to the vendor who built it, along with the pricing that comes with that.
- Skimpy testing before launch shifts the bugs to production, where they’re most expensive to find and fix.
None of this shows up in the quote. All of it shows up in TCO.
Don’t forget your own time
The most underestimated line item in the calculation is internal time: someone on your side has to prioritize the backlog, answer the vendor’s questions, test deliveries, and handle user feedback. For an active product, that’s often a significant chunk of a role. That time never shows up on an invoice – but it’s a cost, and without it, even the best vendor builds the wrong things.
Finally, account for a line item that’s almost never budgeted: decommissioning or replacement. Data has to be exported, integrations disconnected, and users migrated the day the product is replaced. It doesn’t have to cost much – if export paths and ownership were part of the requirements from the start.
How to use TCO when buying development
- Ask every vendor for a three-year calculation, not just a build price.
- Compare quotes on total cost including maintenance and hosting.
- Budget for year two right at the order stage – the product isn’t finished just because it’s launched.
- Ask what’s being done in the build to keep ownership cost down: tests, standard technology, documentation.

Frequently asked questions
How many years should a TCO calculation cover?
Three years is a common and manageable horizon for digital products – long enough for operating costs to show up, short enough to estimate seriously. For core systems with a long lifespan, many use five years instead.
How do I lower the ownership cost without lowering quality?
Choose standard technology that many developers know, use cloud services instead of running your own infrastructure, require automated tests and ongoing documentation, and avoid vendor lock-in. All of this lowers the cost for the years after launch – where most of the money is.
Is a high maintenance cost always a bad sign?
No. A product with many users and a high rate of change naturally costs more to keep in top shape, and that can be money well spent. The warning sign is a high maintenance cost without matching value – when the money keeps something afloat rather than making it better.
What does hosting an app or web service cost per month?
It varies with load and uptime requirements: simpler products often get by on a few thousand SEK a month in cloud costs, while business-critical services with redundancy, high traffic, and strict requirements cost considerably more. Ask the vendor for an estimate per environment in the quote itself.
How does TCO change if the product is built with no-code?
The starting cost drops, but platform fees, which often scale per user, replace part of the development and hosting cost. Also build an exit cost into the calculation: the logic lives inside the platform and has to be rebuilt the day you outgrow it.
