How to Calculate ROI for Internal Products


Hi Reader,

Do you have a new idea for a feature.
Or a project you genuinely believe in.
And you’re thinking about pitching it to leadership.

Before you do that… pause.

There’s one thing you should do first.

Calculate the ROI.

Not because it’s fun.
Not because it’s perfect.
But because ROI is how decisions actually get made in internal product management.

Today in 10 minutes you will:

  • Understand how ROI actually works for internal products
  • Learn the value and cost drivers leadership cares about
  • See real-life ROI examples comparing value vs investment
  • Get a one-page ROI framework you can reuse for your next pitch

Why ROI matters so much for internal products

As internal product managers, we all compete for the same thing.

Budget.

Every year, I write funding requests for:
→ Team capacity
→ New initiatives
→ Technical investments
→ “Nice-to-have” improvements that are actually critical

And every single time, ROI shows up.

If you can’t explain:
→ how much you need to invest
→ versus what the company gets back

Your product is at risk.

Not immediately.
But slowly.

De-scoped.
Deprioritized.
Or quietly shut down.

A quick reality check

ROI is not the only thing that matters.

If your initiative is not aligned with:
→ company strategy
→ leadership priorities
→ long-term direction

No ROI will save it.

But without ROI?
Even strategically important work struggles to survive.

The ROI formula… in PM language

At its simplest, ROI has two sides:

→ Value (what the business gets)
→ Cost (what the business invests)

That’s it.

The challenge is understanding what belongs on each side for internal products.


The value side of ROI

Value in internal products rarely shows up in just one place.
These are the four value types I look at when building an ROI view.

1. Revenue drivers

If your internal product helps revenue-generating teams, it contributes to revenue.

Examples:

→ Removing manual steps in sales workflows
→ Speeding up deal cycles
→ Reducing errors in pricing or contracts
→ Increasing the number of deals a team can handle
→ Enabling better decisions through better data

You’re not saying: “This product generates €X in revenue.”

You’re saying: “This product enables revenue by removing friction.”

That distinction matters. And leadership understands it.

2. Productivity gains

This is the most common and reliable value bucket.

Ask:
→ Who uses the product?
→ How often?
→ How much time does it save per user?

Five minutes saved per person sounds small. At scale, it isn’t.

3. Cost reduction

Examples:
→ Manual work removed
→ External tools or licenses retired
→ Reduced support or incident effort
→ Lower dependency on vendors

This value is usually the easiest to defend.

4. Cost avoidance (often invisible, still critical)

Examples:
→ Security or compliance risks avoided
→ Revenue loss prevented through fewer errors
→ Audit findings avoided
→ Future scalability issues prevented

It’s not flashy. But it matters a lot in enterprise environments.


The cost side of ROI (where many PMs undercount)

When PMs talk about cost, they usually think:

“Development.”

That’s only part of the picture.

For internal products, cost shows up in multiple places.

1. Build cost

The obvious one.

Include:
→ Engineering time
→ Product management time
→ Design and architecture support

I usually estimate this as:
→ people × months × rough cost

Precision is less important than transparency.

2. Change and rollout cost

Internal products don’t ship themselves.

Include:
→ Training and enablement
→ Documentation
→ Stakeholder communication
→ Data migration or clean-up
→ Temporary productivity dip during transition

This is especially important for tools that change daily workflows.

3. Ongoing maintenance cost

After launch, the product still exists.

Include:
→ Bug fixing and support
→ Incident handling
→ Infrastructure and licenses
→ Small but continuous improvements

Leadership cares about this because it compounds over time.

4. Opportunity cost

The uncomfortable one.

Ask:
→ What are we not building if we build this?
→ Which team capacity is locked here?
→ What trade-offs are we making explicit?

You don’t need perfect numbers.
You just need to acknowledge it.


Real-life ROI examples (value vs cost)

Below are three examples that show how I usually phrase ROI in practice.

Example 1: Sales enablement

“This product reduces manual sales administration by ~10 minutes per deal.
At ~2,000 deals per year, this frees up ~330 hours of selling time annually.
At an estimated €X per hour, this equals approximately €Y per year in enabled capacity, compared to an investment of €2,000.
This does not directly create revenue, but it removes friction in the sales process and supports faster deal execution.”

Example 2: Operational automation

“This automation removes ~15 minutes of manual work per case.
At ~8,000 cases per year, this frees up ~2,000 hours annually.
At an estimated €X per hour, this equals approximately €Y per year in enabled capacity, compared to an investment of €Z.
This does not create direct revenue, but it reduces operational load and allows the team to scale without additional headcount.”

Example 3: Reliability or compliance investment

“This investment reduces the likelihood of incidents that cause service disruption or compliance exposure.
Based on comparable past incidents, recovery and mitigation efforts typically cost approximately €Y per year.
Compared to an annual investment of €Z, this reduces downside risk and improves overall operational stability.”

One-page ROI summary

If this felt like a lot to take in, that’s normal.

This infographic is a one-page summary of everything we just covered:
→ how to think about value
→ how to think about cost
→ and how to frame ROI for internal products

It’s the exact structure I use when preparing budget proposals or leadership conversations.

Behind the Scenes

Have you set your New Year resolutions yet?

I’m trying something different this year.

I got inspired by a podcast episode by Mel Robbins and Emma Grede, and instead of setting big goals, I’m focusing on being more kind with my own mind.

I noticed how quickly my thoughts go negative, especially towards myself.
So this year, I’m consciously trying to steer that inner voice in a more supportive direction.

No big resolutions.
Just a gentler way of showing up for myself.

What do you think?

Does ROI still feel uncomfortable to work with?
Or has it become part of how you think about product decisions?

See you next week,
