What Does an Interaction Designer Cost in 2026?

I think an interaction designer costs about the same as a UI/UX designer, so an independent designer would mostly charge $25 to $120 an hour and an agency would charge $100 to $250, but the title does change what you receive for that money. An interaction designer works on how the product behaves, which means the steps in each flow, the states of each screen and what the software says back when someone uses it, and in B2B software that behaviour is really where most of the design budget should go.

This guide sets out what interaction design costs in 2026, what moves a quote up or down, how the price compares with hiring a UX strategist, and then how I price the same work myself.

The short answer

These are market rates for senior people whom you hire directly, and they match the ranges in my wider guide to what a UI/UX designer costs, because in practice the two titles are quoted from the same rate card. My own projects run $1,000 to $5,000, and I break that range down after the parts of a brief which move the price. For a salaried comparison, the US Bureau of Labor Statistics puts the median wage for web and digital interface designers at $104,000 a year in May 2025, which works out to about $50 an hour before an employer adds benefits and overheads.

What an interaction designer does for the money

A UI designer is mostly asked how a screen should look, and an interaction designer is asked what should happen when someone uses it, so the work covers the order of the steps, what each control does when it is pressed, what the screen shows while it waits for the server and what it says when something fails. The Bureau of Labor Statistics describes this group of designers as the people who create and test the layout, functions and navigation of an interface for usability, and I think the functions and the testing in that description are the parts which an interaction designer is really paid for.

That emphasis matters most in B2B software, because the people who use it spend most of their working day using it, and a flow which asks for two extra clicks on every order adds up to hours every week across a team of ten. So when a quote for interaction design looks high next to a quote for visual design, I would check whether the higher one includes the behaviour which the cheaper one leaves for the developers to decide.

What moves an interaction design quote

The number of states, which matters more than the number of screens

An orders screen in a brief would need an empty state, a loading state, a state with one order and a state with two thousand, then a failed save and a version for someone who has no permission to edit, so one screen in the brief becomes six or more designs in the file. I think this is the biggest gap between a cheap quote and a realistic one, so I would ask every designer how many states they are planning to draw and then compare the quotes on that number. I went through the same problem for tables in data table UX design, where one table with its filters and bulk actions carries most of those states.

How far the prototype goes

A clickable prototype which links the screens together is quick to make, but a prototype which behaves like the product, with real validation, conditional steps and loading delays, would take a day or more for each flow. It’s really worth paying for when you are testing the flow with users or handing it to developers who were not part of the design conversations, and I would mostly skip it when everyone already agrees on how the flow should work.

Whether testing is included

Watching people run through the flow is the part which proves that the interaction design works, and Jakob Nielsen’s research at Nielsen Norman Group found that five users uncover about 85% of the usability problems in a design. So a quote which includes a round of five sessions, and the changes which come out of them, should cost more than one which ends at the prototype, and I think it is the better value of the two because every problem found in testing is a problem which the developers would otherwise build.

Roles and permissions

Each role adds a version of every screen which it touches, so a tool with an operator, a supervisor and a customer is comfortably twice the interaction work of a tool with one role, and the hardest questions are about who can see a record and who can change it halfway through an approval. I broke that down for whole products in B2B SaaS design cost, and the same multiplier applies to a single flow.

Interaction designer or UX strategist

A UX strategist works a step earlier and is asked what the product should do and for whom, so the engagement is mostly interviews, research and a written direction, and it usually ends before anyone designs a screen. I believe a strategist mostly charges a higher day rate for fewer days, so I would expect the total for a strategy engagement to come out close to the audit row in the table above, but you would still need someone to design the behaviour afterwards, which is where the interaction designer’s quote starts.

For most B2B teams I would start with an audit which does both jobs, because an audit asks the strategic question first, whether the problem is the design, the engineering or a process which nobody has written down, and then it points at the flows which the interaction design should fix first.

How I price interaction design

I price by the project, so the price and the list of flows and states which it covers are agreed before the work starts, and there are no retainers or percentage add-ons on top. A UX audit is $1,000 to $2,000, one workflow or dashboard would be $2,000 to $4,000, a surface with several roles would be $4,000 to $5,000, and design together with the front-end build would be $3,000 to $5,000.

Those prices are lower than the market table because I work independently from the Philippines with clients in the US, Australia and Asia, and I suppose the more useful comparison for you is what each price includes, so I would always ask for the number of flows and states in writing, whoever you hire.

Frequently asked questions

Is an interaction designer more expensive than a UX designer?

Mostly no, since both titles are quoted from the same hourly range, and the difference shows in the scope of the quote. An interaction designer’s quote would usually list flows, states and prototypes, and a UX designer’s quote might also cover research and information architecture, so I would compare what each quote covers before comparing the totals.

What does a UX strategist cost?

I think a UX strategist costs about the same in total as a product audit, because the engagement is short, usually a week or two of interviews and workshops, and the day rate is higher than a designer’s. The output is a direction and a set of priorities, so you would budget separately for the design work which follows it.

Do I need an interaction designer for a B2B product?

I believe you do, whatever title the person uses, because the same people use a B2B product for long stretches of the day, and the behaviour of each flow decides how fast they can work. A designer who only draws the finished screens leaves the empty, loading and error states to the developers, and then those states are decided under deadline pressure, one screen at a time.

Should I pay an interaction designer by the hour or by the project?

By the project when the flows are known, since a fixed price makes the designer carry the risk of a bad estimate, and by the hour with a cap when the work is still exploratory. I would mostly start with a fixed-price audit and then price the workflow once the audit has shown which flows need the work.

How long does interaction design take for one workflow?

One defined workflow usually takes three to five weeks, which would cover the flow, every state, a prototype and one round of testing with the changes from it. A product with several roles would take eight to twelve weeks, and the front-end build would add three to six weeks to either of them.

A price for your own flows

If you send me the flows which your team finds slow, even as a rough list, I will tell you which of the prices above they fit and what would move them. You can see the product work which I have done in my case studies, and the audit is usually where I would suggest we start.
