Where do the numbers come from?

From you. The calculator multiplies people × hours × rate over 46 working weeks, adds tooling costs, and compares the total against the agency quote and a Chattee plan. Nothing is sent anywhere; the URL carries your inputs so you can share it.

Vacation and public holidays. Change the assumption in your head if your team works differently; the ratio between the options does not change.

What is not in the calculation?

Revenue you might gain, risk you might avoid, and the cost of your own time specifying the tool. It is a floor, not a business case.

Yes. No account, no card, no watermark. Each visitor can run a tool a few times an hour; the limit exists only to keep the tools fast for everyone.

What happens to what I type?

Nothing leaves your browser. This calculator does the arithmetic on your own machine — no AI model, no server, nothing stored. The share link carries your numbers in the address bar, so it is yours to hand out or not.

Can I use the result outside Chattee?

Of course. Copy it, download it, share the link. "Build this with Chattee" is there if you want the app built, not a condition.

Internal Tool ROI Calculator

What the manual process costs per year, and how fast an agency build or a Chattee app pays for itself.

How it works

groups

Count the people and hours

How many people do the manual work, and how many hours a week each of them loses to it.

payments

Add the costs

Their hourly cost, what you pay for the current tooling, and the agency quote you have or expect.

show_chart

Compare payback

Lost money per year, payback months for an agency build, and payback for a Chattee app at plan price.

Where the ROI of an internal tool comes from

Rarely from the feature you had in mind. Usually from the copying.

content_copy

Re-typing between systems

Data entered twice is an hour a day for someone. That hour is the ROI.

error

Errors and their cleanup

A wrong row in a spreadsheet costs more to find than to prevent with a form that validates.

schedule

Waiting

Approvals by email, status by asking. A tool with notifications gives the waiting time back.
